Plan Feature

Create a lightweight implementation plan for medium-scope features.

When to Use

• •Medium features (1-5 files)
• •Clear requirements, no UX exploration needed
• •Standard patterns apply

Artifacts

• •implementation_plan.md artifact
• •task.md updated via task_boundary

Approach

Phase 1: Discovery & Impact

1. •Proof of Understanding: Summarize feature in one sentence.
2. •Holistic Impact Analysis: What else might this affect?

Phase 2: Approach Evaluation

Generate 3-4 strategies.

Evaluate with brief Socratic Debate:

• •Proponent: Benefits, consistency with patterns
• •Adversary: Complexity, maintenance burden
• •Synthesis: Final selection

Phase 3: Design & Execution

File Changes Table

Phased Implementation

Break into atomic, testable steps.

Phase 4: Reflexion

Hostile Architect Review: Identify 3 tech debt risks.

Constraints

• •No code generation — plan only
• •Steps must be atomic and testable
• •No one-off patterns
