cclaw

A multi-stage planning + review harness for coding agents.

cclaw drops a /cc slash command into Claude Code, Cursor, OpenCode, or Codex. It routes the task, picks the right amount of ceremony, and runs the work through a fixed pipeline: route → plan → build → qa → review → critic → ship. Each stage emits a slim summary back to the harness and writes a tracked artifact under .cclaw/flows/<slug>/. Sub-agents are isolated; the orchestrator keeps the slug's history.

cclaw installs /cc and /cc-cancel into each harness. Inside /cc, three entry modes cover task work, research, and continuation flows — see When to use which command and Modes.

Why cclaw

• Pipeline, not autopilot, but no friction either. v8.61 — the flow runs end-to-end without approval pickers at plan / review / critic gates (always-auto). Hard failures stop and report with a clear status block; the user resumes with /cc (continue) or /cc-cancel (discard). See Failure handling below.
• Two-model review. A read-only reviewer walks ten axes; an adversarial critic falsifies what the reviewer cleared. They share no context and write to separate artifacts (review.md, critic.md).
• Right-sized ceremony. Trivial edits run inline (one commit, no plan). Small/medium tasks get a soft-mode plan and a single TDD cycle. Large-risky tasks get a full per-criterion build with a pre-implementation plan-critic gate.
• Lightweight router as a sub-agent. v8.61 — triage moved from the main orchestrator context to a dedicated triage specialist (one of nine sub-agents). The router is still zero-question by default (no structured ask, no clarifying prompt). Explicit override flags (/cc --inline <task> / /cc --soft <task> / /cc --strict <task>) short-circuit the heuristic when you want to pin a ceremony level. Classification work (surface detection, assumption capture, prior-learnings, interpretation forks) moved into the specialist that already has the codebase context — design Phase 0-2 on strict, ac-author Phase 0-1 on soft.
• Research mode. /cc research <topic> is a separate entry point for pre-task uncertainty: brainstorming, scope exploration, architecture comparison. Runs the design specialist standalone (Phase 0 Bootstrap → Phase 6 Compose), emits a research.md synthesis artifact, and stops. Optional handoff into a follow-up /cc <clarified task> flow that consumes the research as priorResearch context.
• Continuation flow. /cc extend <slug> <task> loads a previously-shipped slug as parent context for iterative work that explicitly builds on a previously-shipped slug. Loads the parent's plan.md / build.md / learnings.md (and review.md / critic.md / qa.md when present) into flowState.parentContext. Triage inherits ceremonyMode / surfaces from the parent under v8.61 always-auto (legacy runMode parents fold to auto; explicit --strict / --soft / --inline flags still override). The new flow's plan.md carries a ## Extends section + parent_slug: frontmatter that points back at the parent.
• Same runtime, four harnesses. Claude Code, Cursor, OpenCode, and Codex all read the same .cclaw/ install. Each harness gets the same /cc body plus harness-namespaced ambient rules.
• Compound learnings. Non-trivial slugs emit a learnings.md. Future runs read prior shipped lessons through knowledge.jsonl before authoring a plan; outcome signals (good / unknown / manual-fix / follow-up-bug / reverted) down-weight priors that didn't hold up.

When to use which command

Quickstart

cd /path/to/your/repo
npx cclaw-cli@latest

# Inside your harness:
/cc add caching to the search endpoint

# v8.61 — the flow runs always-auto: plan → build → review → critic → ship
# without approval pickers. cclaw stops only when a hard failure fires
# (build broken, reviewer can't converge in 3 fixes, critic block-ship,
# catastrophic git/dispatch failure). Resume with /cc; discard with
# /cc-cancel. See "If something goes wrong" below.
ls .cclaw/flows/20260515-search-caching/
# plan.md  build.md  review.md  critic.md  ship.md

For CI / scripted installs, use the non-interactive escape hatch:

npx cclaw-cli@latest --non-interactive install --harness=cursor

There is no cclaw plan, cclaw build, or cclaw status. Flow control lives inside /cc.

