Muhammad Zakir Ramadhan f8c3cc2d8e Ship the batch: undo, parallel subagents, lazy MCP, hot-reloaded skills; docs and CI/CD
Loop and ergonomics batch across Now/Next and Maintenance:
- /undo and /redo via pre-prompt file snapshots (snapshot.ts)
- task takes a tasks[] array and runs investigations concurrently (subagent.ts)
- lazy MCP tools: mcp_list/mcp_inspect/mcp_call meta-tools, eager opt-in (mcp.ts, config.ts)
- skill tool reads its list live so a mid-session install is callable next turn (skills.ts)
- tool-name lists (tool-kinds.ts) derived from a mutating() marker; gates previously ungated writes
- prune/session recovery path summarized, and step-back doom-loop primitive (step-back.ts)
- @file completion re-walks on a slow cooldown; estimateTokens and pricing labeled as estimates

Docs: README, CHANGELOG, docs/{mcp,architecture,development} updated to match.
CI/CD: bun install-store cache and concurrency gates on both workflows; release.yml now
composes file-based release notes via scripts/make-release-notes.ts and verifies every binary.

# TODO
Next up. One item, one outcome, verifiable when done.
Longer-term direction lives in [ROADMAP.md](ROADMAP.md).
---
## Now
### Summarize the pruned span
Compaction now keeps the model's memory of a turn, but it still tells the model nothing about
the messages it dropped, so a decision from forty messages ago can be contradicted with
confidence.
- [x] Summarize the discarded messages before dropping them
- [x] Inject the summary in place of the count
- [x] Budget it: a summary that grows with the session defeats the point
- [x] Test: a pruned decision is still recoverable from the summary
### Hot-reload an installed entry
`/registry add` writes the file and says to restart. The skill catalogue and the guard chain
are both assembled at boot, so a mid-session install does nothing until then.
- [x] Rebuild the skill list and plugin host after an install or removal
- [x] Leave a turn in flight alone: its rules must not change underneath it
- [x] Test: a skill installed mid-session is callable in the next turn without a restart
> Partial: skills reload live (the `skill` tool reads its list on each call); plugins and
> external tools still need a restart because they join the guard chain and the tool registry,
> both built once at boot.

