Auto Mode

When -y or --yes: Skip clarification and confirmation prompts. Pass -y through to each step's skill invocation.

CCW

Usage

bash
$ccw "implement user authentication with JWT"
$ccw -y "refactor the payment module"
$ccw --continue
$ccw --dry-run "add rate limiting to API endpoints"
$ccw --chain feature "add dark mode toggle"

Flags:

• -y, --yes — Auto mode: skip all prompts; propagate -y to each skill
• --continue — Resume latest paused session from last incomplete wave
• --dry-run — Display planned chain without executing
• --chain <name> — Force a specific chain (skips intent classification)

Overview

Wave-based pipeline coordinator. The coordinator loop builds one wave CSV at a time, calls spawn_agents_on_csv, then performs coordinator-side artifact analysis before assembling the next wave. Barrier skills produce artifacts (plan.json, analysis results, etc.) that the coordinator reads to dynamically resolve args for subsequent steps.

Barrier Skills

Skills that produce artifacts requiring coordinator-side analysis before the next wave can be assembled. After a barrier skill completes, the coordinator reads its output and updates the execution context.

| Skill | Artifacts to Read | Context Updates | |-------|------------------|-----------------| | analyze-with-file | .workflow/.analysis/ANL-*/conclusions.json | analysis_dir, gaps, phase | | brainstorm-with-file | .workflow/.brainstorm/*/ | brainstorm_dir, features | | workflow-plan | .workflow/active/WFS-*/workflow-session.json | plan_dir, task_count | | workflow-lite-planex | .workflow/.lite-plan/*/plan.json | plan_dir, task_count | | spec-generator | .workflow/.spec/*/ | spec_session_id | | roadmap-with-file | .workflow/.roadmap/*/roadmap.md | roadmap_dir | | workflow-tdd-plan | .workflow/.tdd-plan/*/ | tdd_plan_dir | | issue-discover | .workflow/.issues/*/ | issue_dir, issue_count | | debug-with-file | .workflow/.debug/*/ | debug_dir, findings |

Non-barrier skills (can be grouped into multi-task waves): workflow-execute, workflow-test-fix-cycle, review-cycle, clean, investigate, security-audit, ship, parallel-dev-cycle, brainstorm, all team-* skills

Phase 1: Structured Intent Extraction

Extract a structured intent tuple using LLM semantic understanding, then route deterministically via an action × object matrix.

Extract structured intent from user input:

json
{
  "action":    "<from action enum>",
  "object":    "<from object enum>",
  "scope":     "<module/file/area or null>",
  "style":     "<from style enum>",
  "urgency":   "<low | normal | high>"
}

Action enum:

| action | Semantic meaning | |--------|-----------------| | create | Build something new — feature, project, component, spec | | fix | Repair something broken — fix bug, resolve error, patch | | analyze | Understand deeply — analyze, investigate, discuss, explore concept | | plan | Design approach — plan, break down, roadmap, decompose | | execute | Implement planned work — execute, implement, develop | | explore | Open-ended discovery — brainstorm, ideate, creative thinking | | debug | Diagnose failures — debug, diagnose, troubleshoot | | test | Run or create tests — test, generate test, TDD | | review | Evaluate code quality — review, code review | | refactor | Restructure code — refactor, clean up, tech debt | | convert | Bridge between workflows — convert brainstorm to issue |

Object enum:

| object | Meaning | |--------|---------| | feature | New functionality or enhancement | | bug | Defect, error, broken behavior | | issue | Issue-tracker item for batch/structured management | | code | Source code in general | | test | Tests, test suite, test coverage | | spec | Specification, PRD, product requirements | | doc | Documentation | | ui | User interface, design, component | | performance | Performance characteristics | | security | Security concerns | | architecture | System architecture, design decisions | | project | Entire project (greenfield) | | team | Team-based execution |

Style enum:

| style | Meaning | |-------|---------| | quick | Fast, lightweight, minimal ceremony | | documented | With file artifacts, discussion docs | | collaborative | Multi-agent, multi-perspective | | structured | Formal planning, spec-driven, phased | | iterative | Cycle-based, self-iterating with reflection | | tdd | Test-driven development | | default | No specific style preference |

Chain Map

Routing via detectTaskType(intent) → chain name → skill list.

