# shiro-neko
|
||||
|
||||
Agentic coding CLI, built with Bun + TypeScript. The interactive UI is React rendered to the
|
||||
terminal with Ink; LLM access goes through the Vercel AI SDK (`ai`) with Anthropic, OpenAI,
|
||||
OpenAI-compatible, and MCP providers. Entry point and only executable is `src/cli.tsx` (bin `shiro`).
|
||||
|
||||
## Commands
|
||||
|
||||
- `bun install --frozen-lockfile` — install deps (CI uses this; lockfile is `bun.lock`)
|
||||
- `bun run shiro` — run the CLI from source (i.e. `bun run src/cli.tsx`)
|
||||
- `bun test` — full test suite (`bun:test`, no other runner)
|
||||
- `bun run typecheck` — `tsc --noEmit`; must pass before committing
|
||||
- `bun run build` — `bun build --compile` to `dist/shiro` (single native binary)
|
||||
- `bun run release` — cross-compile all five targets into `dist/release/`
|
||||
- No linter or formatter is configured; don't invent one.
|
||||
|
||||
CI (`.github/workflows/ci.yml`) runs install → typecheck → test → build on Ubuntu, macOS, and
|
||||
Windows, pinned to Bun 1.3.14. Everything must be cross-platform: the tools shell out to the
|
||||
platform shell, and paths in code and tests go through `node:path`, never hardcoded `/`.
|
||||
|
||||
## Layout
|
||||
|
||||
- `src/` — flat modules, one concern per file, lowercase names (`session.ts`, `prune.ts`).
|
||||
`src/ui/` holds the Ink components, PascalCase (`App.tsx`, `Panels.tsx`).
|
||||
- `test/` — one `<name>.test.ts` per `src/<name>.ts`; `*.test.tsx` for UI tests via
|
||||
`ink-testing-library`. `test/helpers.ts` has `testHooks()`, the standard App fixture.
|
||||
- `docs/` — user-facing docs, one per feature area.
|
||||
- `scripts/` — `release.ts`, `install.ts` (+ `.sh`/`.ps1` installers).
|
||||
- `src/version.ts` — hardcoded VERSION; the release workflow fails if it disagrees with the git tag.
|
||||
|
||||
## Conventions
|
||||
|
||||
- ES modules, `verbatimModuleSyntax` on: import types with `import type`. Strict TS with
|
||||
`noUncheckedIndexedAccess` — indexing gives `T | undefined`, so handle it (`arr[i]!` appears
|
||||
where provably safe).
|
||||
- Uses Bun APIs directly (`Bun.file`, `Bun.write`, `Bun.spawn`, `Bun.Glob`) — no fs-extra, no
|
||||
node shims. File tools read/write through `Bun.*`, not `fs`, where practical.
|
||||
- Path safety: every user/model-supplied path goes through `jail()` (in `src/ignore.ts`), which
|
||||
rejects escapes outside `process.cwd()`. Tools resolve paths against `process.cwd()`.
|
||||
- Error handling: tool `execute` functions return error text to the model or throw `Error` with a
|
||||
plain message — no error classes, no codes. Storage reads (`store.ts`, `memory.ts`) catch and
|
||||
degrade to empty rather than throw on corrupt JSON.
|
||||
- Tools are AI-SDK `tool()` objects with zod `inputSchema`. Any tool that mutates the workspace
|
||||
must be added to `MUTATING_TOOLS` in `src/tools.ts` — a test in `permission.test.ts` fails
|
||||
otherwise. The permission system (`src/permission.ts`) matches rules against the tool's subject
|
||||
(command for `bash`, path for file tools) with glob matching, and is pure/no-IO on purpose.
|
||||
- Comments explain *why*, often naming the failure being guarded against. Match that style.
|
||||
- Tests import from `bun:test`, build mock models with `MockLanguageModelV4` +
|
||||
`simulateReadableStream` from `ai/test`, and each test that touches the filesystem does
|
||||
`process.chdir()` into a fresh `mkdtemp` dir in `beforeEach` and restores in `afterEach`.
|
||||
|
||||
## Surprising / easy to break
|
||||
|
||||
- `bun test` runs the whole suite including `fallback-live.test.ts`, which spins up real local
|
||||
HTTP servers via `Bun.serve`, and `commit.test.ts`, which runs real `git` in temp repos — both
|
||||
need a working network stack and git on PATH.
|
||||
- Tool output is capped (`MAX_OUTPUT` in `src/tools.ts`); read_file returns NUL-sniffed binary
|
||||
files as an error. Don't remove these — they stop a model from burning its context.
|
||||
- Ink renders to the terminal, so library warnings are suppressed at the top of `cli.tsx`
|
||||
(`AI_SDK_LOG_WARNINGS = false`); anything written to stderr tears the UI.
|
||||
- Sessions, memory, and history live under `~/.shiro-neko/`, relocatable with `SHIRO_HOME`;
|
||||
tests depend on that env var to isolate state. Don't resolve the path eagerly at module load —
|
||||
`store.ts` resolves it per call for this reason.
|
||||
- Release tags must match `src/version.ts` exactly or `release.ts` stops the build.

