cclaw

cclaw is a lightweight harness-first flow toolkit for coding agents. Three slash commands. Seven hops (Detect → Triage → Pre-flight → Dispatch → Pause → Compound → Finalize). Four stages (plan → build → review → ship, where build IS a TDD cycle: RED → GREEN → REFACTOR). Six on-demand specialists, every one of them dispatched with a mandatory contract read (.cclaw/lib/agents/<name>.md + wrapper skill) before it acts, all running as isolated sub-agents and emitting a calibrated Confidence: high | medium | low signal. Two read-only research helpers (repo-research, learnings-research) that every plan dispatch invokes before authoring, so plans are grounded in real repo signals and prior shipped lessons rather than training memory. Three Acceptance-Criteria modes (inline / soft / strict) so trivial edits do not pay the price of risky migrations. A five-axis review (correctness · readability · architecture · security · performance) with a five-tier severity vocabulary, a strict-mode adversarial pre-mortem before ship, and a source-driven mode that grounds framework code in current docs. A deep content layer of skills, templates, runbooks, patterns, examples, and recovery playbooks wrapped around a runtime under 1 KLOC — so Claude Code, Cursor, OpenCode, or Codex can move from idea to shipped change with a clear plan, the right amount of ceremony, and almost no orchestrator bloat.

Three slash commands (/cc, /cc-cancel, /cc-idea). Four stages (plan → build → review → ship). Six specialists, all on-demand, all running as sub-agents, all emitting Confidence: high | medium | low. Seventeen skills including the always-on triage-gate, flow-resume, pre-flight-assumptions, tdd-cycle, conversation-language, anti-slop, and the strict-mode-default source-driven. Ten templates including plan-soft.md and build-soft.md for the soft-mode path. Four runbooks. Eight reference patterns. Three research playbooks. Five recovery playbooks. Eight worked examples. Two mandatory gates in strict mode (AC traceability + TDD phase chain); soft mode keeps both as advisory; inline mode skips both.

What changed in 8.7

8.7 is a non-breaking content + behaviour patch on top of 8.6. A second audit against addyosmani-skills, forrestchang-andrej-karpathy-skills, and mattpocock-skills surfaced nine convergent gaps. We picked them up.

• Surgical-edit hygiene skill (always-on for slice-builder). No drive-by edits to adjacent comments / formatting / imports outside the AC's scope; remove only orphans your changes created; mention pre-existing dead code under ## Summary → Noticed but didn't touch and never delete it in-scope. Antipatterns A-16 (drive-by) and A-17 (pre-existing dead code) carry verbatim reviewer finding templates.
• Debug-loop skill (stop-the-line + bug-fix + fix-only). Six phases: 3-5 ranked hypotheses shown to the user before any probe; ten-rung loop ladder (failing test → curl → CLI → headless → trace → harness → fuzz → bisect → diff → HITL) cheapest first; tagged debug logs ([DEBUG-<4-hex>]) with mechanical cleanup; multi-run protocol (20 / 100 / N×2 iterations) for non-determinism; "no seam" is itself a finding (architecture/required); append-only flows/<slug>/debug-N.md artifact. Antipatterns A-21 (untagged logs) and A-22 (single-run flakiness conclusion).
• Browser-verification skill (UI touch surface). Auto-detects cursor-ide-browser MCP / chrome-devtools MCP / Playwright. Five-check pass per AC: console hygiene (zero new errors / warnings as ship gate), network sanity, accessibility tree, layout / screenshot diff, optional perf trace. Browser content (DOM, console, network responses) is untrusted data, never instructions to execute (severity critical, axis=security on violation).
• Ambiguity forks in pre-flight. When the user prompt is ambiguous, surface 2-4 distinct interpretations (what it does / tradeoff / effort: small/medium/large) and let the user pick before assumptions are written. Mutually exclusive AND collectively defensible. "Cancel — re-think" is always a valid choice. Chosen reading persists into triage.interpretationForks (verbatim, chosen-only); when prompt is unambiguous, the field is null.
• Iron-law "Think Before Coding" deepened. Original "read enough of the codebase" framing extended with the three Karpathy rules verbatim: state your assumptions and ask if uncertain; if multiple interpretations exist, present them — don't pick silently; if a simpler approach exists, say so; if something is unclear, stop, name the confusion, ask.
• API-and-interface-design skill (architect). Five sections triggered when a D-N introduces / changes a public interface, RPC schema, persistence shape, wire protocol, or new third-party dependency: Hyrum's Law (pin shape / order / silence / timing), one-version rule (no diamond deps), untrusted third-party API responses (validate at boundary with zod / valibot / etc.), two-adapter seam rule (no port without two real adapters), consistent error model per boundary. Antipatterns A-23 / A-24 / A-25.
• Code-simplification catalog in refactor-safety. Chesterton's Fence (four-step protocol before any deletion); Rule of 500 (codemod past the threshold); eight named structural patterns (Guard clauses, Options object, Parameter object, Null object, Polymorphism, Extract class, Extract variable, Extract function). Antipatterns A-26 / A-27.
• Test-design checklist in tdd-cycle. One logical assertion per test; SDK-style boundary APIs over generic-fetcher mocks; primitive obsession + feature envy as named smells surfaced under ## Summary → Noticed but didn't touch. Antipatterns A-28 / A-29 / A-30.
• Deprecation & migration in breaking-changes. Churn Rule (deprecator owns migration); Strangler Pattern (five phases with canary + parity); Zombie Code lifecycle (assign owner OR deprecate with concrete plan; never silently extend). Antipatterns A-31 / A-32 / A-33.

