Workflow Test-Fix Cycle

End-to-end test-fix workflow pipeline: generate test sessions with progressive layers (L0-L3), AI code validation, and task generation (Phase 1), then execute iterative fix cycles with adaptive strategy engine until pass rate >= 95% (Phase 2).

Key Design Principles

1. Two-Phase Pipeline: Generation (Phase 1) creates session + tasks, Execution (Phase 2) runs iterative fix cycles
2. Pure Orchestrator: Dispatch to phase docs, parse outputs, pass context between phases
3. Phase 1 Auto-Continue: Sub-phases within Phase 1 run autonomously
4. Subagent Lifecycle: Explicit lifecycle management with spawn_agent → wait_agent → close_agent
5. Progressive Test Layers: L0 (Static) → L1 (Unit) → L2 (Integration) → L3 (E2E)
6. AI Code Issue Detection: Validates against common AI-generated code problems
7. Intelligent Strategy Engine: conservative → aggressive → surgical based on iteration context
8. CLI Fallback Chain: Gemini → Qwen → Codex for analysis resilience
9. Progressive Testing: Affected tests during iterations, full suite for final validation
10. Role Path Loading: Subagent roles loaded via path reference in MANDATORY FIRST STEPS

Auto Mode

Phase 1 generates test session and tasks. Phase 2 executes iterative fix cycles until pass rate >= 95% or max iterations reached. Between Phase 1 and Phase 2, you MUST stop and wait for user confirmation before proceeding to execution. Phase 2 runs autonomously once approved.

Subagent API Reference

spawn_agent

Create a new subagent with task assignment.

javascript
const agentId = spawn_agent({
  agent_type: "{agent_type}",
  message: `
## TASK ASSIGNMENT

### MANDATORY FIRST STEPS (Agent Execute)
1. Run: `ccw spec load --category "planning execution"`

## TASK CONTEXT
${taskContext}

## DELIVERABLES
${deliverables}
`
})

wait_agent

Get results from subagent (only way to retrieve results).

javascript
const result = wait_agent({
  timeout_ms: 1800000  // 30 minutes
})

if (result.timed_out) {
  followup_task({ target: agentId, message: "STATUS_CHECK: Report current progress, findings so far, and estimated remaining work." })
  const status = wait_agent({ timeout_ms: 180000 })  // 3 min
  if (status.timed_out) {
    followup_task({ target: agentId, message: "FINALIZE: Output all current findings immediately. Time limit reached.", interrupt: true })
    const forced = wait_agent({ timeout_ms: 180000 })  // 3 min
    if (forced.timed_out) {
      close_agent({ target: agentId })
    }
  }
}

followup_task

Assign new work to active subagent (for clarification or follow-up).

javascript
followup_task({
  target: agentId,
  message: `
## CLARIFICATION ANSWERS
${answers}

## NEXT STEP
Continue with plan generation.
`
})

close_agent

Clean up subagent resources (irreversible).

javascript
close_agent({ target: agentId })

Usage

workflow-test-fix-cycle <input> [options]

# Input (Phase 1 - Test Generation)
source-session-id    WFS-* session ID (Session Mode - test validation for completed implementation)
feature description  Text description of what to test (Prompt Mode)
/path/to/file.md     Path to requirements file (Prompt Mode)

# Options (Phase 2 - Cycle Execution)
--max-iterations=N   Custom iteration limit (default: 10)

# Examples
workflow-test-fix-cycle WFS-user-auth-v2                                              # Session Mode
workflow-test-fix-cycle "Test the user authentication API endpoints in src/auth/api.ts" # Prompt Mode - text
workflow-test-fix-cycle ./docs/api-requirements.md                                     # Prompt Mode - file
workflow-test-fix-cycle "Test user registration" --max-iterations=15                    # With custom iterations

# Resume (Phase 2 only - session already created)
workflow-test-fix-cycle --resume-session="WFS-test-user-auth"                          # Resume interrupted session

Quality Gate: Test pass rate >= 95% (criticality-aware) or 100% Max Iterations: 10 (default, adjustable) CLI Tools: Gemini → Qwen → Codex (fallback chain)

Test Strategy Overview

Progressive Test Layers (L0-L3):

| Layer | Name | Focus | |-------|------|-------| | L0 | Static Analysis | Compilation, imports, types, AI code issues | | L1 | Unit Tests | Function/class behavior (happy/negative/edge cases) | | L2 | Integration Tests | Component interactions, API contracts, failure modes | | L3 | E2E Tests | User journeys, critical paths (optional) |

Key Features:

• AI Code Issue Detection - Validates against common AI-generated code problems (hallucinated imports, placeholder code, mock leakage, etc.)
• Project Type Detection - Applies appropriate test templates (React, Node API, CLI, Library, etc.)
• Quality Gates - IMPL-001.3 (code validation) and IMPL-001.5 (test quality) ensure high standards

Detailed specifications: See the test-task-generate workflow tool for complete L0-L3 requirements and quality thresholds.

