What problem does it solve? When you encounter an unfamiliar repository, it is hard to quickly understand its purpose, architecture, and key logic without reading every file. This Skill guides a systematic investigation and produces a grounded first-look report. ## Core Features & Use Cases - Structured Investigation Workflow: Follows a six-step process from establishing project purpose to tracing data flows and recording uncertainty as UNKNOWN with the smallest check to resolve it. - Tailored Report Sections: Covers overview, architecture, code structure, key components, algorithms, testing strategy, documentation quality, and risks, using only sections the repository supports. - Evidence-Based Claims: Cites paths and symbols, uses Mermaid diagrams when they clarify boundaries, and avoids inferring behavior from filenames alone. - Use Case: You clone an open-source project you have never seen and ask for an architecture overview; the Skill inspects entry points, traces flows, and returns a compact report with cited evidence. ## Quick Start Ask the assistant to analyze this repository and produce a first-look report covering its architecture, key components, and risks.
