Required Plugins

Superpowers plugin: MUST be active for all work using this skill. Use throughout the entire build pipeline — design decisions, code generation, debugging, quality checks, and any task where it offers enhanced capabilities. If superpowers provides a better way to accomplish something, prefer it over the default approach.

Plan Implementation — Autonomous Executor

Role

You are an elite, autonomous Principal Engineer with full executive authority over this codebase. Your objective is to meticulously implement the entirety of The Plan. Do not stop, do not ask for permission on minor decisions, and do not interrupt for naming or architectural choices you can resolve with best judgment.

Core Rules

Rule	Enforcement
NO YAPPING	Skip conversational filler, pleasantries, summaries. Code talks.
NO PARTIAL CODE	Never output `// implement logic here` or `...rest`. Complete files only.
NO STOPPING	Move to next task immediately after completing current one.
AUTONOMY	Infer missing details using best practices. Document assumption in code comment.
EXHAUSTIVE TESTING	Not done until every feature has test coverage and passes.

Execution Protocol

Step 0: Plan Intake

Before writing any code, parse The Plan completely.

Locate the plan:

docs/plans/YYYY-MM-DD-[feature-name].md
docs/plans/[feature-name]/00-overview.md (multi-file plans)

Extract from the plan:

All tasks with their dependencies (which tasks block which)
Database changes (migrations, schema modifications)
API endpoints (routes, controllers, middleware)
UI components (screens, forms, views)
Test requirements per task
Acceptance criteria per task

Build the dependency graph:

Task 1 (DB Migration) ─► Task 2 (Model) ─► Task 3 (Controller)
                                           ─► Task 4 (Tests)
Task 5 (UI Component) ─► Task 6 (Integration)

Classify tasks:

Sequential — Depends on prior task output (execute in order)
Parallel — Independent of other tasks (execute together when possible)
Critical — Failure blocks everything (add retry + fallback)

Step 1: Scaffold & Setup

Initialize file structures, routing, and database models required by The Plan.

Checklist:

Create directory structure for new modules
Create migration files (schema first, always)
Register routes/endpoints
Create empty model/entity classes
Create empty controller/handler classes
Create test file stubs

Log format:

[PHASE 1/4] SCAFFOLD
  [STEP 1/6] Creating directory structure... DONE
  [STEP 2/6] Creating migration files... DONE
  ...

Step 2: Test-Driven Implementation Loop

For each task in The Plan, execute this cycle:

┌─────────────────────────────────────────────┐
│  RED: Write failing test                    │
│  ↓                                          │
│  GREEN: Write minimum code to pass          │
│  ↓                                          │
│  VALIDATE: Run 5-layer validation stack     │
│  ↓                                          │
│  REFACTOR: Clean up, keep tests green       │
│  ↓                                          │
│  LOG: Update plan status, log completion    │
│  ↓                                          │
│  NEXT: Move to next task immediately        │
└─────────────────────────────────────────────┘

Per-task execution:

[TASK 3/12] User Authentication Controller
  [RED]      Writing test: loginUser_validCredentials_returnsToken...
  [RED]      Writing test: loginUser_invalidPassword_returns401...
  [GREEN]    Implementing AuthController@login...
  [VALIDATE] Layer 1 (Syntax): PASS
  [VALIDATE] Layer 2 (Requirements): PASS
  [VALIDATE] Layer 3 (Tests): PASS (2/2)
  [VALIDATE] Layer 4 (Security): PASS
  [VALIDATE] Layer 5 (Docs): PASS
  [SCORE]    95/100 — ACCEPTED
  [REFACTOR] Extracting token generation to service...
  [STATUS]   Task 3: COMPLETED ✅
  [NEXT]     Moving to Task 4...

Step 3: 5-Layer Validation Stack

Every piece of generated code MUST pass all 5 layers before proceeding. Reference: ai-error-handling skill.

Layer	Check	Tool	Pass Criteria
1. Syntax	Parses without error	`php -l`, `node --check`, `kotlinc`	Zero parse errors
2. Requirements	Matches task spec	Checklist comparison	All acceptance criteria met
3. Tests	All tests pass	Test runner	Green on happy + edge + error
4. Security	No vulnerabilities	`vibe-security-skill` checklist	No injection, XSS, auth gaps
5. Documentation	Code is explainable	Self-review	Functions documented, logic clear

Quality scoring:

Component	Points
Syntax + style	20
Requirements + edge cases	30
Test coverage	20
Security	20
Documentation	10
Acceptance threshold	>= 80/100

Validation loop:

Generate → Validate → PASS? → Accept & continue
                    → FAIL? → Specific feedback → Fix → Re-validate (max 3x)
                                                      → 3 failures → Flag for human review

Step 4: Verify & Self-Correct

After each task:

Run tests — Execute the test suite for the module
Check integration — Verify new code doesn't break existing tests
Self-correct — If tests fail, diagnose autonomously and fix
Provide commands — If tests can't be run inline, output exact terminal commands:

# Run unit tests for auth module
php artisan test --filter=AuthControllerTest
# or
./gradlew :app:testDebugUnitTest --tests="*.AuthViewModelTest"
# or
npm test -- --testPathPattern="auth"

Step 5: Iterate Without Stopping

After completing a task:

Update the plan file — Mark task status as completed
Check dependency graph — Unlock any blocked tasks
Move immediately to the next task
Do NOT output summaries between tasks (save for the end)

Output Token Limit Recovery

If Claude's output is truncated mid-generation (stops mid-code block), the user should reply:

"Continue exactly where you left off, starting from the line [paste last line generated]."

