 # Auto-scaffold project workflow files on first use in an existing repo
 ## Problem
 `/init` already scaffolds TODO.md / ROADMAP.md / docs/ **manually** (plus writes AGENTS.md
 via the model). But when the user runs shiro against an *existing* project that has no
 tracking files, nothing is generated automatically — the workflow policy block stays out of
 the system prompt, no nudges ever fire, and the model has no task list context.
 The user's ask: when the agent starts working in an existing repo that lacks
 TODO.md / ROADMAP.md / docs/, generate them (also auto-write AGENTS.md), so the workflow
 hooks in before the first turn.
 ## Scope
 - Auto-generate TODO.md, ROADMAP.md, docs/, and AGENTS.md in an existing repo that has none
  of them, before the first user turn.
 - Model-driven content (the `/init` prompt pattern) rather than empty templates, so the
  files reflect the actual project.
 - Opt-out: `workflow.autoScaffold: false` disables; `workflow.enabled: false` stays the master
  switch. Also bail if the repo already tracks anything (TODO/ROADMAP/docs or AGENTS.md) — a
  repo that self-tracks does not need re-scaffolding.
 - Generated files are surfaced as a `notice` event so the CLI/UI can show them.
 - No overwriting: never touch an existing file.
 ## Files touched
 - `src/scaffold.ts` — add `scaffoldMissingAuto(cwd, model)` that (a) checks git root,
  (b) if no TODO/ROADMAP/docs/AGENTS.md exist, generates them via one model call
  (reuse `INIT_PROMPT`-style tone, but cover all four files), writing directly.
 - `src/session.ts` — in `send()` (first turn only, `workflow.autoScaffold !== false` and
  `workflow.enabled !== false`), call `scaffoldMissingAuto` once; if anything was written,
  set a flag so `systemFor()`'s `workflowPolicy()` sees the files right away, bump
  `versions.workflow`, and yield a `notice`.
 - `src/config.ts` — parse `workflow.autoScaffold` from config.
 - `src/session.ts` `SessionOptions.workflow` — add `autoScaffold?: boolean` (default true).
 - `test/scaffold.test.ts` (new or extend) — auto-scaffold on a repo with nothing; bail when
  TODO.md exists; bail when AGENTS.md exists; opt-out flag.
 - `docs/workflow.md` — document auto-scaffold + the flag.
 ## Verification
 - `bun run typecheck` clean.
 - `bun test` full suite green.
 - New tests cover: auto-scaffold writes 4 files in a bare repo; existing TODO.md bails;
  existing AGENTS.md bails; `autoScaffold:false` skips; notice event emitted.
 - `bun run build` compiles.
 ## Risks / decisions
 - One model call for all four files keeps it cheap and atomic-ish; content is project-specific.
 - Runs once per session (flag), at first `send()` *before* the model's real turn, so the
  system prompt and the turn see it. If the model call fails, degrade to the existing
  `scaffoldWorkflowFiles` empty-template fallback — never fail the turn.
 - Cwd-relative writes: resolve against the **git root**, not `process.cwd()` (matches
  `workflowPolicy`). Nested-cwd runs still write at the repo root.

 # Background bash — run long-lived commands without blocking the turn
 Status: spec (implemented)
 Date: 2026-09-11
 ## Problem
 Running a dev server (or any long-lived command) via `bash` blocks the tool
 until the process exits or the 120 s default timeout fires. A dev server never
 exits, so the model burns the turn waiting, then gets a killed-by-timeout error
 in which the server may or may not still be running. Dev workflows inside the
 agent are effectively impossible.
 ## Design
 Add an optional `background: true` mode to `bash`. Background commands:
 - spawn detached (new process group / session) so the agent process can exit
  without taking them down, and so ctrl-c in the agent never kills them.
 - return immediately with a `handle` (small integer), a `started` marker, and
  the first few lines of output (when available).
 - keep streaming output into a per-handle ring buffer (capped) in memory;
  `bash_status` returns recent output and the current running/finished state.
 - are reaped on agent shutdown — the module saves a `~/.shiro-neko/backgrounds.json`
  journal and kills live children on exit (kill `Bun.spawn` process).
 - can be killed explicitly via `bash_stop` (the tool), or ctrl-c while focused,
  or `/bash` (the command).
 ### Why a handle + tools, not a long-lived "bash" result
 Background processes are by definition not one-shot, so a single tool result
 cannot represent them. Separating into `bash` (start/one-shot) + `bash_status`
 (poll) + `bash_stop` (kill) keeps each tool's contract small and lets the agent
 poll while continuing to work. The model is instructed to poll and stop when
 done; otherwise the process lingers until shutdown reaps it.
 ### Why detached
 `Bun.spawn(..., {detached: true})` (a.k.a. setsid) is required so that:
 - killing the agent does not SIGKILL the dev server (kill process-group on exit
  is deliberate, see below);
 - ctrl-c in the agent (which kills the agent's own process group) does not
  signal the dev server;
 - `interruptBash()` keeps working for foreground commands only.
 On Windows, process groups work differently (`detached` behaves differently in
 Bun; the kill is best-effort). Document that background is primarily for
 Unix-like dev servers.
 ## Tool changes
 ### `bash` — add `background?: boolean` and `name?: string`
 - `background` default false (foreground = existing behavior, backward compat).
 - `name` optional label used for /bash listing.
 - When background:
  - spawn `bash -lc '<cmd>'` with `detached: true` (or `cmd /c` + best-effort on
    win32), pipes captured for streaming, no tool timeout (the process decides
    its own lifetime).
  - register in the module-level `backgrounds` map keyed by an incrementing
    handle.
  - return `running <handle>: <cmd> (background pid N)` — the model learns the
    handle and can poll.
 - The `running` map (foreground, `interruptBash`) is untouched: foreground
  commands still behave exactly as today.
 ### `bash_status` — new `nav`/`core` read tool
 - Input: `handle: number`.
 - Output: one of:
  - `running`: `status: running (pid N)\n<recent output, tail capped>`
  - `finished`: `status: finished, exit: <code>\n<tail of captured output>`
  - `not found`: `status: no such handle`
 - Implementation reuses `bashListener` streaming (sessions get live progress
  while a background command runs) and keeps a tail buffer per handle
  (`MAX_OUTPUT`-capped, so the model never burns context).
 ### `bash_stop` — new mutating tool
 - Input: `handle: number`.
 - Returns which command was killed (`killed <handle>: <cmd>`), or
  `no such handle` when absent. Reuses `killTree` (process-group aware) on the
  background process, awaited so the process really is gone.
 ### Tool registrations
 - `bash_status`: `withMeta({ set: 'core', mutating: false })`, read tool, no
  approval needed (like `read_file`).
 - `bash_stop`: `withMeta({ set: 'core', mutating: true })` — mutating requires
  a `DEFAULT_PERMISSIONS` entry + `subjectOf` case in `src/permission.ts`
  (falls back to `ask` on `*` otherwise, bypassing command gating).
 - `bash` remains `mutating: true`; `bash_stop` and `bash` share the bash
  permission subject (`bash` subjectOf: `bash_stop` command = `bash <cmd>`),
  so an approved `bash` rule can also cover `bash_stop` (subject-derived).
 - `MUTATING_TOOLS`/`TOOL_SETS` derive automatically via `_meta`.
 ### Default permissions
 - `bash_stop` added to the mutating loop list (`src/permission.ts:223`).
 - `subjectOf` (`src/permission.ts:306`) maps `bash_stop` → `'bash'` so existing
  bash rules apply (e.g. a blanket allow on `bash` covers stop).
 ## Session / UI
 - `src/session.ts` streams background command output through the existing
  `onBashOutput` listener (live output panel in interactive mode, same as a
  foreground command's streaming).
 - `src/ui/App.tsx`: render the `[bg N]` prefix from the `bash` tool result and
  make ctrl-c while no foreground command is running stop the most recently
  started background command (mirror of `interruptBash`). Keeps esc semantics:
  with a foreground command running, esc still kills it first.
 - `src/commands.ts`: `/bash` command — `list` (default) shows
  `handle: cmd (running|exit N)`, `stop <id>` kills, `stop all` kills all.
  Parser case in `commands.ts`, UI switch in `App.tsx`.
 - `src/cli.tsx` shutdown: before `process.exit`, call
  `shutdownBackgrounds()` (async kill live children + write journal).
  Best-effort — must not throw or delay exit. Journal written to
  `~/.shiro-neko/backgrounds.json` (SHIRO_HOME-aware via `store.ts` patterns).
 ### Prompt guidance
 - `src/prompt.ts` bash tool descriptions: note that long-lived commands
  (dev servers, watchers, tests that run forever, `bun dev`) should use
  `background: true` and then be polled with `bash_status` and stopped with
  `bash_stop` when done. Instruct the model to always stop what it starts.
 ## Files touched
 - `src/tools.ts` — bash background branch, `bash_status`, `bash_stop`,
  registry entries, `bgHandle` counter, `backgrounds` map, `killBackground`.
 - `src/tool-utils.ts` — no change (meta derives).
 - `src/permission.ts` — mutating list + `subjectOf` + DEFAULT_PERMISSIONS.
 - `src/prompt.ts` — tool descriptions / guidance (bash description + status/stop).
 - `src/session.ts` — listener wiring (streaming bg output) if not already
  covered by `onBashOutput`; nothing else needed.
 - `src/commands.ts` — `/bash` command definition + parser case.
 - `src/ui/App.tsx` — `/bash` switch case + ctrl-c background fallback.
 - `src/cli.tsx` — shutdown reaping + journal.
 - `test/tools.test.ts` — bg tests.
 - `test/permission.test.ts` — auto (bash_stop mutating coverage).
 - `test/commands.test.ts` — `/bash` parse + list/stop.
 ## Verification
 - `bun test` (665+ tests, new ones included: `sleep 30` background returns
  immediately; status shows running then finished after `exit 0`; stop kills;
  journal + reap on shutdown; `/bash list/stop` parse).
 - `bun run typecheck`.
 - `bun run build` (must pass `--production`; `dist/shiro --version`).
 - Manual: `SHIRO_HOME=$(mktemp -d) bun run src/cli.tsx -p "run a dev server in
  the background and check it is up, then stop it" --yolo --json`.
 ## Risks / notes
 - Old journal entries (from crashed sessions) are reaped on next boot: at
  startup, kill stale PIDs or ignore missing ones. Do not leak orphan dev
  servers across sessions.
 - `bash_status` poll output is capped (context safety).
 - Windows: background is best-effort (no process group / setsid semantics);
  foreground behavior unchanged.
 - Background processes are not snapshot / undo targets; killing on shutdown
  is deliberate to avoid orphan servers the user cannot see.

