Overview

Explore-first wave-based pipeline using spawn_agents_on_csv. Two-stage CSV execution: explore.csv (codebase discovery) → tasks.csv (implementation), with cross-phase context propagation via context_from linking (E* → T*).

Core workflow: Decompose → [Confirm] → Wave Explore → Synthesize & Plan → [Confirm] → Wave Execute → Aggregate

Per-Wave CSV (Temporary)

Each wave generates a temporary CSV with an extra prev_context column.

Explore wave: explore-wave-{N}.csv — same columns as explore.csv (no prev_context, explorations are independent).

Execute wave: task-wave-{N}.csv — all task columns + prev_context:

id,title,description,test,acceptance_criteria,scope,hints,execution_directives,deps,context_from,wave,prev_context
"T2","Implement core","Implement core auth logic","Unit test: login returns token","Login flow works end-to-end","src/auth/**","Reuse BaseService || src/services/Base.ts","npm test -- --grep auth","T1","E1;E2;T1","2","[Explore architecture] Found BaseService pattern in src/services/\n[Task T1] Created types at src/types/auth.ts"

The prev_context column is built from context_from by looking up completed rows' findings in both explore.csv (E*) and tasks.csv (T*).

Phase 1: Requirement → explore.csv

Objective: Analyze requirement complexity, select exploration angles, generate explore.csv.

Steps:

1. Analyze & Decompose

   Bash({
     command: `ccw cli -p "PURPOSE: Analyze requirement complexity and select 1-4 exploration angles for codebase discovery before implementation.
   

TASK: • Classify requirement type (feature/bugfix/refactor/security/performance) • Assess complexity (Low: 1 angle, Medium: 2-3, High: 3-4) • Select exploration angles from: architecture, dependencies, integration-points, testing, patterns, security, performance, state-management, error-handling, edge-cases • For each angle, define focus keywords and what to discover MODE: analysis CONTEXT: @**/* EXPECTED: JSON object: {type: string, complexity: string, angles: [{id: string, angle: string, description: string, focus: string}]}. Each angle id = E1, E2, etc. CONSTRAINTS: 1-4 angles | Angles must be distinct | Each angle must have clear focus

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 → { type, complexity, angles[] }