/cc invocation matrix (v8.61)

If something goes wrong

cclaw v8.61 runs always-auto, so the recovery loop is uniform:

1. cclaw stops at the first hard failure and writes a status block to chat naming the stage, the reason, and the recovery options.
2. You read the status block (the artifact under .cclaw/flows/<slug>/ carries the full detail).
3. You decide: /cc to continue (after editing the diff / plan / review.md as needed), or /cc-cancel to discard the slug entirely.

There is no in-chat picker, no [y/n] ask, no "approve this?" gate. The status block is plain prose; recovery is always one of two typed commands.

Modes

v8.59 ships three top-level entry points. All invocations use the same /cc slash-command surface; the orchestrator picks which mode to run based on the first token after /cc.

/cc <task> — task mode (the historical default)

Runs the full route → plan → build → ship pipeline. v8.61 — the router moved to a triage sub-agent dispatch (Hop 2 of the orchestrator). It still picks complexity × ceremonyMode × path from heuristics and announces the choice in one line, then dispatches the first specialist. No clarifying questions; no structured ask. If you want to pin a ceremony level explicitly, pass one of:

/cc --inline <task>    # forces inline edit (one commit, no plan)
/cc --soft <task>      # forces soft-mode plan → build → review → ship
/cc --strict <task>    # forces strict + design Phase 0-7 + per-criterion commits + plan-critic gate

The flags are mutually exclusive. v8.61 retired the user-facing --mode=auto / --mode=step runMode toggle — both are accepted on the parser for back-compat but collapse to auto (the only behavioural mode in v8.61). When the project has no .git/, the router auto-downgrades strict → soft even with --strict (per-criterion commits need a SHA chain to be useful).

What used to live at the router — surface detection, assumption capture, prior-learnings lookup, interpretation forks — now lives inside the specialist that has the codebase context to do it well: design Phase 0-2 (strict), ac-author Phase 0-1 (soft), nothing (inline). Pre-v8.58 state files continue to validate verbatim; readers default to mode: "task" when the field is absent.

/cc research <topic> — research mode (v8.58 new entry point)

Runs the design specialist in standalone activation mode — same Phase 0-6 as the in-flow brainstormer (Bootstrap → Clarify → Frame → Approaches → Decisions → Pre-mortem → Compose), but stops at Compose. Output: .cclaw/flows/<slug>/research.md. No build / review / critic / ship. The Phase 7 picker is a two-option accept research / revise (instead of the intra-flow three-option approve / request-changes / reject).

/cc research storage strategy for shared agent memory
/cc --research auth library trade-offs                 # equivalent

After accepting the research, the orchestrator surfaces a plain-prose handoff:

Ready to plan? Run /cc <clarified task description> and I'll carry the research forward as context.

The next /cc <task> invocation on the same project reads flow-state.json > priorResearch and consumes the most-recent shipped research as input to its plan stage (design Phase 0 / ac-author Phase 0 include the research artifact in their reads). The handoff is optional — if you accept the research and never run a follow-up /cc, nothing else fires.

Research mode skips the router entirely. There is no triage gate; no complexity / ceremonyMode heuristic runs. The orchestrator stamps a sentinel triage block (mode: "research", ceremonyMode: "strict", path: ["plan"]) so downstream readers that assume triage is present continue to work.

/cc extend <slug> <task> — continuation mode (v8.59 new entry point)

Initialises a new flow that explicitly extends a previously-shipped slug. The orchestrator loads the parent's plan.md, build.md, learnings.md, and (when present) review.md / critic.md / qa.md as flowState.parentContext and surfaces them to design / ac-author / reviewer / critic as load-bearing context. Things already settled by the parent are NOT re-decided in the new flow.