# Audit
|
||||
|
||||
Checklist from a full audit of the codebase, run against `main` at `a22d8e1` ("release 0.1.0-beta.5").
|
||||
The greps cover every file under `src/`, `test/`, `docs/`, `.github/workflows/`, and `scripts/`.
|
||||
|
||||
Nothing here is a fix — it is a list. Items already tracked in `TODO.md` or `ROADMAP.md` say so;
|
||||
untracked items are marked **not yet tracked**.
|
||||
|
||||
---
|
||||
|
||||
## A. Clean findings (verified, no action needed)
|
||||
|
||||
- [x] **No TODO/FIXME/HACK markers in `src/`.** All 26 matches are false positives:
|
||||
placeholder attributes, the `TODO_MARK` export in `src/notebook.ts` (a literal string
|
||||
ingredient of the todos feature), and "later" in prose.
|
||||
- [x] **No `as any` / `@ts-ignore` / `@ts-expect-error` / `@ts-nocheck` / `: any` in `src/`.**
|
||||
Zero matches. The project's own `docs/development.md` rule is being kept.
|
||||
- [x] **No silently swallowed errors in `src/`.** Every `catch` was reviewed:
|
||||
- `src/registry.ts:116,155` — JSON parse failures become descriptive errors.
|
||||
- `src/registry.ts:120-123,159-162` — zod schema validation with named failure reasons.
|
||||
- `src/plugins.ts:59-63` — a throwing plugin hook fails **closed** (blocks the call).
|
||||
- `src/subagent.ts:233-237` — errors are reported and rethrown (never swallowed).
|
||||
- `src/tools.ts:80-82` — a batch read failure is reported in place, not thrown.
|
||||
- `src/headless.ts` serialization flattens `Error` before `JSON.stringify` (would emit `{}`).
|
||||
- `src/ui/App.tsx` — all 14 catch blocks surface the message in the UI.
|
||||
- `src/plugins-builtin.ts:213-215` — the only quiet `catch`, and it is deliberate,
|
||||
commented ("a missing binary is not worth interrupting the turn over").
|
||||
- [x] **No skipped tests.** No `.skip`, `xit`, or `xdescribe` in `test/` (one match was
|
||||
`process.exit(` containing "xit(").
|
||||
- [x] **Registry fetches are size-capped and schema-validated.** `src/registry.ts` caps
|
||||
content-length and body bytes (`fetchText`, lines 100-108), validates the index with
|
||||
`indexSchema` (line 120), and regex-validates every plugin manifest pattern (line 167).
|
||||
- [x] **Version/tag consistency is enforced twice.** `scripts/release.ts` refuses a build when
|
||||
the tag and `src/version.ts` disagree (line 129), and the release workflow asserts the
|
||||
built binary prints the expected version (`.github/workflows/release.yml:42-46`).
|
||||
- [x] **Install scripts match the build targets.** `test/ci.test.ts:85-101` iterates every
|
||||
`TARGETS` entry from `scripts/release.ts` and asserts the shell/PowerShell installers
|
||||
fetch exactly those asset names.
|
||||
- [x] **`.env`/`.pem` are refused on read;** the default permission table
|
||||
(`src/permission.ts:175-186`) matches the approvals banner in `README.md`. Unknown tools
|
||||
(MCP, plugins) default to `ask` rather than allow (line 235-236), so `mcp__*` needs no
|
||||
explicit rule.
|
||||
- [x] **`--yolo` cannot bypass the guard plugin.** Defaults fold `ask` into `allow` but never
|
||||
touch `deny` (`src/permission.ts:211-213`), and the guard refuses destructive commands
|
||||
in `beforeToolCall`, ahead of any approval.
|
||||
- [x] **Pinned toolchain.** Both workflows pin `bun-version: 1.3.14`, and `test/ci.test.ts:48-52`
|
||||
fails if the pin ever disagrees with the local `Bun.version`.
|
||||
- [x] **All three platforms in CI.** `ci.yml` runs the suite on ubuntu, macos, windows
|
||||
(required — the tools shell out to `rg`, git, and a platform shell).
|
||||
|
||||
---
|
||||
|
||||
## B. Bugs
|
||||
|
||||
- [ ] **`src/ui/App.tsx:613` — formatting glitch.** The `}` closing the `try` is jammed onto the
|
||||
same line as the preceding statement:
|
||||
`push({ kind: 'info', text: await hooks.summarizeMemory() }); } catch (e) {`
|
||||
Cosmetic only, but it is the kind of blemish left by an unformatted edit and reads as a
|
||||
slip. **not yet tracked**
|
||||
- [ ] **`.github/workflows/release.yml` — the `dry_run` input is dead.** `workflow_dispatch`
|
||||
declares `inputs.dry_run` (default `true`) but no step ever reads it. Nothing consults the
|
||||
value, so `dry_run=false` changes nothing, and because the `publish` job gates on
|
||||
`startsWith(github.ref, 'refs/tags/v')`, a manual run can never publish regardless of the
|
||||
input. Either wire the input into the `publish` `if`, or delete it and let the tag-only
|
||||
gate be the whole story. **not yet tracked**
|
||||
- [ ] **`README.md` says "Nineteen built-in tools" — it is now twenty.** `git_commit_message`
|
||||
(shipped in beta.5 via `src/commit.ts` + `cli.tsx:281`) is a built-in tool, and
|
||||
`TOOL_SETS.git` carries it (`src/tools-git.ts:189`). The count is one short;
|
||||
`docs/tools.md` already says "twenty" (line 63), so README is the stale one.
|
||||
**not yet tracked**
|
||||
|
||||
---
|
||||
|
||||
## C. Gaps / not implemented (official — tracked in TODO.md or ROADMAP.md)
|
||||
|
||||
### TODO.md "Now" — next up
|
||||
|
||||
- [ ] **Summarize the pruned span.** Compaction drops messages and tells the model nothing, so a
|
||||
decision from earlier in the session can be contradicted. (TODO.md `## Now`, first item)
|
||||
- [ ] **A spend ceiling.** `maxSpendUsd` in config, warn at 80%, refuse the next turn at 100%,
|
||||
headless exits non-zero naming the ceiling. Nothing stops a looping headless run today.
|
||||
(TODO.md `## Now`)
|
||||
- [ ] **A cheaper model for subagents.** `subagentModel` in config; an `explore` subagent is
|
||||
search, not reasoning, and today pays the parent's per-token rate. (TODO.md `## Now`)
|
||||
- [ ] **Hot-reload an installed entry.** `/registry add` writes the file and says restart; the
|
||||
skill catalogue and guard chain are assembled at boot. (TODO.md `## Now`)
|
||||
|
||||
### TODO.md "Next"
|
||||
|
||||
- [ ] **MCP without the schema tax.** Twenty MCP tools ≈ 2,750 tokens of schema per request;
|
||||
`toolSets` does not gate them. Plan: `mcp_list` / `mcp_inspect` / `mcp_call` meta-tools,
|
||||
prompt names servers not schemas. (TODO.md `## Next`; ROADMAP `## Next` + `## Later`)
|
||||
- [ ] **Custom commands from a file.** `.shiro/commands/*.md`, `$ARGUMENTS`, `$1`,
|
||||
`` !`cmd` `` shell substitution with the guard applied. (TODO.md `## Next`; ROADMAP `## Next`)
|
||||
- [ ] **Derive the tool-name lists.** `TOOL_SETS` and `MUTATING_TOOLS` are hand-maintained; a
|
||||
tool added to one and forgotten in the other is a silently ungated write. (TODO.md
|
||||
`## Next`; ROADMAP `## Next` "Derived tool metadata")
|
||||
- [ ] **Subagent parallelism.** Two independent searches run sequentially; the panel already
|
||||
renders several agents, the loop does not fan out. (TODO.md `## Next`; ROADMAP `## Later`)
|
||||
- [ ] **Undo a turn.** `/resume` restores a session but nothing walks one step back; `bash`
|
||||
effects cannot be snapshotted and the docs would say so. (TODO.md `## Next`; ROADMAP `## Next`)
|
||||
|
||||
### ROADMAP "Next" / "Later" — tracked, not yet scheduled in TODO.cpp-equivalent detail
|
||||
|
||||
- [ ] **Registry trust.** No signatures; `registryUrl` is the whole trust decision. Publisher
|
||||
keys + pinned digest per entry. (ROADMAP `## Next`; also TODO.md Known rough edges)
|
||||
- [ ] **Lossless-enough compaction** — same work as "Summarize the pruned span". (ROADMAP `## Next`)
|
||||
- [ ] **Session branching**, **structured diff review**, **plugin code from disk** (needs a
|
||||
sandbox story), **prompt caching** (stable prefix vs volatile suffix), **external hooks**
|
||||
(needs a trust story), **OS-level sandboxing** (Seatbelt/Landlock/Windows equivalent).
|
||||
(ROADMAP `## Later`)
|
||||
- [ ] **Deliberately declined** (do not "fix"): web UI, auto-commit, vector search, tool-call
|
||||
retries, client/server split, LSP integration — all recorded in ROADMAP `## Declined`.
|
||||
|
||||
---
|
||||
|
||||
## D. Documentation drift (untracked)
|
||||
|
||||
- [ ] **README tool count** — see Bug B.3. **not yet tracked**
|
||||
- [ ] **TODO.md "Done" is missing the rest of beta.5.** "Kept for one release, then deleted",
|
||||
but of the beta.5 batch (more tools incl. `git_branch`/`git_commit_message`/
|
||||
`move_file`/`delete_file`, the `protect` plugin, `security`/`perf`/`migrate` skills, the
|
||||
MCP panel wizard, the UI refinements, the farewell message) only "a dead provider item
|
||||
ends the turn" was checked off. Either the Done list gets the beta.5 items or it gets
|
||||
rotated, as the file's own rule says. **not yet tracked**
|
||||
- [ ] **`docs/registry.md` and `docs/headless.md`** are referenced by the README table and both
|
||||
exist — verified clean, no action.
|
||||
|
||||
---
|
||||
|
||||
## E. Test-coverage gaps
|
||||
|
||||
- [ ] **`src/cli.tsx` (562 lines) has no unit test.** Nothing in `test/` imports it. Its flag
|
||||
parsing (`-p`, `--json`, `--yolo`, `--resume`, provider setup, `/provider` wiring) is
|
||||
exercised only by hand or through `runHeadless` (`test/headless.test.ts`), which bypasses
|
||||
the argument surface. The largest module in `src/` outside the UI is the least tested one.
|
||||
**not yet tracked**
|
||||
- [ ] **`src/ui/Onboard.tsx` has no test.** The provider on-boarding wizard is never rendered in
|
||||
the suite. **not yet tracked**
|
||||
- [ ] **`src/ui/PromptInput.tsx` has no test** — the `@` completion input is only covered
|
||||
indirectly through `App`. (`src/complete.ts` itself is well tested.) **not yet tracked**
|
||||
- [ ] **`src/ui/panel-bodies.ts` and `src/ui/buses.ts` have no direct tests.**
|
||||
**not yet tracked**
|
||||
- [ ] **29 `as any` casts across 17 test files.** The identical mock `usage` object
|
||||
(`{ inputTokens: {...}, outputTokens: {...} } as any`) is copied verbatim in 7+ UI test
|
||||
files — a shared typed fixture in `test/helpers.ts` would remove the repetition and the
|
||||
casts in one move. Production `src/` remains clean; this is test-only debt. **not yet tracked**
|
||||
|
||||
---
|
||||
|
||||
## F. Maintenance debt
|
||||
|
||||
- [ ] **Pricing table is hand-entered with no source note or date** — `src/pricing.ts:8-22`.
|
||||
Rates drift; `estimateTokens` also divides JSON length by four (session.ts:90), which is
|
||||
fine as a compaction threshold but misleads in `/cost`. Both tracked in TODO.md
|
||||
`## Maintenance`.
|
||||
- [ ] **`listPaths` walks up to 5000 files once per session** — fine for a repo, wasteful in a
|
||||
monorepo, never notices a file created after the first `@`. Tracked in TODO.md.
|
||||
- [ ] **`MUTATING_TOOLS` (tools.ts:799-807) is only used by tests and docs.** The runtime gate
|
||||
is `DEFAULT_PERMISSIONS` + the unknown-tool `ask` default. Tracked in TODO.md — either
|
||||
delete it or make `DEFAULT_PERMISSIONS` derive from it.
|
||||
- [ ] **CI actions are about to leave Node 20.** The last release run annotated that actions on
|
||||
Node 20 are being forced onto Node 24. `actions/checkout@v4`, `setup-bun@v2`,
|
||||
`upload-artifact@v4`, `download-artifact@v4` still work, but the major-version bumps will
|
||||
become the silent fix; watch for the annotation to turn red. **not yet tracked**
|
||||
- [ ] **Oversized modules.** `src/ui/App.tsx` (863), `src/tools.ts` (717), `src/cli.tsx` (562),
|
||||
`src/session.ts` (500), `src/ui/Panels.tsx` (398). All of them grew past a comfortable
|
||||
review size during the beta.5 batch. Not a bug — a "who reads 863 lines" concern.
|
||||
**not yet tracked**
|
||||
|
||||
---
|
||||
|
||||
## G. Known rough edges (tracked in TODO.md, reproduced here for the record)
|
||||
|
||||
- [x] `/clear` wipes terminal scrollback (escape sequence takes earlier history with it).
|
||||
- [x] Memory has no conflict resolution; two contradictory notes both inject.
|
||||
- [x] Windows `cmd /c` vs `bash -lc` — the prompt names the platform, does not translate.
|
||||
- [x] An unknown name in `toolSets` is dropped silently — reads as "that set is off".
|
||||
- [x] Permission rules gate the call, not what it does — no OS sandbox around the shell.
|
||||
- [x] The reasoning panel is per-turn, not per-step.
|
||||
- [x] An interrupted command's effects are unknown, and the model is told so.
|
||||
- [x] `@` completion lists files, not directories.
|
||||
- [x] An installed skill is a stranger's words in the system prompt; nothing re-checks it later.
|
||||
- [x] A registry index is trusted for its contents, not its authorship.