 # Maintenance polish — spec
 ## 1. Pricing source+date
 File: `src/pricing.ts`
 - Add file-level doc: source URLs (anthropic.com/pricing, openai.com/api/pricing, etc) + `Last verified: 2026-09-09` + note "hand-entered, verify before billing".
 - Keep RATES as is (no rate change unless verified), but comment per-provider source.
 - Export `PRICING_VERIFIED_AT = '2026-09-09'` for /cost panel to display.
 ## 2. estimateTokens label
 Files: `src/prune.ts`, `src/session.ts`, `src/ui/panel-bodies.ts`
 - `estimateTokens` already `len/3.6+8*msgs` with ~. Rename display everywhere to `~N tokens (est.)` or keep `~N` but add `(est.)` in /cost.
 - Ensure `session.estimatedTokens()` doc says "estimate, not tokenizer".
 - `costPanel` line already `~${n} tokens` -> change to `~${n} tokens (est.)`.
 ## 3. listPaths staleness
 Files: `src/cli.tsx`, `src/ui/App.tsx`, `src/ignore.ts`
 - Problem: `listPaths` walks 5000 once, caches in App `paths` state, never refreshes.
 - Fix:
  - `cli.tsx` hooks.listPaths accepts `opts?: { force?: boolean }` and caches with 30s TTL + invalidation on file mutation via `session` snapshot hook (expose `invalidatePaths` or simple: App re-calls walk when file created).
  - Simplest reliable: App keeps `pathsVersion` bump; Session emits `onFileMutated` callback that App subscribes to -> `setPaths(undefined)` so next `@` re-walks. Also add manual refresh: `ctrl-r` while FileMenu open re-walks (or just always re-walk after 30s).
  - Implementation: add `fileChangeSeq` counter in Session, increment on recordBeforeWrite commit; App `useEffect` watches `session.fileChangeSeq` and invalidates `paths`.
  - Keep limit 5000, but add comment "refresh on file mutation, manual Tab still works".
 ## 4. MUTATING_TOOLS derive
 Files: `src/permission.ts`, `src/tool-utils.ts`, `src/tools.ts`
 - Today `MUTATING_TOOLS = mutatingNames(tools)` (derived from _meta) and `DEFAULT_PERMISSIONS` hand-lists `write_file:'ask'` etc — two sources.
 - Fix: make DEFAULT_PERMISSIONS derive mutating entries from MUTATING_TOOLS. Keep special-case reads (`read_file` etc) explicit, then loop MUTATING_TOOLS to set `'ask'` unless already present. This makes _meta single source.
 - Keep `MUTATING_TOOLS` exported (tests use it) but add comment "single source via _meta".
 - Also add `FREE` already derived.
 ## Verifikasi
 - npx tsc --noEmit 0
 - bun test 804 -> still 0 fail (add pricing date test maybe)
 - manual: /cost shows `~N tokens (est.)` + `pricing verified 2026-09-09`; create file then `@` shows it without restart.

 # Prioritize batched reads (read_many_files) for turn efficiency
 ## Problem
 The model frequently calls `read_file` once per file when investigating, costing one
 round trip each. `read_many_files` already exists and batches 2-20 files in one call,
 but the guidance is weak: it is in `edit-plus` (not `core`), and the system prompt does
 not tell the model to prefer batching. Turns burn more steps than needed.
 ## Scope
 - Move `read_many_files` into the `core` tool set so it is always offered (even with
  minimal tool sets or a read-only variant).
 - Strengthen the per-tool guidance in `src/prompt.ts` TOOL_DOCS: `read_file` says
  "prefer read_many_files when you need several files"; `read_many_files` becomes the
  primary reading instruction with an explicit batch hint (2-20).
 - Add one "How to work" rule about reading efficiently (batch, grep/outline first,
  never read a file twice).
 - `deep` agent variant: add a read-batching instruction to its appendix.
 - Tests: assert `toolSetOf('read_many_files') === 'core'`; assert TOOL_DOCS contains
  the batching guidance; adjust any test asserting `read_many_files` is not core.
 - Docs: mention read_many_files as the default reading tool in docs/tools.md.
 ## Files touched
 - `src/tools.ts` — readManyFilesTool meta set: `'edit-plus'` → `'core'`.
 - `src/prompt.ts` — TOOL_DOCS lines + a workflow rule.
 - `src/agents.ts` — deep appendix line.
 - `test/session-features.test.ts` or `test/tools.test.ts` — set assertion.
 - `test/prompt.test.ts` — presence of batching guidance.
 - `docs/tools.md` — reading guidance.
 ## Verification
 - `bun run typecheck` clean.
 - `bun test` — full suite green (tool sets + prompt + deep agent tests).
 - `bun run build` compiles.
 ## Decision
 Batched reads save one round trip per extra file — the single highest-leverage
 efficiency win for investigation-heavy turns. Keep `read_file` (single-file reads,
 offset/limit, still needed for one file) but steer batching as the default once the
 file set is known.

