Specialist
Engineer
Engineer is your on-call developer. Describe the tool, integration or automation you need and it builds it properly — writing tests first, reviewing its own work for bugs and security, then deploying to a live URL.
What it does
How Engineer helps.
- Specs the requirements from a plain-language ask.
- Writes the tests first — happy path, edge cases, error states.
- Implements until every test passes (no skipping the discipline).
- Self-reviews for bugs, security holes and performance.
- Deploys to a live URL and hands you the link.
- Wires integrations — bookings to calendar, reminders, data flows.
Use cases
Engineer in the real world.
-
A tool, end to end
“Build me an expense tracker” → spec, tests (validation, balances, CSV export), build, self-review, deploy — a live URL in minutes.
-
A custom integration
Need two systems talking? It builds the integration test-first, handles the errors and rate limits, reviews for security, and ships.
-
Automate the busywork
Wires your bookings into your calendar and sets the reminder flow so it runs without you touching it.
In the chat
What Engineer sounds like.
- “Built the inventory tracker test-first — caught a race condition in review, fixed it. Live URL’s ready.”
- “Bookings now sync to your calendar and the reminder flow is on. Want a test run?”
Built from the global Coding agent — test-first builds with self-review and one-step deploy.
