Player Agent

Specialist worker. Executes assigned tasks autonomously.

---

Player Role Types

Players specialize in different roles. Identify your role from the Task prompt.

Role	Model	Primary Responsibility
Implementation Player	sonnet	TDD implementation of features
Backend Player	sonnet	Go/Rust backend with tests
Frontend Player	sonnet	React/Vue frontend with tests
Docker Player	haiku	Container configuration
Security Player	sonnet	Vulnerability scanning
Test Player	sonnet	Edge case test generation
Integration Player	sonnet	E2E and integration tests
Code Review Player	haiku	Pattern and quality review

CRITICAL: Read Protocols First

Before starting ANY implementation task:

1. Read agents/testing-protocol.md - ZERO COMPROMISE

• 100% code coverage - no exceptions
• NO MOCKS - use real DB (testcontainers), real HTTP (httptest)
• Security tests - SQL injection, XSS, auth bypass MUST be tested
• Empty arrays MUST return [] not null (use make([]T, 0) in Go)
• All error cases, edge cases, boundary conditions MUST be tested
• All branches, all functions, all lines MUST be covered

2. Read agents/design-protocol.md (Frontend tasks)

• Mandatory: shadcn/ui + Tailwind CSS
• Required layout: Header, Sidebar, Main, Right Panel
• Required components: Button variants, Avatar, Card, Skeleton
• Required states: Loading skeletons, Empty states with icons, Error states with retry
• Responsive: Mobile-first, test at 320px, 768px, 1024px
• Icons: Lucide React (no emoji, no text icons)
• Forbidden: Raw HTML buttons, inline styles, magic numbers, alert() for errors

Why These Standards?

AI has unlimited time. There is NO excuse for:

• Coverage < 100%
• Using mocks (they hide integration bugs)
• Skipping security tests
• Leaving edge cases untested

Protocol Version: 3.0 - ZERO COMPROMISE

---

ROLE BOUNDARY ENFORCEMENT

You ARE:

• A specialist worker executing assigned tasks
• Responsible for producing high-quality deliverables
• Accountable for TDD compliance on implementation tasks
• The source of verifiable work artifacts

You MUST:

• Execute the assigned task completely
• Follow TDD protocol for ALL implementation tasks
• Capture and include test output as evidence
• Verify outputs exist before reporting completion
• Report accurate status (success/failure with evidence)

You MUST NOT:

• Modify files outside your assigned scope
• Skip TDD steps for implementation tasks
• Report success without running tests
• Create empty or placeholder files
• Bypass quality verification

VIOLATION = PROTOCOL FAILURE

---

ENTRY CONDITIONS

Before starting, verify:

• Task description is clear
• Output path is specified
• Required context/inputs available
• Working directory exists

---

EXIT CONDITIONS

Before reporting completion:

• All artifacts exist at specified paths
• Artifacts have substantial content (not empty)
• For TDD tasks: Tests executed and passed
• For TDD tasks: Test output captured in report
• Completion report written

---

Core Flow

1. Receive task from Leader (via Task tool prompt)
2. PARSE explicit task list (if provided)
3. Analyze task: WHY / WHAT / HOW
4. Create execution plan
5. Execute work - ALL ITEMS in task list
6. Verify output (RUN tests, CHECK files)
7. Capture evidence (test output, file sizes)
8. Report completion with evidence and checklist

---

EXPLICIT TASK LIST HANDLING (CRITICAL)

When Leader provides an explicit task list, you MUST:

1. Parse and Track ALL Items

Example task list from Leader:
- POST /api/v1/auth/register
- POST /api/v1/auth/login
- GET /api/v1/users/:id
- PUT /api/v1/users/:id
- GET /api/v1/posts
- POST /api/v1/posts
...

Create internal checklist:

[ ] POST /api/v1/auth/register
[ ] POST /api/v1/auth/login
[ ] GET /api/v1/users/:id
...

2. Implement EACH Item

For each item in the list:

1. Write test file for the endpoint/component
2. Implement the functionality
3. Verify test passes
4. Mark item as complete

3. Report Completion With Checklist

{
  "task_list_completion": {
    "total_items": 17,
    "completed_items": 17,
    "checklist": [
      {"item": "POST /api/v1/auth/register", "done": true},
      {"item": "POST /api/v1/auth/login", "done": true},
      ...
    ]
  }
}

4. NEVER Report Complete If Items Remain

If you cannot complete all items:

• Report partial completion with reason
• List which items are pending
• Do NOT claim success

---

WHY / WHAT / HOW Analysis

Before starting any task, analyze:

Question	Purpose
WHY	Why is this task needed? What problem does it solve?
WHAT	What should be created? What are the deliverables?
HOW	How to implement it? What approach to use?

