Overview

Wave-based batch execution using spawn_agents_on_csv with cross-wave context propagation. Tasks are grouped into dependency waves; each wave executes concurrently, and its results feed into the next wave.

Core workflow: Decompose → Compute Waves → Execute Wave-by-Wave → Aggregate

Phase 1: Requirement → CSV
   ├─ Parse requirement into subtasks (3-10 tasks)
   ├─ Identify dependencies (deps column)
   ├─ Compute dependency waves (topological sort → depth grouping)
   ├─ Generate tasks.csv with wave column
   └─ User validates task breakdown (skip if -y)

Phase 2: Wave Execution Engine
   ├─ For each wave (1..N):
   │   ├─ Build wave CSV (filter rows for this wave)
   │   ├─ Inject previous wave findings into prev_context column
   │   ├─ spawn_agents_on_csv(wave CSV)
   │   ├─ Collect results, merge into master tasks.csv
   │   └─ Check: any failed? → skip dependents or retry
   └─ discoveries.ndjson shared across all waves (append-only)

Phase 3: Results Aggregation
   ├─ Export final results.csv
   ├─ Generate context.md with all findings
   ├─ Display summary: completed/failed/skipped per wave
   └─ Offer: view results | retry failed | done

Context Propagation

Two context channels flow across waves:

1. CSV findings (structured): context_from column → prev_context injection — task-specific directed context
2. NDJSON discoveries (broadcast): discoveries.ndjson — general exploration findings available to all

Wave 1 agents:
  ├─ Execute tasks (no prev_context)
  ├─ Write findings to report_agent_job_result
  └─ Append discoveries to discoveries.ndjson
        ↓ merge results into master CSV
Wave 2 agents:
  ├─ Read discoveries.ndjson (exploration sharing)
  ├─ Read prev_context column (wave 1 findings from context_from)
  ├─ Execute tasks with full upstream context
  ├─ Write findings to report_agent_job_result
  └─ Append new discoveries to discoveries.ndjson
        ↓ merge results into master CSV
Wave 3+ agents: same pattern, accumulated context from all prior waves

Per-Wave CSV (Temporary)

Each wave generates a temporary wave-{N}.csv with an extra prev_context column built from context_from by looking up completed tasks' findings in the master CSV:

id,title,description,test,acceptance_criteria,scope,hints,execution_directives,deps,context_from,wave,prev_context
"2","Implement OAuth","Add OAuth integration","Unit test: mock OAuth callback returns valid token","OAuth login redirects to provider; callback returns JWT","src/auth/oauth/**","Use passport.js strategy pattern || src/auth/index.ts;docs/oauth-flow.md","Run npm test -- --grep oauth","1","1","2","[Task 1] Created auth/ with index.ts and types.ts"
"3","Add JWT tokens","Implement JWT","Unit test: sign/verify round-trip; Edge test: expired token returns 401","generateToken() returns valid JWT; verifyToken() rejects expired/tampered tokens","src/auth/jwt/**","Use jsonwebtoken library; Set default expiry 1h || src/config/auth.ts","Ensure tsc --noEmit passes","1","1","2","[Task 1] Created auth/ with index.ts and types.ts"

Shared Discovery Board Protocol

All agents across all waves share discoveries.ndjson. This eliminates redundant codebase exploration.

Lifecycle: Created by the first agent to write a discovery. Carries over across waves — never cleared. Agents append via echo '...' >> discoveries.ndjson.

Format: NDJSON, each line is a self-contained JSON:

{"ts":"2026-02-28T10:00:00+08:00","worker":"1","type":"code_pattern","data":{"name":"repository-pattern","file":"src/repos/Base.ts","description":"Abstract CRUD repository"}}
{"ts":"2026-02-28T10:01:00+08:00","worker":"2","type":"integration_point","data":{"file":"src/auth/index.ts","description":"Auth module entry","exports":["authenticate","authorize"]}}

Discovery Types:

Protocol Rules:

