MCP tools
Knowledge tools enforce category boundaries, Markdown-only reads, file-size limits, and path-traversal protection. Search before opening deep reference files — a no-match response is a valid result.
Retrieval scope
The search index is defined by knowledge-base/retrieval-scope.yaml. It contains only explicitly approved distributable files and excludes local raw research and legacy archives. SKILL.md remains authoritative when supporting documents conflict.
