Structured Planning

Verification-driven task decomposition with Sibyl-native tracking. Mined from 200+ real planning sessions: the plans that actually survived contact with code.

Core insight: Plans fail when steps can't be verified. Decomposition that lands in concrete checks survives contact with reality; abstract bullets don't. Tracking in Sibyl lets plans outlive the context window that produced them.

How to read this skill: the phases below describe the rhythm of a useful planning pass, not a procedure to march through. Skip planning entirely for small clear work, compress phases when the answers are obvious, and treat the first plan as a hypothesis. Replanning is the rule, not the exception.
