Skill: Implement Phase

What This Skill Does

Bridges the gap between planning and code. Takes a plan phase with its implementation plan and executes it systematically — step by step, with test verification after each step, and automatic plan status updates.

Without this skill, agents implement "freestyle" after reading a plan, often skipping steps, forgetting test runs, or not updating plan status. This skill enforces the discipline that makes plans actually useful.

When to Use

• After resume-plan has briefed you on the current phase
• After analyze-impact has confirmed it's safe to proceed
• When the user says "implement this phase" or "start coding"

Do NOT use this for exploratory coding or quick fixes — it's designed for planned, multi-step work.
