+# pre-commit Argo CD hooks
+
+A small pre-commit hook repository with a base runner and discrete hook scripts under `scripts/<hook-id>/run.sh`.
+
+## Hooks
+
+### `write-argocd-repo`
+
+Creates or overwrites `.argocd/repo` in the repository where the hook is being run, then stages it into the current commit.
+
+The generated file contains:
+
+- `remote_origin_url=<origin-url>`
+- `branch=<current-branch-or-short-commit>`
+- one `workflow=<filename>` entry for each file directly under `.gitea/workflows`
+
+## Usage
+
+Add this to the consuming repository's `.pre-commit-config.yaml`:
+
+```yaml
+repos:
+  - repo: https://example.com/your-org/pre-commit-argocd-hooks.git
+    rev: v0.1.0
+    hooks:
+      - id: write-argocd-repo
+```
+
+For local development:
+
+```yaml
+repos:
+  - repo: local
+    hooks:
+      - id: write-argocd-repo
+        name: Write Argo CD repo metadata
+        entry: /absolute/path/to/pre-commit-argocd-hooks/scripts/base.sh write-argocd-repo
+        language: script
+        always_run: true
+        pass_filenames: false
+        stages: [pre-commit]
+```
