What problem does it solve? Determining exactly which files a specific person contributed to on a feature branch is hard with plain git commands, especially when files were renamed or moved by other contributors during the branch's lifetime. This skill produces a clear audit table of an author's contributions relative to an upstream branch. ## Core Features & Use Cases - Exact author resolution: Matches the requested person to their precise git identity using git log or the GitHub MCP get_me tool, avoiding false matches on similar names. - Rename-aware tracing: Builds a rename map across all branch commits and walks it transitively, so contributions survive multi-hop moves like contrib/chat/ → agentSessions/ → sessions/. - Merge-diff classification: Reports only files that will actually land in the merge, labeling each as DIRECT or VIA_RENAME with line-change stats. - Use Case: Before merging a long-lived branch, a reviewer asks which files a specific engineer touched; the skill returns a markdown table with status, file path, and +/- line counts plus a summary total. ## Quick Start Ask the agent to find every file that a named author contributed to on your current branch compared to main, tracing contributions through renames, and return the results as a markdown table.
