Spec Driven

A structured workflow that adapts depth to scope: small fixes skip straight to implementation, medium changes get spec and tasks, complex features get the full pipeline with design docs. The interesting bit is the verification chain that forces you to check the actual codebase and project docs before searching the web or asking questions. It enforces audit before PR, not after, and runs verification inside each task implementation rather than as a final phase. The anti-patterns section is unusually honest about what breaks the workflow. Built around three artifacts (spec.md, design.md, tasks.md) with requirements traceability back to goals and success criteria. Useful when you want guard rails that scale down for quick fixes instead of forcing ceremony on everything.

Spec-Driven Development

Feature development in phases. Light by default; weight only where the change pays for it.

Triggers

Specify ("plan feature", "spec this", "from PRD", "modify feature", "discuss how to build") → specify.md
Design ("design this feature", "technical design", "plan the build") → design.md
Tasks ("create tasks", "break into tasks", "task breakdown") → tasks.md
Implement ("implement task T-1", "implement T-1 to T-4", "implement slice S-1", "execute tasks", "implement everything") → implement.md
Validate / UAT ("run UAT", "manual testing", "validate flows") → validate.md
Archive ("archive feature", "archive this spec") → archive.md

Workflow
