Overview

Orchestrate multi-agent architecture optimization: analyze codebase structure, design refactoring plan, implement changes, validate improvements, review code quality. The pipeline has five domain roles (analyzer, designer, refactorer, validator, reviewer) mapped to CSV wave stages with an interactive review-fix cycle.

Execution Model: Hybrid -- CSV wave pipeline (primary) + individual agent spawn (secondary)

Task Classification Rules

Each task is classified by exec_mode:

exec_mode	Mechanism	Criteria
csv-wave	spawn_agents_on_csv	One-shot, structured I/O, no multi-round interaction
interactive	spawn_agent/wait/send_input/close_agent	Multi-round, revision cycles, user checkpoints

Classification Decision:

Task Property	Classification
Architecture analysis (single-pass scan)	csv-wave
Refactoring plan design (single-pass)	csv-wave
Code refactoring implementation	csv-wave
Validation (build, test, metrics)	csv-wave
Code review (single-pass)	csv-wave
Review-fix cycle (iterative revision)	interactive
User checkpoint (plan approval)	interactive
Discussion round (DISCUSS-REFACTOR, DISCUSS-REVIEW)	interactive

Implementation

Session Initialization

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

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]) : 3

const requirement = $ARGUMENTS
  .replace(/--yes|-y|--continue|--concurrency\s+\d+|-c\s+\d+/g, '')
  .trim()

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

Bash(`mkdir -p ${sessionFolder}/artifacts ${sessionFolder}/interactive ${sessionFolder}/wisdom`)

// Initialize discoveries.ndjson
Write(`${sessionFolder}/discoveries.ndjson`, '')

// Initialize wisdom
Write(`${sessionFolder}/wisdom/patterns.md`, '# Patterns & Conventions\n')

---

Phase 0: Pre-Wave Interactive (Requirement Clarification)

Objective: Parse user task, detect architecture scope, clarify ambiguities, prepare for decomposition.

Workflow:

1. Parse user task description from $ARGUMENTS

2. Check for existing sessions (continue mode):

   • Scan .workflow/.csv-wave/tao-*/tasks.csv for sessions with pending tasks
   • If --continue: resume the specified or most recent session, skip to Phase 2
   • If active session found: ask user whether to resume or start new

3. Identify architecture optimization target:

Signal	Target
Specific file/module mentioned	Scoped refactoring
"coupling", "dependency", "structure", generic	Full architecture analysis
Specific issue (cycles, God Class, duplication)	Targeted issue resolution

4. Clarify if ambiguous (skip if AUTO_YES):

   AskUserQuestion({
     questions: [{
       question: "Please confirm the architecture optimization scope:",
       header: "Architecture Scope",
       multiSelect: false,
       options: [
         { label: "Proceed as described", description: "Scope is clear" },
         { label: "Narrow scope", description: "Specify modules/files to focus on" },
         { label: "Add constraints", description: "Exclude areas, set priorities" }
       ]
     }]
   })
   

5. Output: Refined requirement string for Phase 1

Success Criteria:

• Refined requirements available for Phase 1 decomposition
• Existing session detected and handled if applicable

---

Phase 1: Requirement -> CSV + Classification

Objective: Decompose architecture optimization task into the 5-stage pipeline tasks, assign waves, generate tasks.csv.

Decomposition Rules:

1. Stage mapping -- architecture optimization always follows this pipeline:

Stage	Role	Task Prefix	Wave	Description
1	analyzer	ANALYZE	1	Scan codebase, identify structural issues, produce baseline metrics
2	designer	DESIGN	2	Design refactoring plan from architecture report
3	refactorer	REFACTOR	3	Implement refactorings per plan priority
4a	validator	VALIDATE	4	Validate build, tests, metrics, API compatibility
4b	reviewer	REVIEW	4	Review refactoring code for correctness and patterns

2. Single-pipeline decomposition: Generate one task per stage with sequential dependencies:

   • ANALYZE-001 (wave 1, no deps)
   • DESIGN-001 (wave 2, deps: ANALYZE-001)
   • REFACTOR-001 (wave 3, deps: DESIGN-001)
   • VALIDATE-001 (wave 4, deps: REFACTOR-001)
   • REVIEW-001 (wave 4, deps: REFACTOR-001)

3. Description enrichment: Each task description must be self-contained with:

   • Clear goal statement
   • Input artifacts to read
   • Output artifacts to produce
   • Success criteria
   • Session folder path

Classification Rules:

Task Property	exec_mode
ANALYZE, DESIGN, REFACTOR, VALIDATE, REVIEW (initial pass)	csv-wave
FIX tasks (review-fix cycle)	interactive (handled by fix-cycle-handler agent)

Wave Computation: Kahn's BFS topological sort with depth tracking (csv-wave tasks only).

