+2. Create a focused branch using the task ID.
 3. Keep changes scoped to the selected task.
 4. Update the task checklist when the task is complete.
 5. Run the strongest available verification commands.
 6. Open a pull request that links the issue.
 
+## Branch Naming
+
+Use a short branch prefix that matches the work type, followed by the task ID and a concise slug:
+
+```text
+feat/ad-101-agent-schema
+fix/ad-402-runtime-events
+docs/ad-1001-basic-agent-workspace
+chore/ad-1002-contributor-workflow
+```
+
+Use `feat/` for product behavior, `fix/` for defects, `docs/` for documentation or examples, and `chore/` for repository workflow or maintenance changes.
+
+## Commit Style
+
+Use conventional, imperative commit messages:
+
+```text
+feat: add workflow canvas mvp
+fix: stabilize daemon event cleanup test
+docs: add basic agent workspace example
+chore: add contributor workflow
+```
+
+Keep each commit focused on one task. Include docs, tests, and task checklist updates in the same commit when they are part of the task completion.

 ## Security-Sensitive Changes
 
 Changes involving daemon execution, runtime adapters, workflow patches, permission policy, audit logs, or secret redaction require extra scrutiny and tests.