 # Plan: kerjakan TODO.md — Now + Next + Maintenance
 ## Scope
 TODO.md status 2026-09-08:
 - Now/Summarize pruned span — KODE SUDAH ADA (prune.droppedSpan, session.summarizeDiscarded, retained note, budget 6k excerpt + 3-6 lines, 3 tests). Checkbox masih [ ]. Action: flip ke [x] + tambah test "pruned decision recoverable".
 - Now/Hot-reload — KODE SUDAH ADA (Session.updateSkills/updatePlugins + pendingSkills/pendingHost + drainPending + cli rebuild). Belum ada test mid-session callable. Action: tambah test + flip [ ].
 - Next/MCP without schema tax — BELUM. 20 tools ~2750 tok/req.
 - Next/Derive tool-name lists — BELUM. TOOL_SETS + MUTATING_TOOLS hand-list di tools.ts:877,913.
 - Next/Subagent parallelism — BELUM. task sequential.
 - Next/Undo a turn — BELUM.
 - Maintenance 4 items — pricing note, estimateTokens label, listPaths 5k stale, MUTATING derive.
 ## Urutan eksekusi (kecil dulu, besar belakangan, tiap langkah typecheck+test)
 1. **Now flip + tests** — patch TODO.md [x], test: hot-reload skill mid-session callable, pruned decision recoverable. Verifikasi: bun test.
 2. **Derive tool-name lists** — tandai mutating di definisi tool (tools.ts/tools-extra.ts/tools-git.ts/tools-net.ts), TOOL_SETS & MUTATING_TOOLS derive + test coverage. Risiko: silently ungated write jika lupa.
 3. **MCP tanpa schema tax** — DONE: phi 3 meta-tools mcp_list/mcp_inspect/mcp_call (mcpExpose=phi/direct/auto), prompt hanya nama server, permission+guard lewat built-in, keep direct registration untuk server 2-tool. Test: server 20-tool 0 schema sampai mcp_call (mcp.test.ts).
 4. **Subagent parallelism** — DONE: task `tasks` union + Promise.all fan-out (8 cap), panel per-subagent, test overlap waktu (subagent-parallel.test.ts).
 5. **Undo a turn** — snapshot file-tool edits pre-prompt (cap 100), /undo restores files+conversation atau keduanya, /redo, bash tidak ter-snapshot (docs), test edit reverted + record hilang.
 6. **Maintenance polish** — pricing source+date, estimateTokens label everywhere /cost, listPaths notice staleness / refresh, MUTATING derive dari #2.

 ## Verifikasi tiap langkah
 - bun run typecheck (exit 0)
 - bun test (790 -> bertambah, 0 fail)
 - manual: /registry add skill:xxx lalu task di next turn tanpa restart; /cost label; mcp_list cost
 ## Aturan
 - Spec dulu sebelum code (file ini).

 # Plan: 7 new features for shiro-neko
 Scope: add 7 features to the shiro-neko codebase. All touch `src/session.ts` and related
 files. Tests follow existing patterns (bun:test, MockLanguageModelV4, mkdtemp chdir).
 ## Features
 ### 1. Turn change summary (`/changes`)
 **Files:** `src/session.ts`, `src/commands.ts`, `src/ui/App.tsx`, `src/ui/panel-bodies.ts`, `test/changes.test.ts`
 Reuse undo snapshot infra: after turn, diff `turnBeforeFiles` vs `afterFiles`.
 - `Session.lastTurnSummary(): ChangeSummary | undefined` — returns `{ added: string[], modified: string[], deleted: string[] }` from the most recent snapshot's beforeFiles vs afterFiles.
 - Add `ChangeSummary` type exported from `src/session.ts`.
 - `/changes` command in `src/commands.ts` (type `'changes'`).
 - `changesPanel()` in `src/ui/panel-bodies.ts`.
 - Wire in `App.tsx` switch case + show after 'done' if files were changed.
 - Test: create files, write_file, assert summary has them; empty turn → undefined.
 ### 2. System prompt memoization
 **Files:** `src/session.ts`, `test/prompt-cache.test.ts`
 Version counters on volatile parts: `notebookVersion`, `memoryVersion`, `skillVersion`, `pluginVersion`, `toolVersion`.
 - `Session` stores a version map `{notebook, memory, skill, plugin, tool}`.
 - Bump versions: `onNotebookChange` already bumps notebook; memory.add/bump triggers callback; skills/plugins rebuilt → increment; tools rebuilt → increment.
 - Cache `{versionKey: string, text: string}` in Session.
 - `systemFor()` builds versionKey from all 5, returns cache hit if identical.
 - Expose `Session.promptCacheStats(): {hits: number, misses: number}` for /cost.
 - Test: two calls with same version → cache hit; bump one → miss.
 ### 3. Web search tool (`web_search`)
 **Files:** `src/tools-net.ts`, `test/tools-net.test.ts`
 Add `web_search` to `netTools` (same set as `web_fetch`, opt-in).
 - Backend: `config.search?.backend` (default `'duckduckgo-lite'`).
 - Implementation: fetch `https://lite.duckduckgo.com/lite/?q=<encoded>` → parse result HTML for title+url+snippet. No API key needed.
 - Max 5 results. Return as numbered markdown list.
 - `checkUrl` for safety on results, skip any that resolve private.
 - Description: "Search the web for information. Returns up to 5 results with titles, URLs, and snippets."
 - Export `NET_TOOL_NAMES` includes `web_search`.
 ### 4. `/search` — search saved sessions
 **Files:** `src/store.ts`, `src/commands.ts`, `src/ui/App.tsx`, `test/search.test.ts`
 Full-text grep over session transcripts on disk.
 - `store.searchSessions(query: string, limit?: number): SessionRecord[]` — case-insensitive substring match on `title` and serialized `messages[].content` (string only; JSON content stringified for matching).
 - `/search <query>` command (type `'search'`).
 - Returns panel with matching sessions: id prefix, title, first matched line.
 - Test: save session with specific content, search, assert match.
 ### 5. Workspace file refresh at turn boundary
 **Files:** `src/session.ts`, `src/cli.tsx` (minor), `test/workspace-refresh.test.ts`
 When `fileChangeSeq` bumps (files written this turn), re-walk workspace at turn end.
 - `Session.refreshWorkspaceFiles(): void` — re-runs `walk()` and updates `this.opts.workspaceFiles`. Only if `fileChangeSeq > lastWalkSeq`.
 - Track `lastWalkSeq` in Session.
 - Call in `send()` finally block, after `drainPendingHotReload`.
 - Expose `Session.setWorkspaceFiles(files)` for tests.
 - Test: start with empty workspace, write file via write_file, refresh, assert file appears.
 ### 6. Per-turn spend cap
 **Files:** `src/session.ts`, `src/config.ts`, `src/ui/panel-bodies.ts`, `test/spend.test.ts`
 - `maxSpendPerTurn?: number` in `SessionOptions` + `Config`.
 - In `send()`, snapshot `this.spend().usd` at turn start. At each step completion (after usage), check if spend delta exceeds cap → abort with notice.
 - `/cost` shows per-turn cap if set.
 - Config loading: `config.maxSpendPerTurn` optional number.
 - Test: mock model, set tiny cap, assert turn stops early.
 ### 7. `/fork` — fork session at a turn
 **Files:** `src/session.ts`, `src/commands.ts`, `src/ui/App.tsx`, `test/fork.test.ts`
 - `Session.fork(atIndex?: number): ModelMessage[]` — takes messages up to `atIndex` (default: before the last user message), returns deep-cloned copy. Does NOT modify current session.
 - `/fork` command (type `'fork'`) — forks to a new in-memory session with the cloned messages, preserving same options. Returns the new session's id.
 - For simplicity: `/fork` clones messages up to the second-to-last user message, pushes into a new session object, and reports the id. The user then `/resume` the forked session.
 - Test: build session with 3 turns, fork at -1, assert copy has 1 fewer user message.