2. **Generate explore.csv**

```javascript
const header = 'id,angle,description,focus,deps,wave,status,findings,key_files,error'
const rows = angles.map(a =>
  [a.id, a.angle, a.description, a.focus, '', '1', 'pending', '', '', '']
    .map(v => `"${String(v).replace(/"/g, '""')}"`)
    .join(',')
)

Write(`${sessionFolder}/explore.csv`, [header, ...rows].join('\n'))

3. User Validation — MANDATORY CONFIRMATION GATE (skip ONLY if AUTO_YES)

   CRITICAL: You MUST stop here and wait for user confirmation before proceeding to Phase 2. DO NOT skip this step. DO NOT auto-proceed.

   if (!AUTO_YES) {
     console.log(`\n## Exploration Plan (${angles.length} angles)\n`)
     angles.forEach(a => console.log(`  - [${a.id}] ${a.angle}: ${a.focus}`))
   
     const answer = functions.request_user_input({
       questions: [{
         question: "Approve exploration angles?",
         header: "Validation",
         options: [
           { label: "Approve", description: "Proceed with wave exploration" },
           { label: "Modify", description: `Edit ${sessionFolder}/explore.csv manually, then --continue` },
           { label: "Cancel", description: "Abort" }
         ]
       }]
     })
   
     if (answer.Validation === "Modify") {
       console.log(`Edit: ${sessionFolder}/explore.csv\nResume: $workflow-lite-plan --continue`)
       return
     }   (answer. === ) {
       
     }
   }
   

Success Criteria:

• explore.csv created with 1-4 exploration angles
• User approved (or AUTO_YES)

---

Phase 2: Wave Explore (spawn_agents_on_csv)

Objective: Execute exploration via spawn_agents_on_csv. Each angle produces findings and key_files.

Steps:

1. Explore Wave Loop

   const exploreCSV = parseCsv(Read(`${sessionFolder}/explore.csv`))
   const maxExploreWave = Math.max(...exploreCSV.map(r => parseInt(r.wave)))
   
   for (let wave = 1; wave <= maxExploreWave; wave++) {
     const waveTasks = exploreCSV.filter(r =>
       parseInt(r.wave) === wave && r.status === 'pending'
     )
     if (waveTasks.length === 0) continue
   
     // Skip rows with failed dependencies
     const executableTasks = []
     for (const task of waveTasks) {
       const deps = (task.deps || '').split(';').filter(Boolean)
       if (deps.some(d => {
         const dep = exploreCSV.find(r => r.id === d)
         return !dep || dep. !== 
       })) {
         task. = 
         task. = 
         
       }
       executableTasks.(task)
     }
   
      (executableTasks. === ) 
   
     
      waveHeader = 
      waveRows = executableTasks.(
       [t., t., t., t., t., t.]
         .( 

EXPLORATION 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 Exploration

Exploration ID: {id} Angle: {angle} Description: {description} Focus: {focus}

---

Exploration Protocol

1. Read discoveries: Load ${sessionFolder}/discoveries.ndjson for shared findings
2. Explore: Search the codebase from the {angle} perspective
3. Discover: Find relevant files, patterns, integration points, constraints
4. Share discoveries: Append findings to shared board: ```bash echo '{"ts":"","worker":"{id}","type":"","data":{...}}' >> ${sessionFolder}/discoveries.ndjson ```
5. Report result: Return JSON via report_agent_job_result

What to Look For

• Existing patterns and conventions to follow
• Integration points and module boundaries
• Dependencies and constraints
• Test infrastructure and coverage
• Risks and potential blockers

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
• `tech_stack`: {framework, version, config} — technology stack details

---

Output (report_agent_job_result)

Return JSON: { "id": "{id}", "status": "completed" | "failed", "findings": "Concise summary of ${'{'}angle{'}'} discoveries (max 800 chars)", "key_files": ["relevant/file1.ts", "relevant/file2.ts"], "error": "" } ` }

**Success Criteria**:
- All explore angles executed
- explore.csv updated with findings and key_files
- discoveries.ndjson accumulated

---

### Phase 3: Synthesize & Plan → tasks.csv

**Objective**: Read exploration findings, cross-reference, resolve conflicts, generate tasks.csv with context_from linking to E* rows.

**Steps**:

1. **Synthesize Exploration Findings**

```javascript
const exploreCSV = parseCsv(Read(`${sessionFolder}/explore.csv`))
const completed = exploreCSV.filter(r => r.status === 'completed')

// Cross-reference: find shared files across angles
const fileRefs = {}
completed.forEach(r => {
  (r.key_files || '').split(';').filter(Boolean).forEach(f => {
    if (!fileRefs[f]) fileRefs[f] = []
    fileRefs[f].push({ angle: r.angle, id: r.id })
  })
})
const sharedFiles = Object.entries(fileRefs).filter(([_, refs]) => refs.length > 1)

// Build synthesis context for task decomposition
const synthesisContext = completed.map(r =>
  `[${r.id}: ${r.angle}] ${r.findings}\n  Key files: ${r.key_files || 'none'}`
).join('\n\n')

const sharedFilesContext = sharedFiles.length > 0
  ? `\nShared files (referenced by multiple angles):\n${sharedFiles.map(([f, refs]) =>
      `  ${f} ← ${refs.map(r => r.id).join(', ')}`
    ).join('\n')}`
  : ''

2. Decompose into Tasks

   Bash({
     command: `ccw cli -p "PURPOSE: Based on exploration findings, decompose requirement into 3-10 atomic execution tasks. Each task must include test cases, acceptance criteria, and link to relevant exploration findings.
   

TASK: • Use exploration findings to inform task decomposition • Each task must be self-contained with specific implementation instructions • Link tasks to exploration rows via context_from (E1, E2, etc.) • Define dependencies between tasks (T1 must finish before T2, etc.) • For each task: define test cases, acceptance criteria, scope, hints, and execution directives • Ensure same-wave tasks have non-overlapping scopes 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[]}.

