Verify Task $1 from EXECUTION_PLAN.md using the code verification workflow.

Context Detection

Determine working context:

1. If current working directory matches pattern */features/*:

   • PROJECT_ROOT = parent of parent of CWD (e.g., /project/features/foo → /project)
   • MODE = "feature"

2. If current working directory matches pattern */plans/greenfield*:

   • PROJECT_ROOT = parent of parent of CWD (e.g., /project/plans/greenfield → /project)
   • MODE = "greenfield"

3. Otherwise:

   • PROJECT_ROOT = current working directory
   • MODE = "greenfield-legacy"

Directory Guard (Wrong Directory Check)

Before starting, confirm EXECUTION_PLAN.md exists in the current working directory.

• If it does not exist, STOP and tell the user to cd into their project/feature directory (the one containing EXECUTION_PLAN.md) and re-run /verify-task $1.
• If plans/greenfield/EXECUTION_PLAN.md exists in the current working directory, tell the user to cd plans/greenfield and re-run /verify-task $1.

Task Context

1. Read Task $1 definition from EXECUTION_PLAN.md
2. Extract all acceptance criteria
3. Read .claude/verification-config.json from PROJECT_ROOT if it exists

If the config is missing or required commands are empty:

• Run /configure-verification
• Note the missing config in the report if verification cannot proceed

Verification Workflow

Copy this checklist and track progress:

Verify Task Progress:
- [ ] Step 1: Parse criteria from task
- [ ] Step 2: Pre-flight check (testability)
- [ ] Step 3: TDD compliance check
- [ ] Step 4: Test quality gate (optional)
- [ ] Step 5: Verify each criterion
- [ ] Step 6: Handle exit conditions
- [ ] Step 7: Generate report
- [ ] Step 8: Log to verification-log.jsonl

Follow the code-verification workflow (inline, no sub-agents):

Step 1: Parse Criteria

For each acceptance criterion, create a verification item:

Field	Value
ID	V-001, V-002, etc.
Criterion	The acceptance criterion text
Type	CODE, TEST, LINT, TYPE, BUILD, SECURITY, BROWSER:*, MANUAL, or MANUAL:DEFER
Verify	The Verify: method (test name, command, route/selector, etc.)
Evidence	Where evidence will be stored (log, screenshot, or output path)
Files	Which files to examine

If a criterion is missing a type or Verify: line:

• Infer the most likely type and verification method
• Update EXECUTION_PLAN.md to add the missing metadata
• If ambiguous, ask the human to confirm before proceeding

Step 2: Pre-flight Check

Confirm each criterion is testable:

• Clear pass/fail criteria
• Required files exist
• Verification command available (from .claude/verification-config.json)

Flag untestable criteria immediately.

Browser Tool Availability Check (SOFT BLOCK):

If any criteria are type BROWSER:*:

1. Check tool availability (fallback chain):

   • ExecuteAutomation Playwright → Browser MCP → Microsoft Playwright → Chrome DevTools

2. If at least one tool available: Continue to verification.

3. If NO browser tools available:

   • Display warning:

     ⚠️  BROWSER VERIFICATION BLOCKED
     
     Task $1 has {N} browser-based acceptance criteria but no browser
     MCP tools are available.
     
     Browser criteria:
     - {list each BROWSER:* criterion}
     
     Options:
     1. Continue anyway (browser criteria become manual verification)
     2. Stop and configure browser tools first
     

   • Use AskUserQuestion to let user choose:
     • "Continue with manual verification" → Mark browser criteria as MANUAL, proceed
     • "Stop to configure tools" → Halt verification, provide setup instructions

---

Step 3: TDD Compliance Check (Separate from Verification)

This step evaluates development process quality, not functional correctness. TDD failures are informational — they don't block task completion.

Verify that Test-Driven Development was followed:

1. Test existence check — For each acceptance criterion:

   • Locate the corresponding test(s)
   • Record test file and test name
   • If no test exists → FAIL with "Missing test for criterion"

2. Test-first check (if git history available):

   # Check if test file was committed before/with implementation
   git log --oneline --follow -- "path/to/test/file"
   git log --oneline --follow -- "path/to/impl/file"
   

   • Tests committed before or same commit as implementation → PASS
   • Tests committed after implementation → WARNING (note in report)
   • Unable to determine → SKIP (note in report)

3. Test effectiveness check — For each test:

   • Test should fail if implementation is broken/removed
   • Test name should describe expected behavior
   • Test should have meaningful assertions (not just "no errors")

TDD Compliance Report:

TDD COMPLIANCE: Task $1
-----------------------
Tests Found: X/Y criteria covered
Test-First: PASS | WARNING | UNABLE TO VERIFY
Issues:
- [Criterion] Missing test
- [Criterion] Test added after implementation
- [Criterion] Test has no meaningful assertions

If tests are missing for any criterion, stop and write tests before proceeding.