 # Project-Driven Agent Workflow
 Status: spec
 Date: 2026-09-09
 ## Why
 The user wants shiro-neko agents to produce the same quality as this repo
 itself: docs-driven development, TODO.md + ROADMAP.md lifecycle, spec-first
 plans, complete unit tests, verify-before-done. Today the agent only reads
 AGENTS.md/CLAUDE.md/.shiro.md; it has no visibility of the project's task
 tracking, roadmap, or docs conventions, and nothing reminds it to keep them
 current.
 ## Scope
 - Prompt-level workflow policy (rendered in system prompt when enabled)
 - Boot loading of TODO.md + ROADMAP.md (compact, capped)
 - Lifecycle nudge: after a turn that wrote files without touching the task
  list, emit a soft reminder
 - `/workflow` command: show project workflow state
 - Config: `workflow.enabled` (default true), `workflow.docsDir` (default `docs/`)
 - Docs: docs/workflow.md + ROADMAP/TODO entries
 - Tests: prompt rendering, boot load, lifecycle nudge, config merge, /workflow
 ## Out of scope (explicitly not doing)
 - New tools (no permission surface, no storage)
 - Blocking / hard gates (agent stays in control; nudges only)
 - Auto-updating TODO.md (the agent does it via existing write tools)
 - Skill/plugin autoloading (existing system stays)
 ## Files touched
 - src/config.ts — `workflow?: { enabled?: boolean; docsDir?: string }` + merge arm
 - src/prompt.ts — WorkflowPolicy block in renderPrompt; depends on config
 - src/instructions.ts — load TODO.md + ROADMAP.md from git root; format compact
 - src/session.ts — SessionOptions.workflow config; after-turn nudge when
  fileChangeSeq bumped && no todo_write this turn
 - src/commands.ts — `/workflow` command (status summary)
 - src/cli.tsx — pass config; register /workflow
 - src/ui/App.tsx + panel-bodies.ts — /workflow panel
 - docs/workflow.md — new; ROADMAP.md, TODO.md updated
 - test/workflow.test.ts — new
 ## Design
 ### Config (config.ts)
 ```ts
 export type WorkflowConfig = {
  enabled?: boolean;   // default true
  docsDir?: string;    // default 'docs'
 };
 ```
 Merged in config.merge (same pattern as maxSpendPerTurn).
 ### Prompt block (prompt.ts)
 Rendered only when workflow.enabled !== false, and only when the project has
 TODO.md/ROADMAP.md/docs/ (so a bare repo gets no noise). Wording:
 ```
 Project workflow (this repo tracks its own progress). When the project has a
 TODO.md, read it before starting work and keep it current as you go:
 - mark done what you finished, and the sub-task you are on
 - add tests alongside code; the project expects complete unit tests
 - update ROADMAP.md when you ship a milestone
 - for anything non-trivial, write a short plan (spec-first) before code
 - verify with the project's check commands before declaring done
 ```
 Keyed in promptCache versions as `wf` so toggling the flag re-renders.
 ### Boot load (instructions.ts)
 `loadInstructions` also collects `<gitroot>/TODO.md` and `<gitroot>/ROADMAP.md`
 when present, capped (e.g. 6_000 chars each), rendered as:
 ```
 --- TODO.md (project task list) ---
 <first N lines, preserving section headers>
 ```
 Rendered AFTER instructions, BEFORE notebook/memory. So the agent always knows
 what the project is tracking before it starts.
 ### Lifecycle nudge (session.ts)
 After a turn's stream finishes (where fileChangeSeq is known): if
 `workflow.enabled !== false` AND the turn wrote files (fileChangeSeq bumped)
 AND the turn did NOT call todo_write AND the project has a TODO.md at the git
 root AND this is not the 1st turn (avoid nudge at boot): emit one `info` line
 via the normal notice mechanism:
 ```
 reminder: you modified files without updating the project task list (TODO.md).
 Keep it current: mark what you did.
 ```
 This is one soft line, not a stop; the run continues normally. Tracked as
 `workflowNudged` so it fires at most once per run (and once per session).
 ### `/workflow` command
 Status summary rendered in a panel:
 - workflow.enabled from config
 - TODO.md present? yes/no + line count
 - ROADMAP.md present? yes/no + line count
 - docsDir exists? yes/no
 - docs/ file count
 - tests: count of *.test.ts / *.test.tsx in tree (bounded)
 - nudged count this session
 ### Tests (test/workflow.test.ts)
 1. config merge: workflow.enabled + docsDir survive loadConfig merge
 2. prompt: workflow policy rendered when enabled + TODO present; absent when
   disabled or bare repo
 3. instructions: TODO.md + ROADMAP.md loaded from git root, capped
 4. lifecycle nudge: turn writes file, no todo_write -> info message once
 5. no nudge when todo_write was called
 6. /workflow command parses + panel renders

