From Agentic SDD (Spec-Driven + TDD)
Use when starting any non-trivial feature or change, to run the Spec-Driven Development loop — write a testable spec, derive tests, implement, and verify against the spec. Trigger on "spec", "SDD", "new feature", "requirements", or when work should start from a written contract rather than ad-hoc coding.

The spec is the source of truth. Tests encode the spec; code satisfies the tests. Work flows in one direction and every step traces back to a numbered acceptance criterion.

architect agent first to produce docs/design/<feature>.md and ADRs.spec-writer produces specs/<feature>.spec.md: summary, user stories, functional + non-functional requirements, numbered Given/When/Then acceptance criteria (AC-n), edge cases, out-of-scope, and a Definition of Done.tdd-test-writer turns each AC-n into failing tests that reference the AC id. Confirm they fail for the right reason.implementer writes the minimum clean code to pass.e2e-tester covers the criteria marked "needs E2E" through real interfaces.code-reviewer checks AC coverage, clean code, security, performance.AC-n maps to a passing test; the Definition of Done is met.See references/spec-template.md for the canonical structure. Place specs in specs/, designs in docs/design/, decisions in docs/adr/.
