What Knowledge Layer does

Knowledge Layer provides a high-level deployment wrapper over RepoBrain core with graph-first knowledge injection and all-file support. Use it to build and query a repository knowledge graph via refresh_filesystem and ask_filesystem.

Knowledge Layer is cataloged under AI Engineering on DirSkills. Knowledge Layer comes from a repository tagged agents-sdk, ai-agent, claude-code, code-intelligence and code-search.

Documentation

README

Excerpt

refresh_filesystem(workspace=".", quick=False)
ask_filesystem(question, workspace=".")

Outputs

Refresh writes graph-first artifacts under .repobrain/:
- knowledge_graph.json
- knowledge_graph.md
- knowledge_graph.mmd
- document_index.md
- data_overview.md
- media_manifest.md
- plus existing conventions.md and structure.md
Ask returns a grounded answer with source paths.

Boundaries

Skill is a wrapper layer only; no standalone runtime.
Core Hub/Agent/Pipeline architecture remains the source of truth.

This is the opening of the README. Read the full README on GitHub.
