+# Mnemon Agent Guidelines
+
+## Development
+
+- Build with `go build -o mnemon .`.
+- Run the E2E suite with `bash scripts/e2e_test.sh` or `make test`.
+- Validate harness module manifests with `make harness-validate` when changing
+  harness module assets.
+- Treat `.claude/`, `.codex/`, `.openclaw/`, and similar host directories as
+  local projection surfaces, not canonical project state.
+
+## Commit Discipline
+
+- Prefer small, logical commits. Split unrelated work instead of committing a
+  broad mixed diff.
+- Keep tightly coupled changes together when splitting would leave either commit
+  misleading or incomplete.
+- Use the project style already present in history: a concise Conventional
+  Commit title plus one or two focused body paragraphs, with bullets only when
+  they improve scanning.
+- Choose the commit type by the primary project effect:
+  - `feat` for new developer-facing or harness capabilities.
+  - `fix` for correctness repairs.
+  - `test` for tests, eval scenarios, or fixtures that do not add a new
+    reusable capability.
+  - `docs` for documentation-only changes.
+  - `refactor` for structure changes without intended behavior changes.
+  - `chore` for repository hygiene and maintenance.
+- Mention validation in the body when tests, evals, or manual checks are part of
+  the work.
+- Do not include agent attribution or co-author lines unless explicitly asked.