/cc extend 20260514-auth-flow add SAML login                   # canonical
/cc extend 20260514-auth-flow --strict refactor session store  # ceremony override wins over inheritance
/cc extend 20260514-cli-help fix typo in --help                # inheritance + always-auto

The orchestrator runs the same pipeline as a standard /cc <task> (plan → build → qa? → review → critic → ship); the only difference is at init:

• Parent validation. loadParentContext(projectRoot, <slug>) (src/parent-context.ts) confirms the slug is shipped + has a non-empty plan.md. Four failure modes are explicit: in-flight (slug still active), cancelled (under flows/cancelled/), corrupted (shipped but plan.md missing), missing (slug not found anywhere). Each surfaces a one-line error and ends the turn.
• State stamp. The new flow's flow-state.json > parentContext carries the parent's slug + status + shippedAt + structured artifact paths. Plan.md frontmatter carries parent_slug: <parent> (v8.59-native) plus refines: <parent> (back-compat with the knowledge-store chain, qa-runner skip rule, plan-critic skip gate, design Phase 6 brownfield path).
• Triage inheritance. The new flow's ceremonyMode / surfaces default to the parent's values. runMode is v8.61 always-auto regardless of the parent (legacy step parents fold to auto). Explicit --strict / --soft / --inline flags override the ceremonyMode inheritance. A security-keyword escalation heuristic (security / auth / migration / schema / payment / gdpr / pci) auto-escalates a soft/inline parent → strict for the new flow.
• Specialist consumption. design Phase 0 reads parent's ## Spec / ## Decisions / ## Selected Direction and surfaces "Building on prior decisions: …". ac-author Phase 1.7 authors a mandatory ## Extends section at the top of plan.md with parent slug + 1-line decision summary + clickable links to parent artifacts. reviewer runs a lightweight parent-contradictions cross-check (silent reversals of a parent D-N are required findings). critic §3 adds a skeptic question on parent decision contradictions.
• Knowledge-store integration. When parentContext is set, findNearKnowledge prepends the parent's knowledge.jsonl entry to the top of the prior-learnings result (load-bearing context overrides Jaccard ranking).

v8.59 loads the immediate parent only — multi-level chains (grandparent → parent → child) are not auto-walked. Specialists may use findRefiningChain on demand when transitive context is needed; multi-level auto-loading at orchestrator level is v8.60+ scope.

Worked example

You type:

/cc add caching to the search endpoint

The orchestrator runs through these stages in order, chaining automatically (v8.61 always-auto). The slim-summary blocks the orchestrator emits sit under ## Triage, ## Plan, ## Build, ## QA, ## Review, ## Critic, ## Ship section headers in chat. Artifacts land on disk.

• Triage (v8.61 sub-agent). The orchestrator dispatches the triage specialist with the raw /cc argument. Triage returns a 5-field decision in one slim summary — complexity: small-medium · ceremony mode: soft · path: plan → build → review → critic → ship · runMode: auto · mode: task. Slug: 20260515-search-caching. Zero clarifying asks. The decision is persisted to flow-state.json > triage and is immutable for the slug. (v8.58 — surface detection / assumption capture / prior-learnings lookup moved into ac-author Phase 0-1 on the soft path; v8.61 — the triage routing prose moved out of the orchestrator body into triage.md.)
• Plan. ac-author writes plan.md — Spec section (Objective / Success / Out of scope / Boundaries), Frame, Acceptance Criteria, Edge cases, Topology, Feasibility stamp, Traceability block. 3 AC, 2 prior lessons surfaced from knowledge.jsonl. Confidence: high.
• Build. slice-builder runs one TDD cycle per criterion: RED → GREEN → REFACTOR. Each commit carries an AC-N prefix the reviewer reads via git log --grep. Tests: 14 passing (was 11). Coverage delta: +2.3%. Build failures trigger an auto-fix loop (up to 3 iterations); failure after 3 stops and reports.
• Review. Ten-axis reviewer opens 2 findings on the first iteration: cache-key collision on case-sensitive queries (correctness, required) and missing TTL refresh on stale entries (architecture, consider). Reviewer critical / required-no-fix triggers an auto-dispatch fix-only loop (up to 3 iterations); failure after 3 stops and reports.
• Critic. Adversarial falsificationist pass — predictions, gap analysis, Criterion check across AC + Edge cases + NFR rows, goal-backward verification, realist check. Verdict: pass. block-ship stops immediately (no auto-iteration — re-running on unchanged code returns the same verdict).
• Ship. All 3 AC committed. ship.md carries the release-notes draft and the AC↔commit map. Chains automatically to push under v8.61 always-auto.

