Spec-Driven Implementation Skill

Purpose

Execute the planning artifacts produced by spec-driven-planning. The skill auto-detects which mode the feature is in and runs the matching playbook:

• Quick mode (plan.md exists) — follow bite-sized steps, run verification commands, commit. No RED-GREEN-REFACTOR. Tests welcome but not mandated.
• Full mode (tasks.md exists) — strict TDD per task: RED → GREEN → REFACTOR, traceability to REQ-### IDs, quality gates between tasks.

Activation Triggers

• User says "implement this feature", "let's code this", "execute the plan"
• User mentions "tasks", "TDD", or "execution"
• User uses /dev-workflow:spec with tasks or execute
• Planning phase is complete