 # v9 — Provider prompt caching, registry trust, external hooks, /init scaffold, workflow plan nudge, nudge escalation, skill autoload
 Date: 2026-09-09
 Status: spec
 ## Why
 User asked what was missing; recommended: provider-side prompt caching (#1),
 registry trust (#3), external hooks (#4), `/init` TODO/ROADMAP scaffold (#5),
 workflow->plan skill nudge (#7), nudge escalation (#6). Structured diff
 review (#2) is **deferred**: the SDK's tool-approval model cannot express
 per-hunk approval, and it needs a rewrite hook that does not exist yet. This
 spec covers the six implementable items.
 ## Scope per item
 ### 1. Provider prompt caching (ROADMAP Next #1)
 Client-side memoization already makes the system prompt byte-identical across
 steps when nothing volatile changed. The remaining half: tell the provider to
 cache the stable prefix.
 - Anthropic: `cache_control: { type: 'ephemeral' }` on the system prompt
  block when the model is Anthropic. SDK supports
  `system: [{ type: 'text', text, cache_control }]`.
 - OpenAI: automatic prefix caching — nothing to send; skip.
 - Implement: `src/prompt.ts` splits the rendered system prompt into a stable
  prefix (everything before the volatile notebook/memory/skills suffix) and
  the volatile suffix; `session.ts` decides where to cut based on version
  counters. When only volatile parts changed (notebook/memory/etc), keep the
  stable prefix byte-identical and mark it cacheable; the volatile tail rides
  the same request but does not invalidate the prefix cache.
 - Provider routing: `Session` knows its model provider via `opts.modelId` /
  a `provider` option. Add `cacheSystemPrefix?: boolean` option; enable when
  provider is anthropic. SDK's own `cache_control` for Anthropic system
  arrays: `system: [...]` accepts per-block cache_control.
 - Tests: unit test that the splitter produces the same stable prefix across
  differing notebook versions; an Anthropic-format prompt carries
  `cache_control` on the stable block; OpenAI-format omits it.
 ### 3. Registry trust (ROADMAP Next)
 An index is trusted for its contents, not its authorship. Add publisher
 signature verification for registry entries:
 - `src/registry.ts` manifest gains optional `signature` + `signer` fields.
 - A pinned public key per publisher in config (`registry.publishers[<name>] =
  ed25519 pubkey`). Use Node's `crypto.verify` with ed25519 (Node ≥ 16 has
  `crypto.verify` for ed25519 via `createPublicKey`).
 - On install: when a manifest has `signature`, verify against the configured
  publisher key; mismatch → refusal naming the publisher and the expected key.
  When the manifest has no signature → refused with "unsigned; add the
  publisher key or install manually" unless `registry.allowUnsigned`.
 - Legacy manifests (no signature field) remain installable only with
  `allowUnsigned`; a signed one with an unknown publisher → refusal.
 - Tests: signature verifies; tampered body fails; unsigned refused unless
  allowUnsigned; unknown publisher refused.
 ### 4. External hooks (ROADMAP Later)
 Pre-tool hooks that can rewrite tool input, with a trust story like Codex:
 - `.shiro/hooks/` directory; each hook is an executable + a small manifest
  (`name`, `hook` = `pre_tool` | `after_turn` | ...; `tools` = `["*"]` or
  names).
 - On load, hash each hook file (sha256); first run, hash is shown and the
  user approves or denies (approval prompt). The hash is recorded in
  `~/.shiro-neko/hooks.json` (name → hash → approved). A hook whose hash
  changed since approval is refused until re-approved.
 - `pre_tool`: stdin gets `{tool, input, cwd}`, stdout gets
  `{"allow": true, "input": {...rewritten...}}` or `{"allow": false, "reason": ...}`
  or `{"blocked": "..."}`. A throwing/odd exit is treated as a block.
 - `after_turn`: stdin gets a turn summary; output ignored.
 - These extend `PluginHost.guard` (beforeToolCall) — a hook runs after the
  compiled plugins and before the permission check, so a hook cannot bypass
  the safety rules but can rewrite or refuse.
 - Cap: `hookTimeoutMs` default 5000; a hook that hangs is killed.
 - Tests: manifest parse; pre_tool rewrites input (default allow); pre_tool
  refusal blocks; unknown hook hash blocks until approved; after_turn runs;
  timeout kills a hung hook; a hook that returns garbage blocks.
 ### 5. `/init` scaffold TODO/ROADMAP/docs
 `/init` already writes AGENTS.md. Extend it to optionally scaffold the
 project-workflow files too:
 - `initPrompt` stays; after the agent writes AGENTS.md, if the repo lacks
  TODO.md/ROADMAP.md/docs and the user wants the scaffold, write:
  - `TODO.md`: `# TODO\n\nNow\n\nNext\n\nMaintenance\n\n`
  - `ROADMAP.md`: `# Roadmap\n\n## Next\n\n`
  - `docs/` empty dir (or a placeholder README)
 - CLI flag `/init` gains no new args; the agent's prompt gains the option.
  Headless: `--init-scaffold` flag writes the files directly (no model).
 - Tests: scaffold produces the three files when missing; does not overwrite
  existing ones.
 ### 6. Workflow nudge escalation
 Today: one nudge per session, then silence. Change to a gentle ladder:
 - Nudge 1: same as today.
 - Nudge 2 (if a later turn also writes without todo_update): "still no update
  to TODO.md; the project expects its task list kept current."
 - Nudge 3: final, "last reminder; update TODO.md when you have a moment."
 - Cap at 3 total (never infinite). `workflowNudged` → `workflowNudgeCount`.
 - Tests: third nudge is the last; count capped.
 ### 7. Workflow → plan skill autoload
 When the workflow policy renders (repo tracks progress), inject one extra line
 so the model knows the `plan` skill exists and to load it before non-trivial
 work:
 ```
 - before non-trivial work, load the `plan` skill (spec-first) and follow it
 ```
 - `workflowPolicy()` gains that line when enabled; test asserts it.

      models" fallthrough when the server errors. `current` sets the starting row, so a test names
      a preset rather than counting arrow presses.
 - [x] **`src/ui/PromptInput.tsx` (175 lines) now has a direct test — `test/prompt-input.test.tsx`.**
      It was already covered through `App` in `input.test.tsx` (history recall and stash, arrow and
      word motion, ctrl-u, ctrl-d, paste); what was left needed the component on its own, so this
      renders it directly with a controlled `Harness`. Fifteen cases cover the caret rendering (a
      bare focused caret, a blurred input with none, the placeholder inverting its first character
      only while focused, the cursor sitting under the character it points at), the kill keys
      (ctrl-a/ctrl-e, ctrl-k, ctrl-w, including a single word emptying the line), the `mask` (hidden
      value and the caret after a deletion), `onKey` swallowing a key before the input sees it while
      declining others, `initialCursor`, an external `value`, submit, and insert-at-cursor. Two
      expected frames were probed against the real renderer rather than assumed: a whitespace-only
      `Text` trims to `''`, and a mask renders the caret *after* the stars.
 - [x] **`src/ui/panel-bodies.ts` (78 lines) now has a direct test** — `test/ui-bodies.test.tsx`,
      shared with `buses.ts`. The four panels are pure functions of session and hook state, so
      they run without mounting Ink: the tools panel (sets named, a read-only agent narrowing it,
      the offered/registered hint), the cost panel (priced turn, unpriced model, the subagent line
      priced against its own model, the ceiling line), the context panel's empty branch, and the
      todos panel fed through the real `todo_write` tool.
 - [x] **`src/ui/buses.ts` (75 lines) now has a direct test.** `createNoticeBus` and
      `createSubagentBus` are covered: a pre-bind emit is queued and delivered in order on bind, a
      post-bind emit passes through, and a rebind takes over without replaying the queue.
      `applySubagentEvent` gains the cases the existing `ui-panels` test left open — a result
      attaching to its step, a mismatched or duplicate result being ignored, end/error status
      flips, an unknown id being a no-op, and two agents interleaving without crossing steps.
 - [ ] **13 `as any` casts across 11 test files.** Down from 29 across 17. The identical mock
      `usage` object (`{ inputTokens: {...}, outputTokens: {...} } as any`) is still repeated
      across several 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**

 ## [1.0.1]
 ### Added
 - **Rendered, resumed history.** A session restored with `-r`/`-c` or `/resume` now shows
  its saved conversation as real transcript lines instead of a blank prompt, converting the
  stored wire messages (user, assistant, tool calls and their results) into the same view the
  live loop paints.
 - **`/undo` and `/redo`.** Every prompt snapshots the files on disk first (capped near the last
  100), and `/undo` restores files, trims the conversation, or both. `/redo` reverses it. A
  `bash` command's side effects are not files and cannot be rolled back, which is stated in the
  command output rather than hidden.
 - **Parallel subagents.** The `task` tool accepts several independent investigations under a
  `tasks` array and runs them on separate context windows at the same time, joining their
  reports. A single call behaves exactly as before.
 - **Lazy MCP tools.** By default an MCP server now contributes three meta-tools (`mcp_list`,
  `mcp_inspect`, `mcp_call`) instead of one schema per server tool, so a server exposing twenty
  tools stops costing ~2750 tokens per request until one is actually called. Set
  `"mcpMode": "eager"` to register every server tool up front. Named servers are still listed
  in the prompt, and calls route through the same permission rules and guard as before.
 - **Hot-reloaded skill installs.** A skill installed from `/registry` mid-session is callable
  on the next turn without a restart (the `skill` tool reads its list live, so even the first
  install works). Plugins and external tools still need a restart because they join the guard
  chain and tool registry built once at boot.
 ### Fixed
 - A resumed session rendered an empty transcript. Loading a saved session populated the wire
  messages but never rebuilt the on-screen history, so after `-r`/`-c` or `/resume` the talk
  was blank even though the session data was there.
 - The walk behind `@file` completion refreshed only once per session; it now re-walks on a slow
  cooldown so a file created after the first `@` shows up within a short window.
 - A handful of plugin write tools were mutating but not gated by the permission defaults; the
  tool set and the mutating list are now derived from a single `mutating()` marker, so a tool
  can no longer be added to one and forgotten in the other.

