- Plugin cache skills: should be installed through the plugin system, not copied from another machine.
- Runtime/build artifacts: `node_modules`, `dist`, `build`, `__pycache__`, temp output, generated test decks, logs, sessions, cookies, auth files, and database files.

## Excluded Skills

| Skill | Reason |

- `internal-comms` is a generic internal communications workflow template in this package; receivers should adapt organization-specific formats locally.