## Next
### MCP without the schema tax
Every MCP tool's schema goes into the prompt today, so twenty tools from one server cost roughly
2,750 tokens per request whether the model uses them or not. `toolSets` does not gate them.
phi solves this with three meta-tools — `mcp_list`, `mcp_inspect`, `mcp_call` — and a prompt that
names only the servers. A hundred servers then cost almost nothing until one is called.
- [x] `mcp_list` / `mcp_inspect` / `mcp_call` replacing per-tool registration
- [x] The prompt lists server names, not schemas
- [x] Calls go through the same permission rules and guard as a built-in
- [x] Keep per-tool registration as an option: a two-tool server is cheaper registered directly
- [x] Test: a configured server contributes no schema to the request until `mcp_call`
> Switchable with `mcpMode: 'eager'` in config; lazy (meta-tools) is the default.
### Derive the tool-name lists
`TOOL_SETS` and `MUTATING_TOOLS` both list names by hand. A tool added to one and forgotten
in the other is a silently ungated write, which is the worst kind of bug this codebase can
have.
- [x] Mark each tool as mutating where it is defined, not in a list beside it
- [x] `TOOL_SETS` covers every registered tool, checked rather than assumed
- [x] Test: a tool in no set, or a mutating tool outside `MUTATING_TOOLS`, fails the suite
> While doing this, two mutating-but-ungated tools surfaced and were gated: the registered set
> is now derived from the `mutating()` marks.
### Subagent parallelism
Two independent searches run sequentially. The panel already renders several agents; the loop
does not fan out.
- [x] `task` accepts several investigations and runs them together
- [x] Test: two delegated searches overlap in time rather than queueing
> `tasks` on the `task` tool runs them concurrently via `Promise.all`; a call without it behaves
> exactly as before.
### Undo a turn
Every comparable CLI has this: opencode `/undo` and `/redo`, Claude Code `/rewind` with
checkpoints. There is `/resume` here, which restores a session, and nothing that walks one back.
- [x] Snapshot files before each prompt, capped at the 100 most recent
- [x] `/undo` restores files, conversation, or both; `/redo` reverses it
- [x] Say plainly what is not covered: a `bash` command's effects cannot be snapshotted
- [x] Test: an edit is reverted, and the model's own record of it goes with it
---
## Maintenance
- [x] Pricing table needs a source note and a date; rates drift and ours are hand-entered
- [x] `estimateTokens` divides JSON length by four. Good enough for a compaction threshold,
wrong enough to mislead in `/cost`. Either label it an estimate everywhere or use a
real tokenizer
- [x] `listPaths` walks up to 5000 files once per session. Fine for a repo, wasteful in a
monorepo, and it never notices a file created after the first `@`
- [x] `MUTATING_TOOLS` is now only used by tests and docs; the permission defaults are what
actually gate a write. Either delete it or make the defaults derive from it
---
## Known rough edges
Not bugs exactly, but things that will bite someone.
- **`/clear` wipes the terminal scrollback.** `<Static>` output is already committed, so
clearing React state alone leaves it on screen. The escape sequence works but takes the
user's earlier terminal history with it.
- **Memory has no conflict resolution.** Two contradictory notes both persist and both get
injected. `/memory` may merge them, or may keep both.
- **Windows `cmd /c` differs from `bash -lc`.** A command the model writes for one shell may
fail on the other. The prompt states the platform; it does not translate.
- **An unknown name in `toolSets` is dropped silently.** The header line shows which sets
actually loaded, but a typo reads as "that set is off" rather than as a mistake.
- **Permission rules gate the call, not what it does.** `bash` with `git *` allowed will run a
`git` alias that shells out to anything, and there is no sandbox around the shell. Codex solves
this with OS-level isolation — Seatbelt, Landlock, a Windows equivalent — which is three
platform-specific implementations and not something to half-ship.
- **The reasoning panel is per-turn, not per-step.** Reasoning from an early step stays on
screen through later ones until the turn ends.
- **An interrupted command's effects are unknown, and the model is told so.** Nothing can know
how far a half-run migration got.
- **`@` completion lists files, not directories.** `@src/` narrows correctly, but you cannot
complete to `src/` itself, because the walker only yields files.
- **An installed skill is a stranger's words in your system prompt.** The install shows the
body first and `/skills` records the origin, but nothing re-checks it later: a registry that
changes a URL's contents affects the next install, not one already on disk.
- **A registry index is trusted for its contents, not its authorship.** There are no
signatures. `registryUrl` is the whole trust decision.

## Done
Kept for one release, then deleted. The 1.0.0 release batch:
- [x] A spend ceiling (`maxSpendUsd`): checked before each turn, refused at 100% naming the
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
- [x] Twenty new built-in tools (41 total) in a new `extra` set: line edits, filesystem
navigation, read-only git extensions, and code/environment reads
- [x] Twenty new bundled skills (29 total) plus the eleven originals deepened; all moved to
`src/skills-md/*.md` as the Markdown source of truth, embedded at build
- [x] Ten new data-only plugins: safety refusals on by default (force push, pipe-to-shell,
root, env credential writes) and opt-in workflow plugins (conventional commit,
tests-first, small diffs, main-branch commits, git config, confirm-delete)
- [x] Custom slash commands from Markdown files, with `$ARGUMENTS`/`$1` and guarded shell
substitution; a custom command never shadows a built-in
- [x] Auto-loaded external skills, tools, and plugins from `~/.shiro-neko/<kind>` and
`.shiro/<kind>`, all data, never code; a bad file is reported and skipped
- [x] The welcome interface redesigned into a structured dashboard with a session banner, a
grouped environment panel, and a meta bar; the input in a two-tone box with a split footer
- [x] The system prompt advanced: a failure-recovery loop, a delegation policy, compaction awareness
- [x] The release workflow's dead `dry_run` input wired: manual dispatch publishes only when
unchecked, tag pushes always publish
- [x] A visible escape hatch for the stalled-agent loop: the existing repeat guard now offers a
configurable `step_back` recovery primitive that reads the session loop trace and steers a
model circling without progress to stop and change direction