# Changelog
|
||||
|
||||
All notable changes to this project are documented here. The format follows
|
||||
[Keep a Changelog](https://keepachangelog.com/en/1.1.0/) and the project adheres to
|
||||
[Semantic Versioning](https://semver.org/spec/v2.0.0.html).
|
||||
|
||||
## [1.0.0]
|
||||
|
||||
The first stable release. Cost control, a larger tool and skill surface, custom slash
|
||||
commands, auto-loaded extensions, and a redesigned welcome interface, on top of the beta
|
||||
line's agent loop, approval model, and safety guarantees.
|
||||
|
||||
### Added
|
||||
|
||||
- **Spend ceiling** ("maxSpendUsd" in config). Checked before each turn: past the limit the
|
||||
model is never called, the turn is refused naming the ceiling, headless exits non-zero,
|
||||
and it warns once at 80% of the limit. Unpriced models cannot be measured, so the ceiling
|
||||
does not apply to them.
|
||||
- **Cheaper subagent model** ("subagentModel" in config). "explore" subagents — search, not
|
||||
reasoning — resolve against a configured cheaper model while "review" and "worker" keep the
|
||||
parent's. "/cost" reports subagent spend separately, priced against the subagent's model id.
|
||||
- **Twenty new built-in tools** (41 total) in a new "extra" tool set, across four families:
|
||||
- line edits: insert_lines, delete_lines, replace_lines, append_file, prepend_file, count_lines
|
||||
- filesystem: tree, file_info, find_files, recent_files, changed_files
|
||||
- git (read-only, argv-spawned): git_log_file, git_diff_commits, git_show_file, git_current_branch, git_changed_in_ref
|
||||
- code and environment: find_symbol, json_query, outline, read_symbol, env_info, count_tokens
|
||||
- **Twenty new bundled skills** (29 total), including plan, docs, api-design, ci-cd, db,
|
||||
docker, frontend, git-workflow, logging, optimize-sql, release, accessibility, data, i18n,
|
||||
deps, onboarding, ux-copy, readme, incident, perf-frontend.
|
||||
- **Ten new plugins**, all data. Safety refusals on by default — no-force-push, no-net-pipe,
|
||||
no-root, no-env-write — and opt-in workflow plugins — no-main-commit, no-git-config,
|
||||
confirm-delete, conventional-commit, tests-first, small-diffs.
|
||||
- **Custom slash commands** from Markdown files in ".shiro/commands/" and
|
||||
"~/.shiro-neko/commands/", with frontmatter "description"/"agent", "$ARGUMENTS" and
|
||||
positional "$1", and shell substitution passed through the guard. A custom command can
|
||||
never shadow a built-in.
|
||||
- **Auto-loaded external extensions** from "~/.shiro-neko/{skills,tools,plugins}" and
|
||||
".shiro/{skills,tools,plugins}". All data, never code: tools are bounded manifests (a shell
|
||||
template through the guard, an HTTPS fetch, or a workspace read), plugins are refusal
|
||||
manifests. Malformed files are reported and skipped, never fatal.
|
||||
|
||||
### Changed
|
||||
|
||||
- **Skills now live as Markdown files** in "src/skills-md/", embedded into the compiled binary
|
||||
by Bun text imports, replacing the previous TypeScript string constants. A format test
|
||||
enforces that each parses with valid frontmatter and a real body. The eleven pre-existing
|
||||
skills were also deepened.
|
||||
- **Welcome interface redesigned** into a structured dashboard: a session banner, a grouped
|
||||
environment panel with attention-worthy facts coloured out of the quiet layer, and a meta
|
||||
bar. The prompt input sits in a two-tone box with the agent and model row inside it and a
|
||||
split footer beneath.
|
||||
- **System prompt advanced** with a discrete failure-recovery loop, a delegation policy, and
|
||||
compaction awareness.
|
||||
|
||||
### Fixed
|
||||
|
||||
- **Release workflow "dry_run" input is now honoured.** A manual dispatch publishes only when
|
||||
it is unchecked; tag pushes always publish. Previously the input was declared but never read,
|
||||
so a manual run could never publish regardless of its value.
|
||||
- **Documentation drift** corrected across the tool count, the bundled-skill count, the plugin
|
||||
defaults, and the README quickstart.
|
||||
|
||||
## [0.1.0-beta.5]
|
||||
|
||||
- A dead provider item no longer ends the turn: a 404 naming a missing item rewrites the
|
||||
history inline and retries once.
|
||||
- More tools (git_commit_message, git_branch, move_file, delete_file), the "protect" plugin,
|
||||
the security/perf/migrate skills, the "/mcp add" wizard, and the farewell message.
|
||||
|
||||
## [0.1.0-beta.4]
|
||||
|
||||
- Compaction no longer stops the loop, and is bounded to keep the widest recent tool tail.
|
||||
- The external registry for skills and plugins.
|
||||
- Permission rules matched per command and path, replacing the per-tool list.
|
||||
- apply_patch, web_fetch, and writable worker subagents.
|
||||
|
||||
## [0.1.0-beta.3]
|
||||
|
||||
- Fourteen built-in tools with gateable tool sets.
|
||||
- Streaming reasoning display, the mid-turn prompt queue, multi_edit, list_dir, read-only git
|
||||
tools, batch reads, @file completion, and interruptible commands.
|
||||
|
||||
## [0.1.0-beta.1]
|
||||
|
||||
- The core agent loop with SDK-enforced tool approvals, endpoint fallback, and retries.
|
||||
- The initial tool set, Ink interface, agent variants, skills, plugins, per-project memory,
|
||||
session persistence, subagents, MCP, and five-platform builds.

### 0.1.0-beta.5
|
||||
|
||||
**A dead provider item no longer ends the turn.** An `item_reference` resolves only while the
|
||||
provider still stores that item, so a resumed session — or one that fell back to `/v1/responses`
|
||||
mid-turn — could fail with 404 "Item with id 'msg_...' not found" on every attempt, since every
|
||||
retry sent the same reference. Compaction now strips every provider `itemId` from what it sends,
|
||||
and a 404 naming a missing item rewrites the session's history inline and runs the request again,
|
||||
once per turn and only before any output has been delivered.
|
||||
|
||||
**Interface.** Context shows the elapsed working time and a compaction warning as the threshold
|
||||
approaches, diff lines are numbered, markdown task lists render, the prompt edits by word and
|
||||
`ctrl-d` deletes to the end of line, and a farewell tells you how to resume the session.
|
||||
|
||||
**More tools.** `git_commit_message` writes a commit message from the staged diff and the
|
||||
repository's own recent subjects, in one nested model call — it never commits, so it needs no
|
||||
approval. `move_file` and `delete_file` fill the gap that made every rename a write-then-delete
|
||||
pair: both are gated, `move_file` matches permission rules at both ends, and `delete_file`
|
||||
refuses a directory because removing a tree is what the guard blocks in `bash`. `git_branch`
|
||||
lists branches with the current one marked.
|
||||
|
||||
**More plugins.** `protect` refuses writes to `.git`, lockfiles, `node_modules`, vendored code,
|
||||
and build output — files a tool owns rather than a person, where an edit leaves a repository
|
||||
that looks fine and behaves wrongly. It ships on, alongside `guard` and `secrets`, and every
|
||||
path-based guard now shares one helper that understands where each write tool keeps its paths.
|
||||
|
||||
**More skills.** `security` (trust boundaries, then injection, authorisation, traversal, SSRF),
|
||||
`perf` (measure, locate, one change, stop at a target), and `migrate` (changelog first, every
|
||||
call site before one edit, never hand-merge a lockfile) join the bundled set.
|
||||
|
||||
**The MCP panel.** `/mcp add` walks through a local or remote server — kind, name, command and
|
||||
arguments or URL and headers — validating the name against the `mcp__<server>__<tool>`
|
||||
namespace as it is typed rather than failing at connect. `/mcp` lists what is configured with
|
||||
each server's live tool count or its connection error, and `/mcp remove` takes one out. All
|
||||
three write `config.json` directly; a new server connects on the next start, because
|
||||
connecting mid-turn would change the tool list under a running request.
|
||||
|
||||
### 1.0.0
|
||||
|
||||
The first stable release. The beta line's architecture held; this release rounds out cost
|
||||
control, extensibility, and the interface, and hardens the test suite to match.
|
||||
|
||||
**Cost control.** Two halves of one problem, both shipped. A **spend ceiling** (`maxSpendUsd`)
|
||||
checks before each turn: past the limit the model is never called, the turn is refused naming
|
||||
the ceiling, headless exits non-zero, and it warns once at 80%. A **cheaper subagent model**
|
||||
(`subagentModel`) runs `explore` — which is search, not reasoning — on a less expensive model
|
||||
while `review` and `worker` keep the parent's; `/cost` reports subagent spend as its own line,
|
||||
priced against the subagent's model id.
|
||||
|
||||
**Tools: 41 built-in.** Twenty new tools in four families, all path-jailed and ignore-aware,
|
||||
in a new `extra` tool set: precise line edits (`insert_lines`, `delete_lines`, `replace_lines`,
|
||||
`append_file`, `prepend_file`, `count_lines`), filesystem navigation (`tree`, `file_info`,
|
||||
`find_files`, `recent_files`, `changed_files`), read-only git extensions (`git_log_file`,
|
||||
`git_diff_commits`, `git_show_file`, `git_current_branch`, `git_changed_in_ref`), and code and
|
||||
environment reads (`find_symbol`, `json_query`, `outline`, `read_symbol`, `env_info`,
|
||||
`count_tokens`). Every git call still spawns the binary with a fixed argv, never a shell.
|
||||
|
||||
**Skills: 29 bundled, as Markdown.** The catalogue grew from nine to twenty-nine and every
|
||||
skill moved to a single source of truth: a Markdown file in `src/skills-md/`, frontmatter and
|
||||
body, embedded into the compiled binary by Bun text imports. A format test enforces that each
|
||||
one parses and carries a real body.
|
||||
|
||||
**Plugins: 10 more, all data.** Six narrow safety refusals (force push, pipe-to-shell, root
|
||||
elevation, env credential writes, main-branch commits, git config changes) and three advisory
|
||||
plugins (conventional commits, tests-first, small diffs) plus a delete guard for ambiguous
|
||||
paths. The safety refusals are on by default for the same reason the guard is; the opinionated
|
||||
ones are opt-in.
|
||||
|
||||
**Custom slash commands.** A Markdown file in `.shiro/commands/` or `~/.shiro-neko/commands/`
|
||||
becomes a slash command, with frontmatter `description`/`agent`, `$ARGUMENTS` and `$1`
|
||||
positionals, and `` !`cmd` `` substitution passed through the guard. A custom command can never
|
||||
shadow a built-in.
|
||||
|
||||
**Auto-loaded extensions.** External skills, tools, and plugins load from
|
||||
`~/.shiro-neko/<kind>/` and `.shiro/<kind>/` — all data, never code. An external tool is a
|
||||
bounded manifest (a shell template through the guard, an HTTPS fetch, or a workspace file
|
||||
read); an external plugin is a refusal manifest. A malformed file is reported and skipped,
|
||||
never fatal.
|
||||
|
||||
**Interface.** The welcome screen is a structured dashboard — a session banner, a grouped
|
||||
environment panel with attention-worthy facts lifted out of the quiet layer, and a meta bar —
|
||||
replacing a wall of dim text. The input sits in an OpenCode-style two-tone box with the
|
||||
agent·model row inside it and a split footer beneath.

tree: killing `cmd /c` alone left the real command holding both pipes open, so the

interrupt appeared to do nothing for 19 seconds
|
||||
- [x] **Compaction no longer stops the loop.** Pruning used to drop any assistant part whose
|

reasoning item it removed, which on a reasoning model is every tool call. The model lost
|

its record of what it had run and re-ran it until the step limit. The repair strips the

shown in full before install; plugins are a validated manifest of deny rules, never code
|
||||
- [x] Context shown as a percentage of the compaction threshold, amber at two thirds, red at 90
|
||||
- [x] **Permission rules per command and path**, replacing the per-tool list. `bash` was one
|
||||
yes/no for `git status` and `rm -rf`, so pressing `a` once removed the gate for both.
|
||||
Rules match the call's subject, `always` grants a pattern rather than the tool, `.env` and
|
||||
`.pem` are refused on read, and an identical call repeated three times in a turn asks even
|

- [x] **`web_fetch`**, size-capped HTTP(S) to markdown in the opt-in `net` tool set, with

redirect and private-address checks

ceiling, warns once at 80%, headless exits non-zero. Unpriced models are not enforced
|
||||
- [x] A cheaper subagent model (`subagentModel`): `explore` resolves against it, `review` and