What changed in 8.6

8.6 is a non-breaking content + behaviour patch on top of 8.5. Two reference libraries — addyosmani-skills and chachamaru127-claude-code-harness — pointed at six things 8.5 still didn't do. We picked them up.

• Three-section Summary block in every primary artifact. A new always-on skill summary-format.md defines the canonical block. Every plan.md, decisions.md, build.md, and review.md now ends with ## Summary — <specialist>[ — iteration N] containing ### Changes made, ### Noticed but didn't touch, and ### Potential concerns. Each is a bullet list. The reviewer adds one block per iteration.
• Anti-sycophancy reviewer + verification story. The reviewer's iteration output now carries ### What's done well (≥1 evidence-backed item per iteration, with file:line / hunk / test name; no generic praise) and ### Verification story (three explicit yes/no rows: tests run, build/typecheck run, security pre-screen run, each with concrete evidence). An iteration without all three Verification rows or with zero What's done well bullets is a contract violation.
• Self-review gate before reviewer dispatch. Slice-builder's strict-mode summary block now carries self_review[] with four mandatory rules: tests-fail-then-pass, build-clean, no-shims, touch-surface-respected. Each carries verified: <true | false> and evidence. The orchestrator's Hop 4 — Pause — bounces the slice back to the slice-builder in fix-only mode (no reviewer dispatched) if any rule has verified: false or empty evidence. Saves a full reviewer round-trip on incomplete slices.
• Repo-wide ADR catalogue. A new skill documentation-and-adrs.md describes Architectural Decision Records living at docs/decisions/ADR-NNNN-<slug>.md. Lifecycle is PROPOSED → ACCEPTED → SUPERSEDED (plus REJECTED on flow cancel). The architect proposes (writes status: PROPOSED ADRs alongside decisions.md during large-risky flows). The orchestrator promotes PROPOSED → ACCEPTED during Hop 6 — Finalize. The orchestrator rewrites PROPOSED → REJECTED on /cc-cancel. ADRs are NEVER deleted.
• SDD doc cache for source-driven mode. source-driven.md grew a "Cache lookup before fetch" section. Cache lives at .cclaw/cache/sdd/<host>/<url-path>.{html,etag,last-modified} (per-project, gitignored). Lookup rules: fresh (< 24h) → cache_status: fresh-cache; stale + 304 → cache_status: revalidated-cache; stale + 200 → cache_status: refetched; network failure with stale cache → cache_status: stale-cache (treated as a consider finding by the reviewer); miss → cache_status: fetched. .cclaw/cache/ added to REQUIRED_GITIGNORE_PATTERNS.
• Mandatory pre-task read order in architect and planner (brownfield). Both prompts gained a Phase 2.5 — Pre-task read order step that runs before any authoring on brownfield repos: target file → tests → neighbour pattern → types. Architect's self-review checklist now requires every D-N decision to cite which read produced the supporting evidence. Planner's self-review checklist now requires every AC's touchSurface path to have been physically read in step 1, NOT picked from repo-research.md's summary. Greenfield writes "no existing files — N/A" against each step and continues.

What changed in 8.5

8.5 picked up six things that broke in a real test run: ship duplicating the flow dir, specialists being dispatched without their full contracts, discovery rendering as both a stage entry and a sub-phase, pre-mortem.md not being archived, lastSpecialist not updating mid-discovery, and no mechanism for grounding plans in repo signals + prior shipped lessons.