If test runner is unavailable or not configured:

• Check verification-config.json for testCommand
• If no test command: report "No test runner configured — TDD compliance cannot be assessed"
• Mark TDD check as SKIPPED (not FAIL)
• Suggest: Run /configure-verification to set up test commands

Step 4: Test Quality Gate (Optional)

This step checks whether tests are meaningful, not just present.

If .claude/verification-config.json includes commands.mutation_test, ask whether to run it for this task. If yes, prefer a scoped run (changed files or specific test paths). If mutation tests fail, mark the test-quality gate as FAIL and stop for fixes.

Otherwise, run this lightweight checklist and record PASS/WARNING:

• Each acceptance criterion has at least one assertion that checks behavior
• At least one non-happy-path or boundary case is covered when applicable
• Tests verify state changes or outputs (not just "does not throw")
• External dependencies are mocked; code under test is not

If any criterion lacks assertions or only smoke-tests behavior, mark the test-quality gate as FAIL and stop to improve tests.

Step 5: Verify Each Criterion

For each criterion:

1. Check if the criterion is met
2. Record the result:

   VERIFICATION: [V-001]
   ---------------------
   Status: PASS | FAIL | BLOCKED
   Location: [file:line or "N/A"]
   Finding: [What was found]
   Expected: [What was expected]
   Suggested Fix: [If FAIL]
   

3. If FAIL: Attempt fix, then re-verify (up to 5 attempts)
4. Track attempts to avoid repeating failed fixes

Verification method by type:

• TEST: Use config commands.test. If Verify: includes a test name or file path, run a focused test command if the test runner supports it; otherwise run the full test suite and note the limitation.

• LINT: Use config commands.lint.

• TYPE: Use config commands.typecheck.

• BUILD: Use config commands.build.

• SECURITY: Run /security-scan (or equivalent for config if defined).

• CODE: Inspect the file, export, or command indicated by Verify:.

• BROWSER:*: Use the browser-verification skill with route/selector details.

• MANUAL / MANUAL:DEFER: Attempt automation using the auto-verify skill:

  1. Invoke auto-verify skill with criterion text and available tools
  2. If PASS: Mark as verified (automated), record method used
  3. If FAIL: Show error and suggested fix, mark as manual with context
  4. If TRULY_MANUAL and tagged MANUAL:DEFER: Enqueue to deferred review queue (.claude/deferred-reviews.json). Task continues — this does NOT block. Mark checkbox with — Deferred: {key}.
  5. If TRULY_MANUAL and tagged MANUAL (blocking): List in report for human review with reason

  Report format for attempted automation:

  [V-XXX] MANUAL → AUTOMATED
  Method: {tool} ({pattern detected})
  Result: PASS | FAIL
  Duration: {ms}
  

Step 6: Exit Conditions

Stop verification loop when:

• PASS: Criterion met
• 5 attempts exhausted: Mark failed
• Same failure 3+ times: Flag for human review

Step 7: Report

TDD Issues (if any):
- [Criterion] {issue description}

Step 8: Verification Log

Append a JSON line to .claude/verification-log.jsonl for each criterion:

{
  "timestamp": "{ISO timestamp}",
  "scope": "task",
  "task_id": "$1",
  "criterion_id": "V-001",
  "type": "TEST",
  "status": "PASS",
  "evidence": ".claude/verification/task-$1.md"
}

Ensure .claude/verification/ exists before writing evidence files.

Error Handling

Situation	Action
EXECUTION_PLAN.md not found in working directory	Stop and tell user to cd into the project/feature directory containing EXECUTION_PLAN.md
Task ID $1 not found in EXECUTION_PLAN.md	Stop and report "Task $1 not found"; list available task IDs for the user
.claude/verification-config.json missing or has empty commands	Run /configure-verification automatically; if still missing, report and mark checks as SKIPPED
Test runner command fails with non-zero exit (not test failures)	Distinguish execution errors from test failures; report the execution error and mark criterion as BLOCKED
No browser MCP tools available for BROWSER:* criteria	Prompt user to continue with manual verification or stop to configure browser tools

On Success

• Check off completed criteria in EXECUTION_PLAN.md: - [ ] → - [x]
• Update .claude/phase-state.json task entry, including per-criterion results:

  {
    "tasks": {
      "$1": {
        "status": "COMPLETE",
        "completed_at": "{ISO timestamp}",
        "verification": {
          "passed": true,
          "criteria_met": "X/X",
          "tdd_compliant": true,
          "criteria": {
            "V-001": {"status": "PASS", "type": "TEST", "evidence": "..."},
            "V-002":      
          
        
      
    
  
  

On Failure

• Report which criteria failed
• Provide fix recommendations
• Do not check off incomplete criteria
• Update .claude/phase-state.json task entry and note failed criteria:

  {
    "tasks": {
      "$1": {
        "status": "IN_PROGRESS",
        "verification": {
          "passed": false,
          "criteria_met": "X/Y",
          "last_attempt": "{ISO timestamp}",
          "attempts": N,
          "failing_criteria": ["V-001", "V-003"]
        }
      }
    }
  }