 ### Session-feature batch (post-1.0)
 **`/changes`** — diff the last turn's file snapshot: added / modified / deleted, per
 absolute path. The file side of `/undo` without undoing; bash effects are still out of
 reach of either.
 **System-prompt memoization** — version counters (notebook, memory, skills, plugins,
 tools, workspace) gate a cached system prompt, so the string built on every step becomes

 **Workspace list refresh** — the boot-injected file list re-walks at a turn boundary when
 that turn wrote files, so a path created mid-session shows up in the next prompt without a
 restart.
 **Per-turn spend cap** (`maxSpendPerTurn`) — a `deep` turn that runs away is stopped at a
 step boundary by its own budget, complementing the session ceiling.
 **`/fork`** — clone the session at the last turn boundary into a new saved session;
 trying a different approach no longer costs the original.
 **Project-driven workflow** — when a repo tracks its own progress (TODO.md,
 ROADMAP.md, docs/), the agent carries a workflow policy in its system prompt:
 read the task list first and keep it current, spec-first for non-trivial work,
 complete unit tests, verify before done. TODO.md/ROADMAP.md ride along as
 `Project tracker` instruction blocks. A soft once-per-session nudge reminds an
 agent that edited files without updating the task list. `/workflow` shows the
 state; `workflow.enabled` / `workflow.docsDir` configure it. See
 [docs/workflow.md](docs/workflow.md).

 ## What the other agents have
 Surveyed opencode, Claude Code, Codex CLI, and phi against this tool's feature set. The point of
 the table is to record what is *worth copying* and what is worth *declining*, not to chase parity:
 each of these four spent effort here deliberately, and several of their choices are load-bearing for
 a reason that applies to us.
 The four are not the same shape. **Claude Code** and **Codex** are first-party CLIs tied to one
 vendor's models; **opencode** and **phi** are open-source and provider-agnostic, and opencode in
 particular is the closest thing to a peer here. Where a feature exists, the notes say what it costs
 — several are cheap to copy, and three are not.
 ### Where the four agree
 Six features have converged across all or nearly all of them. Convergence is the strongest signal
 available that a feature is not a fad — and the gaps in the table are as informative as the checks,
 because they show which features are genuinely optional and which are table stakes.
 | Feature | opencode | Claude Code | Codex | phi | Here |
 | --- | --- | --- | --- | --- | --- |
 | Per-pattern permission rules | `permission.bash` globs | `settings.json` allow/deny/ask | `approval_policy` + rules | Gate + `permissions.mode` | **shipped** |
 | Subagents with fresh context | `mode: subagent` | `agents/*.md` | — | sub-agents | **shipped** |
 | Markdown-defined agents | `agents/`, `commands/` | `agents/`, `skills/` | `AGENTS.md` | `.phi/` | **shipped** |
 | Session resume | `--session`, `--continue` | `--resume`, `--continue` | resume + rollout files | `sessions` | **shipped** |
 | Compaction | auto + `/compact` | `/compact`, `/rewind` summarize | compact prompt file | — | **shipped** |
 | Undo / rewind | `/undo`, `/redo` (via git) | `/rewind` (snapshots) | — | — | **missing** |
 Two of the six are outright missing from one or more tools, and undoing is missing from two of the
 four — so it is a real feature, not table stakes, and the two that have it disagree about how. The
 permission model here is not behind: it already carries the per-pattern rules, the credential deny,
 and the repeat guard the others arrived at, and `doom_loop` (below) is the one refinement worth
 taking. **Undo is the single converged feature genuinely absent**, which is why it leads Next.
 ### Detail worth having, by tool
 **opencode** — the closest peer, and the source of the permission shape already adapted here.
 `/undo` and `/redo` revert file changes **through git**, so they require the project to be a git
 repository; this is a real limitation, not an implementation detail, and it means an undo is only
 as good as the working tree's state. Agents are `primary` (build, plan) or `subagent` (general,
 explore, scout), switchable with Tab or `@`-mention, configured in `opencode.json` or Markdown
 frontmatter. A subagent runs in a **child session** with its own navigation keybinds
 (`session_child_first`, `session_parent`), and `subagent_depth` (default 1) caps nesting. Notable:
 `doom_loop` is a first-class permission key that fires when the same tool call repeats three times
 with identical input — the repeat guard here is an approval rule; theirs is a named primitive with
 its own recovery prompts. Sessions share over a URL (`/share`), which is a hosted product decision,
 not a local one.
 **Claude Code** — the most complete implementation of undo, and worth reading before building one.
 Checkpointing snapshots **before every user prompt**, keeps the **100 most recent** checkpoints,
 and stores them with the conversation so `/rewind` survives a resume. The rewind menu offers five
 distinct actions, and the split is the interesting part: *restore code*, *restore conversation*,
 *restore both*, *summarize from here*, *summarize up to here*. That is undo and compaction sharing
 one control surface. The honest limits are documented rather than hidden: only `Write`/`Edit`/
 `NotebookEdit` are tracked, `bash` side effects are not, **subagent edits are not captured** unless
 the skill ran in the foreground with `context: fork`, and symlinked or hard-linked files are
 skipped with an explicit warning. Their hook surface is the largest of the four — see *External
 hooks* under Later, which is where that capability belongs here.
 **Codex** — the sandbox is the differentiator, and it is genuinely hard to copy. Apple Seatbelt on
 macOS, Landlock + seccomp on Linux, and a restricted-token/AppContainer mechanism on Windows, with
 `workspace-write` the default and network **off** unless `sandbox_workspace_write.network_access`
 is set. `approval_policy` is now `on-request | never | { granular = {...} }` — `untrusted` was
 **retired** and can prevent the client from starting. Also shipped and worth knowing:
 `approvals_reviewer = "auto_review"` routes an approval prompt through a *reviewer subagent*
 rather than the user. `AGENTS.md` resolves global → project root → cwd, one file per directory,
 `AGENTS.override.md` winning, capped by `project_doc_max_bytes` (32 KiB default).
 **phi** — small (Go, ~12 MB), and the two ideas most worth stealing. First, **MCP without context
 death**: server tool schemas never enter the prompt; the system prompt lists only **server names**,
 and the model uses three meta-tools — `mcp_list`, `mcp_inspect`, `mcp_call` — with subprocesses
 starting lazily on first use. This is the concrete design behind *MCP without the schema tax*
 under Next. Second, the
 hook contract is the cleanest of the four: `pre_tool` runs **before** the permission gate and can
 `allow`, `deny`, or **`modify`** the input; `post_tool` can append model-facing `context` or
 rewrite `output`. Exit code `2` is a hard deny; `fail_closed` decides crash behaviour; in
 `readonly` mode only `fail_closed` hooks run, so a slow audit hook cannot stall exploration.
 ### Corrections to what this file said before
 Two claims previously written here were incomplete, and the research fixes them:
 - **Input-rewriting hooks are not phi's alone.** Codex ships it too: `PreToolUse` returns
  `permissionDecision: "allow"` with `updatedInput` to rewrite a call, verified in their docs and
  in `codex-rs/.../mcp.rs` (`with_updated_hook_input`). Two independent implementations make this
  the standard shape rather than one project's quirk — which raises its priority, and means the
  compiled plugin interface here is now the odd one out.
 - **Codex's hook trust is exactly as described, and the mechanism is now known.** Non-managed
  hooks cannot run until reviewed: Codex persists a `trusted_hash` in `config.toml`, records trust
  against the hook's **current hash**, and marks new or changed hooks for review in `/hooks`.
  `--dangerously-bypass-hook-trust` skips it for one invocation. The known hole is instructive: a
  reviewer on their PR noted that **replacing the script a hook points at does not reset trust**,
  because only the config is hashed. A trust story that hashes the declaration but not the artefact
  is a partial one — worth designing past rather than copying.
 ### What is worth declining
 Three of their features are deliberate here, and the survey confirms the reasoning:
 - **A client/server split** (opencode's OpenAPI server + TUI-as-client + IDE/web clients) exists to
  serve *second clients*. No second client is wanted here.
 - **LSP integration** — the quote already cited in Declined is accurate and now verified in full:
  opencode's own LSP page says it "is useful in some projects, but it is not always a net positive,"
  that servers "can get out of sync, use significant memory, vary by version or project, and slow
  down agent workflows," and that "in many projects it is better to have the agent run lint,
  typecheck, or other diagnostic CLI tools directly." They ship 30+ built-in servers and still say
  this. That is the strongest possible endorsement of the position in Declined.
 - **Session sharing over a URL** (opencode `/share`) is a hosted-service feature and brings a
  privacy surface this tool has no reason to take on.