Task Type Detection (action × object × style matrix)

javascript
function detectTaskType(intent) {
  const { action, object, style, urgency } = intent;

  // Urgency override
  if (urgency === 'high' && (action === 'fix' || object === 'bug')) return 'bugfix-hotfix';

  // Style-first routing
  if (style === 'tdd') return 'tdd';
  if (style === 'collaborative' && action === 'plan') return 'collaborative-plan';
  if (style === 'collaborative' && action === 'analyze') return 'analyze-wave';
  if (style === 'collaborative' && action !== 'plan') return 'multi-cli';
  if (style === 'iterative' && object === 'test') return 'integration-test';
  if (style === 'iterative' && action === 'refactor') return 'refactor';

  // Action × Object matrix
  const matrix = {
    'create': { 'project': 'greenfield', 'feature': 'feature', 'spec': 'spec-driven', 'test': 'test-gen', 'doc': 'documentation', 'ui': 'ui-design', 'issue': 'issue-batch', '_default': 'feature' },
    'fix':    { 'bug': 'bugfix', 'test': 'test-fix', 'issue': 'issue-batch', 'code': 'bugfix', 'security': 'bugfix', '_default': 'bugfix' },
    'analyze':{ 'architecture': 'analyze-file', 'code': 'analyze-file', 'bug': 'debug-file', 'security': 'security', '_default': 'analyze-file' },
    'explore':{ 'feature': 'brainstorm', 'architecture': 'brainstorm', 'issue': 'issue-batch', '_default': 'exploration' },
    'plan':   { 'feature': 'feature', 'project': 'greenfield', 'issue': 'issue-transition', '_default': 'feature' },
    'execute':{ 'issue': 'issue-transition', '_default': 'feature' },
    'debug':  { 'bug': style === 'documented' ? 'debug-file' : 'debug', '_default': style === 'documented' ? 'debug-file' : 'debug' },
    'test':   { 'test': 'test-fix', 'code': 'test-gen', 'feature': 'integration-test', '_default': 'test-gen' },
    'review': { '_default': 'review' },
    'refactor':{ '_default': 'refactor' },
    'convert':{ 'issue': 'brainstorm-to-issue', '_default': 'issue-transition' },
  };

  // Special compound detections
  if (action === 'plan' && style === 'structured' && /roadmap/.test(rawInput)) return 'roadmap';
  if (/csv.?wave|wave.?pipeline|并行波|波次执行/.test(rawInput)) return 'analyze-wave';
  if (object === 'team') return 'team-planex';
  if (/ship|release|publish/.test(rawInput)) return 'ship';

  const actionMap = matrix[action];
  if (!actionMap) return 'feature';
  return actionMap[object] || actionMap['_default'] || 'feature';
}

Implementation

Session Initialization

javascript
const dateStr = new Date().toISOString().substring(0, 10).replace(/-/g, '')
const timeStr = new Date().toISOString().substring(11, 19).replace(/:/g, '')
const sessionId = `CCW-${dateStr}-${timeStr}`
const sessionDir = `.workflow/.ccw-coordinate/${sessionId}`

Bash(`mkdir -p ${sessionDir}`)

Phase 1: Resolve Intent and Chain

--continue mode: Glob .workflow/.ccw-coordinate/CCW-*/state.json sorted by name desc; load the most recent; resume from first pending wave.

