+## Commits

+**Format:** Conventional Commits
+
+```
+<type>(<scope>): <short description>
+
+[body — optional]
+
+Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
+```
+
+| Type | When |
+|------|------|
+| `feat` | New feature or capability |
+| `fix` | Bug fix |
+| `bump` | Version number update |
+| `docs` | Documentation only |
+| `chore` | Maintenance, config, tooling |
+| `refactor` | Restructure, no behavior change |
+
+- One logical change per commit
+- Imperative mood: "add webhook handler" not "added"
+- Always `Co-Authored-By` when Claude wrote or co-wrote — use actual model name
+
+---
+
+## Branches
+
+`<agent>/<short-description>` — e.g. `codex/refactor-storefront`, `idun/sysadmin-skill`
+
+- Lowercase, hyphens only
+- Short-lived — merge or delete after work is done
+- Never commit directly to `main` for anything non-trivial
+
+---
+
+## Never
+
+- `--no-verify` — fix the hook instead
+- `--force` push to `main`
+- `git add .` or `git add -A` — stage specific files
+- Amend published commits
+
+---
+
+## Frequency
+
+Commit after each discrete, complete change — not batched at session end.
