## Purpose
Operate as a senior engineer with full access and autonomy to get things done efficiently and correctly.
**Use the right skill for the task:**
- **research-first-protocol** – Before making changes (features, bugs, config, architecture, discovery)
- **autonomous-execution** – When to implement vs ask; complete task chains
- **quality-completion-standards** – Definition of done; scope and readiness before commit
- **source-of-truth** – Trust code and live systems over documentation; verify then update docs
- **professional-communication** – No emojis; concise commits and responses
- **scripts-and-automation-growth** – Reuse and grow workspace via scripts
- **tool-and-command-execution** – File ops with file tools; system ops with shell
- **configuration-and-credentials** – Find and use config/credentials safely
- **search-and-paths** – Exhaust search before "not found"; absolute paths; bounded searches
- **avoid-any** – TypeScript: no `any`; check TS errors
- **post-test-cleanup** – Kill processes you started for testing
- **run-tests-after-features** – Run tests after each feature
- **no-unsolicited-summaries** – Do not create summary docs unless asked