User Validation: Display task breakdown with wave + exec_mode assignment (skip if AUTO_YES).

Success Criteria:

• tasks.csv created with valid schema, wave, and exec_mode assignments
• task-analysis.json written with scope and pipeline config
• No circular dependencies
• User approved (or AUTO_YES)

Phase 2: Wave Execution Engine (Extended)

Objective: Execute tasks wave-by-wave with hybrid mechanism support and cross-wave context propagation.

const masterCsv = Read(`${sessionFolder}/tasks.csv`)
let tasks = parseCsv(masterCsv)
const maxWave = Math.max(...tasks.map(t => t.wave))

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

  // 1. Separate tasks by exec_mode
  const waveTasks = tasks.filter(t => t.wave === wave && t.status === 'pending')
  const csvTasks = waveTasks.filter(t => t.exec_mode === 'csv-wave')
  const interactiveTasks = waveTasks.filter(t => t.exec_mode === 'interactive')

  // 2. Check dependencies -- skip tasks whose deps failed
  for (const task of waveTasks) {
    const depIds = (task.deps || '').split(';').filter(Boolean)
    const depStatuses = depIds.map(id => tasks.find(t => t.id === id)?.status)
    if (depStatuses.some(s => s === 'failed' || s === 'skipped')) {
      task.status = 'skipped'
      task.error = `Dependency failed: ${depIds.filter((id, i) =>
        ['failed','skipped'].includes(depStatuses[i])).join(', ')}`
    }
  }

  // 3. Execute pre-wave interactive tasks (if any)
  for (const task of interactiveTasks.filter(t => t.status === 'pending')) {
    // Determine agent file based on task type
    const agentFile = task.id.startsWith('FIX') ? 'agents/fix-cycle-handler.md' : 'agents/plan-reviewer.md'
    Read(agentFile)

    const agent = spawn_agent({
      message: `## TASK ASSIGNMENT\n\n### MANDATORY FIRST STEPS\n1. Read: ${agentFile}\n2. Read: ${sessionFolder}/discoveries.ndjson\n3.

    })
    const result = wait({ ids: [agent], timeout_ms: 600000 })
    if (result.timed_out) {
      send_input({ id: agent, message: "Please finalize and output current findings." })
      wait({ ids: [agent], timeout_ms: 120000 })
    }
    Write(`${sessionFolder}/interactive/${task.id}-result.json`, JSON.stringify({
      task_id: task.id, status: "completed", findings: parseFindings(result),
      timestamp: getUtc8ISOString()
    }))
    close_agent({ id: agent })
    task.status = 'completed'
    task.findings = parseFindings(result)
  }

  // 4. Build prev_context for csv-wave tasks
  const pendingCsvTasks = csvTasks.filter(t => t.status === 'pending')
  for (const task of pendingCsvTasks) {
    task.prev_context = buildPrevContext(task, tasks)
  }

  if (pendingCsvTasks.length > 0) {
    // 5. Write wave CSV
    Write(`${sessionFolder}/wave-${wave}.csv`, toCsv(pendingCsvTasks))

    // 6. Determine instruction -- read from instructions/agent-instruction.md
    Read('instructions/agent-instruction.md')

    // 7. Execute wave via spawn_agents_on_csv
    spawn_agents_on_csv({
      csv_path: `${sessionFolder}/wave-${wave}.csv`,
      id_column: "id",
      instruction: archOptInstruction,  // from instructions/agent-instruction.md
      max_concurrency: maxConcurrency,
      max_runtime_seconds: 900,
      output_csv_path: `${sessionFolder}/wave-${wave}-results.csv`,
      output_schema: {
        type: "object",
        properties: {
          id: { type: "string" },
          status: { type: "string", enum: ["completed", "failed"] },

          artifacts_produced: { type: "string" },
          error: { type: "string" }
        }
      }
    })

