+### Pre-commit hooks (recommended)
+
+This repository includes [pre-commit](https://pre-commit.com/) configuration at [`.pre-commit-config.yaml`](.pre-commit-config.yaml): YAML checks and a **commit-msg** hook that enforces the [Conventional Commits](https://www.conventionalcommits.org/en/v1.0.0/) rules above (including a required **scope**).
+
+**Setup (once per clone):**
+
+```bash
+pip install pre-commit   # or: brew install pre-commit
+pre-commit install --install-hooks
+```
+
+The install registers both the default `pre-commit` stage and `commit-msg` hooks. To validate the latest commit message manually:
+
+```bash
+git log -1 --pretty=%B > /tmp/msg.txt
+pre-commit run conventional-pre-commit --hook-stage commit-msg --commit-msg-filename /tmp/msg.txt
+```
+
 ## Boundaries
 
 - ✅ **Always do:** Edit XML in `system-prompts-generator/src/main/resources/` to change rules, run `./mvnw clean verify` before promoting changes. When edit XML, follow PML Schema: [https://jabrena.github.io/pml/schemas/0.7.0/pml.xsd](https://jabrena.github.io/pml/schemas/0.7.0/pml.xsd).

+- **Git:** use [Conventional Commits](https://www.conventionalcommits.org/) in the form `type(scope): description`, with types such as `feat`, `fix`, `docs`, `style`, `refactor`, `test`, and `chore` (see AGENTS.md).
+- **Pre-commit (recommended):** this repo includes [pre-commit](https://pre-commit.com/) in [`.pre-commit-config.yaml`](.pre-commit-config.yaml) (YAML checks and a commit-msg hook aligned with the rules above). Install once per clone: `pip install pre-commit` or `brew install pre-commit`, then `pre-commit install --install-hooks`. Details and manual checks are in AGENTS.md under **Pre-commit hooks**.
+
 ## Generator
 
 The entire set of cursor rules is autogenerated by XML files in the project `system-prompts-generator`.