`worker` keep the parent's, `/cost` splits subagent spend by model id

# Custom slash commands
|
||||
|
||||
A Markdown file becomes a slash command. Write the prompt once, run it with `/name` any time.
|
||||
|
||||
Two directories are scanned, the project shadowing the user by name:
|
||||
|
||||
| Origin | Directory |
|
||||
|---|---|
|
||||
| user | `~/.shiro-neko/commands/*.md` |
|
||||
| project | `.shiro/commands/*.md` |
|
||||
|
||||
The filename is the command: `.shiro/commands/review-diff.md` becomes `/review-diff`. Names are
|
||||
letters, digits, dashes, and underscores; anything else is skipped. A custom command can never
|
||||
shadow a built-in — `/cost` always runs the built-in `/cost`.
|
||||
|
||||
## Format
|
||||
|
||||
```markdown
|
||||
---
|
||||
description: Review the staged diff for defects
|
||||
agent: review
|
||||
---
|
||||
|
||||
Review the staged changes. For each finding give file, line, what breaks, and the fix.
|
||||
```
|
||||
|
||||
Frontmatter is optional but useful:
|
||||
|
||||
- **`description`** — the one line shown in the `/` menu. Without it the first body line is used.
|
||||
- **`agent`** — run this command under a specific agent variant (`default`, `quick`, `deep`,
|
||||
`plan`, `review`). The variant is restored afterwards, so one command does not leak its agent
|
||||
into the rest of the session.
|
||||
|
||||
Everything after the frontmatter fence is the prompt. A file with an empty body is skipped, as
|
||||
is one that fails to parse.
|
||||
|
||||
## Arguments
|
||||
|
||||
The body is a template, expanded against whatever you type after the command:
|
||||
|
||||
- `$ARGUMENTS` — the whole argument string.
|
||||
- `$1`, `$2`, … — positional arguments. A missing positional expands to nothing.
|
||||
|
||||
```markdown
|
||||
Compare $1 against $2 and report the differences. Context: $ARGUMENTS
|
||||
```
|
||||
|
||||
`/compare src/a.ts src/b.ts` sends `Compare src/a.ts against src/b.ts … Context: src/a.ts src/b.ts`.
|
||||
|
||||
## Shell substitution
|
||||
|
||||
A `` !`command` `` inline runs the shell command and inlines its output before the prompt is
|
||||
sent:
|
||||
|
||||
```markdown
|
||||
Review this diff:
|
||||
|
||||
!`git diff --staged`
|
||||
```
|
||||
|
||||
Every substitution runs through the **guard** before executing, exactly as a direct `bash` call
|
||||
is — so a custom command cannot smuggle a destructive command past you. A substitution that
|
||||
exits non-zero, or one the guard refuses, fails the command with the reason named.
|
||||
|
||||
## When to write one
|
||||
|
||||
- A prompt you find yourself retyping: a review shape, a release checklist, a project-specific
|
||||
"how we test".
|
||||
- A prompt that should pin an agent: a read-only review command that always runs under `review`.
|
||||
- Project conventions the whole team should share: commit `.shiro/commands/` so everyone gets
|
||||
the same commands.
|
||||
|
||||
For behaviour that must survive across sessions rather than be invoked on demand, use
|
||||
[memory](memory.md). For instructions the agent loads by task rather than by name, use a
|
||||
[skill](skills.md). For extensions that add tools or refusal rules rather than prompts, see
|
||||
[extensions](extensions.md).

# Extensions: auto-loaded skills, tools, and plugins
|
||||
|
||||
External extensions load automatically from two directories on every start, the project
|
||||
shadowing the user by name:
|
||||
|
||||
| Origin | Directories |
|
||||
|---|---|
|
||||
| user | `~/.shiro-neko/skills` `~/.shiro-neko/tools` `~/.shiro-neko/plugins` |
|
||||
| project | `.shiro/skills` `.shiro/tools` `.shiro/plugins` |
|
||||
|
||||
Drop a file in and it is live on the next start. No registry, no install command, no restart
|
||||
of anything but the CLI itself.
|
||||
|
||||
**Everything here is data, never code.** That is the same rule the [registry](registry.md)
|
||||
enforces, and it is the whole security model. An external extension can add instructions, a
|
||||
bounded tool, or a refusal rule — it cannot run arbitrary code, so it cannot read every file
|
||||
the agent can read or lie about what it blocks. A malformed file is reported on the welcome
|
||||
dashboard and skipped, never fatal.
|
||||
|
||||
## Skills
|
||||
|
||||
A skill is a Markdown file with frontmatter, exactly like a bundled one:
|
||||
|
||||
```markdown
|
||||
---
|
||||
name: deploy
|
||||
description: Ship a release. Use when asked to deploy or cut a release.
|
||||
---
|
||||
|
||||
# Deploy
|
||||
|
||||
1. Confirm the tests pass. Do not deploy on a red suite.
|
||||
2. Tag with the version from src/version.ts, not by hand.
|
||||
```
|
||||
|
||||
Skills merge by name with the precedence `builtin < registry < user < project`, so your own
|
||||
`debug.md` overrides the bundled `debug`. See [skills](skills.md) for the full format.
|
||||
|
||||
## Tools
|
||||
|
||||
A tool is a JSON manifest describing one bounded operation. Three kinds, each with a ceiling
|
||||
on what it can do:
|
||||
|
||||
```json
|
||||
{
|
||||
"name": "recent-changes",
|
||||
"description": "List the ten most recently changed files",
|
||||
"kind": "shell",
|
||||
"command": "git diff --name-only HEAD~10",
|
||||
"autoApprove": true
|
||||
}
|
||||
```
|
||||
|
||||
| Field | Meaning |
|
||||
|---|---|
|
||||
| `name` | The tool name the model calls. Letters, digits, dashes, underscores. |
|
||||
| `description` | What the model reads to decide when to use it. |
|
||||
| `kind` | `shell`, `http`, or `read`. |
|
||||
| `command` | For `shell`: the template to run, with an optional `{arg}` placeholder. |
|
||||
| `url` | For `http`: the URL to fetch, with an optional `{arg}` placeholder. HTTPS only. |
|
||||
| `path` | For `read`: the workspace file to return, with an optional `{arg}` placeholder. |
|
||||
| `autoApprove` | `false` to require approval before running. Default `true`. |
|
||||
|
||||
The model passes a single optional `arg` string, substituted into `{arg}`.
|
||||
|
||||
**The limits are the point.** A `shell` tool runs a fixed template through the **guard** and
|
||||
the platform shell — the same chain a built-in `bash` call goes through, so an installed tool
|
||||
cannot do what the agent itself may not. An `http` tool fetches one HTTPS URL. A `read` tool
|
||||
returns one workspace file, jailed to the workspace. None of them executes code from the
|
||||
manifest.
|
||||
|
||||
## Plugins
|
||||
|
||||
A plugin is a refusal manifest — the same shape the registry installs — a name, an optional
|
||||
prompt appendix, and deny rules matched against tool input:
|
||||
|
||||
```json
|
||||
{
|
||||
"name": "no-prod-config",
|
||||
"description": "refuses to edit production config",
|
||||
"appendix": "Production config is changed by hand, never by the agent.",
|
||||
"deny": [
|
||||
{ "tools": ["write_file", "edit_file"], "pathPattern": "config/production", "reason": "production config is hand-edited" },
|
||||
{ "tools": ["bash"], "commandPattern": "kubectl\\s+apply", "reason": "deploys to the cluster" }
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
A rule names the tools it covers and either a `pathPattern` (matched against the path a file
|
||||
tool carries) or a `commandPattern` (matched against a `bash` command), both as case-insensitive
|
||||
regexes, plus the `reason` handed to the model when it blocks. Patterns are validated on load;
|
||||
an invalid regex is a reported error, not a crash.
|

Refusal plugins compose with the built-in [plugins](plugins.md) — the first block wins.

## Relationship to the registry
|
||||
|
||||
The [registry](registry.md) fetches the same kinds of files over HTTPS with a confirmation
|
||||
step. Auto-load is for your own and your project's files, which need no confirmation because
|
||||
you wrote them. The two mechanisms share the loaders and the safety model; they differ only in
|
||||
where the file comes from.

# MCP
|

|

Model Context Protocol servers contribute tools to the agent. Two transports: a local
|
||||
command over stdio, and a remote http or sse endpoint.
|
||||
|
||||
## Adding one from the prompt
|
||||
|
||||
```
|
||||
/mcp list what is configured, with the tool count each contributed
|
||||
/mcp add wizard: local or remote, then the fields that kind needs
|
||||
/mcp remove <name>
|
||||
```
|
||||
|
||||
`/mcp add` asks for the kind first, because the two need different fields — a command and
|
||||
its arguments against a URL and its headers — and a single form with half of it inapplicable
|
||||
is worse than two short ones.
|
||||
|
||||
```
|
||||
Add an MCP server
|
||||
none configured yet
|
||||
> local a command on this machine, over stdio
|
||||
remote an http or sse endpoint
|
||||
```
|
||||
|
||||
The name is validated as it is typed. Tools register as `mcp__<server>__<tool>`, so a name
|
||||
with a space or a double underscore produces a tool the model cannot address and two servers
|
||||
whose namespaces can collide — both are refused in place rather than at connect time. A name
|
||||
already in the config is refused too.
|
||||
|
||||
For a local server the wizard then asks for the command and its arguments; arguments split on
|
||||
spaces and keep quoted runs together, so `--root "/home/my folder"` arrives as one argument.
|
||||
For a remote one it asks for the URL — http or https only — and optional headers as
|
||||
`KEY: value, OTHER: value`.
|
||||
|
||||
Both write straight to `config.json` and merge with whatever is already there. **A new server
|
||||
connects on the next start**, not mid-session: connecting during a turn would change the tool
|
||||
list under a request that is already running.
|
||||

||||

|

does not know about is still interruptible by hand — see [tools](tools.md#bash).
|
||||
|
||||
### `protect` (default on)
|
||||
|
||||
Refuses writes to files whose contents belong to a tool rather than to anyone editing them by
|
||||
hand. This is a different failure from a secret: the repository looks fine and behaves wrongly,
|
||||
and the breakage surfaces somewhere else entirely.
|
||||
|
||||
| Refused | Why |
|
||||
|---|---|
|
||||
| `.git/**` | git's own object store |
|
||||
| `bun.lock`, `package-lock.json`, `pnpm-lock.yaml`, `yarn.lock`, `Cargo.lock`, `go.sum`, `poetry.lock`, `uv.lock`, `composer.lock`, `Gemfile.lock` | the package manager owns it |
|
||||
| `node_modules/**` | an installed dependency |
|
||||
| `vendor/**`, `target/debug/**`, `target/release/**` | vendored or build directory |
|
||||
| `dist/**`, `build/**`, `out/**`, `.next/**`, `.nuxt/**`, `.svelte-kit/**`, `coverage/**` | generated output |
|
||||
| `.venv/**`, `.tox/**`, `.mypy_cache/**`, `.ruff_cache/**`, `.turbo/**` | tool caches |
|
||||
|
||||
```
|
||||
refusing to write bun.lock (a lockfile the package manager owns). Regenerate it with the
|
||||
tool that owns it rather than editing it.
|
||||
```
|
||||
|
||||
The message says what to do instead, which matters: a model told only "no" writes the same
|
||||
content somewhere else. A lockfile is regenerated by `bun install`; build output is regenerated
|
||||
by the build.
|
||||
|
||||
Both separators match, so `node_modules\react\index.js` is refused on Windows too. Lookalike
|
||||
names are not: `src/gitignore-parser.ts`, `docs/dist-layout.md`, and `distributed/queue.ts` all
|
||||
write normally.
|
||||
|
||||
### `time` (default on)
|
||||
|
||||
Adds `current_time`, returning ISO 8601 plus the local string. Auto-approved; it reads
|
||||
nothing. Useful because models are confidently wrong about the date.
|
||||
|
||||
### The narrow safety refusals (default on)
|
||||
|
||||
Six small plugins, each blocking one irreversible class of mistake. They are on by default for
|
||||
the same reason the guard is: a safety check you have to opt into is not one. Each is data — a
|
||||
name, a pattern list, and a refusal message — matched against the `bash` command string (or, for
|
||||
`confirm-delete`, the path a `delete_file` carries).
|
||||
|
||||
| Plugin | Refuses | Why |
|
||||
|---|---|---|
|
||||
| `no-force-push` | `git push --force`, `--force-with-lease`, `-f`, `+<ref>` | rewrites remote history |
|
||||
| `no-net-pipe` | `curl … \| sh`, `wget … \| node`, `iex (iwr …)` | executes a download unseen |
|
||||
| `no-root` | `sudo …`, elevated `runas` / `Start-Process -Verb RunAs` | nothing the agent does should need root |
|
||||
| `no-env-write` | `export …KEY/TOKEN/SECRET/PASSWORD=…` | writes a credential into the environment |
|
||||
| `no-main-commit` | `git commit`/`git merge` naming `main`/`master` | touches the default branch directly |
|
||||
| `no-git-config` | `git config --global`, identity/runner keys | changes how git identifies or runs |
|
||||
|
||||
Normal commands pass: `git push origin feature`, `npm test`, `export NODE_ENV=production`. The
|
||||
patterns target the irreversible act, not the command family.
|
||||
|
||||
### The advisory plugins (opt in)
|
||||
|
||||
Three plugins carry only a prompt appendix — no blocking hook — so they shape behaviour without
|
||||
ever refusing a call. Enable them in config when you want the nudge:
|
||||
|
||||
| Plugin | Advises |
|
||||
|---|---|
|
||||
| `conventional-commit` | commit subjects as `type(scope): summary`, e.g. `fix(auth): reject expired tokens` |
|
||||
| `tests-first` | for a bug, pin it with a failing test before fixing; watch it fail, then pass |
|
||||
| `small-diffs` | one change does one thing; split a diff that is really two |
|
||||
|
||||
```json
|
||||
{ "plugins": ["guard", "secrets", "protect", "time", "conventional-commit", "small-diffs"] }
|
||||
```
|
||||
|
||||
### `confirm-delete` (opt in)
|
||||
|
||||
Refuses `delete_file` calls whose path is broad or ambiguous — a wildcard, a trailing slash, or
|
||||
an empty path — so a delete is always one explicit file:
|
||||
|
||||
```
|
||||
refusing to delete "src/*" (ambiguous or broad). Delete one explicit file.
|
||||
```
|
||||
|
||||
### `bell` (opt in)
|
||||
|
||||
Writes `\u0007` to stderr when a turn ends. Off by default — a bell after every turn is
|
||||
intrusive, but it is genuinely useful when a turn takes minutes.

||||
|
||||
Precise edits by line number, for changes that need no full-file rewrite and no exact-string
|
||||
match. All refuse a path outside the workspace.
|
||||
|
||||
| Tool | Does |
|
||||
|---|---|
|
||||
| `insert_lines` | Insert a block before a 1-based line, pushing the rest down. One past the end appends. |
|
||||
| `delete_lines` | Delete an inclusive line range. Refuses the whole file — that is `delete_file`'s job. |
|
||||
| `replace_lines` | Replace an inclusive line range with new text in one write. |
|
||||
| `append_file` | Add text to the end of a file. |
|
||||
| `prepend_file` | Add text to the top of a file, e.g. a header or import block. |
|
||||
| `count_lines` | Line count for one file, or per file across a glob. A size read before opening something large. |
|
||||
|
||||
### Filesystem
|
||||
|
||||
| Tool | Does |
|
||||
|---|---|
|
||||
| `tree` | Indented directory tree, ignore-aware, directories first. A broad shape faster to scan than `list_dir`. |
|
||||
| `file_info` | Size, line count, modified time, text-or-binary for one file. |
|
||||
| `find_files` | Files whose *name* contains a substring (not a glob), e.g. `auth`. |
|
||||
| `recent_files` | Files modified most recently, newest first. Find what a tool just touched. |
|
||||
| `changed_files` | The working-tree delta git reports (modified, staged, untracked). |
|
||||
|
||||
### Git extensions (read-only)
|
||||
|
||||
Spawned with a fixed argv, so they are auto-approved like the core git tools.
|
||||
|
||||
| Tool | Does |
|
||||
|---|---|
|
||||
| `git_log_file` | Commits that touched one file, newest first, with hash, date, subject. |
|
||||
| `git_diff_commits` | Diff between two refs, optionally limited to one path. |
|
||||
| `git_show_file` | A file's contents at a ref, e.g. `auth.ts` at `HEAD~3`. |
|
||||
| `git_current_branch` | The current branch with its upstream and ahead/behind count. |
|
||||
| `git_changed_in_ref` | Files changed between a ref and the working tree, names only. |
|
||||
|
||||
### Code and environment
|
||||
|
||||
| Tool | Does |
|
||||
|---|---|
|
||||
| `find_symbol` | Where a function, class, or type is *defined* across JS/TS, Python, Go, Rust. Matches declarations, not uses. |
|
||||
| `json_query` | One value from a JSON file by dotted path (`scripts.build`), instead of reading it whole. |
|
||||
| `outline` | Top-level declarations of a source file as a structural map. Read before opening a large file. |
|
||||
| `read_symbol` | The full body of one top-level definition by name. |
|
||||
| `env_info` | Platform, shell, and which runtimes and package managers are installed, before writing a command. |
|
||||
| `count_tokens` | Estimate the token cost of a file or string (~4 chars per token) before sending it to the model. |
|
||||

||||

from existing file path

