Each tool line carries the arguments that identify the call - the paths a batch read is about to pull in, the files a patch touches - and its result line carries a one-line outcome. Worker approvals are labelled as subagent asks, and a subagent result attaches to its step in the panel.

The compaction bug, which is the important one:
beta.2 taught the pruner to drop any assistant part whose reasoning item it had
removed. That was right about the 400 and wrong about everything else. On a
reasoning model every tool call carries a provider itemId, so past the threshold
the model could no longer see what it had already run, and re-ran the same tools
until maxSteps ended the turn. Reproduced at 12 model calls for a job needing 4,
with nothing but the user message reaching the wire.
The dependency is not the part, it is the itemId. A part carrying one is
serialised as `{ type: 'item_reference', id }`, a pointer to an item stored
provider-side that depends on its reasoning item. Without the itemId the same
content goes out inline and carries no dependency at all. Verified against the
provider's own serialiser: `text` with an itemId becomes item_reference, the
identical part without one becomes output_text.
So `dropOrphanedItems` becomes `detachOrphanedItems`: strip the itemId, keep the
content. Compaction may shorten the history; it must not blank it. The new test
asserts behaviour rather than shape — the loop must end because the model chose
to, and every call after the first must still carry the earlier exchange. A shape
assertion passed the whole time the model was losing its memory.
Registry, via `/registry [list|search|add|remove|installed]`:
Skills and plugins are treated differently on purpose. A skill is prompt text, so
installing one puts a stranger's words into the system prompt of every future
session in this project; the install shows the body first and the origin is
recorded, so /skills always says where an instruction came from. A plugin is a
JSON manifest of deny rules, evaluated by compiled code identical for every
install. Loading TypeScript from a URL is declined outright: a plugin that can
block tool calls could otherwise lie about blocking them.
Validated before anything is written: https only (file: and data: rejected), name
matched against ^[a-z0-9][a-z0-9-]*$ so it cannot escape its directory, size
caps on index and body, every regex compiled, pattern length capped since it runs
on every tool call, and the body's own name checked against the index. Installed
skills rank below your own, so an install can never shadow a skill you wrote.
Interface:
- Context is a percentage of the compaction threshold, amber from two thirds and
red at 90. A turn about to lose history now says so beforehand.
- Aligned command menu and registry tables; /skills and /plugins name origins.
538 tests, up from 488. The registry is tested against a real local HTTP server,
and the guard is proven to refuse a .env write end to end rather than assumed to.
Tools, six built-in to fourteen:
- read_many_files: up to 20 paths read concurrently, each with its own window.
An unreadable path is reported in its own block instead of throwing.
- multi_edit: several edits to one file, validated in memory first so a late
failure cannot leave the file half-written.
- list_dir: ignore-aware depth-limited tree.
- git_status/diff/log/show/blame: read-only, spawned with a fixed argv rather
than a shell string, which is what makes them safe to auto-approve.
toolSets gates them. core is always on; edit-plus and git are optional. A
disabled set reaches neither the wire nor the system prompt, since a prompt
naming an absent tool teaches calls that cannot succeed.
Interface:
- Reasoning streams to a collapsed panel, ctrl-r expands, dropped when the turn
ends: it is progress, not the answer.
- The tool in flight is named from tool-input-start, before its arguments finish
streaming, and cleared on its result.
- Prompts typed mid-turn queue and drain in order. esc clears the queue as well
as aborting.
- @ opens a path picker fed by the ignore-aware walker. Prefix matches rank
above substring matches, so @src/ means "under src/". The walk runs on the
first @, not at startup.
ctrl-c kills the command in flight and keeps the turn. The call throws rather
than returning, so the model cannot read a killed command as one that ran and
failed on its own terms. The kill takes the whole process tree: killing cmd /c
alone left the real command holding both pipes open, so the read never returned
and the interrupt did nothing for 19 seconds.
Two pruning fixes:
- A tool result whose tool call was pruned is now dropped with it. Pruning
counts messages, so the cut landed between an assistant tool-call and the tool
message answering it, producing 400 "No tool call found for function call
output with call_id ...". The reverse pairing is left alone: a call awaiting
its result is what a suspended approval looks like.
- ignore.ts called statFs without importing it, so walk() crashed on the first
symlink.
482 tests, up from 404. Docs synced across README, ROADMAP, TODO, and all of
docs/: tool sets, the new tools, ctrl-c semantics, the tool-start event, and the
two hand-maintained tool-name lists recorded as a known weakness.
Agentic coding CLI on Bun, Ink, and the AI SDK.
Core: streamText loop with SDK-level tool approval so a denied call provably never executes; endpoint fallback for OpenAI reasoning models; retry with backoff.
Tools: read/write/edit/glob/grep/bash, path-jailed, gitignore-aware, ripgrep with a JS fallback, binary rejection, live bash streaming.
Agents: five variants crossing thinking level with tool restriction; plan and review withhold mutating tools from the model.
Extensibility: frontmatter skills with on-demand bodies, plugin host with blocking hooks, MCP stdio and HTTP, read-only subagents.
State: durable per-project memory, session task lists, session persistence, compaction that repairs provider-item dependencies.
Distribution: five-platform cross-compiled binaries with checksums, install scripts, CI on three operating systems.
404 tests, typecheck clean.
