Create and update AGENTS.md project rules. Use when authoring or amending the cross-tool conventions agents must follow.

Create and maintain a specification that states what to build, not how. Use when writing a spec, editing requirements, or defining acceptance criteria.

Drive implementation through the red-green-refactor cycle.
One test at a time. Each cycle is vertical — one test, one implementation, one refactor pass. Do not write multiple tests before implementing.
Mock at system boundaries (database, network, file system, external APIs), not between internal functions. Prefer real implementations when practical. If a test would survive a complete rewrite of the internals, it is testing the right thing.