    // 8. Merge results into master CSV
    const results = parseCsv(Read(`${sessionFolder}/wave-${wave}-results.csv`))
    for (const r of results) {
      const t = tasks.find(t => t.id === r.id)
      if (t) Object.assign(t, r)
    }
  }

  // 9. Update master CSV
  Write(`${sessionFolder}/tasks.csv`, toCsv(tasks))

  // 10. Cleanup temp files
  Bash(`rm -f ${sessionFolder}/wave-${wave}.csv ${sessionFolder}/wave-${wave}-results.csv`)

  // 11. Post-wave: check for review-fix cycle
  const validateTask = tasks.find(t => t.id.startsWith('VALIDATE') && t.wave === wave)
  const reviewTask = tasks.find(t => t.id.startsWith('REVIEW') && t.wave === wave)

  if ((validateTask?.verdict === 'FAIL' || reviewTask?.verdict === 'REVISE' || reviewTask?.verdict === 'REJECT')) {
    const fixCycleCount = tasks.filter(t => t.id.startsWith('FIX')).length
    if (fixCycleCount < 3) {
      // Create FIX task, add to tasks, re-run refactor -> validate+review cycle
      const fixId = `FIX-${String(fixCycleCount + 1).padStart(3, '0')}`
      const feedback = [validateTask?.error, reviewTask?.findings].filter(Boolean).join('\n')
      tasks.push({
        id: fixId, title: `Fix issues from review/validation cycle ${fixCycleCount + 1}`,
        description: `Fix issues found:\n${feedback}`,
        role: 'refactorer', issue_type: '', priority: 'P0', target_files: '',
        deps: '', context_from: '', exec_mode: 'interactive',
        wave: wave + 1, status: 'pending', findings: '', verdict: '',
        artifacts_produced: '', error: ''
      })
    }
  }

  // 12. Display wave summary
  const completed = waveTasks.filter(t => t.status === 'completed').length
  const failed = waveTasks.filter(t => t.status === 'failed').length
  const skipped = waveTasks.filter(t => t.status === 'skipped').length
  console.log(`Wave ${wave} Complete: ${completed} completed, ${failed} failed, ${skipped} skipped`)
}

Success Criteria:

• All waves executed in order
• Both csv-wave and interactive tasks handled per wave
• Each wave's results merged into master CSV before next wave starts
• Dependent tasks skipped when predecessor failed
• Review-fix cycle handled with max 3 iterations
• discoveries.ndjson accumulated across all waves and mechanisms

Phase 3: Post-Wave Interactive (Completion Action)

Objective: Pipeline completion report with architecture improvement metrics and interactive completion choice.

// 1. Generate pipeline summary
const tasks = parseCsv(Read(`${sessionFolder}/tasks.csv`))
const completed = tasks.filter(t => t.status === 'completed')
const failed = tasks.filter(t => t.status === 'failed')

// 2. Load improvement metrics from validation results
let improvements = ''
try {
  const validation = JSON.parse(Read(`${sessionFolder}/artifacts/validation-results.json`))
  improvements = `Architecture Improvements:\n${validation.dimensions.map(d =>
    `  ${d.name}: ${d.baseline} -> ${d.current} (${d.improvement})`).join('\n')}`
} catch {}

console.log(`

}

Success Criteria:

• Post-wave interactive processing complete
• User informed of results and improvement metrics

Phase 4: Results Aggregation

Objective: Generate final results and human-readable report.

// 1. Export results.csv
Bash(`cp ${sessionFolder}/tasks.csv ${sessionFolder}/results.csv`)

// 2. Generate context.md
const tasks = parseCsv(Read(`${sessionFolder}/tasks.csv`))
let contextMd = `# Architecture Optimization Report\n\n`
contextMd += `**Session**: ${sessionId}\n`
contextMd += `**Date**: ${getUtc8ISOString().substring(0, 10)}\n\n`

contextMd += `## Summary\n`
contextMd += `| Status | Count |\n|--------|-------|\n`
contextMd += `| Completed | ${tasks.filter(t => t.status === 'completed').length} |\n`
contextMd += `| Failed | ${tasks.filter(t => t.status === 'failed').length} |\n`
contextMd += `| Skipped | ${tasks.filter(t => t.status === 'skipped').length} |\n\n`

