What problem does it solve? When triaging bug reports or feature requests, developers waste time manually hunting through large codebases to find the files that actually need to change. This Skill automates that exploration, producing a verified list of primary source files, related files, and applicable test files. ## Core Features & Use Cases - Hypothesis-Driven Exploration: Forms an initial hypothesis from the issue title and body, then explores the full repository structure rather than a single subfolder. - Cross-Package Tracing: Follows imports, stack traces, and data flow across package boundaries (e.g., packages/cli and packages/core) to capture all affected callers and consumers. - Test Applicability Check: Searches for existing test patterns (e.g., *.test.ts) and marks test_file as "N/A" with manual verification steps when automated tests do not apply. - Use Case: Given a GitHub issue with a stack trace, the Skill traces the error to its source definition, identifies sibling files needing coordinated changes, and outputs a structured JSON summary for the next triage step. ## Quick Start Explore the repository for the attached bug report and return the primary source files, related files, and applicable test file as JSON.