```

Renames or relocates one file, creating the target directory. Refuses a missing source and an

occupied target, so a rename cannot silently overwrite work. Permission rules match **both**

|
||||
there.
|
||||
|

For a rename plus its callers in one atomic step, `apply_patch` is the better tool: it lands
|

Deletes one file and reports its size. A directory is refused: removing a tree is exactly what

### `git_commit_message`
|
||||
|
||||
Generates one commit message from the staged changes. The nested model call sees two

things: the staged diff, and the fifteen most recent commit subjects, because a message
|
||||
that ignores the repository's established style reads as foreign however accurate it is.
|
||||
An oversized diff is truncated before it reaches the model.
|
||||
|
||||
It never commits — it returns the message only, approval-free, because generating text
|
||||
cannot mutate anything. Running the commit stays on the gated `bash` path, where the

user sees the message and the command together.

|
||||
# Debugging
|
||||
|
||||
Do not guess. A guess that happens to work leaves the real cause in place.
|
||||
|
||||
## Reproduce first
|
||||
|
||||
Find the smallest command that shows the failure and record it with \`remember\`. If you
|
||||
cannot reproduce it, say so and ask what the user did differently — do not proceed on a
|
||||
hypothesis you cannot test.
|
||||
|
||||
## Three hypotheses, then evidence
|
||||
|
||||
Write down at least three causes that would produce this exact symptom. Rank them by how
|
||||
cheap they are to disprove, then disprove them in that order. State which one you are
|
||||
testing before you test it.
|
||||
|
||||
Evidence means observed output: a log line, a failing assertion, a value printed at the
|
||||
point of failure. "It should be X" is not evidence.
|
||||
|
||||
## Bisect when the space is large
|
||||
|
||||
- Recent regression: check what changed last.
|
||||
- Unclear layer: assert the value at each boundary until one is wrong.
|
||||
- Intermittent: run it in a loop and capture the failing case, do not reason about it abstractly.
|
||||
|
||||
## Fix the cause
|
||||
|
||||
Once you know the cause, fix that and nothing else. Do not tidy surrounding code in the
|
||||
same change — a bugfix diff should contain only the bug.
|
||||
|
||||
Write a test that fails before the fix and passes after. If you cannot express the bug as
|
||||
a test, say why.
|
||||
|
||||
## After two failed attempts
|
||||
|
||||
Stop. Re-read the error text literally, character by character. Check your assumption
|
||||
about which code is actually running: the wrong file, a stale build, a shadowed import,
|
||||
or a cached dependency accounts for most "impossible" bugs.

# Code review
|
||||
|
||||
Severity order. Do not lead with style.
|
||||
|
||||
1. **Incorrect behaviour** — wrong result, wrong edge case, wrong state after failure.
|
||||
2. **Missing validation at trust boundaries** — user input, network responses, file contents,
|
||||
anything crossing a process line. Internal calls need no defensive checks.
|
||||
3. **Security** — injection, path traversal, secrets in logs or errors, missing authz.
|
||||
4. **Resource handling** — unclosed handles, unbounded growth, unawaited promises.
|
||||
5. **Clarity** — only when it will cause a future defect.
|
||||
|
||||
## For each finding
|
||||
|
||||
State file and line, what breaks, and the change. Show the fix as code when it is short.
|
||||
|
||||
Skip anything a formatter would fix. Skip preference. If a choice is defensible, leave it.
|
||||
|
||||
## Say when it is fine
|
||||
|
||||
A review that invents problems to look thorough is worse than a short one. If the change
|
||||
is correct, say so and stop.
|
||||
|
||||
## Verify, do not assume
|
||||
|
||||
Read the surrounding code before calling something a bug. A "missing" null check often
|
||||
exists one level up. Run the tests if that is what settles it.

# Refactoring
|
||||
|
||||
Behaviour must not change. That is the whole constraint.
|
||||
|
||||
## Establish the safety net first
|
||||
|
||||
Run the existing tests and record that they pass. If the code has no tests, write one that
|
||||
pins current behaviour — including the ugly parts — before touching anything. Refactoring
|
||||
untested code is rewriting it.
|
||||
|
||||
## Then move in small steps
|
||||
|
||||
One transformation at a time, tests green between each. Rename, then extract, then move —
|
||||
not all three in one edit. A large refactor that fails leaves you unable to tell which step
|
||||
broke it.
|
||||
|
||||
## What not to do
|
||||
|
||||
- Do not fix bugs while refactoring. Note them, finish, fix separately.
|
||||
- Do not add abstraction for a single caller. Duplication beats a premature interface.
|
||||
- Do not widen the scope. The request was this code, not its neighbours.
|
||||
- Do not change public API unless asked; if it must change, say so first.
|
||||
|
||||
## Done means
|
||||
|
||||
Tests pass, behaviour is identical, and the diff is smaller than the reader feared.