Fresh mode:

1. Read .workflow/state.json for project context (current_phase, workflow_name)
2. If --chain is given, use it directly
3. Otherwise, extract structured intent {action, object, scope, style, urgency} from user input using LLM semantic understanding
4. Route via detectTaskType(intent) matrix to get task_type
5. Assess complexity (low|medium|high) for complexity-adaptive routing
6. If no confident classification and not AUTO_YES: ask one clarifying question via AskUserQuestion
7. Resolve the chain's skill list from Chain Definitions
8. Write state.json:

javascript
Write(`${sessionDir}/state.json`, JSON.stringify({
  id: sessionId,
  intent,
  structured_intent: { action, object, scope, style, urgency },
  task_type,
  complexity,
  chain: resolvedChain,
  auto_yes: AUTO_YES,
  status: "in_progress",
  started_at: new Date().toISOString(),
  context: {
    phase: resolvedPhase,
    plan_dir: null,
    analysis_dir: null,
    brainstorm_dir: null,
    spec_session_id: null,
    roadmap_dir: null,
    tdd_plan_dir: null,
    issue_dir: null,
    debug_dir: null,
    gaps: null
  },
  waves: [],   // populated as waves execute
  steps: CHAIN_STEPS[resolvedChain].map((skill, i) => ({
    step_n: i + 1,
    skill: skill.cmd,
    args: skill.args ?? '',
    is_barrier: BARRIER_SKILLS.has(skill.cmd),
    status: "pending",
    wave_n: null
  }))
}, null, 2))

--dry-run: Display the chain plan and stop.

Chain:  <resolvedChain>
Type:   <task_type> | Complexity: <complexity>
Steps:
  1. $<cmd> <args>  [BARRIER]
  2. $<cmd> <args>
  3. $<cmd> <args>

User confirmation (skip if AUTO_YES): Display the plan above and prompt Proceed? (yes/no).

Phase 2: Wave Execution Loop

The coordinator iterates over pending steps, grouping them into waves and executing one wave at a time.

Wave Grouping Rules

1. A barrier skill is always alone in its wave (wave size = 1)
2. Consecutive non-barrier skills with no inter-dependencies are grouped into one wave (wave size = N)
3. After a barrier wave completes → coordinator analyzes artifacts → updates context → re-assembles subsequent step args

Per-Wave Execution

javascript
let waveNum = 0;

while (state.steps.some(s => s.status === 'pending')) {
  waveNum++;

  // 1. Determine wave contents
  const waveSteps = buildNextWave(state.steps);

  // 2. Assemble skill_call for each step (with latest context)
  const waveCsv = waveSteps.map((step, i) => ({
    id: String(step.step_n),
    skill_call: buildSkillCall(step, state.context),
    topic: `Chain "${state.chain}" step ${step.step_n}/${state.steps.length}`
  }));

  // 3. Write wave CSV
  const csvContent = 'id,skill_call,topic\n' + waveCsv.map(r =>
    `"${r.id}","${r.skill_call.replace(/"/g, '""')}","${r.topic}"`
  ).join('\n');
  Write(`${sessionDir}/wave-${waveNum}.csv`, csvContent);

  // 4. Execute wave
  spawn_agents_on_csv({
    csv_path: `${sessionDir}/wave-${waveNum}.csv`,
    id_column: "id",
    instruction: WAVE_INSTRUCTION,
    max_workers: waveSteps.length > 1 ? waveSteps.length : 1,
    max_runtime_seconds: 1800,
    output_csv_path: `${sessionDir}/wave-${waveNum}-results.csv`,
    output_schema: RESULT_SCHEMA
  });

  // 5. Read results, update step status
  const results = readCSV(`${sessionDir}/wave-${waveNum}-results.csv`);
  for (const row of results) {
    const step = state.steps.find(s => s.step_n === parseInt(row.id));
    step.status = row.status;
    step.findings = row.summary;
    step.artifacts = row.artifacts;
    step.wave_n = waveNum;
  }

  // 6. Barrier analysis (if wave contained a barrier skill)
  if (waveSteps.length === 1 && BARRIER_SKILLS.has(waveSteps[0].skill)) {
    analyzeBarrierArtifacts(waveSteps[0], results[0], state.context);
  }

  // 7. Persist state
  state.waves.push({ wave_n: waveNum, steps: waveSteps.map(s => s.step_n), results });
  Write(`${sessionDir}/state.json`, JSON.stringify(state, null, 2));

