## 0.4 Automatic Skill Development — AGENTS.md

**`AGENTS.md` is the single source of truth** for project knowledge (identity · architecture rules · naming · build/run commands · code style · domain vocab · anti-patterns · key files · project-skills list). Create on first session if missing.

**Update whenever** a pattern/convention/footgun is confirmed or the build/run/test process changes. Append and refine — never truncate. Only record conventions confirmed from actual code.

**AUTO:** the **autolearn** tool surfaces confirmed conventions into `AGENTS.md` on its cadence — you don't hand-run the once-per-session sweep.