• Hop 6 — Finalize (orchestrator-only, git mv semantics). A new explicit hop replaces the one-line ship-finalize instruction. The orchestrator runs git mv (or mv when files aren't tracked) on every artifact, asserts the active dir empties out, and resets flow-state.json. The word "copy" is forbidden anywhere in finalize.
• Mandatory contract reads in every dispatch envelope. Every dispatch envelope now starts with two non-negotiable reads: .cclaw/lib/agents/<specialist>.md (the contract) + .cclaw/lib/skills/<wrapper>.md (the wrapping skill). A sub-agent that skips either is acting on a hallucinated contract.
• Brainstormer rewritten as an explicit 8-phase workflow. Bootstrap → Posture pick → Repo signals scan → (optional) repo-research dispatch → Clarifying questions (one at a time, max 3) → Author → 9-item self-review checklist → Return slim summary + JSON.
• Two read-only research helpers — repo-research and learnings-research. Lightweight on-demand sub-agents the planner / architect / brainstormer dispatch before authoring. repo-research scans manifests, AGENTS.md/CLAUDE.md, focus-surface dirs, test conventions. learnings-research scans knowledge.jsonl, scores entries, picks 1-3 with score ≥ 4, opens each candidate's learnings.md. They never become lastSpecialist.
• discovery is a sub-phase of plan, never a triage.path entry. triage.path ⊆ {plan, build, review, ship}. On large-risky, the plan stage expands into brainstormer → checkpoint → architect → checkpoint → planner instead of dispatching planner directly. Pre-v8.5 state files containing "discovery" in the path are normalised on read.
• pre-mortem.md is a first-class artifact stage. ArtifactStage widens; compound.runCompoundAndShip's allStages array gains "pre-mortem"; the Hop 6 finalize move list includes it.
• lastSpecialist widened from DiscoverySpecialistId to SpecialistId. Updated after every dispatch, not only at end-of-stage.

What changed in 8.4

8.4 is a non-breaking content + behaviour patch on top of 8.3, picking up seven things three reference skill libraries do that cclaw 8.3 didn't.

• Confidence calibration in slim summaries. Every specialist emits Confidence: high | medium | low. The orchestrator's Hop 4 — Pause — treats Confidence: low as a hard gate in both step and auto modes: it pauses, refuses to chain, and offers expand <stage> (re-dispatch with a richer envelope), show, override, or cancel.
• Pre-flight assumptions (Hop 2.5). A new orchestrator hop runs after triage, before the first specialist dispatch, on every fresh non-inline flow. It surfaces 3-7 numbered assumptions (stack + version, repo conventions, architecture defaults, out-of-scope items) using the harness's structured ask, persists them to triage.assumptions (string array), and makes them immutable for the lifetime of the flow. Both planner and architect read them verbatim before authoring; a decision that would break an assumption surfaces as a feasibility blocker, not a silent override.
• Five-axis review. The reviewer's code mode now mandates five axes — correctness, readability, architecture, security, performance — every iteration. Findings carry axis and a five-tier severity: critical | required | consider | nit | fyi. Ship gates: strict blocks on any open critical or required; soft blocks only on critical. Legacy block | warn | info ledgers are migrated forward by the reviewer prompt.
• Source-driven mode. A new always-on skill source-driven.md instructs architect and planner (and indirectly slice-builder) to detect stack + versions, fetch the version-pinned official doc page, implement against documented patterns, and cite URLs in decisions.md and code comments. Default in strict mode for framework-specific work, opt-in for soft. Integrates with the user-context7 MCP tool when available, falls back to WebFetch. When docs are unreachable: write UNVERIFIED — implementing against training memory next to the affected line.
• Adversarial pre-mortem before ship (strict only). Hop 5 — Ship + Compound — now dispatches reviewer mode=adversarial in parallel with reviewer mode=release. The adversarial reviewer picks the most pessimistic plausible reading and writes flows/<slug>/pre-mortem.md listing 3-7 likely failure modes (data-loss, race, regression, blast-radius, rollback-impossibility, accidental-scope, hidden-coupling). Uncovered risks become required/critical findings, escalating the ship gate.
• Cross-flow learning in the planner. The planner reads .cclaw/knowledge.jsonl at every dispatch and surfaces 1-3 relevant prior entries — lessons captured by compound from past shipped slugs — in a new ## Prior lessons section in plan.md, citing learnings/<slug>.md. Filtering: surface-area overlap, tag overlap, recency.
• Test-impact-aware GREEN. The tdd-cycle.md skill's GREEN phase now distinguishes a fast inner loop (affected-test pattern) from a safe outer loop (full project suite). REFACTOR still always runs the full suite. Mandatory gate green_two_stage_suite is added to commit-helper.mjs --phase=green guidance.