• id: T1, T2, etc.
• description: what to implement (specific enough for an agent)
• test: what tests to write (e.g. 'Unit test: X returns Y')
• acceptance_criteria: what defines done (e.g. 'API returns 200')
• scope: target glob (e.g. 'src/auth/**') — non-overlapping within same wave
• hints: tips + ref files (format: 'tips || file1;file2')
• execution_directives: verification commands (e.g. 'npm test --bail')
• deps: task IDs that must complete first (T*)
• context_from: explore (E*) and task (T*) IDs whose findings are needed CONSTRAINTS: 3-10 tasks | Atomic | No circular deps | Concrete test/acceptance_criteria | Non-overlapping scopes per wave

EXPLORATION FINDINGS: ${synthesisContext} ${sharedFilesContext}

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

3. **Compute Waves & Write tasks.csv**

```javascript
const { waveAssignment, maxWave } = computeWaves(decomposedTasks)

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', '', '', '', '', ''
  ].map(cell => `"${String(cell).replace(/"/g, '""')}"`).join(',')
})

Write(`${sessionFolder}/tasks.csv`, [header, ...rows].join('\n'))

4. User Validation — MANDATORY CONFIRMATION GATE (skip ONLY if AUTO_YES)

   CRITICAL: You MUST stop here and wait for user confirmation before proceeding to Phase 4. DO NOT skip this step. DO NOT auto-proceed.

   if (!AUTO_YES) {
     console.log(`
   

Execution Plan

Explore: ${completed.length} angles completed Shared files: ${sharedFiles.length} Tasks: ${decomposedTasks.length} across ${maxWave} waves

${Array.from({length: maxWave}, (_, i) => i + 1).map(w => { const wt = decomposedTasks.filter(t => waveAssignment.get(t.id) === w) return ### Wave ${w} (${wt.length} tasks, concurrent) ${wt.map(t => - [${t.id}] ${t.title} (scope: ${t.scope}, from: ${t.context_from.join(';')})).join('\n')} }).join('\n')} `)

 const answer = functions.request_user_input({
   questions: [{
     question: `Proceed with ${decomposedTasks.length} tasks across ${maxWave} waves?`,
     header: "Confirm",
     options: [
       { label: "Execute", description: "Proceed with wave execution" },
       { label: "Modify", description: `Edit ${sessionFolder}/tasks.csv then --continue` },
       { label: "Cancel", description: "Abort" }
     ]
   }]
 })

 if (answer.Confirm === "Modify") {
   console.log(`Edit: ${sessionFolder}/tasks.csv\nResume: $workflow-lite-plan --continue`)
   return  // STOP — do not proceed to Phase 4
 } else if (answer.Confirm === "Cancel") {
   return  // STOP — do not proceed to Phase 4
 }
 // Only reach here if user selected "Execute"

}

**Success Criteria**:
- tasks.csv created with context_from linking to E* rows
- No circular dependencies
- User explicitly approved (or AUTO_YES) — Phase 4 MUST NOT start without this

---

### Phase 4: Wave Execute (spawn_agents_on_csv)

**Objective**: Execute tasks wave-by-wave via `spawn_agents_on_csv`. Each wave's prev_context is built from both explore.csv and tasks.csv.

**Steps**:

1. **Wave Loop**

```javascript
const exploreCSV = parseCsv(Read(`${sessionFolder}/explore.csv`))
const failedIds = new Set()
const skippedIds = new Set()

for (let wave = 1; wave <= maxWave; wave++) {
  console.log(`\n## Wave ${wave}/${maxWave}\n`)

  // Re-read master CSV
  const masterCsv = parseCsv(Read(`${sessionFolder}/tasks.csv`))
  const waveTasks = masterCsv.filter(row => parseInt(row.wave) === wave)

  // 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(`${sessionFolder}/tasks.csv`, task.id, {
        status: 'skipped',
        error: 'Dependency failed or skipped'
      })
      console.log(`  [${task.id}] ${task.title} → SKIPPED (dependency failed)`)
      continue
    }
    executableTasks.push(task)
  }

  if (executableTasks.length === 0) {

2. prev_context Builder (Cross-Phase)

