What problem does it solve? Research notes often contain scattered equations, mixed approximations, and unclear assumptions that cannot be turned into a coherent theory line. This Skill organizes them into an honest derivation package instead of a fake polished theorem story. ## Core Features & Use Cases - Derivation Structuring: Freezes the target, chooses an invariant object, normalizes assumptions and notation, and builds a derivation map before writing. - Honest Step Classification: Labels every step as identity, proposition, approximation, or interpretation, and marks gaps in an Open Risks section. - Status Reporting: Outputs COHERENT AS STATED, COHERENT AFTER REFRAMING, or NOT YET COHERENT with a blocker report when the notes cannot support a derivation. - Use Case: You have messy theory notes mixing exact algebra and heuristics. The Skill rewrites them into a DERIVATION_PACKAGE.md with target, assumptions, derivation map, main steps, and boundaries ready for paper drafting. ## Quick Start Ask the assistant to turn your current formula notes into a coherent derivation package targeting DERIVATION_PACKAGE.md.