  // 8. Abort on failure
  if (results.some(r => r.status === 'failed')) {
    state.status = 'aborted';
    state.steps.filter(s => s.status === 'pending').forEach(s => s.status = 'skipped');
    Write(`${sessionDir}/state.json`, JSON.stringify(state, null, 2));
    break;
  }
}

Instruction Template

你是 CSV job 子 agent。

先原样执行这一段技能调用：
{skill_call}

然后基于结果完成这一行任务说明：
{topic}

限制：
- 不要修改 .workflow/.ccw-coordinate/ 下的 state 文件
- skill 内部有自己的 session 管理，按 skill SKILL.md 执行即可

最后必须调用 `report_agent_job_result`，返回 JSON：
{"status":"completed|failed","skill_call":"{skill_call}","summary":"一句话结果","artifacts":"产物路径或空字符串","error":"失败原因或空字符串"}

Result Schema

javascript
const RESULT_SCHEMA = {
  type: "object",
  properties: {
    status: { type: "string", enum: ["completed", "failed"] },
    skill_call: { type: "string" },
    summary: { type: "string" },
    artifacts: { type: "string" },
    error: { type: "string" }
  },
  required: ["status", "skill_call", "summary", "artifacts", "error"]
};

Barrier Analysis Logic

After a barrier skill completes, the coordinator reads its artifacts and updates state.context:

javascript
const BARRIER_SKILLS = new Set([
  'analyze-with-file', 'brainstorm-with-file', 'workflow-plan',
  'workflow-lite-planex', 'spec-generator', 'roadmap-with-file',
  'workflow-tdd-plan', 'issue-discover', 'debug-with-file'
]);

function analyzeBarrierArtifacts(step, result, ctx) {
  const artifactPath = result.artifacts;

  switch (step.skill) {
    case 'analyze-with-file':
      // Read analysis conclusions → extract gaps, phase info
      const analysisFiles = Glob('.workflow/.analysis/ANL-*/conclusions.json');
      const latest = analysisFiles.sort().pop();
      if (latest) {
        const conclusions = JSON.parse(Read(latest));
        ctx.analysis_dir = latest.replace('/conclusions.json', '');
        ctx.gaps = conclusions.gaps ?? null;
        if (!ctx.phase) ctx.phase = conclusions.phase ?? null;
      }
      break;

    case 'brainstorm-with-file':
      ctx.brainstorm_dir = artifactPath;
      break;

    case 'workflow-plan':
      // Read workflow session → know task structure for execute
      const wfSessions = Glob('.workflow/active/WFS-*/workflow-session.json');
      const latestWf = wfSessions.sort().pop();
      if (latestWf) {
        const session = JSON.parse(Read(latestWf));
        ctx.plan_dir = latestWf.replace('/workflow-session.json', '');
        ctx.task_count = session.tasks?.length ?? 0;
      }
      break;

    case 'workflow-lite-planex':
      const litePlans = Glob('.workflow/.lite-plan/*/plan.json');
      const latestPlan = litePlans.sort().pop();
      if (latestPlan) {
        ctx.plan_dir = latestPlan.replace('/plan.json', '');
        ctx.task_count = JSON.parse(Read(latestPlan)).tasks?.length ?? 0;
      }
      break;

    case 'spec-generator':
      ctx.spec_session_id = artifactPath;
      break;

    case 'roadmap-with-file':
      ctx.roadmap_dir = artifactPath;
      break;

    case 'workflow-tdd-plan':
      ctx.tdd_plan_dir = artifactPath;
      break;

    case 'issue-discover':
      ctx.issue_dir = artifactPath;
      break;

    case 'debug-with-file':
      ctx.debug_dir = artifactPath;
      ctx.findings = result.summary;
      break;
  }
}

