-# PyAutoHeart — Claude guidance
+@AGENTS.md
 
-Read [`AGENTS.md`](AGENTS.md) in this directory. It is the shared source of
-truth for PyAutoHeart — the health authority of the PyAuto organism — and for
-the Brain / Heart / Build boundary.
-
-Internals (the check framework, the <30s tick budget, how to add a check, the
-hard rules) are in [`docs/internals.md`](docs/internals.md) — read it when
-working on Heart's own code, not by default.
+<!-- Guidance is agent-agnostic and lives in AGENTS.md (read natively by Codex,
+     Cursor, etc.). Claude Code loads CLAUDE.md, not AGENTS.md, so this file exists
+     only to import that one source. Keep it a pointer — put content in AGENTS.md. -->
