What problem does it solve? Security audits and architecture reviews often fail because reviewers jump to vulnerability hunting with only gist-level understanding, leading to hallucinated findings, missed edge cases, and lost context. This Skill enforces a disciplined, ultra-granular context-building phase so every conclusion is grounded in actual code. ## Core Features & Use Cases - Line-by-Line Micro-Analysis: Applies First Principles, 5 Whys, and 5 Hows to every function block, documenting purpose, inputs, outputs, invariants, and assumptions. - Cross-Function Flow Tracing: Follows internal and external calls as one continuous execution flow, treating unknown external contracts as adversarial. - Structured Quality Gates: Ships with an output requirements spec, a completeness checklist, and a full worked example of a DEX swap function analysis. - Use Case: Before auditing a Solidity DeFi protocol, activate this Skill to systematically map state variables, trust boundaries, and end-to-end workflows, producing an evidence-linked mental model that the later vulnerability-hunting phase can rely on. ## Quick Start Use the audit-context-building skill to perform a line-by-line analysis of the contracts in this repository and build a complete architectural model before any vulnerability review.
