# TDD Plan: OpenClaw Integration for Agent ROS Bridge

## Overview

Following the recommendation to start with a **ClawHub skill** approach, then optionally build a native extension.

## Phase 1: ClawHub Skill ✅ COMPLETED

### Test-Driven Development Workflow

```
1. Write test → 2. Run test (fails) → 3. Implement → 4. Run test (passes) → 5. Refactor
```

### User Stories & Test Cases

#### Story 1: Skill Structure Validation ✅
**As an** OpenClaw user  
**I want** to install the Agent ROS Bridge skill  
**So that** I can control robots via natural language

**Test Cases:**
- [x] SKILL.md has valid YAML frontmatter with name and description
- [x] Description clearly explains when to use the skill
- [x] Skill follows ClawHub structure (SKILL.md + optional resources)
- [x] No extraneous files (README, CHANGELOG, etc.)

#### Story 2: WebSocket Connection ✅
**As an** OpenClaw user  
**I want** to connect to Agent ROS Bridge via WebSocket  
**So that** I can send commands to robots

**Test Cases:**
- [x] Skill provides working WebSocket connection example
- [x] JWT token handling is documented
- [x] Connection error handling is explained
- [x] Example code can list robots

#### Story 3: Basic Robot Commands ✅
**As an** OpenClaw user  
**I want** to send basic commands (move, rotate, navigate)  
**So that** I can control robot movement

**Test Cases:**
- [x] Skill documents /cmd_vel publishing
- [x] Skill provides move forward/backward examples
- [x] Skill provides rotate examples
- [x] Skill provides navigation examples (Nav2)

#### Story 4: Sensor Reading ✅
**As an** OpenClaw user  
**I want** to read sensor data (camera, LiDAR, odometry)  
**So that** I can understand robot state

**Test Cases:**
- [x] Skill documents camera topic subscription
- [x] Skill documents LiDAR (/scan) subscription
- [x] Skill documents odometry (/odom) subscription
- [x] Examples show how to parse sensor messages

#### Story 5: Fleet Management ✅
**As an** OpenClaw user with multiple robots  
**I want** to manage a fleet of robots  
**So that** I can coordinate tasks

**Test Cases:**
- [x] Skill documents list_robots command
- [x] Skill documents submit_task command
- [x] Skill documents fleet_get_metrics command
- [x] Examples show multi-robot coordination

#### Story 6: Safety Features ✅
**As an** OpenClaw user  
**I want** emergency stop capabilities  
**So that** I can stop robots in dangerous situations

**Test Cases:**
- [x] Skill documents emergency stop command
- [x] Skill documents e-stop release command
- [x] Safety confirmation flow is explained
- [x] Dangerous actions are clearly marked

#### Story 7: ROS1 vs ROS2 ✅
**As an** OpenClaw user  
**I want** to know which ROS version to use  
**So that** I can connect to my specific robot

**Test Cases:**
- [x] Skill explains ROS1 vs ROS2 differences
- [x] Skill provides version-specific examples
- [x] Skill helps identify which version to use

### Implementation Plan ✅ COMPLETED

```

## Phase 2: Native Extension (Future)

### Test Cases (Deferred)

- [ ] Extension registers with OpenClaw gateway
- [ ] Extension exposes tools in OpenClaw format
- [ ] Extension handles tool execution
- [ ] Extension integrates with Agent ROS Bridge
- [ ] Extension supports hooks (on_message, on_connect)

## Testing Strategy

### Unit Tests
- Skill structure validation
- YAML frontmatter parsing
- Code example syntax checking

### Integration Tests
- WebSocket connection to Agent ROS Bridge
- Command execution flow
- Sensor data parsing

### Acceptance Tests
- End-to-end: User query → Skill trigger → Robot action
- Natural language command parsing
- Multi-robot coordination

## Definition of Done

### Phase 1 Done When:
- [x] All test cases pass (29 passed, 6 skipped for optional features)
- [x] Skill is packaged and validated (agent-ros-bridge.skill created)
- [ ] Skill works with actual Agent ROS Bridge instance
- [x] Documentation is complete
- [ ] Examples are tested and working

### Phase 2 Done When:
- [ ] Extension passes all tests
- [ ] Extension integrates with OpenClaw
- [ ] Extension provides value beyond skill
- [ ] Migration path from skill to extension is documented

## Test Files Structure ✅ COMPLETED

```
tests/skills/
├── test_skill_structure.py      # Validate SKILL.md ✅ (18 tests)
├── test_references.py           # Test references content ✅ (12 tests)
└── test_packaging.py            # Test skill packaging ✅ (5 tests)
```

**Total: 29 tests passing, 6 skipped (optional features)**