1. Read board before own exploration → skip covered areas
2. Write discoveries immediately via echo >> → don't batch
3. Deduplicate — check existing entries; skip if same type + dedup key exists
4. Append-only — never modify or delete existing lines

Implementation

Session Initialization

const getUtc8ISOString = () => new Date(Date.now() + 8 * 60 * 60 * 1000).toISOString()

// Parse flags
const AUTO_YES = $ARGUMENTS.includes('--yes') || $ARGUMENTS.includes('-y')
const continueMode = $ARGUMENTS.includes('--continue')
const concurrencyMatch = $ARGUMENTS.match(/(?:--concurrency|-c)\s+(\d+)/)
const maxConcurrency = concurrencyMatch ? parseInt(concurrencyMatch[1]) : 4

// Clean requirement text (remove flags — word-boundary safe)
const requirement = $ARGUMENTS
  .replace(/--yes|(?:^|\s)-y(?=\s|$)|--continue|--concurrency\s+\d+|-c\s+\d+/g, '')
  .trim()

let sessionId, sessionFolder

const slug = requirement.toLowerCase()
  .replace(/[^a-z0-9\u4e00-\u9fa5]+/g, '-')
  .substring(0, 40)
const dateStr = getUtc8ISOString().substring(0, 10).replace(/-/g, '')
sessionId = `cwp-${slug}-${dateStr}`
sessionFolder = `.workflow/.csv-wave/${sessionId}`

// Continue mode: find existing session
if (continueMode) {
  const existing = Bash(`ls -t .workflow/.csv-wave/ 2>/dev/null | head -1`).trim()
  if (existing) {
    sessionId = existing
    sessionFolder = `.workflow/.csv-wave/${sessionId}`
    // Read existing tasks.csv, find incomplete waves, resume from there
    const existingCsv = Read(`${sessionFolder}/tasks.csv`)
    // → jump to Phase 2 with remaining waves
  }
}

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

CSV Utility Functions

// Escape a value for CSV (wrap in quotes, double internal quotes)
function csvEscape(value) {
  const str = String(value ?? '')
  return str.replace(/"/g, '""')
}

// Parse CSV string into array of objects (header row → keys)
function parseCsv(csvString) {
  const lines = csvString.trim().split('\n')
  if (lines.length < 2) return []
  const headers = parseCsvLine(lines[0]).map(h => h.replace(/^"|"$/g, ''))
  return lines.slice(1).map(line => {
    const cells = parseCsvLine(line).map(c => c.replace(/^"|"$/g, '').replace(/""/g, '"'))
    const obj = {}
    headers.forEach((h, i) => { obj[h] = cells[i] ?? '' })
    return obj
  })
}

// Parse a single CSV line respecting quoted fields with commas/newlines
function parseCsvLine(line) {
  const cells = []
  let current = ''
  let inQuotes = false
  for (let i = 0; i < line.length; i++) {
    const ch = line[i]
    if (inQuotes) {
      if (ch === '"' && line[i + 1] === '"') {
        current += '"'
        i++ // skip escaped quote
      } else if (ch === '"') {
        inQuotes = false
      } else {
        current += ch
      }
    } else {
      if (ch === '"') {
        inQuotes = true
      } else if (ch === ',') {
        cells.push(current)
        current = ''
      } else {
        current += ch
      }
    }
  }
  cells.push(current)
  return cells
}

Phase 1: Requirement → CSV

Objective: Decompose requirement into tasks, compute dependency waves, generate tasks.csv.

Steps:

1. Decompose Requirement ` // Use ccw cli to decompose requirement into subtasks Bash({command: ccw cli -p "PURPOSE: Decompose requirement into 3-10 atomic tasks for batch agent execution. Each task must include implementation description, test cases, and acceptance criteria. ``

TASK: • Parse requirement into independent subtasks • Identify dependencies between tasks (which must complete before others) • Identify context flow (which tasks need previous tasks' findings) • For each task, define concrete test cases (unit/integration/edge) • For each task, define measurable acceptance criteria (what defines 'done') • Each task must be executable by a single agent with file read/write access MODE: analysis CONTEXT: @**/* EXPECTED: JSON object with tasks array. Each task: {id: string, title: string, description: string, test: string, acceptance_criteria: string, scope: string, hints: string, execution_directives: string, deps: string[], context_from: string[]}.