   The key function linking exploration context to execution:

   function buildPrevContext(contextFrom, exploreCSV, tasksCSV) {
     if (!contextFrom) return 'No previous context available'
   
     const ids = contextFrom.split(';').filter(Boolean)
     const entries = []
   
     ids.forEach(id => {
       if (id.startsWith('E')) {
         // ← Look up in explore.csv (cross-phase link)
         const row = exploreCSV.find(r => r.id === id)
         if (row && row.status === 'completed' && row.findings) {
           entries.push(`[Explore ${row.angle}] ${row.findings}`)
           if (row.key_files) entries.push(`  Key files: ${row.key_files}`)
         }
       } else if (id.startsWith('T')) {
         // ← Look up in tasks.csv (same-phase link)
         const row = tasksCSV.find(r => r. === id)
          (row && row. ===  && row.) {
           entries.()
            (row.) entries.()
         }
       }
     })
   
      entries. >  ? entries.() : 
   }
   

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: `tips text || file1;file2`. Read ALL reference files (after ||) before starting. Apply tips (before ||) as guidance.

Execution Directives

{execution_directives}

Commands to run for verification, tool restrictions, or environment requirements.

Test Cases

{test}

Acceptance Criteria

{acceptance_criteria}

Previous Context (from exploration and predecessor tasks)

{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

---

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. ` }

4. Master CSV Update Helper

   function updateMasterCsvRow(csvPath, taskId, updates) {
     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] === `"${taskId}"`) {
         for (const [col, val] of Object.entries(updates)) {
           const colIdx = header.indexOf(col)
           if (colIdx >= 0) {
             cells[colIdx] = `"${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 phases

---

Phase 5: Results Aggregation

Objective: Generate final results and human-readable report.

Steps:

1. Export results.csv

   const masterCsv = Read(`${sessionFolder}/tasks.csv`)
   Write(`${sessionFolder}/results.csv`, masterCsv)
   

2. Generate context.md

   const finalTasks = parseCsv(masterCsv)
   const exploreCSV = parseCsv(Read(`${sessionFolder}/explore.csv`))
   const completed = finalTasks.filter(t => t.status === 'completed')
   const failed = finalTasks.filter(t => t.status === 'failed')
   const skipped = finalTasks.filter(t => t.status === 'skipped')
   
   const contextContent = `# Lite Planex Execution Report
   

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

---

Summary

Metric	Count
Explore Angles	${exploreCSV.length}
Total Tasks	${finalTasks.length}

Exploration Results

${exploreCSV.map(e => ### ${e.id}: ${e.angle} (${e.status}) ${e.findings || 'N/A'} Key files: ${e.key_files || 'none'}).join('\n\n')}

${[...new Set(finalTasks.flatMap(t => (t.files_modified || '').split(';')).filter(Boolean))].map(f => '- ' + f).join('\n') || 'None'} `

Write(${sessionFolder}/context.md, contextContent)

