# Browser Integration Prerequisites Test Summary
## Overview
The `test-browser-prerequisites.js` test suite verifies all prerequisites needed before browser integration. It tests models, tools, custom agents, custom skills, and response validation using isolated Claude instances.
## Test Categories
### 1. Model Tests (3 tests)
#### Test 1: Model Responses
- Tests all models (sonnet, opus, haiku) respond correctly
- Verifies response quality and completeness
- Ensures each model works with isolated instances
#### Test 2: Model Cost Differences
- Compares costs across different models
- Verifies cost tracking works
- Helps choose appropriate model for use case
#### Test 3: Model Tool Execution
- Tests that tools work with all models
- Verifies model-agnostic tool support
- Ensures consistent behavior across models
### 2. Tool Tests (3 tests)
#### Test 4: Tool Discovery
- Verifies both tools (`log_thought`, `update_ui`) are discoverable
- Tests tool name resolution
- Confirms MCP server connection
#### Test 5: Tool Execution Patterns
- Single tool calls
- Multiple tools in sequence
- Tools with parameters
- Verifies all execution patterns work
#### Test 6: Tool Error Handling
- Invalid tool names
- Missing required parameters
- Error message validation
- Graceful error handling
### 3. Custom Agent Tests (2 tests)
#### Test 7: Custom Agent Creation
- Tests `--agents` flag
- Creates calculator agent
- Verifies agent behavior
- Tests agent instructions
#### Test 8: Agent With Tools
- Tests agent that uses tools
- UI builder agent example
- Verifies agent + tool integration
- Tests agent instructions with tool calls
### 4. Custom Skill Tests (2 tests)
#### Test 9: Custom Skill Loading
- Creates test skill files
- Validates skill file format (SKILL.md)
- Tests frontmatter structure
- Verifies skill metadata
#### Test 10: Skill Execution
- Tests skill-like behavior
- Creates UI helper skill
- Verifies skill instructions
- Tests skill + tool integration
### 5. Response Validation Tests (3 tests)
#### Test 11: Response Format Validation
- Tests JSON response format
- Validates response structure
- Ensures parseable output
- Tests format compliance
#### Test 12: Response Completeness
- Verifies responses aren't truncated
- Tests complete answer delivery
- Validates response length
- Ensures all requested data included
#### Test 13: Response Consistency
- Tests same prompt multiple times
- Verifies consistent (or valid) responses
- Validates answer correctness
- Tests response reliability
### 6. Browser Integration Prerequisites (3 tests)
#### Test 14: WebSocket Message Format
- Validates message format specification
- Tests LOG message format
- Tests UPDATE_DOM message format
- Ensures browser compatibility
#### Test 15: Tool Response Time
- Tests response time (< 30 seconds)
- Validates acceptable latency
- Ensures good UX
- Tests performance
#### Test 16: Concurrent Tool Calls
- Tests multiple simultaneous calls
- Verifies no interference
- Tests concurrency handling
- Validates parallel execution

## What Gets Tested
### Models
- ✅ Sonnet (default, cost-effective)
- ✅ Opus (high quality, more expensive)
- ✅ Haiku (fast, cheapest)
- ✅ All models respond correctly
- ✅ Tool execution works with all models
### Tools
- ✅ Tool discovery
- ✅ Tool execution patterns
- ✅ Error handling
- ✅ Parameter validation
- ✅ Multiple tool calls
### Custom Agents
- ✅ Agent creation via `--agents` flag
- ✅ Agent instructions
- ✅ Agent + tool integration
- ✅ Multiple agents
### Custom Skills
- ✅ Skill file creation
- ✅ Skill format validation
- ✅ Skill instructions
- ✅ Skill + tool integration
### Response Validation
- ✅ Format validation
- ✅ Completeness
- ✅ Consistency
- ✅ Performance
## Browser Integration Readiness
After all tests pass, you have verified:
1. ✅ **Models work correctly** - All models respond and execute tools
2. ✅ **Tools are functional** - Discovery, execution, error handling all work
3. ✅ **Custom agents work** - Can create and use custom agents
4. ✅ **Custom skills work** - Can create and reference skills
5. ✅ **Responses are valid** - Format, completeness, consistency verified
6. ✅ **Performance is acceptable** - Response times within limits
7. ✅ **Concurrency works** - Multiple calls don't interfere
8. ✅ **Message formats are correct** - WebSocket messages properly formatted
## Next Steps After Tests Pass
1. ✅ All prerequisites verified
2. ✅ Ready for browser integration
3. ✅ Can proceed with UI building
4. ✅ Tool execution confirmed working
5. ✅ Models validated
6. ✅ Agents and skills tested
## Integration Points
These tests verify the foundation for:
- Browser UI updates via `update_ui` tool
- Logging via `log_thought` tool
- Model selection for different use cases
- Custom agent workflows
- Skill-based workflows
- Real-time WebSocket communication
All primitives are tested and ready for browser integration!