 ### Prompt caching
 The system prompt is now memoized client-side, so the string is byte-identical across
 steps when nothing volatile changed. The remaining half is provider-side: Anthropic
 `cache_control` and OpenAI automatic prefix caching already reward that stable prefix, and
 splitting the stable prefix from the volatile suffix (notebook/memory) would make the
 cache unmissable even when a todo_write happens mid-turn.

 decision, and there are no signatures. Publisher keys and a pinned digest per entry would make

 ### Auto-review an approval
 Codex ships `approvals_reviewer = "auto_review"`: an eligible approval prompt is routed through a
 reviewer **subagent** instead of surfacing to the user, using the same sandbox boundary. `explore`
 and `review` already exist and are read-only, so the piece to build is a reviewer persona that
 decides an approval request and a policy that says which prompts are eligible — a batch of three
 identical `git status` calls should not each interrupt, but a first `rm` should. The failure mode
 to design against is a reviewer that waves through exactly what the user would have stopped, so it
 must be opt-in, name itself when it approves, and never override a deny rule.
 ### Name the repeat guard
 opencode has `doom_loop` as a first-class permission key: it fires when the same tool call repeats
 three times with identical input, carries its own recovery prompts, and is configurable per agent.
 The equivalent here is a rule inside the permission layer — the call repeated identically three
 times in one turn asks even when allowed — which works but is unnamed, unconfigurable, and
 invisible in `/tools`. Promoting it to a named primitive makes it inspectable and lets an agent
 tighten or loosen it, and the recovery prompt is the part genuinely missing: a loop is better
 interrupted with advice than with silence.

 `--no-mcp` skips them all, which is also the quickest way to tell whether a slow start is MCP
 or something else.
 ## How a server's tools reach the model
 Two modes, switched with `"mcpMode"` in config. **`lazy` is the default**; `eager` is the opt-in.
 - **Lazy** registers three meta-tools — `mcp_list`, `mcp_inspect`, `mcp_call` — instead of one
  schema per server tool. The server's real tools are fetched only when `mcp_call` actually
  invokes one, so a server exposing twenty tools costs almost nothing until one is used. This
  is why the affordability paragraph in the README says a configured server no longer taxes
  every request.
 - **Eager** registers every server tool up front as in the old 1.0 behaviour. If a server
  exposes only two tools, eager is cheaper because there is no list-then-inspect round trip.
 The model is told the connected server names through the meta-tool descriptions and a prompt
 line, then discovers each tool's schema on demand:
 ```
 - mcp_list, mcp_inspect, mcp_call: MCP tools are fetched on demand. mcp_list names a
  server's tools, mcp_inspect reads one tool's schema, mcp_call runs it. Never guess a
  server or tool name: list first.
 ```
 A `mcp_call` still routes through the same permission rules and guard as a built-in, so the
 lazy path is not a way around approval.

 ## The approval model
 Every call resolves to `allow`, `ask`, or `deny` through a rule matched against the call's
 subject — the command for `bash`, the path for a file tool. [Permissions](permissions.md) is the
 full reference; the short version:
 **Allowed by default.** Read-only tools and anything touching the agent's own state:
 `read_file`, `read_many_files`, `glob`, `grep`, `list_dir`, `task`, the whole git set,
 `todo_write`, `remember`, `recall`, `forget`, `skill`, `ask`, and anything a plugin marks
 auto-approved.
 **Denied by default.** `*.env`, `*.env.*`, and `*.pem` on read. Not gated, refused: a secret that
 reaches the context is on the wire and in the session file, and there is no taking it back.
 `*.env.example` is allowed.
 **Asked by default.** `write_file`, `edit_file`, `multi_edit`, `apply_patch`, `move_file`,
 `delete_file`, `bash`, `bash_stop`, `web_fetch`, and every `mcp__*` tool.
 ```
 bash wants to run
 git status --porcelain
 y allow once | a always allow bash git * | n deny
 ```
 `a` whitelists the **pattern**, not the tool: approving `git status` runs `git log` unprompted and
 still asks about `npm publish`. `n` tells the model it was denied and to ask what to do instead.
 A rule turns the common cases off entirely:
 ```json
 { "permission": { "bash": { "*": "ask", "git *": "allow", "bun test*": "allow" } } }
 ```
 Three more things sit around the rules:
 - **The guard plugin refuses first.** It is not an approval, and `--yolo` does not reach it. See
  [plugins](plugins.md).
 - **A repeated call asks anyway.** The same tool with identical input three times in one turn stops
  for approval even when allowed — a model repeating itself is not making progress.
 - **The SDK enforces the decision.** A denied call provably never executes, because the SDK never
  reaches the tool's `execute`. A tool cannot forget to honour a denial. See
  [architecture](architecture.md#why-approval-goes-through-the-sdk).
 ## Tool sets
 Each tool costs its name, its description, and its JSON schema on **every request**. The current
 registry has forty-one built-ins. `/tools` shows the live set; disabling an optional set removes
 its schemas from both the request and the system prompt.
 | Tool | Bytes | Tool | Bytes |
 |---|---|---|---|
 | `read_many_files` | 972 | `git_blame` | 499 |
 | `multi_edit` | 934 | `git_log` | 484 |
 | `edit_file` | 618 | `git_diff` | 473 |
 | `grep` | 595 | `bash` | 466 |
 | `list_dir` | 594 | `git_show` | 432 |
 | `read_file` | 526 | `git_status` | 292 |
 | `glob` | 499 | `write_file` | 289 |
 Selection accuracy also falls as the list grows: a model choosing between six tools picks better
 than one choosing between twenty.
 Sets let you switch off what a project does not need:
 | Set | Tools | Cost |
 |---|---|---|
 | `core` | `read_file` `read_many_files` `write_file` `edit_file` `glob` `grep` `bash` `bash_status` `bash_stop` | ~3,200 B |

 ```json
 { "toolSets": ["edit-plus"] }
 ```
 Omit `toolSets` for the default sets. Add `net` when the agent should fetch public pages.
 `core` is always on — without read, edit, and bash the agent is not an agent. A disabled set reaches neither the wire nor the system prompt, since
 a prompt that names an absent tool teaches the model to attempt calls that cannot succeed.
 Session, plugin, and MCP tools are not part of this budget and are never gated here.
 An unrecognised set name is dropped silently. The header line at startup shows which sets
 actually loaded, so a typo reads as "that set is off" rather than as an error — worth checking
 if a tool you expected is missing.
 `/tools` shows which set each live tool came from:
 ```
 tools
 20 offered this turn of 22 registered
 - `bash`             core
 - `git_diff`         git
 - `list_dir`         edit-plus
 - `remember`
 ```
 A tool with no set is a session, plugin, or MCP tool.
 ### Which sets to keep
 Both extra sets earn their place in most projects, but not all:
 - **No git in the repo?** `git` is 2,180 bytes the model can never use. Switch it off.
 - **A model that handles many tools badly?** `{ "toolSets": [] }` trims to six, which is the
  smallest set that still lets the agent work.
 - **Reading a lot, editing rarely?** Keep `edit-plus` for `list_dir` and `read_many_files`
  alone; they pay for themselves in round trips saved.
 ## The `extra` set
 Twenty-one tools across five families, on by default. Each follows the same rules as the core
 tools: writes are jailed to the workspace, reads honour `.gitignore`, and every git call spawns
 the binary with a fixed argument array, never a shell string.
 ### Line edits
 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. |

 | `tree` | Indented directory tree, ignore-aware, directories first. A broad shape faster to scan than `list_dir`. |

 | `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.

