+## Agent Contribution Guide
+
+Whenever an automated agent lands code in this repository, it must also:
+
+- Bump the crate version in `Cargo.toml` before shipping.
+- Choose the bump size using semantic versioning rules:
+  - Increment the **major** version (`x.0.0`) for breaking changes.
+  - Increment the **minor** version when adding backward-compatible functionality.
+  - Increment the **patch** version for bug fixes and other backward-compatible maintenance work.
+
+If you are unsure which category applies, err on the side of a **minor** bump and leave a note in your PR with the reasoning.
