Read dependency usage rules — the LLM-oriented usage-rules.md docs that
Elixir libraries ship in their Hex package (the usage_rules convention).
These live locally in the project's deps:
deps/<pkg>/usage-rules.md→ addressed as<pkg>deps/<pkg>/usage-rules/<topic>.md→ addressed as<pkg>:<topic>
Prefer this over web_fetch of hexdocs: it's local, fast, version-accurate
for exactly the deps in this project, and can't time out on a slow network.
- No
packagearg → lists every available rule set in the project's deps. package: "ash"→ returnsdeps/ash/usage-rules.md.package: "phoenix:html"→ returnsdeps/phoenix/usage-rules/html.md.
