## Capabilities

- Parse plugin interfaces from README.md files
- Parse agent definitions from CLAUDE.md files
- Validate cross-plugin compatibility
- Identify interface mismatches and conflicts
- Generate detailed validation reports

## Available Tools

### Parsing
- `parse_plugin_interface` - Extract interface from plugin README.md
- `parse_claude_md_agents` - Extract agents from CLAUDE.md

### Validation
- `validate_compatibility` - Check two plugins for conflicts
- `validate_agent_refs` - Verify agent tool references exist
- `validate_data_flow` - Check data flow through agent sequences

### Reporting
- `generate_compatibility_report` - Full marketplace report
- `list_issues` - Filter issues by severity/type

## Workflow

1. **Discover plugins**:
   - Locate marketplace plugins directory
   - Identify plugins by `.claude-plugin/` marker
   - Build list of all plugins to validate

2. **Parse all interfaces**:
   - For each plugin, use `parse_plugin_interface`
   - Extract commands, agents, tools from README.md
   - Track tool categories and features

3. **Run pairwise compatibility checks**:
   - For each pair of plugins, use `validate_compatibility`
   - Check for command name conflicts (ERROR)
   - Check for tool name overlaps (WARNING)
   - Identify interface mismatches

4. **Validate CLAUDE.md agents** (if present):
   - Use `parse_claude_md_agents` on project CLAUDE.md
   - For each agent, use `validate_agent_refs`
   - Use `validate_data_flow` to check sequences

5. **Generate comprehensive report**:
   - Use `generate_compatibility_report`
   - Format: markdown for human review, JSON for programmatic use
   - Include summary statistics and detailed findings

## Report Structure

### Summary
- Total plugins scanned
- Total commands, agents, tools found
- Issue counts by severity (error/warning/info)

### Compatibility Matrix
- Plugin pairs with conflicts
- Shared tools between plugins
- Unique tools per plugin

### Issues List
- ERROR: Command name conflicts (must fix)
- WARNING: Tool name overlaps (review needed)
- INFO: Undocumented references (improve docs)

### Recommendations
- Actionable suggestions per issue
- Priority order for fixes
