# PR Research Skill Systematic exploration of upstream repositories before contributing. ## Overview Research an external codebase to understand how to contribute effectively. This is the FIRST step before planning or implementing an open source contribution. **When to Use**: - Before contributing to an external repository - Starting a new open source contribution - Evaluating whether to contribute to a project **When NOT to Use**: - Researching your own codebase (use `$research`) - Already familiar with the project's guidelines --- ## Workflow ``` -1. Prior Work Check -> BLOCKING: Check for existing issues/PRs 0. CONTRIBUTING.md -> MANDATORY: Find contribution guidelines 1. Repository Setup -> Clone/identify upstream repo 2. Guidelines Analysis -> Templates, CODE_OF_CONDUCT 3. PR Archaeology -> Analyze merged PRs, commit patterns 4. Maintainer Research -> Response patterns, review expectations 5. Issue Discovery -> Find contribution opportunities 6. Output -> Write research document ``` --- ## Phase -1: Prior Work Check (BLOCKING) **CRITICAL**: Before ANY research, check if someone is already working on this. ```bash # Search for open issues on this topic gh issue list -R <owner/repo> --state open --search "<topic keywords>" --limit 20 # Search for open PRs that might address this gh pr list -R <owner/repo> --state open --search "<topic keywords>" --limit 20 # Check for recently merged PRs (might already be fixed) gh pr li