contextMd += `## Deliverables\n\n`
contextMd += `| Artifact | Path |\n|----------|------|\n`
contextMd += `| Architecture Baseline | artifacts/architecture-baseline.json |\n`
contextMd += `| Architecture Report | artifacts/architecture-report.md |\n`
contextMd += `| Refactoring Plan | artifacts/refactoring-plan.md |\n`
contextMd += `| Validation Results | artifacts/validation-results.json |\n`
contextMd += `| Review Report | artifacts/review-report.md |\n\n`

const maxWave = Math.max(...tasks.map(t => t.wave))
contextMd += `## Wave Execution\n\n`
for (let w = 1; w <= maxWave; w++) {
  const waveTasks = tasks.filter(t => t.wave === w)
  contextMd += `### Wave ${w}\n\n`
  for (const t of waveTasks) {
    const icon = t.status === 'completed' ? '[DONE]' : t.status === 'failed' ? '[FAIL]' : '[SKIP]'
    contextMd += `${icon} **${t.title}** [${t.role}] ${t.verdict ? `(${t.verdict})` : ''} ${t.findings || ''}\n\n`
  }
}

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

console.log(`Results exported to: ${sessionFolder}/results.csv`)
console.log(`Report generated at: ${sessionFolder}/context.md`)

Success Criteria:

• results.csv exported (all tasks, both modes)
• context.md generated with deliverables list
• Summary displayed to user

Shared Discovery Board Protocol

All agents (csv-wave and interactive) share a single discoveries.ndjson file for cross-task knowledge exchange.

Format: One JSON object per line (NDJSON):

{"ts":"2026-03-08T10:00:00Z","worker":"ANALYZE-001","type":"cycle_found","data":{"modules":["auth","user"],"depth":2,"description":"Circular dependency between auth and user modules"}}
{"ts":"2026-03-08T10:05:00Z","worker":"REFACTOR-001","type":"file_modified","data":{"file":"src/auth/index.ts","change":"Extracted interface to break cycle","lines_added":15}}

Discovery Types:

Type	Data Schema	Description
cycle_found	{modules, depth, description}	Circular dependency detected
god_class_found	{file, loc, methods, description}	God Class/Module identified
coupling_issue	{module, fan_in, fan_out, description}	High coupling detected
dead_code_found	{file, type, description}	Dead code or dead export found
file_modified	{file, change, lines_added}	File change recorded
pattern_found	{pattern_name, location, description}	Code pattern identified
metric_measured	{metric, value, unit, module}	Architecture metric measured
artifact_produced	{name, path, producer, type}	Deliverable created

Protocol:

1. Agents MUST read discoveries.ndjson at start of execution
2. Agents MUST append relevant discoveries during execution
3. Agents MUST NOT modify or delete existing entries
4. Deduplication by {type, data.file} or {type, data.modules} key

Error Handling

Error	Resolution
Circular dependency in tasks	Detect in wave computation, abort with error message
CSV agent timeout	Mark as failed in results, continue with wave
CSV agent failed	Mark as failed, skip dependent tasks in later waves
Interactive agent timeout	Urge convergence via send_input, then close if still timed out
Interactive agent failed	Mark as failed, skip dependents
All agents in wave failed	Log error, offer retry or abort
CSV parse error	Validate CSV format before execution, show line number
discoveries.ndjson corrupt	Ignore malformed lines, continue with valid entries
Review-fix cycle exceeds 3 iterations	Escalate to user with summary of remaining issues
Validation fails on build	Create FIX task with compilation error details
Architecture baseline unavailable	Fall back to static analysis estimates
Continue mode: no session found	List available sessions, prompt user to select

Core Rules

1. Start Immediately: First action is session initialization, then Phase 0/1
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 (both csv-wave and interactive)
4. CSV First: Default to csv-wave for tasks; only use interactive when interaction pattern requires it
5. Context Propagation: prev_context built from master CSV, not from memory
6. Discovery Board is Append-Only: Never clear, modify, or recreate discoveries.ndjson -- both mechanisms share it
7. Skip on Failure: If a dependency failed, skip the dependent task (regardless of mechanism)
8. Max 3 Fix Cycles: Review-fix cycle capped at 3 iterations; escalate to user after
9. Cleanup Temp Files: Remove wave-{N}.csv after results are merged
10. DO NOT STOP: Continuous execution until all waves complete or all remaining tasks are skipped