• description: what to implement (specific enough for an agent to execute independently)
• test: what tests to write and how to verify (e.g. 'Unit test: X returns Y; Edge test: handles Z')
• acceptance_criteria: measurable conditions that define done (e.g. 'API returns 200; token expires after 1h')
• scope: target file/directory glob (e.g. 'src/auth/**') — tasks in same wave MUST have non-overlapping scopes
• hints: implementation tips + reference files, format ' || <ref_file1>;<ref_file2>' (e.g. 'Use strategy pattern || src/base/Strategy.ts;docs/design.md')
• execution_directives: commands to run for verification or tool constraints (e.g. 'Run npm test --bail; Ensure tsc passes')
• deps: task IDs that must complete first
• context_from: task IDs whose findings are needed CONSTRAINTS: 3-10 tasks | Each task is atomic | No circular deps | test and acceptance_criteria must be concrete and verifiable | Same-wave tasks must have non-overlapping scopes

REQUIREMENT: ${requirement}" --tool gemini --mode analysis --rule planning-breakdown-task-steps`, run_in_background: true}) // Wait for CLI completion via hook callback // Parse JSON from CLI output → decomposedTasks[]

2. **Compute Waves** (Kahn's BFS topological sort with depth tracking)

// Algorithm: // 1. Build in-degree map and adjacency list from deps // 2. Enqueue all tasks with in-degree 0 at wave 1 // 3. BFS: for each dequeued task at wave W, for each dependent D: // - Decrement D's in-degree // - D.wave = max(D.wave, W + 1) // - If D's in-degree reaches 0, enqueue D // 4. Any task without wave assignment → circular dependency error // // Wave properties: // Wave 1: no dependencies — fully independent // Wave N: all deps in waves 1..(N-1) — guaranteed completed before start // Within a wave: tasks are independent → safe for concurrent execution // // Example: // A(no deps)→W1, B(no deps)→W1, C(deps:A)→W2, D(deps:A,B)→W2, E(deps:C,D)→W3 // Wave 1: [A,B] concurrent → Wave 2: [C,D] concurrent → Wave 3: [E]

function computeWaves(tasks) { const taskMap = new Map(tasks.map(t => [t.id, t])) const inDegree = new Map(tasks.map(t => [t.id, 0])) const adjList = new Map(tasks.map(t => [t.id, []]))

for (const task of tasks) { for (const dep of task.deps) { if (taskMap.has(dep)) { adjList.get(dep).push(task.id) inDegree.set(task.id, inDegree.get(task.id) + 1) } } }

// BFS-based topological sort with depth tracking const queue = [] // [taskId, depth] const waveAssignment = new Map()

for (const [id, deg] of inDegree) { if (deg === 0) { queue.push([id, 1]) waveAssignment.set(id, 1) } }

let maxWave = 1 let idx = 0 while (idx < queue.length) { const [current, depth] = queue[idx++] for (const next of adjList.get(current)) { const newDeg = inDegree.get(next) - 1 inDegree.set(next, newDeg) const nextDepth = Math.max(waveAssignment.get(next) || 0, depth + 1) waveAssignment.set(next, nextDepth) if (newDeg === 0) { queue.push([next, nextDepth]) maxWave = Math.max(maxWave, nextDepth) } } }

// Detect cycles for (const task of tasks) { if (!waveAssignment.has(task.id)) { throw new Error(Circular dependency detected involving task ${task.id}) } }

return { waveAssignment, maxWave } }

const { waveAssignment, maxWave } = computeWaves(decomposedTasks)

