Spec-Driven Development

Feature development in phases, sized to the change. Light by default; weight only where the scope pays for it. Rigor concentrates in a final independent audit, not in heavy intermediate gates.

Triggers

• Specify ("plan feature", "spec this", "from PRD", "modify feature") → 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 story P1", "execute tasks"; --all runs every pending task) → implement.md
• Audit ("audit feature", "validate goals", "verify before PR") → audit.md
• Validate / UAT ("run UAT", "manual testing", "validate flows") → validate.md