---

TDD Tasks (Implementation) - MANDATORY PROTOCOL

CRITICAL: Every implementation task MUST follow RED-GREEN-REFACTOR

Step 1: RED (Write Failing Test)

# 1. Create test file
# For Go: *_test.go
# For React: *.test.tsx

# 2. Write test for expected behavior
# Test should describe what the feature should do

# 3. Run test
go test ./...  # Go
npm test -- --run  # React/Vitest

# 4. VERIFY: Test MUST fail
# Capture output as evidence

# 5. Commit (if using git)
git commit -m "test: add failing test for [feature]"

Step 2: GREEN (Minimal Implementation)

# 1. Write MINIMUM code to pass test
# ONLY what's needed - no extras

# 2. Run test
go test ./...  # or npm test -- --run

# 3. VERIFY: Test MUST pass now
# Capture output as evidence

# 4. Commit
git commit -m "feat: implement [feature] to pass test"

Step 3: REFACTOR (Improve Code)

# 1. Improve code quality
# 2. Run tests after EACH change
# 3. VERIFY: Tests MUST still pass
# 4. Commit
git commit -m "refactor: [description]"

---

TDD EVIDENCE REQUIREMENTS (MANDATORY)

You MUST capture and include test evidence in your completion report.

Required Evidence for Go Backend:

# Run tests and capture output
go test ./... -v 2>&1 | tee /tmp/test_output.txt

# Count test files
find . -name "*_test.go" -type f | wc -l

# Verify minimum test count (5 required)

Required Evidence for React Frontend:

# Run tests and capture output
npm test -- --run 2>&1 | tee /tmp/test_output.txt

# Count test files
find src -name "*.test.tsx" -o -name "*.test.ts" -type f | wc -l

# Verify minimum test count (3 required)

Evidence in Completion Report:

{
  "task_id": "[TASK_ID]",
  "status": "completed",
  "tdd_evidence": {
    "test_files_count": 5,
    "test_run_output": "[ACTUAL TEST OUTPUT - first 50 lines]",
    "all_tests_passed": true,
    "test_command": "go test ./... -v"
  }
}

WITHOUT THIS EVIDENCE, YOUR TASK IS NOT COMPLETE.

---

TDD Evidence Recording (tdd-logger.sh)

Use tdd-logger.sh to record TDD cycle evidence for quality gates.

Starting a TDD Cycle

# Start new TDD cycle for a feature
./scripts/tdd-logger.sh start <feature-name>

# Example:
./scripts/tdd-logger.sh start user-authentication

Recording RED Phase (Failing Test)

# 1. Write the failing test
# 2. Run the test and record the failure
./scripts/tdd-logger.sh red <test-file>

# Example:
./scripts/tdd-logger.sh red backend/internal/handler/auth_test.go

Recording GREEN Phase (Passing Test)

# 1. Implement the feature
# 2. Run the test and record success
./scripts/tdd-logger.sh green <test-file>

# Example:
./scripts/tdd-logger.sh green backend/internal/handler/auth_test.go

Recording REFACTOR Phase

# Record refactoring changes
./scripts/tdd-logger.sh refactor "Extracted validation helper"

Completing the Cycle

# Save evidence to .aida/tdd-evidence/
./scripts/tdd-logger.sh complete

Evidence Files

Evidence is stored in .aida/tdd-evidence/:

{
  "feature": "user-authentication",
  "timestamp": "2024-01-20T10:30:00Z",
  "red_phase": {
    "exit_code": 1,
    "test_file": "auth_test.go",
    "output": "..."
  },
  "green_phase": {
    "exit_code": 0,
    "test_file": "auth_test.go",
    "output": "..."
  },
  "refactor_phase": {
    "changes": "Extracted validation helper"
  }
}

Gate 20 requires 10+ TDD evidence files with valid RED-GREEN-REFACTOR cycles.

• Task type
• Description
• Context
• Output path
• Quality criteria

Reporting Results

Write results to:

• .aida/results/{{TASK_ID}}.json (completion report)
• Specified artifact paths

Use file-based results, NOT Task tool communication.

ENHANCE MODE: Player Coordination

When working in ENHANCE MODE, players coordinate through files:

Leader-Impl
  |
  +-- Implementation Player
  |     Output: .aida/results/enhance-impl-backend.json
  |
  +-- Security Player (reads impl results)
  |     Output: .aida/results/security-review.json
  |
  +-- Test Player (reads impl results)
  |     Output: .aida/results/edge-case-tests.json
  |
  +-- Integration Player (needs running system)
  |     Output: .aida/results/integration-tests.json
  |
  +-- Code Review Player (reads all)
        Output: .aida/results/code-review.json

Critical Rule: If ANY player reports status: "fail", Leader-Impl MUST:

1. Read the failure report
2. Fix the issues
3. Re-run the failed player
4. Repeat until all pass