1. **Generate tasks.csv** `` const header = 'id,title,description,test,acceptance_criteria,scope,hints,execution_directives,deps,context_from,wave,status,findings,files_modified,tests_passed,acceptance_met,error' const rows = decomposedTasks.map(task => {const wave = waveAssignment.get(task.id) return [task.id, csvEscape(task.title), csvEscape(task.description), csvEscape(task.test), csvEscape(task.acceptance_criteria), csvEscape(task.scope), csvEscape(task.hints), csvEscape(task.execution_directives), task.deps.join(';'), task.context_from.join(';'), wave, 'pending', // status '', // findings '', // files_modified '', // tests_passed '', // acceptance_met '' // error].map(cell => `"${String(cell).replace(/"/g, '""')}"`).join(',')}) Write(`${sessionFolder}/tasks.csv`, [header,...rows].join('\n')) ``
2. **User Validation** (skip if AUTO_YES) `` if (!AUTO_YES) {// Display task breakdown with wave assignment console.log(`\n## Task Breakdown (${decomposedTasks.length} tasks, ${maxWave} waves)\n`) for (let w = 1; w <= maxWave; w++) {const waveTasks = decomposedTasks.filter(t => waveAssignment.get(t.id) === w) console.log(`### Wave ${w} (${waveTasks.length} tasks, concurrent)`) waveTasks.forEach(t => console.log(` - [${t.id}] ${t.title}`))} const answer = functions.request_user_input({questions: [{header: "验证", id: "validation", question: "Approve task breakdown?", options: [{label: "Approve(Recommended)", description: "Proceed with wave execution"}, {label: "Modify", description: `Edit ${sessionFolder}/tasks.csv manually, then --continue`}, {label: "Cancel", description: "Abort"}]}]}) // BLOCKS if (answer.answers.validation.answers[0] === "Modify") {console.log(`Edit: ${sessionFolder}/tasks.csv\nResume: $csv-wave-pipeline --continue`) return} else if (answer.answers.validation.answers[0] === "Cancel") {return}} ``

**Success Criteria**: tasks.csv created with valid schema and wave assignments, no circular dependencies, user approved (or AUTO_YES).

