What problem does it solve? Answers about open-source libraries often rely on stale documentation or web snippets instead of actual source code. This Skill maintains durable, human-findable local clones of external repositories so answers are grounded in real implementation evidence with commit SHAs and file paths. ## Core Features & Use Cases - Local-first repo resolution: Searches an existing clone shelf and inventory file before any web search, normalizing URLs, owner/repo names, and package names to a consistent clone path layout. - Managed clone lifecycle: Clones missing repos with configurable transport (HTTPS/SSH) and depth (shallow/full), and updates existing clones according to a configurable policy that protects dirty working trees. - Evidence-based answers: Records commit SHA and working tree state before use, then cites file paths and line ranges from actual source code. - Use Case: When asked how a routing library handles navigation internally, the Skill locates or clones the repo, inspects the source and tests, and answers with the exact commit and file references. ## Quick Start Ask how a specific feature is implemented in a GitHub repository and have the answer grounded in its actual source code.