# Testing
|
||||
|
||||
A test earns its place by failing when the code is wrong.
|
||||
|
||||
## Match the project
|
||||
|
||||
Read two existing test files first. Use their runner, their assertion style, their file
|
||||
layout, their naming. A test that looks foreign is a test nobody maintains.
|
||||
|
||||
## Test behaviour, not implementation
|
||||
|
||||
Assert on what a caller observes. A test that reaches into private state breaks on every
|
||||
refactor and catches nothing.
|
||||
|
||||
Cover: the normal case, the boundaries, and the failure. Failure cases catch more real
|
||||
defects than happy paths.
|
||||
|
||||
## Never do this
|
||||
|
||||
- Do not assert what the code currently returns without knowing it is correct — that pins
|
||||
the bug.
|
||||
- Do not weaken an assertion to make a test pass. If it fails, either the code or the
|
||||
expectation is wrong; find out which.
|
||||
- Do not delete a failing test. It is telling you something.
|
||||
|
||||
## Flaky tests
|
||||
|
||||
A test that passes alone and fails in a suite is a shared-state problem: a global, a
|
||||
temp directory, a port, an unawaited promise, or ordering. Find which, do not add a retry.
|
||||
|
||||
## Verify
|
||||
|
||||
Run the test and watch it fail before the fix, pass after. A test you never saw fail is
|
||||
not known to work.

# Verification
|
||||
|
||||
A green test suite says the tests pass. It does not say the feature works.
|
||||
|
||||
## Run the artifact, not the source
|
||||
|
||||
Build it and use it the way a user would:
|
||||
|
||||
- **CLI** — build the binary and run it. Happy path, bad input, \`--help\`. Read the output.
|
||||
- **HTTP service** — start it and \`curl\` the endpoint. Check the status and the body.
|
||||
- **Library** — write a throwaway script that imports and calls the new code end to end.
|
||||
- **Script or job** — run it against real input and inspect what it produced.
|
||||
|
||||
Delete the throwaway afterwards.
|
||||
|
||||
## What counts as evidence
|
||||
|
||||
Command output you actually saw. Paste the relevant lines, not a summary of them.
|
||||
|
||||
These are not evidence:
|
||||
|
||||
- "The tests pass" for a change tests do not cover.
|
||||
- "The types check" for anything about runtime behaviour.
|
||||
- "It should work now" for anything at all.
|
||||
|
||||
## Check the failure path too
|
||||
|
||||
Feed it the input you expect to be rejected and confirm it is rejected, with a message
|
||||
that says why. A feature that works only on correct input is half-built.
|
||||
|
||||
## Report what you did not verify
|
||||
|
||||
Say plainly what you could not run and why: a missing credential, a service you cannot
|
||||
start, a platform you are not on. An honest gap is useful; a claim that hides one is not.
|
||||
|
||||
## When verification fails
|
||||
|
||||
The defect is yours to fix in this turn. Do not report the task complete with a note that
|
||||
it did not work.

Never commit unless the user asked. If it is unclear whether they did, ask.

## Look before you stage
|
||||
|
||||
\`git_status\` and \`git_diff\` first. You are looking for two things:
|
||||
|
||||
1. Changes that are not yours. Another agent or the user may share this worktree, and
|
||||
\`git add .\` takes their half-finished work with yours.
|
||||
2. Files that should never be committed: \`.env\`, credentials, keys, large build output,
|
||||
anything a \`.gitignore\` rule was supposed to catch and did not. Flag these to the user
|
||||
rather than committing them.
|
||||
|
||||
Stage the specific paths you changed. \`git add .\` is how unrelated work ends up in a
|
||||
commit that then has to be reverted whole.
|
||||
|
||||
## One commit, one reason
|
||||
|
||||
If the diff does two unrelated things, make two commits. A commit that both fixes a bug and

# Accessibility
|
||||
|
||||
Accessibility is usability for everyone, including people using a keyboard, a screen reader, a
|
||||
magnifier, or a noisy display. Build it in, not on.
|
||||
|
||||
## Semantic HTML does the heavy lifting
|
||||
|
||||
A `<button>`, `<a>`, `<input>`, `<nav>`, `<main>` carries behaviour and meaning for free
|
||||
that a `<div>` with a click handler does not. Reach for the native element first; add ARIA only
|
||||
when no native element fits. The first rule of ARIA is do not use ARIA if a native element exists.
|
||||
|
||||
## Keyboard is the baseline
|
||||
|
||||
- Every interactive element is reachable and operable with Tab and Enter/Space alone.
|
||||
- A visible focus indicator on everything — never `outline: none` without a replacement.
|
||||
- Logical tab order following the visual order, and focus managed into and out of modals,
|
||||
menus, and dialogs (trapped while open, returned to the trigger on close).
|
||||
|
||||
## Screen readers hear structure
|
||||
|
||||
- Headings in order (`h1` once, then down a level at a time) so the page has a navigable outline.
|
||||
- Every `<input>` has a `<label>`; every icon-only button has an accessible name; every image
|
||||
has alt text that conveys its point (or empty alt when it is purely decorative).
|
||||
- Dynamic changes announce themselves: a toast, an error, a loaded region uses a live region so
|
||||
it is heard, not just seen.
|
||||
|
||||
## Contrast and meaning
|
||||
|
||||
Text meets 4.5:1 against its background (3:1 for large text). Colour is never the only carrier
|
||||
of meaning — pair it with an icon, a label, or a pattern. A red-only "error" is invisible to a
|
||||
colour-blind user.
|
||||
|
||||
## Test it the way it is used
|
||||
|
||||
Tab through the whole flow. Turn on a screen reader and listen. Zoom to 200% and 400%. Run an
|
||||
automated checker for the mechanical half — then do the manual half it cannot cover, because
|
||||
most accessibility failures are not machine-detectable.

# API design
|
||||
|
||||
An API is a contract. Every choice is a promise you cannot take back without a major version.
|
||||
|
||||
## Resource before action
|
||||
|
||||
Name things, not verbs. `POST /users` to create, not `POST /createUser`. The URL is the
|
||||
noun; the method is the verb. When you reach for a verb in the path, that is a sign the
|
||||
resource is missing — `POST /users/:id/deactivations` reads better than `/deactivateUser`
|
||||
when the operation has state of its own.
|
||||
|
||||
## Shape the body for the reader
|
||||
|
||||
- Field names are `snake_case` or `camelCase`, picked once for the whole API. A body that
|
||||
mixes both is a body nobody documented.
|
||||
- Return the object, not a wrapper, unless the wrapper carries something: `{ "user": {...} }`
|
||||
only when there is also pagination, a cursor, or an error envelope.
|
||||
- Errors have a stable shape: a machine-readable `code`, a human `message`, and the field
|
||||
that failed. A client should never have to parse the message.
|
||||
|
||||
## Status codes mean something
|
||||
|
||||
- `201` for a created resource, with the resource in the body.
|
||||
- `204` for success with nothing to return.
|
||||
- `400` for a body that failed validation, `401` unauthenticated, `403` authenticated but
|
||||
not allowed, `404` not found or not allowed to know, `409` a conflict with current state,
|
||||
`422` well-formed but semantically wrong.
|
||||
- Never `200` with an error in the body. A client checking only the status will treat it as
|
||||
success.
|
||||
|
||||
## Idempotency and safety
|
||||
|
||||
GET, PUT, DELETE must be safe to retry: same request, same state. POST is not. If a client can
|
||||
double-submit, provide an idempotency key or a natural unique constraint, and say which.
|
||||
|
||||
## Version when you must, not before
|
||||
|
||||
Add fields freely; removing or renaming is a break. If you are not yet committed, say so with
|
||||
a `beta` or `v0` marker rather than locking a shape you have not used. Document the contract
|
||||
you guarantee, not the implementation that happens to produce it.

# CI/CD
|
||||
|
||||
CI is a second machine that does not have your setup. "Works on my machine" means the pipeline
|
||||
is missing something your machine has.
|
||||
|
||||
## Reproduce the environment, not the symptom
|
||||
|
||||
When CI fails and local passes, the difference is the environment: the toolchain version, an
|
||||
uncommitted file, a cache, an env var, the OS. Diff those before touching the code. Read the
|
||||
failing log literally — the first error, not the last, which is usually a downstream echo.
|
||||
|
||||
## Pin everything that can move
|
||||
|
||||
- Toolchain versions (`node`, `bun`, `python`), action versions, base images. `latest`
|
||||
is a build that breaks on a day you did nothing.
|
||||
- Lockfiles go in the repo and the install respects them (`--frozen-lockfile`, `ci`). An
|
||||
install that re-resolves in CI is a different build from the one you tested.
|
||||
|
||||
## Cache the expensive, deterministic part
|
||||
|
||||
Dependencies are the cache; build output usually is not. Key the cache on the lockfile hash so
|
||||
a changed dependency invalidates it. A cache that is too broad serves stale artifacts; too
|
||||
narrow saves nothing.
|
||||
|
||||
## Fail fast, in the right order
|
||||
|
||||
Cheap checks first: lint and typecheck before the test matrix, tests before the deploy. A
|
||||
pipeline that deploys before it verifies publishes the bug it was built to catch.
|
||||
|
||||
## Secrets and deploys
|
||||
|
||||
Secrets live in the CI secret store, never in the file, and are masked in logs. A deploy step
|
||||
is gated: on a tag, on a protected branch, on a manual approval — never on every push. Assume
|
||||
every log line is public and write the pipeline accordingly.

# Committing
|
||||
|
||||
Never commit unless the user asked. If it is unclear whether they did, ask. A commit is a
|
||||
durable statement about shared history, not a save-point.
|
||||
|
||||
## Look before you stage
|
||||
|
||||
`git_status` and `git_diff` first — read the whole diff you are about to commit. You are
|
||||
looking for three things:
|
||||
|
||||
1. **Changes that are not yours.** Another agent or the user may share this worktree, and
|
||||
`git add .` takes their half-finished work with yours.
|
||||
2. **Files that should never be committed:** `.env`, credentials, keys, large build
|
||||
output, anything a `.gitignore` rule was supposed to catch and did not. Flag these to
|
||||
the user rather than committing them — a committed secret is a secret to rotate.
|
||||
3. **Your own accidents:** debug prints, commented-out code, a stray `TODO`, a file you
|
||||
opened and saved by mistake. Revert them before staging, not in a follow-up commit.
|
||||
|
||||
Stage the specific paths you changed. `git add .` is how unrelated work ends up in a
|
||||
commit that then has to be reverted whole.
|
||||
|
||||
## One commit, one reason
|
||||
|
||||
If the diff does two unrelated things, make two commits. A commit that both fixes a bug
|
||||
and renames a module cannot be reverted, cherry-picked, or bisected usefully. Each commit
|
||||
should pass the tests on its own — a series of broken commits defeats `git bisect`.

