# For AI agents `ef` ships artifacts for coding agents alongside its code. This page lists them, says where each lives in the repository, and points at the machine-readable copies of this documentation. ## Skills Skills are folders holding a `SKILL.md` (the [Agent Skills](https://agentskills.io) format): a description that tells an agent when to use it and a body with the procedure. Install one into your agent with `gh skill` (any host: `--agent claude-code`, `copilot`, `cursor`, `codex`, `gemini`), or use the copy bundled in the wheel. ### `ef-architecture` Developer skill: the target architecture of the ef (Embedding Flow) package. Load at the start of any non-trivial task in the ef repository — refactoring, adding the Embedder/Segmenter facades, the Corpus abstraction, the ArtifactGraph indexing core, or the “ready search” surface. Covers the five-layer model, the core contracts, the light/heavy progressive-disclosure split, and the hard boundaries. Trigger on “work on ef”, “refactor ef”, “implement the embedder/segmenter/corpus/artifact graph”, “ef search”. ```bash gh skill install thorwhalen/ef ef-architecture --agent claude-code ``` Source: [`skills/ef-architecture`](https://github.com/thorwhalen/ef/tree/HEAD/skills/ef-architecture). ## Instruction files Files agents read before working in this repository. - [`.claude/CLAUDE.md`](https://github.com/thorwhalen/ef/tree/HEAD/.claude/CLAUDE.md): read by Claude Code ## Machine-readable documentation This site publishes the same documentation in forms that fit an agent’s context window: - [`llms.txt`](https://thorwhalen.github.io/ef/llms.txt): an index of every page with a one-line description ([llms.txt](https://llmstxt.org) format) - [`ef.md`](https://thorwhalen.github.io/ef/ef.md): the whole documentation as one Markdown file - `.html.md`: a rendered Markdown twin of every page, advertised from each page’s `` with `` - [`objects.inv`](https://thorwhalen.github.io/ef/objects.inv): the Sphinx inventory: a symbol-to-URL index (`sphobjinv convert plain objects.inv -`)