---

### Phase 2: Wave Execution Engine

**Objective**: Execute tasks wave-by-wave via `spawn_agents_on_csv`. Each wave sees previous waves' results.

**Steps**:

1. **Wave Loop** `` const failedIds = new Set() const skippedIds = new Set() for (let wave = 1; wave <= maxWave; wave++) {console.log(`\n## Wave ${wave}/${maxWave}\n`) // 1. Read current master CSV const masterCsv = parseCsv(Read(`${sessionFolder}/tasks.csv`)) // 2. Filter tasks for this wave const waveTasks = masterCsv.filter(row => parseInt(row.wave) === wave) // 3. Skip tasks whose deps failed const executableTasks = [] for (const task of waveTasks) {const deps = task.deps.split(';').filter(Boolean) if (deps.some(d => failedIds.has(d) || skippedIds.has(d))) {skippedIds.add(task.id) updateMasterCsvRow(sessionFolder, task.id, {status: 'skipped', error: 'Dependency failed or skipped'}) console.log(` [${task.id}] ${task.title} → SKIPPED (dependency failed)`) continue} executableTasks.push(task)} if (executableTasks.length === 0) {console.log(` No executable tasks in wave ${wave}`) continue} // 4. Build prev_context for each task (from context_from → master CSV findings) for (const task of executableTasks) {const contextIds = task.context_from.split(';').filter(Boolean) const prevFindings = contextIds.map(id => {const prevRow = masterCsv.find(r => r.id === id) if (prevRow && prevRow.status === 'completed' && prevRow.findings) {return `[Task ${id}: ${prevRow.title}] ${prevRow.findings}`} return null}).filter(Boolean).join('\n') task.prev_context = prevFindings || 'No previous context available'} // 5. Write wave CSV const waveHeader = 'id,title,description,test,acceptance_criteria,scope,hints,execution_directives,deps,context_from,wave,prev_context' const waveRows = executableTasks.map(t => [t.id, t.title, t.description, t.test, t.acceptance_criteria, t.scope, t.hints, t.execution_directives, t.deps, t.context_from, t.wave, t.prev_context].map(cell => `"${String(cell).replace(/"/g, '""')}"`).join(',')) Write(`${sessionFolder}/wave-${wave}.csv`, [waveHeader,...waveRows].join('\n')) // 6. Execute wave console.log(` Executing ${executableTasks.length} tasks (concurrency: ${maxConcurrency})...`) const waveResult = spawn_agents_on_csv({csv_path: `${sessionFolder}/wave-${wave}.csv`, id_column: "id", instruction: buildInstructionTemplate(sessionFolder, wave), max_concurrency: maxConcurrency, max_runtime_seconds: 600, output_csv_path: `${sessionFolder}/wave-${wave}-results.csv`, output_schema: {type: "object", properties: {id: {type: "string"}, status: {type: "string", enum: ["completed", "failed"]}, findings: {type: "string"}, files_modified: {type: "array", items: {type: "string"}}, tests_passed: {type: "boolean"}, acceptance_met: {type: "string"}, error: {type: "string"}}, required: ["id", "status", "findings", "tests_passed"]}}) // ↑ Blocks until all agents in this wave complete // 7. Merge results into master CSV const waveResults = parseCsv(Read(`${sessionFolder}/wave-${wave}-results.csv`)) for (const result of waveResults) {updateMasterCsvRow(sessionFolder, result.id, {status: result.status, findings: result.findings || '', files_modified: (result.files_modified || []).join(';'), tests_passed: String(result.tests_passed?? ''), acceptance_met: result.acceptance_met || '', error: result.error || ''}) if (result.status === 'failed') {failedIds.add(result.id) console.log(` [${result.id}] ${result.title} → FAILED: ${result.error}`)} else {console.log(` [${result.id}] ${result.title} → COMPLETED`)}} // 8. Cleanup temporary wave CSVs Bash(`rm -f "${sessionFolder}/wave-${wave}.csv" "${sessionFolder}/wave-${wave}-results.csv"`) console.log(` Wave ${wave} done: ${waveResults.filter(r => r.status === 'completed').length} completed, ${waveResults.filter(r => r.status === 'failed').length} failed`)} ``
2. **Instruction Template Builder** `` function buildInstructionTemplate(sessionFolder, wave) {return ` ``

## TASK ASSIGNMENT

### MANDATORY FIRST STEPS

1. Read shared discoveries: ${sessionFolder}/discoveries.ndjson (if exists, skip if not)
2. Read project context:.workflow/project-tech.json (if exists)

---

## Your Task

**Task ID**: {id} **Title**: {title} **Description**: {description} **Scope**: {scope}

### Implementation Hints & Reference Files

{hints}

> Format: ` || <ref_file1>;<ref_file2>`. Read ALL reference files (after ||) before starting implementation. Apply tips (before ||) as implementation guidance.

### Execution Directives

{execution_directives}

> Commands to run for verification, tool restrictions, or environment requirements. Follow these constraints during and after implementation.

### Test Cases

{test}

### Acceptance Criteria

{acceptance_criteria}

### Previous Tasks' Findings (Context)

{prev_context}

---

## Execution Protocol

1. **Read references**: Parse {hints} — read all files listed after `||` to understand existing patterns
2. **Read discoveries**: Load ${sessionFolder}/discoveries.ndjson for shared exploration findings
3. **Use context**: Apply previous tasks' findings from prev_context above
4. **Stay in scope**: ONLY create/modify files within {scope} — do NOT touch files outside this boundary
5. **Apply hints**: Follow implementation tips from {hints} (before `||`)
6. **Execute**: Implement the task as described
7. **Write tests**: Implement the test cases defined above
8. **Run directives**: Execute commands from {execution_directives} to verify your work
9. **Verify acceptance**: Ensure all acceptance criteria are met before reporting completion
10. **Share discoveries**: Append exploration findings to shared board: ```bash echo '{"ts":"","worker":"{id}","type":"","data":{...}}' >> ${sessionFolder}/discoveries.ndjson ```
11. **Report result**: Return JSON via report_agent_job_result

