Implementation Prompt

# Implementation Prompt - PDCA Do Phase

Use this prompt to execute the plan following strict TDD discipline.

## Working Agreements (Quick Reference)

**Core Principles:**
- ✅ **Test-First**: Failing tests before production code (behavioral failures, not compilation errors)
- ✅ **Small Commits**: <100 lines, <5 files, one logical change
- ✅ **Follow Patterns**: Search and reuse existing abstractions
- ✅ **You Own It**: Review AI reasoning, intervene early, commit only what you understand

**Key Interventions:** "Where's the failing test first?" • "Is this commit too large?" • "Does this follow our patterns?" • "Are we staying on plan?"

## When to Use

- After the plan is approved and ready to implement
- At the start of the Do phase of PDCA cycle
