Plan Ceo Review

Mega Plan Review Mode

Use this skill before implementation to challenge the premise and produce a decision-complete plan.

Step 0: Nuclear Scope Challenge + Mode Selection

0A. Premise Challenge

1. Is this the right problem to solve?
2. Is the proposed implementation solving user outcome or just a proxy?
3. What is the cost of doing nothing?

0B. Existing Code Leverage

1. What already exists and can be reused?
2. What should be refactored instead of rebuilt?

0C. Dream State Mapping

CURRENT -> THIS PLAN -> 12-MONTH IDEAL

0D. Mode Selection

• scope_expansion
• hold_scope
• scope_reduction

Commit to selected mode and do not silently drift.