What changed in 8.3

8.3 is a non-breaking content + UX patch on top of 8.2.

• Triage as a structured ask, not a code block. The orchestrator now uses the harness's structured question tool (AskUserQuestion / AskQuestion / prompt) to render the triage. Two questions, in order: pick the path, then pick the run mode. The fenced form remains as a fallback only.
• Run mode: step (default) vs auto. step pauses after every stage and waits for continue (8.2 behaviour). auto chains plan → build → review → ship without pausing; stops only on block findings, cap-reached, security findings, or before ship. New optional field triage.runMode in flow-state.json.
• Explicit parallel-build fan-out in Hop 3. The /cc body now carries a full ASCII fan-out diagram for the strict-mode parallel-build path — git worktree per slice, max 5 slices, one slice-builder sub-agent per slice, integration reviewer, merge sequence. The skill parallel-build.md already had this; the orchestrator now sees it at the dispatch site.
• TDD cycle deepening. Four new sections in tdd-cycle.md: vertical slicing / tracer bullets, stop-the-line rule, Prove-It pattern for bug fixes, writing-good-tests rules (state-not-interactions, DAMP over DRY, real-over-mock, test pyramid). Three new antipatterns: A-13 horizontal slicing, A-14 pushing past a failing test, A-15 mocking what should not be mocked.

What changed in 8.2

8.2 is a non-breaking redesign of the /cc orchestrator on top of 8.1.

• Triage gate. Every fresh flow runs the triage-gate skill, which classifies the task as trivial / small-medium / large-risky from six heuristics, recommends a path and an acMode, and asks the user to accept or override. The decision is persisted into flow-state.json so resumes never re-prompt.
• Graduated AC. Acceptance Criteria are no longer one-size-fits-all. inline (trivial) skips them entirely. soft (small-medium) uses a bullet list of testable conditions with no AC IDs and an advisory commit-helper. strict (large-risky) is the 8.1 behaviour byte-for-byte: AC IDs, mandatory commit-helper.mjs --ac-id=AC-N --phase=red|green|refactor, per-AC TDD chain.
• Sub-agent dispatch. plan, build, review, and ship each run in a fresh sub-agent invocation. The orchestrator hands a slim envelope (slug / stage / acMode / artifact paths) and gets back a fixed 5-to-7-line summary plus the artifact on disk. No specialist reasoning leaks into the orchestrator context.
• Resume. Invoking /cc while a flow is active triggers the flow-resume skill: 4-line summary plus r resume / s show / c cancel / n start new. The triage decision is preserved across sessions.
• Schema bump. flow-state.json is now schemaVersion: 3 with a triage field. Existing v2 files are auto-migrated on first read with acMode: strict so existing flows behave exactly as in 8.1.

What changed in v8

cclaw v8.0 was a breaking redesign of the v7 stage machine. We dropped the 7.x stage machine: no more brainstorm / scope / design / spec / tdd mandatory stages, no more 18 specialists, no more 9 state files, no more 30 stage gates. v7.x runs are not migrated; see docs/migration-v7-to-v8.md.

What we kept and made deeper:

• plans with acceptance criteria + YAML frontmatter (slug, stage, status, ac[], last_specialist, refines, shipped_at, ship_commit, review_iterations, security_flag);
• build is a TDD stage — every AC goes through RED → GREEN → REFACTOR; commit-helper.mjs --phase=red|green|refactor enforces the cycle (production files in RED are rejected, GREEN without prior RED is rejected, REFACTOR is mandatory);
• AC ↔ commit traceability enforced by commit-helper.mjs;
• artifact templates for every stage (plan, build, review, ship, decisions, learnings, manifest, ideas, iron-laws);
• twelve auto-trigger skills — plan-authoring, AC traceability, refinement, parallel-build, security-review, review-loop, commit-message-quality, AC-quality, refactor-safety, breaking-changes, conversation-language (always-on), anti-slop (always-on), plus a meta-skill that ties them together;
• stage runbooks (.cclaw/lib/runbooks/{plan,build,review,ship}.md) — strict checklists per stage with common pitfalls;
• reference patterns (.cclaw/lib/patterns/) — eight task-type playbooks (api-endpoint, auth-flow, schema-migration, ui-component, perf-fix, refactor, security-hardening, doc-rewrite) the orchestrator opens before authoring AC;
• research playbooks (.cclaw/lib/research/) — reading the codebase (files + tests + integration boundaries), time-boxing, using prior shipped slugs;
• recovery playbooks (.cclaw/lib/recovery/) — AC traceability break, review hard cap reached, parallel-build slice conflict, frontmatter corruption, schemaVersion mismatch;
• examples library (.cclaw/lib/examples/) — eight real-looking plan / build / review / ship / decision / learning / commit-helper artifacts;
• antipatterns (.cclaw/lib/antipatterns.md) — twelve known failure modes the reviewer cites as findings;
• decision protocol (.cclaw/lib/decision-protocol.md) — short-form digest of "is this even a decision?"; full D-N schema lives in lib/agents/architect.md, worked decisions in lib/examples/;
• resumable refinement via frontmatter on shipped slugs (refines: <old-slug>);
• durable artifacts your team and graph tools (Graphify, GitNexus, etc.) can index.

First 5 minutes

Requirements: Node.js 20+ and a git project.

cd /path/to/your/repo
npx cclaw-cli init                            # interactive picker; auto-detected harness pre-selected
npx cclaw-cli init --harness=claude,cursor,opencode,codex   # explicit, no picker

init resolves harnesses in this order:

1. --harness=<id>[,<id>] flag if passed.
2. Existing .cclaw/config.yaml (so subsequent init / sync / upgrade are deterministic).
3. Interactive picker when stdin/stdout are a TTY: a checkbox over the four harnesses with auto-detected ones pre-selected and tagged (detected). Up/Down or k/j to move, Space to toggle, a to select all, n to deselect all, Enter to confirm, Esc/Ctrl-C to cancel.
4. Non-TTY (CI, piped input, npm exec --yes): auto-detect from project root markers: .claude/, .cursor/, .opencode/, .codex/, .agents/skills/, CLAUDE.md, opencode.json, opencode.jsonc.
5. If nothing detected and no flag passed → exit with an actionable error. cclaw never silently picks a harness for you.

Then work entirely inside your harness:

/cc <task>          plan / build / review / ship — orchestrator routes everything
/cc-cancel          stop the active run cleanly (artifacts move to .cclaw/flows/cancelled/<slug>/)
/cc-idea            drop a half-formed idea into .cclaw/ideas.md (no flow started)

There is no cclaw plan, cclaw status, cclaw ship, or cclaw migrate CLI command. Flow control lives in /cc inside the harness.

Six specialists, all on demand

Specialists are proposed only when the task is large, abstract, risky, security-sensitive, or spans multiple components. Trivial and small/medium tasks run inline. Each prompt is 150-280 lines and includes an explicit output schema, two or more worked examples, edge cases, common pitfalls, and hard rules (see .cclaw/lib/agents/*.md after install). The orchestrator pulls additional context from runbooks, patterns, examples, and recovery playbooks as needed; see docs/skills.md for the auto-trigger layer that wraps every invocation.

.cclaw/state/ and .cclaw/worktrees/ are appended to .gitignore on init (transient per-session data). The rest of .cclaw/ is committable; graphify, team review, and the next agent all need it.

The split is deliberate. Active and archived flow artifacts go under flows/ so the orchestrator never confuses them with the read-only library under lib/. Runtime (state/, hooks/) stays at the top so harness hooks can find it without traversal. Active flows are grouped by slug — open flows/<slug>/ and every artifact for that flow is right there, instead of scattered across six per-stage subdirectories.

AC traceability gate (mandatory)

Ship is blocked unless every AC in the active plan is status: committed with a real commit SHA. The commit-helper.mjs hook is the only supported way to commit during /cc:

git add path/to/changed/file
node .cclaw/hooks/commit-helper.mjs --ac=AC-1 --message="implement approval pill"

The hook checks that AC-1 is declared in plan.md, refuses to run when flow-state.json schemaVersion is not 2, runs git commit, captures the new SHA, and writes it back into flow-state.json. If you commit by hand, AC traceability breaks and ship will refuse.

Compound learnings (automatic, gated)

After ship, cclaw automatically checks whether the run produced something worth remembering:

• a non-trivial decision was recorded by architect or planner, or
• review needed three or more iterations, or
• a security review ran or security_flag is true, or
• the user explicitly asked to capture (/cc <task> --capture-learnings).