3. **Display Summary**

```javascript
console.log(`
## Lite Planex Complete

- **Session**: ${sessionId}
- **Explore**: ${exploreCSV.filter(r => r.status === 'completed').length}/${exploreCSV.length} angles
- **Tasks**: ${completed.length}/${finalTasks.length} completed, ${failed.length} failed, ${skipped.length} skipped
- **Waves**: ${maxWave}

**Results**: ${sessionFolder}/results.csv
**Report**: ${sessionFolder}/context.md
**Discoveries**: ${sessionFolder}/discoveries.ndjson
`)

4. Offer Next Steps (skip if AUTO_YES)

   if (!AUTO_YES && failed.length > 0) {
     const answer = functions.request_user_input({
       questions: [{
         question: `${failed.length} tasks failed. Next action?`,
         header: "Next Step",
         options: [
           { label: "Retry Failed", description: `Re-execute ${failed.length} failed tasks with updated context` },
           { label: "View Report", description: "Display context.md" },
           { label: "Done", description: "Complete session" }
         ]
       }]
     })
   
     if (answer['Next Step'] === "Retry Failed") {
       for (const task of failed) {
         updateMasterCsvRow(`${sessionFolder}/tasks.csv`, task.id, { status: 'pending', error: '' })
       }
       for (const task of skipped) {
         updateMasterCsvRow(`${sessionFolder}/tasks.csv`, task.id, { status: , :  })
       }
       
     }   (answer[] === ) {
       .(())
     }
   }
   

Success Criteria:

• results.csv exported
• context.md generated with full field coverage
• Summary displayed to user

Wave Computation (Kahn's BFS)

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)
      }
    }
  }

  const queue = []
  const waveAssignment = new Map()

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

   maxWave = 
   idx = 
   (idx < queue.) {
     [current, depth] = queue[idx++]
     ( next  adjList.(current)) {
       newDeg = inDegree.(next) - 
      inDegree.(next, newDeg)
       nextDepth = .(waveAssignment.(next) || , depth + )
      waveAssignment.(next, nextDepth)
       (newDeg === ) {
        queue.([next, nextDepth])
        maxWave = .(maxWave, nextDepth)
      }
    }
  }

   ( task  tasks) {
     (!waveAssignment.(task.)) {
        ()
    }
  }

   { waveAssignment, maxWave }
}

Shared Discovery Board Protocol

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

{"ts":"2026-02-28T10:00:00+08:00","worker":"E1","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":"T2","type":"integration_point","data":{"file":"src/auth/index.ts","description":"Auth module entry","exports":["authenticate","authorize"]}}

Types: code_pattern, integration_point, convention, blocker, tech_stack, test_command Rules: Read first → write immediately → deduplicate → append-only

---

Error Handling

Error	Resolution
Explore agent failure	Mark as failed in explore.csv, exclude from planning
All explores failed	Fallback: plan directly from requirement without exploration
Circular dependency	Abort wave computation, report cycle
Execute agent timeout	Mark as failed in results, continue with wave
Execute agent failed	Mark as failed, skip dependent tasks in later waves
CSV parse error	Validate CSV format before execution, show line number
discoveries.ndjson corrupt	Ignore malformed lines, continue with valid entries
Continue mode: no session	List available sessions, prompt user to select

---

Core Rules

1. Explore Before Execute: Phase 2 completes before Phase 4 starts
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 CSVs hold all state — always read before wave, always write after
4. Cross-Phase Context: prev_context built from both explore.csv (E*) and tasks.csv (T*), not from memory
5. E ↔ T Linking**: tasks.csv context_from references explore.csv rows for cross-phase context
6. Discovery Board is Append-Only: Never clear, modify, or recreate discoveries.ndjson
7. Skip on Failure: If a dependency failed, skip the dependent task (cascade)
8. Cleanup Temp Files: Remove wave CSVs after results are merged
9. MANDATORY CONFIRMATION GATES: Unless -y/--yes is set, you MUST stop and wait for user confirmation after Phase 1 (exploration plan) and Phase 3 (execution plan) before proceeding. NEVER skip these gates. Phase 4 execution MUST NOT begin until user explicitly approves
10. Continuous Within Phase: Within a phase (e.g., wave loop in Phase 4), execute continuously until all waves complete or all remaining tasks are skipped — but NEVER cross a confirmation gate without user approval

---

Best Practices

1. Exploration Angles: 1 for simple, 3-4 for complex; avoid redundant angles
2. Context Linking: Link every task to at least one explore row (E*) — exploration was done for a reason
3. Task Granularity: 3-10 tasks optimal; too many = overhead, too few = no parallelism
4. Minimize Cross-Wave Deps: More tasks in wave 1 = more parallelism
5. Specific Descriptions: Agent sees only its CSV row + prev_context — make description self-contained
6. Non-Overlapping Scopes: Same-wave tasks must not write to the same files
7. Concurrency Tuning: -c 1 for serial (max context sharing); -c 8 for I/O-bound tasks

---

Usage Recommendations

Scenario	Recommended Approach
Complex feature (unclear architecture)	$workflow-lite-plan — explore first, then plan
Simple known-pattern task	$workflow-lite-plan — skip exploration, direct execution
Independent parallel tasks	$workflow-lite-plan -c 8 — single wave, max parallelism
Diamond dependency (A→B,C→D)	$workflow-lite-plan — 3 waves with context propagation
Unknown codebase	$workflow-lite-plan — exploration phase is essential