 |---|---|
 | `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. |
 -prefixed block).
   This is the strongest source: it is written by the people who know what a cold agent
   should run.
 2. **package.json scripts** — `test`, `typecheck`, `check`, `lint`, `build` in that priority,
   then the rest alphabetically. The runner matches the lockfile: `bun run` when `bun.lock`
   exists, `npm run` otherwise.
 3. **Toolchain defaults** — what the project's own build system says verify means: `bun test`
   for a Bun project, `cargo test` for Rust, `go test ./...` for Go, `pytest` for Python.
 The `target` argument selects one suggestion by name (or `all`). Output is capped, runs are
 killed at the timeout (SIGTERM reported, not a clean exit), and a 3-iteration fix ceiling is
 baked into the system prompt's verify loop — a failing check gets fixed and re-run, but a
 check that keeps failing stops grinding and reports instead.
 Each candidate is gated by permission rules on its `target` name, the only part the model
 chooses.

 must not kill a dev server the user still wants.
 ### `bash` background mode (dev servers, watchers)
 A command that does not exit — `bun dev`, a watcher, a test suite that never returns — blocks
 the tool until its timeout, which looks like the agent is stuck. Set `background: true` instead:
 ```
 command:  bun dev
 background: true
 name:  dev server
 ```
 The tool returns immediately with a handle:
 ```
 background 1: running (pid 4821) — poll with bash_status handle=1, stop with bash_stop handle=1
 command: bun dev
 ```
 The command runs **detached** (its own process group), so it keeps running while the agent
 works, ctrl-c in the agent does not signal it, and the model can poll it and keep going:
 - **`bash_status`** `handle` — whether it is still running, its exit code when finished, and
  any output produced since the last status. Poll this while working.
 - **`bash_stop`** `handle` — kill it, awaited so the process really is gone.
 ```

 new output:

 Background commands are reaped when the agent exits (killed and removed), and anything left
 over from a crashed session is killed at the next boot, so a dev server an agent started cannot
 linger unnoticed. `/bash` lists what is running, `/bash stop <id>` and `/bash stop all` stop

 # Project-driven agent workflow
 Shiro Neko treats a repository the way this project treats itself: progress
 tracked in TODO.md and ROADMAP.md, docs-driven development, spec-first plans,
 complete unit tests, and verify-before-done. When the repo keeps those files,
 the agent's system prompt carries a short workflow policy and the session
 tracks whether the workflow is being followed.
 ## What the agent sees
 When the session starts in a git repo that has any of:
 - `TODO.md` at the git root
 - `ROADMAP.md` at the git root
 - a `docs/` directory (configurable with `workflow.docsDir`)
 the system prompt gains a "Project workflow" block:
 - read TODO.md (the task list) before starting and keep it current as you go
 - keep ROADMAP.md current when a milestone ships
 - write a short plan first (spec-first) for anything non-trivial
 - add tests alongside code; the project expects complete unit tests
 - verify with the project's check commands (tests/typecheck/build) before
  declaring done
 Bare repos (no TODO, ROADMAP, or docs) get no such block — the policy only
 renders when the project itself tracks progress, so a throwaway directory does
 not collect noise.
 ## Auto-scaffolding
 When you run shiro against an *existing* repo that has none of the tracking
 files (no TODO.md, no ROADMAP.md, no `docs/`, no AGENTS.md), the first turn
 bootstraps them automatically: the agent investigates the repo and writes
 project-specific TODO.md, ROADMAP.md, `docs/README.md`, and AGENTS.md before
 answering. A notice reports what was written:
 ```
 scaffolded project workflow files: TODO.md, ROADMAP.md, docs/, AGENTS.md
 ```
 - **Never overwrites.** Any existing tracker (TODO.md, ROADMAP.md, `docs/`, or
  AGENTS.md) at the git root means the repo already tracks itself — nothing is
  created or touched.
 - **Model-driven content.** The files use real project content (commands,
  layout, conventions verified against the code) like `/init` does for
  AGENTS.md. If the model call fails, it degrades to the empty-template
  scaffold so the turn is never interrupted.
 - **Write at the git root**, not the cwd — matches where the policy looks.
 - Runs **once per session**, before the first real turn, so the policy and the
  first nudge already see the files.
 - The manual `/init` command still exists for when you want to write AGENTS.md
  (and scaffold the trackers) on demand.
 TODO.md and ROADMAP.md are also loaded into the conversation like instruction
 files (`Project tracker (...)`), capped tighter than AGENTS.md so the agent
 sees the shape of the work without filling its context. This mirrors the
 existing `AGENTS.md` / `CLAUDE.md` / `.shiro.md` loading: outermost first, git
 root down to cwd.
 ## The nudge
 After a turn that wrote files (edit_file, write_file, apply_patch, ...) but
 never called `todo_write`, the session emits one soft notice:
 ```
 reminder: you modified files without updating the project task list (TODO.md).
 Keep it current: mark what you did.
 ```
 Design constraints:
 - **Once per session.** Repeating a nag trains the model to ignore it.
 - **Not a gate.** The agent stays in control; this is guidance, not a block.
 - **Only when the repo has a TODO/ROADMAP.** A repo that tracks nothing gets
  no reminder.
 - Suppressed when the turn already called `todo_write` — the task list is
  current, nothing to say.
 ## Configuration
 ```yaml
 workflow:
  enabled: true        # master switch; default true
  docsDir: docs        # where the project keeps developer docs; default 'docs'
  autoScaffold: true   # write TODO/ROADMAP/docs/AGENTS.md in a bare repo on first turn; default true
 ```
 `workflow.enabled: false` disables both the prompt policy and the nudge.
 `workflow.autoScaffold: false` disables only the auto-bootstrap (the policy and
 nudge still engage when the repo already tracks progress).
 ## /workflow
 `/workflow` renders a panel with the project's tracking state and the
 session's behaviour:
 | row | meaning |
 |---|---|
 | `workflow` | on/off from config |
 | `TODO.md` | present? line count |
 | `ROADMAP.md` | present? line count |
 | `docs dir` | present? file count (bounded at 200) |
 | `reminders sent` | whether this session nudged (once, ever) |
 ## Relationship to AGENTS.md
 AGENTS.md-style files are standing orders from the user and override the
 agent's defaults. The workflow policy is a default that documents what a
 repo tracking its own progress expects. When the two conflict, AGENTS.md
 wins — the workflow feature is a floor, not a ceiling.

Muhammad Zakir Ramadhan	4eafc064bf	fix release.yml: install bun in the publish job before composing notes The publish job runs make-release-notes.ts with bun but never installed it, so on a bare runner it failed with 'bun: command not found' and no release was ever published after the binaries were built.	2026-09-17 19:33:29 +07:00
Muhammad Zakir Ramadhan	8eebc0f4d6	release 1.0.1: fix resume showing a blank transcript A resumed session loaded its wire messages but never rebuilt the on-screen history, so -r/-c and /resume rendered a blank transcript. Convert the stored messages back into transcript lines and seed the panel with them at mount and after /resume.	2026-09-17 19:26:42 +07:00
Muhammad Zakir Ramadhan	052423556a	fix release.yml: pin bun-version literally so the workflow pin test passes The release workflow hoisted bun-version into an env var, but test/cli.test.ts asserts both workflows carry the literal 'bun-version: 1.3.14' pin. Revert the indirection - the pin is the point.	2026-09-17 18:15:02 +07:00
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.	2026-09-17 17:49:19 +07:00