Execution Flow

  ├─ resume mode → Skip to Phase 2
  │
  └─ session/prompt mode → Phase 1
       │
Phase 1: Test-Fix Generation (phases/01-test-fix-gen.md)
  ├─ Sub-phase 1.1: Create Test Session → testSessionId
  ├─ Sub-phase 1.2: Gather Test Context (spawn_agent) → contextPath
  ├─ Sub-phase 1.3: Test Generation Analysis (spawn_agent → Gemini) → TEST_ANALYSIS_RESULTS.md
  ├─ Sub-phase 1.4: Generate Test Tasks (spawn_agent) → IMPL-*.json, IMPL_PLAN.md, TODO_LIST.md
  └─ Sub-phase 1.5: Phase 1 Summary
       │
  ⛔ MANDATORY CONFIRMATION GATE
  │   Present plan summary → request_user_input → User approves/cancels
  │   NEVER auto-proceed to Phase 2
       │
Phase 2: Test-Cycle Execution (phases/02-test-cycle-execute.md)
  ├─ Discovery: Load session, tasks, iteration state
  ├─ Main Loop (for each task):
  │   ├─ Execute → Test → Calculate pass_rate
  │   ├─ 100% → SUCCESS: Next task
  │   ├─ 95-99% + low criticality → PARTIAL SUCCESS: Approve
  │   └─ <95% → Fix Loop:
  │       ├─ Select strategy: conservative/aggressive/surgical
  │       ├─ spawn_agent(@cli-planning-agent) → IMPL-fix-N.json
  │       ├─ spawn_agent(@test-fix-agent) → Apply fix & re-test
  │       └─ Re-test → Back to decision
  └─ Completion: Final validation → Summary → Sync session state → Auto-complete session

Core Rules

1. Start Immediately: First action is functions.update_plan initialization
2. No Preliminary Analysis: Do not read files before Phase 1
3. Parse Every Output: Extract data from each phase/sub-phase for the next
4. Within-Phase Auto-Continue: Sub-phases within a phase run automatically; Phase 2 iterations run automatically once started
5. Phase Loading: Read phase doc on-demand (phases/01-*.md, phases/02-*.md)
6. Task Attachment Model: Sub-tasks ATTACH → execute → COLLAPSE
7. MANDATORY CONFIRMATION GATE: After Phase 1 completes, you MUST stop and present the generated plan to the user. Wait for explicit user approval via request_user_input before starting Phase 2. NEVER auto-proceed from Phase 1 to Phase 2
8. Phase 2 Continuous: Once user approves, Phase 2 runs continuously until pass rate >= 95% or max iterations reached
9. Explicit Lifecycle: Always close_agent after wait_agent completes to free resources

Phase Execution

Phase 1: Test-Fix Generation

Read: phases/01-test-fix-gen.md

5 sub-phases that create a test session and generate task JSONs:

1. Create Test Session → testSessionId
2. Gather Test Context (spawn_agent → wait_agent → close_agent) → contextPath
3. Test Generation Analysis (spawn_agent → wait_agent → close_agent) → TEST_ANALYSIS_RESULTS.md
4. Generate Test Tasks (spawn_agent → wait_agent → close_agent) → IMPL-001.json, IMPL-001.3.json, IMPL-001.5.json, IMPL-002.json, IMPL_PLAN.md, TODO_LIST.md
5. Phase 1 Summary → ⛔ MANDATORY: Present plan and wait for user confirmation before Phase 2

Agents Used (via spawn_agent):

• test_context_search_agent (agent_type: test_context_search_agent) - Context gathering (Session Mode)
• context_search_agent (agent_type: context_search_agent) - Context gathering (Prompt Mode)
• cli_execution_agent (agent_type: cli_execution_agent) - Test analysis with Gemini
• action_planning_agent (agent_type: action_planning_agent) - Task JSON generation