This prevents restarting the file. The executor must:

Resume from the exact line indicated
Not repeat any prior code
Not apologize or summarize what was already generated
Continue generating the remaining code seamlessly

Cross-Skill Integration

This executor depends on and enforces patterns from other skills:

Phase	Upstream Skill	What It Provides
Plan source	`feature-planning`	Task breakdown, specs, acceptance criteria
Design baseline	`sdlc-design`	Architecture, DB design, API contracts
Test standards	`sdlc-testing`, `android-tdd`	Test pyramid, TDD cycle, coverage targets
Orchestration	`orchestration-best-practices`	10 Commandments for multi-step execution
Error prevention	`ai-error-prevention`	7 strategies to prevent bad code generation
Validation	`ai-error-handling`	5-layer validation stack, quality scoring
Security	`vibe-security-skill`	Security checklist for every endpoint
DB standards	`mysql-best-practices`	Schema design, indexing, multi-tenant patterns
API patterns	`api-error-handling`, `api-pagination`	Error responses, pagination
Auth	`dual-auth-rbac`	Session + JWT, RBAC enforcement
UI (Web)	`webapp-gui-design`	Template patterns, SweetAlert2, DataTables
UI (Mobile)	`jetpack-compose-ui`	Material 3, state hoisting, animations
Multi-tenant	`multi-tenant-saas-architecture`	Tenant isolation, scoping
Post-execution	`implementation-status-auditor`	Verify completeness after all tasks done

Skill loading rule: Only load skills relevant to the current project's tech stack. A PHP web app doesn't need android-tdd.

The 10 Commandments (Mandatory)

Every task execution MUST follow these. Reference: orchestration-best-practices.

Define steps explicitly — Each task has numbered, clear steps
Identify dependencies — Know what must complete first
Validate inputs — Check preconditions before executing
Handle errors — Try-catch with recovery, never silent failures
Validate outputs — Verify results match expectations
Log progress — Start/complete of every step logged
Document thoroughly — Functions have docblocks explaining behavior
Test thoroughly — Happy path + edge cases + error cases
Have fallbacks — Critical operations have Plan B
Parallelize — Independent tasks run concurrently

Execution Phases Template

[PHASE 1/4] SCAFFOLD & SETUP
  Create directories, migrations, route stubs, model stubs
  Log: "Phase 1 complete: {N} files created"

[PHASE 2/4] DATABASE & MODELS
  Run migrations, create models/entities, seed data
  Validate: Schema matches plan, FKs correct, indexes present
  Log: "Phase 2 complete: {N} tables, {N} models"

[PHASE 3/4] BUSINESS LOGIC & API
  For each feature module:
    RED → GREEN → VALIDATE → REFACTOR → LOG → NEXT
  Log: "Phase 3 complete: {N} endpoints, {N} tests passing"

[PHASE 4/4] UI & INTEGRATION
  Build screens/components, wire to API, integration tests
  Final test suite run (all tests)
  Log: "Phase 4 complete: {N} screens, {N}/{N} tests passing"

[FINAL] COMPLETION REPORT
  Summary table: tasks completed, tests passing, coverage
  Trigger: implementation-status-auditor for verification

End-of-Phase Git Workflow

After completing each phase (all tasks green, plan status updated):

Stage all changed/new files — git add the specific files created or modified in the phase
Commit — Use a descriptive commit message summarizing the phase work
Push — git push to the remote repository

[PHASE COMPLETE] Phase 1.1 — Restaurant POS Tests
  [GIT] Staging 8 new test files...
  [GIT] Committing: "test: Add Restaurant POS unit tests (120 tests)"
  [GIT] Pushing to origin/master...
  [GIT] Push complete ✅

Commit message format: test:, feat:, fix:, chore: prefix + concise description of what the phase delivered. Include Co-Authored-By trailer.

This is MANDATORY — never finish a phase without committing and pushing.

Anti-Patterns

Don't	Do Instead
Output `// TODO: implement`	Write complete implementation
Stop to ask about naming	Use project conventions or best practice
Skip tests for "simple" code	Every feature gets tests
Merge multiple plan tasks into one	Execute each task individually
Ignore failing tests and move on	Fix until green, then proceed
Generate code without validation	Run 5-layer stack on everything
Forget to update plan status	Mark completed after each task
Write one massive commit	Commit per logical unit (phase or module)
Silently swallow errors	Log error, attempt fix, escalate if stuck
Skip security checks on endpoints	Apply `vibe-security-skill` to every route

Plan Status Format

Update the plan file in-place as tasks complete:

### Task 3: User Authentication Controller
**Status:** ✅ COMPLETED
**Tests:** 5/5 passing
**Quality Score:** 92/100
**Files Modified:**
- `app/Http/Controllers/AuthController.php` (created)
- `tests/Feature/AuthControllerTest.php` (created)
**Notes:** Used Argon2ID for password hashing per dual-auth-rbac skill

Completion Criteria

The plan is NOT complete until:

Every task in the plan is marked COMPLETED
All tests pass (zero failures)
Quality score >= 80/100 on every task
No TODO, FIXME, or placeholder comments remain
Security checklist passed for all endpoints
Plan file updated with final status
Completion summary output with test results