If yes → flows/<slug>/learnings.md is written from the template, and one line is appended to knowledge.jsonl recording the slug, ship_commit, signals, and refines chain. If no → silently skipped, so the index stays signal-rich. Then everything moves to flows/shipped/<slug>/ with a manifest.md.

Parallel-build (cap: 5 slices, git worktree)

Inline is the default. Parallel-build is opt-in and only when planner declares it. Pre-conditions: ≥4 AC, ≥2 distinct touchSurface clusters, every AC parallelSafe: true, no AC depends on outputs of another AC in the same wave.

A slice = 1+ AC with a shared touchSurface. If planner produces more than 5 slices, planner must merge thinner slices into fatter ones — never generate "wave 2", "wave 3". The 5-slice cap is the v7-era constraint kept on purpose: orchestration cost grows non-linearly past 5 sub-agents, and 5 fits comfortably under every harness's sub-agent quota.

When the harness supports sub-agent dispatch, each parallel slice runs in its own worktree:

git worktree add .cclaw/worktrees/<slug>-slice-1 -b cclaw/<slug>/slice-1
git worktree add .cclaw/worktrees/<slug>-slice-2 -b cclaw/<slug>/slice-2
git worktree add .cclaw/worktrees/<slug>-slice-3 -b cclaw/<slug>/slice-3

Each slice-builder runs RED → GREEN → REFACTOR for every AC it owns sequentially inside its worktree. After the wave, reviewer in integration mode reads from each worktree's branch and the orchestrator merges them in. If the harness does not support sub-agent dispatch (or worktree creation fails), parallel-build degrades silently to inline-sequential — recorded but not an error.

For ≤4 AC the orchestrator picks inline even when AC look "parallelSafe". Dispatch overhead is not worth saving 1-2 AC of wall-clock.

When sub-agents help (and when they don't)

Use a sub-agent for:

• Parallel slice dispatch during parallel-build (cap: 5).
• Specialist context isolation for architect, security-reviewer, integration reviewer when the harness supports it. A fresh sub-agent reads a small focused filebag instead of the orchestrator's full history.

Don't use a sub-agent for:

• Trivial / small / medium slugs (≤4 AC). Run inline.
• Sequential work that doesn't actually parallelize.
• Routine work the orchestrator can finish in 1-2 turns.

Five Failure Modes + review Ralph loop

Reviews check the Five Failure Modes — hallucinated actions, scope creep, cascading errors, context loss, tool misuse — every iteration. The Five Failure Modes pass is wrapped by the review-loop auto-trigger skill so the agent cannot skip it.

Reviews are not single-shot. They are a Ralph loop with an explicit ledger:

1. Iteration 1 lists every finding as F-1, F-2, … in an append-only Concern Ledger at the top of flows/<slug>/review.md. Each row carries severity (block / warn), status (open / closed / superseded), and a file:line citation.
2. Iteration N+1 must reread every open row, mark it closed | open | superseded by F-K, and append new findings as F-(max+1). It cannot delete or rewrite earlier rows.
3. The loop ends when (a) every row is closed, (b) two consecutive iterations record zero new block findings AND every open row is warn, or (c) the 5-iteration hard cap fires with at least one open block row — at which point /cc stops and reports instead of looping forever.

A typical run converges in 1-3 iterations. The hard cap is a circuit breaker, not a target.

Conversation language

cclaw replies in the user's language for prose. It NEVER translates wire-protocol identifiers — slugs, AC-N, D-N, F-N, frontmatter keys, file paths, hook output, specialist names, or commit tags. This is enforced by the always-on conversation-language skill so a Russian-speaking user, for example, gets Russian explanations but still sees flow-state.json and AC-1 verbatim.

Hooks (default profile: minimal)

Three hooks ship by default and only commit-helper.mjs is mandatory:

• session-start.mjs — rehydrates flow state and prints active slug
• stop-handoff.mjs — short reminder when stopping mid-flow
• commit-helper.mjs — atomic commit per AC + traceability check

CLI commands

cclaw init                 # install assets in the current project
cclaw sync                 # reapply assets to match the current code
cclaw upgrade              # sync after upgrading the npm package
cclaw uninstall            # remove cclaw assets from the project
cclaw version              # print version
cclaw help                 # short help

Flow-control commands (plan, status, ship, migrate, build, review) are intentionally not part of the CLI. They live as /cc instructions inside the harness.
