+# Git Commit Skill
+
+Before making any commit, ensure the following steps are completed:
+
+## 1. Install dependencies
+
+Dependencies must be installed so that husky and all dev tools are available:
+
+```bash
+npm install --legacy-peer-deps
+```
+
+## 2. Set up husky git hooks
+
+The `prepare` script initialises husky (sets `core.hooksPath` to `.husky/_`).
+Run it explicitly if hooks are not yet installed:
+
+```bash
+npm run prepare
+```
+
+You can verify that the hook chain is in place:
+
+```bash
+git config core.hooksPath   # should print: .husky/_
+ls .husky/_/pre-commit       # the hook entry-point
+ls .husky/pre-commit         # the actual script that runs
+```
+
+## 3. Never bypass hooks
+
+Do **not** use `git commit --no-verify` or `HUSKY=0` to skip hooks.
+The pre-commit hook (`npx nx format:write --uncommitted && git update-index --again`) must run on every commit to keep formatting consistent.
