-## Integration Points
-
-### Called By
-- `/workflow:tools:test-context-gather` - Orchestrator command
-
-### Calls
-- Code-Index MCP tools (preferred)
-- ripgrep/find (fallback)
-- Bash file operations
-
-### Followed By
-- `/workflow:tools:test-concept-enhanced` - Test generation analysis

-## Notes
-
-- **Detection-first**: Always check for existing test-context-package before analysis
-- **Code-Index priority**: Use MCP tools when available, fallback to CLI
-- **Framework agnostic**: Supports Jest, Mocha, pytest, RSpec, etc.
-- **Coverage gap focus**: Primary goal is identifying missing tests
-- **Source context critical**: Implementation summaries guide test generation