# Data
|
||||
|
||||
Bad data fails silently and far away from where it entered. Validate at the boundary, keep the
|
||||
raw, and make every transform checkable.
|
||||
|
||||
## Validate at the boundary
|
||||
|
||||
Parse and validate when data enters the system, not when it is used. A schema check at the edge
|
||||
turns a corrupt record into a clear rejection; skipping it turns the same record into a wrong
|
||||
answer three layers later. Reject loudly, with the record and the reason — never coerce and
|
||||
carry on.
|
||||
|
||||
## Keep the raw
|
||||
|
||||
Store the untransformed input alongside the derived. When a transform turns out to be wrong,
|
||||
the raw lets you recompute; without it, the information is gone. Derived data is rebuildable;
|
||||
source data is not.
|
||||
|
||||
## Transformations are pure and tested
|
||||
|
||||
A transform takes input and returns output with no hidden state, so it can be tested on a
|
||||
fixture and re-run safely. Test the edge cases that actually occur in data: the empty field,
|
||||
the wrong type, the unexpected null, the duplicate, the encoding that is not UTF-8.
|
||||
|
||||
## Duplicates, nulls, and ranges are the usual corruption
|
||||
|
||||
Check for: unexpected duplicates on a key, nulls where a value is required, values outside a
|
||||
sane range (a negative age, a date in the future), and referential breaks (an id pointing at
|
||||
nothing). These four catch most real-world data problems before they reach a report.
|
||||
|
||||
## Idempotent pipelines
|
||||
|
||||
A step that can be re-run without duplicating or corrupting its output is a step you can retry
|
||||
after a failure. Key on a stable id and upsert rather than blind-insert. A pipeline you cannot
|
||||
safely re-run is a pipeline you will one day have to fix by hand at 2am.

# Databases
|
||||
|
||||
The schema is the hardest thing to change in the whole system. Design it for the queries, not
|
||||
the object model.
|
||||
|
||||
## Keys and constraints are the real schema
|
||||
|
||||
- Every table has a primary key; prefer a surrogate `id` unless a natural key is truly stable.
|
||||
- Foreign keys and `NOT NULL` are not optional decoration — they are the constraints that stop
|
||||
bad data at the door instead of in application code six months later.
|
||||
- Unique constraints belong on the thing that must be unique (email, slug), enforced by the
|
||||
database, not by a check-then-insert that races.
|
||||
|
||||
## Migrations are one-way and additive where possible
|
||||
|
||||
- Never edit a migration that has run anywhere. Add a new one.
|
||||
- Destructive changes (drop column, rename, change type) are two migrations: add the new shape,
|
||||
deploy code that writes both, then remove the old in a later release. A single migration that
|
||||
renames a column breaks every old copy of the app still running.
|
||||
- Test a migration against real data volume. `ALTER` on ten rows is instant; on ten million it
|
||||
locks the table.
|
||||
|
||||
## Indexes follow the queries
|
||||
|
||||
Index the columns you filter and join on, in the order the query uses them. A composite index
|
||||
`(a, b)` serves `WHERE a` and `WHERE a, b` but not `WHERE b` alone. Read the query plan
|
||||
(`EXPLAIN`) before adding one — a guess is an index that costs writes and serves nothing.
|
||||
|
||||
## The N+1 is the default bug
|
||||
|
||||
A query per row in a loop is the most common database performance defect. Fetch the set with a
|
||||
join or a batched `WHERE id IN (...)`. If a page does one query per item, that is the fix
|
||||
before any caching.

# Debugging
|
||||
|
||||
Do not guess. A guess that happens to work leaves the real cause in place, and it will
|
||||
fire again — usually in production, usually at a worse time.
|
||||
|
||||
## Reproduce first
|
||||
|
||||
Find the smallest command that shows the failure and record it with `remember`. If you
|
||||
cannot reproduce it, say so and ask what the user did differently — do not proceed on a
|
||||
hypothesis you cannot test.
|
||||
|
||||
Shrink the reproduction until it is minimal: one input, one call, one assertion. Every
|
||||
moving part you leave in is a place the bug can hide. A reproduction that takes thirty
|
||||
steps will not get run often enough to confirm the fix.
|
||||
|
||||
## Three hypotheses, then evidence
|
||||
|
||||
Write down at least three causes that would produce this exact symptom — not "the code is
|
||||
wrong" but specific mechanisms: "the offset is off by one when the page is empty", "the
|
||||
cache is read before the write lands". Rank them by how cheap they are to disprove, then
|
||||
disprove them in that order. State which one you are testing before you test it.
|
||||
|
||||
Evidence means observed output: a log line, a failing assertion, a value printed at the
|
||||
point of failure. "It should be X" is not evidence. When the evidence contradicts your
|
||||
favoured hypothesis, the hypothesis is wrong — do not explain the evidence away.
|
||||
|
||||
## Localise before you fix
|
||||
|
||||
Assert the value at each boundary until one is wrong. The bug lives between the last
|
||||
boundary where the value is right and the first where it is wrong. Fixing before you have
|
||||
that bracket means editing the wrong place and learning nothing.
|
||||
|
||||
## Bisect when the space is large
|
||||
|
||||
- Recent regression: `git bisect` or read what changed last. The bug arrived in a commit;
|
||||
find which one.
|
||||
- Unclear layer: assert the value at each boundary until one is wrong.
|
||||
- Intermittent: run it in a loop and capture the failing case with full logging. Do not
|
||||
reason about a race abstractly — make it happen on demand, then it is no longer
|
||||
intermittent.
|
||||
|
||||
## Fix the cause, not the symptom
|
||||
|
||||
Once you know the cause, fix that and nothing else. Do not tidy surrounding code in the
|
||||
same change — a bugfix diff should contain only the bug, so it can be reverted whole if it
|
||||
is wrong.
|
||||
|
||||
Write a test that fails before the fix and passes after. Watch it fail first; a test you
|
||||
never saw fail proves nothing. If you cannot express the bug as a test, say why — and say
|
||||
what you ran instead to confirm the fix.
|
||||
|
||||
## After two failed attempts
|
||||
|
||||
Stop. Re-read the error text literally, character by character — most "impossible" bugs
|
||||
are a misread message. Then check your assumption about which code is actually running:
|
||||
the wrong file, a stale build, a shadowed import, a cached dependency, or an env var that
|
||||
differs from your shell. Verify by printing something at the point you *think* executes;
|
||||
if it does not print, that is your answer.

# Dependencies
|
||||
|
||||
Every dependency is code you did not write but now maintain. Add deliberately, prune regularly.
|
||||
|
||||
## Choose on maintenance, not features
|
||||
|
||||
Before adding: is it actively maintained (recent commits, responsive issues), widely used, and
|
||||
small enough to be worth it? A dependency that saves a day and is abandoned in a year costs a
|
||||
week. For something small and stable, a dozen lines in your own codebase often beats a package.
|
||||
|
||||
## Pin and lock
|
||||
|
||||
Exact versions in the manifest for anything that matters, a lockfile committed, and installs
|
||||
that respect it. A `^` range means your build tomorrow differs from your build today. The
|
||||
lockfile is the build's memory; do not delete it to "fix" a conflict — resolve the conflict.
|
||||
|
||||
## Update on a schedule, read the changelog
|
||||
|
||||
Routine small updates beat a yearly painful one. For a major bump: read the changelog and the
|
||||
migration guide, find every call site of the changed API, and apply one shape of change (see
|
||||
the migrate skill). Update one thing at a time so a regression has an obvious cause.
|
||||
|
||||
## Know your transitive tree
|
||||
|
||||
A direct dependency drags in dozens of transitive ones. Audit the tree for: known
|
||||
vulnerabilities (`audit`/SCA tooling), abandoned packages deep in it, and duplicate copies of
|
||||
the same library at different versions bloating the bundle. Remove what you no longer use — an
|
||||
unused dependency is attack surface and install time for nothing.
|
||||
|
||||
## Supply chain is a trust decision
|
||||
|
||||
A package runs its install scripts with your permissions. Prefer packages with provenance and a
|
||||
reproducible build, be wary of sudden ownership transfers, and pin so a hijacked publish does
|
||||
not reach you automatically. The lockfile is also your audit trail of exactly what shipped.

dependencies means every code change re-runs the install — the single most common Dockerfile
|
||||
mistake.
|
||||
|
||||
## Small images, on purpose
|
||||
|
||||
- Use multi-stage builds: build in a full toolchain stage, copy only the artifact into a slim
|
||||
runtime stage. The compiler does not ship to production.
|
||||
- Pick a slim or distroless base unless you need the tooling. Alpine is small but musl breaks
|
||||
some binaries; know why you chose it.
|
||||
- One `RUN` with `&&` for related steps, cleaning up in the same layer — a separate `RUN rm`
|
||||
does not shrink the image, the data is still in the earlier layer.
|
||||
|
||||
## The container is not a VM
|
||||
|
||||
- One process per container, as PID 1, so signals work. Use an init if the app spawns children.
|
||||
- Do not run as root. Add a user and `USER` it.
|
||||
- Read-only filesystem where possible; write to a mounted volume for anything that must persist.
|
||||
Nothing in the image is writable state.
|
||||
|
||||
## .dockerignore is as important as the Dockerfile
|
||||
|
||||
Exclude `.git`, `node_modules`, build output, and any secret file. A context that sends the
|
||||
whole repo is slow, and a secret copied into an image layer is a secret to rotate.
|
||||
|
||||
## Healthcheck and logs
|
||||
|
||||
The process logs to stdout/stderr, never to a file inside the container — the runtime collects
|
||||
it. Add a `HEALTHCHECK` that proves the service answers, not just that the process exists.

# Documentation
|
||||
|
||||
Docs lie by omission. Write only what you have verified in the code.
|
||||
|
||||
## Ground every claim in the source
|
||||
|
||||
Before documenting a behaviour, read it. A flag, a default, an error message — open the
|
||||
code and quote what it actually does, not what the name suggests. The most damaging doc
|
||||
line is the confident one that was true two versions ago. If the code and the existing
|
||||
docs disagree, the code is right; say so and fix the doc.
|
||||
|
||||
## Answer the reader's actual question
|
||||
|
||||
A reader opens a doc with a task, not a desire for completeness. Lead with the thing they
|
||||
came to do, in the order they will do it:
|
||||
|
||||
- **A reference** lists what exists: every flag, every field, with its default and its type.
|
||||
- **A guide** walks one path to one outcome. Resist documenting every branch — link instead.
|
||||
- **A README** orients in sixty seconds: what it is, install, the first command that works.
|
||||
|
||||
## Show, then say
|
||||
|
||||
A working example beats a paragraph about one. Every command in the doc must be one you
|
||||
ran, with its real output. A snippet that was never executed is a bug waiting for a reader.
|
||||
|
||||
## Match the house style
|
||||
|
||||
Read the neighbouring docs first: their heading depth, their code-fence language tags,
|
||||
their tone. A doc that reads foreign is a doc nobody trusts enough to maintain.
|
||||
|
||||
## Keep it true over time
|
||||
|
||||
Document the stable contract, not the current implementation, unless the point is the
|
||||
implementation. The fewer specifics a doc pins down, the less it rots.

