What problem does it solve?
This Skill helps developers, reviewers, and onboarders move from surface-level reading to true understanding by turning opaque code and feature areas into clear mental models. It prevents shallow explanations and reduces knowledge gaps that cause repeated questions, buggy changes, and slow onboarding.
Core Features & Use Cases
- Feynman Loop Workflow: Iterative explore → explain → find gaps → re-explore to converge on clear, testable explanations.
- Codetrace & Mapping: Trace entry points, call flows, dependencies, and side effects across files to reveal design intent and risks.
- Practical Use Cases: Onboard new team members to a service, prepare a design doc by extracting rationale from code, or explain a failing feature during debugging.
Quick Start
Ask the assistant to explain how the authentication feature works by tracing entry points, data flow, and key design decisions.