After ship, the orchestrator moves the artifacts to .cclaw/flows/shipped/<slug>/ and (when the slug earned capture) appends one row to .cclaw/state/knowledge.jsonl.

Failure handling (v8.61 always-auto)

cclaw stops at hard failures per a fixed matrix. The recovery loop is always the same: read the status block, decide, type /cc (continue) or /cc-cancel (discard).

The status block names the stage, the reason, and the recovery options. Example:

Stopped at review (iteration 3). Reason: reviewer returned 2 critical findings after fix-only loop hit the 3-iteration cap.
To proceed: /cc to continue (continues from the saved state), or /cc-cancel to discard the slug.

What you get

Harnesses supported

Run npx cclaw-cli@latest and the TUI auto-detects whatever you have. For CI / scripted installs, pass --non-interactive install --harness=<id>[,<id>] (comma-separated; supported ids: claude, cursor, opencode, codex).

Configuration

.cclaw/config.yaml is optional. Defaults are good. Common knobs:

harnesses: [claude, cursor]
reviewerTwoPass: false              # opt-in: spec-review + code-quality-review split
compoundRefreshEvery: 5             # how often to dedup knowledge.jsonl
compoundRefreshFloor: 10            # minimum entries before refresh kicks in
captureLearningsBypass: false       # true = silent skip on non-trivial slugs
legacy-artifacts: false             # true brings back v8.11-era extra artifacts
design:
  ambiguity_threshold: 0.2          # v8.53 — design Phase 7 soft warning threshold

Architecture deep dive

The runtime is under 1 KLOC. The prompt content is where the work lives. If you want to understand how /cc actually works, read the source — the on-disk reference lives under src/content/:

• src/content/start-command.ts — orchestrator body (detect, dispatch, always-auto chain, critic step, ship, compound, finalize). v8.61 dropped the inline triage prose; the orchestrator dispatches the triage sub-agent at Hop 2.
• src/content/specialist-prompts/ — 9 specialist contracts (v8.61 added triage.ts).
• src/content/skills/ — 21 auto-trigger skill bodies.
• src/content/runbooks-on-demand.ts — 13 on-demand runbooks the orchestrator opens by trigger (v8.61 added always-auto-failure-handling).
• src/content/artifact-templates.ts — plan / build / qa / review / critic / plan-critic / ship / learnings templates.
• src/content/anti-rationalizations.ts — cross-cutting rebuttal catalog (v8.49+).
• CHANGELOG.md — release history.

CLI surface

Two invocations cover every use case. There is no cclaw plan / cclaw status / cclaw build / cclaw ship — flow control lives inside /cc. The bare subcommand surface (init, sync, upgrade) was retired in v8.29 + v8.37.

# Interactive (humans): opens a TUI menu — Install / Uninstall / Quit
npx cclaw-cli@latest

# Non-interactive (CI / scripts): explicit command, no TUI
npx cclaw-cli@latest --non-interactive install [--harness=<id>[,<id>]]
npx cclaw-cli@latest --non-interactive uninstall
npx cclaw-cli@latest --non-interactive knowledge [--tag=<tag>] [--surface=<sub>] [--type=<kind>] [--all] [--json]
npx cclaw-cli@latest --version
npx cclaw-cli@latest --help

install is idempotent and runs orphan cleanup, so it handles first-time setup, re-sync after a package upgrade, and stale-file cleanup in one command. The TUI menu and the --non-interactive install path share the same installer code — they are byte-for-byte identical in write behaviour.

Contributing

cclaw is dogfooded — every release is shipped via /cc against itself. To contribute:

1. Fork and clone.
2. npm install && npm run build && npm test (the test suite is the spec; PRs without test updates are rare).
3. Run /cc <your change> inside a cclaw-installed harness, or write tests + code directly.
4. Open a PR. CI runs lint, typecheck, unit tests, integration tests, and a smoke runtime test.

The runtime stays under 1 KLOC; new behaviour usually means new prompt content under src/content/, not new code under src/.