# Frontend
|
||||
|
||||
The user's experience is the metric. Fast, clear, and forgiving beats clever.
|
||||
|
||||
## State lives as low as it can
|
||||
|
||||
Lift state only as high as the components that share it. Global state for something two siblings
|
||||
need is re-render and complexity for everything. Server data is not client state — cache it with
|
||||
the data layer rather than duplicating it into a store you must keep in sync by hand.
|
||||
|
||||
## Rendering is the usual bottleneck
|
||||
|
||||
Before optimising, find what re-renders. A component that re-renders on every parent render
|
||||
because of an inline object or function prop is the common case. Memoize the expensive subtree,
|
||||
not everything — `useMemo` and `useCallback` have a cost too, and slapping them everywhere is
|
||||
its own slowdown.
|
||||
|
||||
## Forms respect the user
|
||||
|
||||
- Validate on blur or submit, not on every keystroke, and show the message at the field.
|
||||
- Never clear a form on an error. The user's input is the most expensive thing on the page.
|
||||
- Disable the submit while submitting, and say what is happening. A double-submitted form is a
|
||||
duplicate record.
|
||||
|
||||
## Accessibility is not a later pass
|
||||
|
||||
Semantic HTML first: a `<button>` that looks like a button beats a `<div>` with a click
|
||||
handler. Keyboard-reachable everything, visible focus, labels on inputs, alt text that conveys
|
||||
the point not the pixels. Colour is never the only carrier of meaning.
|
||||
|
||||
## Measure what the user feels
|
||||
|
||||
Load: get the first meaningful paint and the time-to-interactive down before micro-tuning.
|
||||
Bundle: split the route nobody opens, lazy-load the heavy component. A Lighthouse number is a
|
||||
proxy; the goal is that it never feels slow.

# Git workflow
|
||||
|
||||
History is a communication tool. Write it for the person who reads it in six months — usually you.
|
||||
|
||||
## One branch, one purpose
|
||||
|
||||
A branch that does two things produces a PR that can only be reviewed as all-or-nothing and
|
||||
reverted only whole. Keep it small and single-purpose; open the second thing as its own branch.
|
||||
|
||||
## Rebase to clean up, merge to preserve
|
||||
|
||||
- Rebase your own unpushed work freely: it makes a linear, readable history.
|
||||
- Never rebase a branch others have pulled — it rewrites commits they have, and the next pull
|
||||
becomes a mess. Merge shared branches instead.
|
||||
- Interactive rebase before opening the PR: squash the "fix typo" and "wip" commits into the
|
||||
change they belong to. The PR should read as a series of intentional steps, not a diary.
|
||||
|
||||
## Recover without panic
|
||||
|
||||
- `git reflog` finds almost anything you "lost": the branch you deleted, the commit you reset
|
||||
away. Nothing committed is truly gone for ~30 days.
|
||||
- A bad merge: `git merge --abort`. A bad rebase: `git rebase --abort`. Both stop cleanly
|
||||
rather than pushing forward into a worse state.
|
||||
- Committed to the wrong branch: `git reset --soft` to keep the work, switch, recommit.
|
||||
|
||||
## The commit message is the review's first page
|
||||
|
||||
Subject under 70 chars, imperative, says what changed. Body explains *why* when it is not
|
||||
obvious. A reviewer who cannot tell why a change exists from its message will ask, or worse,
|
||||
approve without understanding.
|
||||
|
||||
## Read the conflict, do not guess
|
||||
|
||||
On a conflict, open the file and understand both sides before resolving. Taking "ours" or
|
||||
"theirs" wholesale because it is faster is how a resolved conflict silently drops someone's
|
||||
work.

# Internationalisation
|
||||
|
||||
Hard-coded English is a bug in every other language. Externalise strings and never assume a
|
||||
grammar.
|
||||
|
||||
## Every user-facing string is a key
|
||||
|
||||
No string in the UI lives in code; it lives in a message catalogue under a key. Concatenating
|
||||
translated fragments is the classic bug: "You have " + n + " messages" cannot be reordered for
|
||||
a language whose grammar puts the number elsewhere. Use a format with named placeholders:
|
||||
`{count, plural, ...}`, translated as a whole.
|
||||
|
||||
## Pluralisation and gender are not English
|
||||
|
||||
Languages have one, two, several, or no plural forms, with rules that do not map to "1 vs other".
|
||||
Use the ICU plural machinery of your i18n library and let the translator fill in every form the
|
||||
locale needs. The same goes for gendered agreement.
|
||||
|
||||
## Format dates, numbers, and currencies by locale
|
||||
|
||||
Never `dd/mm/yyyy` by hand: `03/04/2025` is March 4th to one user and April 3rd to another.
|
||||
Use the platform's locale-aware formatter (`Intl.DateTimeFormat`, `Intl.NumberFormat`).
|
||||
Store and transmit ISO 8601 / UTC; format for display only.
|
||||
|
||||
## Layout breaks in translation
|
||||
|
||||
German runs ~30% longer than English; some scripts are right-to-left. Flexible layout, no fixed
|
||||
widths on translated text, and CSS logical properties (`margin-inline-start` not
|
||||
`margin-left`) so RTL mirrors correctly. Test with a pseudo-locale that lengthens and accents
|
||||
every string to find the overflows before a translator does.
|
||||
|
||||
## Sort and search correctly
|
||||
|
||||
String order is locale-dependent: `ä` sorts with `a` in German, after `z` in Swedish. Use
|
||||
locale-aware collation (`Intl.Collator` or the database's) rather than byte order, and normalise
|
||||
Unicode before comparing, because the same character has more than one byte representation.

# Incident response
|
||||
|
||||
Mitigate first, diagnose second. Restore service, then find out why.
|
||||
|
||||
## Confirm and scope before touching anything
|
||||
|
||||
What is actually broken, for whom, since when? Check the signal, not the report: the dashboard,
|
||||
the error rate, the health endpoint. A wrong scope sends you chasing a symptom. State the impact
|
||||
plainly in one line before you start changing things.
|
||||
|
||||
## Recent change is the prime suspect
|
||||
|
||||
Most incidents follow a deploy, a config change, a flag flip, or a scaling event. What changed
|
||||
in the window before it broke? Check the deploy log and the diff. The fastest fix is usually to
|
||||
undo the last change, not to understand it.
|
||||
|
||||
## Mitigate, then understand
|
||||
|
||||
- Roll back the deploy, flip the flag off, fail over, scale up, restart the wedged process —
|
||||
whichever restores service fastest, even if you do not yet know the root cause.
|
||||
- A mitigation you can reverse beats a perfect diagnosis that takes an hour. Note what you did so
|
||||
it can be undone or made permanent later.
|
||||
- Do not deploy an unreviewed "fix" into the fire; it adds a second change to a system already
|
||||
misbehaving.
|
||||
|
||||
## Preserve evidence before it rotates away
|
||||
|
||||
Capture the logs, the error, the relevant metrics, a snapshot of the state — before a restart or
|
||||
a rollback destroys it. You will want it for the postmortem, and it may be the only copy.
|
||||
|
||||
## Communicate and follow up
|
||||
|
||||
Say what is broken, what you are doing, and when the next update is — to whoever is affected,
|
||||
in plain language, on a schedule. Afterwards: write the timeline, the root cause, and the
|
||||
follow-ups that stop it recurring. An incident with no follow-up is a loan against the next one.

# Logging
|
||||
|
||||
Logs are how you debug a system you cannot attach a debugger to. Write them for the 3am
|
||||
incident, not the happy path.
|
||||
|
||||
## Structure over prose
|
||||
|
||||
Emit fields, not sentences: `{ user: id, action: "checkout", ms: 142, ok: false }`, not
|
||||
`"User checked out"`. Structured logs are searchable and aggregable; a sentence is neither.
|
||||
One event, one line, one level.
|
||||
|
||||
## Levels are a contract
|
||||
|
||||
- `error` — something is broken and someone should look. Not "a user gave bad input".
|
||||
- `warn` — unexpected but handled; worth a glance.
|
||||
- `info` — the meaningful state transitions: started, finished, the decision made. Sparse.
|
||||
- `debug` — everything you might want while diagnosing, off in production.
|
||||
|
||||
A log at the wrong level trains people to ignore the right one. If everything is `error`,
|
||||
nothing is.
|
||||
|
||||
## Log the decision points, not every line
|
||||
|
||||
At a boundary — a request in, a call out, a branch taken — log what was decided and the inputs
|
||||
that decided it, with a correlation id that follows the request across services. You should be
|
||||
able to trace one request end to end from the id alone.
|
||||
|
||||
## Never log a secret
|
||||
|
||||
No passwords, tokens, session ids, full card numbers, or personal data beyond what policy
|
||||
allows. Redact at the point of logging, not by hoping a downstream filter catches it. A secret
|
||||
in a log aggregator is a secret to rotate.
|
||||
|
||||
## Measure, do not just log
|
||||
|
||||
For anything with a latency or a rate, a metric answers "is it slow?" faster than a thousand
|
||||
log lines. Logs explain *why*; metrics tell you *that* something is wrong in the first place.

# Migration
|
||||
|
||||
The failure mode is a half-applied migration: it compiles, most tests pass, and one code
|
||||
path still uses the old API.
|
||||
|
||||
## Read the changelog before the code
|
||||
|
||||
Find what actually broke. A major version usually has a migration guide; read it and list
|
||||
the changes that apply to this codebase specifically. Below 1.0, treat a minor bump as
|
||||
breaking — semver promises nothing there.
|
||||
|
||||
## Find every call site before changing one
|
||||
|
||||
Grep for the old API across the whole repository, including tests, scripts, config, CI
|
||||
workflows, Dockerfiles, and documentation. A version literal pinned in a workflow while the
|
||||
manifest says something else is a split-brain deploy.
|
||||
|
||||
Write the list down with `todo_write`. The list is the migration; the edits are mechanical.
|
||||
|
||||
## Change in one shape
|
||||
|
||||
Apply the same transformation everywhere rather than improving each site as you pass
|
||||
through it. A migration mixed with refactoring cannot be reviewed, and cannot be reverted
|
||||
if the upgrade turns out to be wrong.
|
||||
|
||||
`apply_patch` is the tool for this: one atomic patch across the files that must land
|
||||
together.
|
||||
|
||||
## Verify at the boundary that broke
|
||||
|
||||
Type checks catch signature changes and miss behaviour changes — the two ways a migration
|
||||
actually breaks you. Run the tests, then actually *use* the thing that was upgraded: start
|
||||
the server, run the CLI, execute the query, hit the endpoint. A green suite over an
|
||||
untested upgrade path proves only that the suite did not cover it.
|
||||
|
||||
Pay special attention to silent behaviour changes: a default that flipped, a deprecated
|
||||
call that still runs but does something subtly different, an error type that changed shape.
|
||||
These compile, pass type checks, and still break production.
|
||||
|
||||
## Never hand-merge a lockfile
|
||||
|
||||
On a conflict, take either side whole and regenerate with the package manager. The resolver
|
||||
owns that file; a hand-merge is a split-brain dependency tree that installs differently on
|
||||
every machine.
|
||||
|
||||
## Report
|
||||

||||