Phase 2: Test-Cycle Execution

Read: phases/02-test-cycle-execute.md

3-stage iterative execution with adaptive strategy:

1. Discovery - Load session, tasks, iteration state
2. Main Loop - Execute tasks → Test → Analyze failures → Fix → Re-test
3. Completion - Final validation → Summary → Auto-complete session

Agents Used (via spawn_agent):

• cli_planning_agent (agent_type: cli_planning_agent) - Failure analysis, root cause extraction, fix task generation
• test_fix_agent (agent_type: test_fix_agent) - Test execution, code fixes, criticality assignment

Strategy Engine: conservative (iteration 1-2) → aggressive (pass >80%) → surgical (regression)

Progress Tracking

Initialization (MANDATORY)

javascript
// Initialize progress tracking after input parsing
functions.update_plan([
  { id: "phase-1", title: "Phase 1: Test-Fix Generation", status: "in_progress" },
  { id: "phase-2", title: "Phase 2: Test-Cycle Execution", status: "pending" }
])

Phase Transitions

javascript
// After Phase 1 completes (before mandatory confirmation gate)
functions.update_plan([
  { id: "phase-1", status: "completed" },
  { id: "phase-2", status: "in_progress" }
])

// After Phase 2 completes (pass rate >= 95% or max iterations)
functions.update_plan([{ id: "phase-2", status: "completed" }])

Resume Mode

javascript
// When --resume-session skips Phase 1
functions.update_plan([
  { id: "phase-1", title: "Phase 1: Test-Fix Generation", status: "completed" },
  { id: "phase-2", title: "Phase 2: Test-Cycle Execution", status: "in_progress" }
])

Error Handling

| Phase | Scenario | Action | |-------|----------|--------| | 1.1 | Source session not found (session mode) | Return error with session ID | | 1.1 | No completed IMPL tasks (session mode) | Return error, source incomplete | | 1.2 | Context gathering failed | Return error, check source artifacts | | 1.2 | Agent timeout | Retry with extended timeout, close_agent, then return error | | 1.3 | Gemini analysis failed | Return error, check context package | | 1.4 | Task generation failed | Retry once, then return error | | 2 | Test execution error | Log, retry with error context | | 2 | CLI analysis failure | Fallback: Gemini → Qwen → Codex → manual | | 2 | Agent execution error | Save state, close_agent, retry with simplified context | | 2 | Max iterations reached | Generate failure report, mark blocked | | 2 | Regression detected | Rollback last fix, switch to surgical strategy | | 2 | Stuck tests detected | Continue with alternative strategy, document in failure report |

Lifecycle Error Handling:

javascript
try {
  const agentId = spawn_agent({ message: "..." });
  const result = wait_agent({ timeout_ms: 1800000 });  // 30 minutes
  // ... process result ...
  close_agent({ target: agentId });
} catch (error) {
  if (agentId) close_agent({ target: agentId });
  throw error;
}

Coordinator Checklist

Phase 1 (Generation):

• Detect input type (session ID / description / file path / resume)
• Initialize functions.update_plan with 2 top-level phases
• Read phases/01-test-fix-gen.md for detailed sub-phase execution
• Execute 5 sub-phases with spawn_agent → wait_agent → close_agent lifecycle
• Verify all Phase 1 outputs (4+ task JSONs, IMPL_PLAN.md, TODO_LIST.md)
• Ensure all agents are closed after each sub-phase completes
• ⛔ MANDATORY: Present plan summary and request_user_input for confirmation
• Show: session ID, task count, test layers, quality gates
• Options: "Proceed to Execution" / "Review Plan" / "Cancel"
• If "Cancel" → return, do NOT start Phase 2
• If "Review Plan" → display IMPL_PLAN.md, then return
• Only proceed to Phase 2 if user selects "Proceed to Execution"

Phase 2 (Execution):

• Read phases/02-test-cycle-execute.md for detailed execution logic
• Load session state and task queue
• Execute iterative test-fix cycles with spawn_agent → wait_agent → close_agent
• Track iterations via functions.update_plan
• Auto-complete session on success (pass rate >= 95%)
• Ensure all agents are closed after each iteration

Resume Mode:

• If --resume-session provided, skip Phase 1
• Load existing session directly into Phase 2