Skill Call Assembly

The coordinator builds each skill_call with resolved context — sub-agents just execute verbatim:

javascript
const AUTO_FLAG_MAP = {
  'brainstorm-with-file': '-y',
  'analyze-with-file': '-y',
  'debug-with-file': '-y',
  'workflow-plan': '-y',
  'workflow-lite-planex': '-y',
  'workflow-execute': '-y',
  'workflow-test-fix-cycle': '-y',
  'workflow-tdd-plan': '-y',
  'spec-generator': '-y',
  'roadmap-with-file': '-y',
  'issue-discover': '-y',
  'parallel-dev-cycle': '-y',
  'review-cycle': '-y',
  'clean': '-y',
  'brainstorm': '-y',
  'csv-wave-pipeline': '-y',
};

function buildSkillCall(step, ctx) {
  let args = (step.args ?? '')
    .replace(/{intent}/g, state.intent ?? '')
    .replace(/{phase}/g, ctx.phase ?? '')
    .replace(/{plan_dir}/g, ctx.plan_dir ?? '')
    .replace(/{analysis_dir}/g, ctx.analysis_dir ?? '')
    .replace(/{brainstorm_dir}/g, ctx.brainstorm_dir ?? '')
    .replace(/{spec_session_id}/g, ctx.spec_session_id ?? '')
    .replace(/{roadmap_dir}/g, ctx.roadmap_dir ?? '')
    .replace(/{tdd_plan_dir}/g, ctx.tdd_plan_dir ?? '')
    .replace(/{issue_dir}/g, ctx.issue_dir ?? '')
    .replace(/{debug_dir}/g, ctx.debug_dir ?? '');

  // Inject intent as first arg if no args present
  if (!args.trim()) args = `"${state.intent}"`;

  if (state.auto_yes) {
    const flag = AUTO_FLAG_MAP[step.skill];
    if (flag && !args.includes(flag)) args = args ? `${args} ${flag}` : flag;
  }

  return `$${step.skill} ${args}`.trim();
}

function buildNextWave(steps) {
  const pending = steps.filter(s => s.status === 'pending');
  if (!pending.length) return [];

  const first = pending[0];
  // Barrier skill → solo wave
  if (BARRIER_SKILLS.has(first.skill)) return [first];

  // Group consecutive non-barriers
  const wave = [first];
  for (let i = 1; i < pending.length; i++) {
    if (BARRIER_SKILLS.has(pending[i].skill)) break;
    wave.push(pending[i]);
  }
  return wave;
}

Phase 3: Completion Report

javascript
state.status = state.steps.every(s => s.status === 'completed') ? 'completed' : state.status;
state.completed_at = new Date().toISOString();
Write(`${sessionDir}/state.json`, JSON.stringify(state, null, 2));

Generate context.md:

Error Handling

| Code | Severity | Condition | Recovery | |------|----------|-----------|----------| | E001 | error | Intent unclassifiable after clarification | Default to feature chain (rapid) | | E002 | error | --chain value not in chain map | List valid chains, abort | | E003 | error | Wave timeout (max_runtime_seconds) | Mark step failed, abort chain | | E004 | error | Barrier artifact not found | Retry wave once, then abort | | E005 | error | --continue: no session found | List sessions, prompt | | W001 | warning | Barrier artifact partial | Continue with available context |

Core Rules

1. Start Immediately: Init session dir and write state.json before any wave
2. Wave-by-wave: Never start wave N+1 before wave N results are read and analyzed
3. Barrier = solo wave: A barrier skill always executes alone; coordinator analyzes its artifacts before proceeding
4. Non-barriers can parallel: Consecutive non-barrier skills in the same wave execute with max_workers = N
5. Coordinator owns context: Sub-agents never read prior results — coordinator assembles the full skill_call with resolved args
6. Simple instruction: Sub-agent instruction is minimal — just "execute {skill_call}, report result"
7. Abort on failure: Failed step → mark remaining as skipped → report
8. State.json tracks waves: Each wave is recorded with step IDs and results for resume
9. Dry-run is read-only: Display chain with BARRIER] markers, no execution
10. Resume from wave: --continue finds last completed wave and resumes from next pending step
11. Semantic Routing: Use LLM structured extraction (action × object × style) not regex for intent classification
