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.
worker holds the write tools and routes every write and command through the parent's approval gate: same permission rules, same guard, same prompt, flagged as coming from a subagent. Without an approval channel, as in headless runs, the kind is not offered at all rather than silently downgraded to read-only.

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.