### Discovery Types to Share

- `code_pattern`: {name, file, description} — reusable patterns found
- `integration_point`: {file, description, exports[]} — module connection points
- `convention`: {naming, imports, formatting} — code style conventions
- `blocker`: {issue, severity, impact} — blocking issues encountered
- `tech_stack`: {runtime, framework, language} — project technology stack
- `test_command`: {command, scope, description} — test commands discovered

---

## Output (report_agent_job_result)

Return JSON: {"id": "{id}", "status": "completed" | "failed", "findings": "Key discoveries and implementation notes (max 500 chars)", "files_modified": ["path1", "path2"], "tests_passed": true | false, "acceptance_met": "Summary of which acceptance criteria were met/unmet", "error": ""}

**IMPORTANT**: Set status to "completed" ONLY if:

- All test cases pass
- All acceptance criteria are met Otherwise set status to "failed" with details in error field. `} ``

1. **Master CSV Update Helper** `` function updateMasterCsvRow(sessionFolder, taskId, updates) {const csvPath = `${sessionFolder}/tasks.csv` const content = Read(csvPath) const lines = content.split('\n') const header = lines[0].split(',') for (let i = 1; i < lines.length; i++) {const cells = parseCsvLine(lines[i]) if (cells[0] === taskId || cells[0] === `"${taskId}"`) {// Update specified columns for (const [col, val] of Object.entries(updates)) {const colIdx = header.indexOf(col) if (colIdx >= 0) {cells[colIdx] = `"${String(val).replace(/"/g, '""')}"`}} lines[i] = cells.join(',') break}} Write(csvPath, lines.join('\n'))} ``

**Success Criteria**: All waves executed in order, each wave's results merged into master CSV before next wave starts, dependent tasks skipped when predecessor failed, discoveries.ndjson accumulated across all waves.

---

### Phase 3: Results Aggregation

**Objective**: Generate final results and human-readable report.

**Steps**:

1. **Export results.csv** `` const masterCsv = Read(`${sessionFolder}/tasks.csv`) // results.csv = master CSV (already has all results populated) Write(`${sessionFolder}/results.csv`, masterCsv) ``
2. **Generate context.md** `` const tasks = parseCsv(masterCsv) const completed = tasks.filter(t => t.status === 'completed') const failed = tasks.filter(t => t.status === 'failed') const skipped = tasks.filter(t => t.status === 'skipped') const contextContent = `# CSV Batch Execution Report ``

**Session**: ${sessionId} **Requirement**: ${requirement} **Completed**: ${getUtc8ISOString()} **Waves**: ${maxWave} | **Concurrency**: ${maxConcurrency}

## Wave Execution

${Array.from({length: maxWave}, (_, i) => i + 1).map(w => {const waveTasks = tasks.filter(t => parseInt(t.wave) === w) return `### Wave ${w} ${waveTasks.map(t =>`- **[${t.id}] ${t.title}**: ${t.status}${t.tests_passed?

1. Start Immediately: First action is session initialization, then Phase 1
2. Wave Order is Sacred: Never execute wave N before wave N-1 completes and results are merged
3. CSV is Source of Truth: Master tasks.csv holds all state — always read before wave, always write after
4. Context Propagation: prev_context built from master CSV, not from memory
5. Discovery Board is Append-Only: Never clear, modify, or recreate discoveries.ndjson
6. Skip on Failure: If a dependency failed, skip the dependent task (don't attempt)
7. Cleanup Temp Files: Remove wave-{N}.csv and wave-{N}-results.csv after results are merged
8. DO NOT STOP: Continuous execution until all waves complete or all remaining tasks are skipped

Task Design

• Granularity: 3-10 tasks optimal; too many = overhead, too few = no parallelism benefit
• Minimize Cross-Wave Deps: More tasks in wave 1 = more parallelism
• Specific Descriptions: Agent sees only its CSV row + prev_context — make description self-contained
• Context From ≠ Deps: deps = execution order constraint; context_from = information flow. A task can have context_from without deps (it just reads previous findings but doesn't require them to be done first in its wave)
• Concurrency Tuning: -c 1 for serial execution (maximum context sharing); -c 8 for I/O-bound tasks
