Investigate and recover from Git history problems with hypothesis-driven, read-only-first methods: find when/where a bug or change was introduced (bisect, pickaxe, line-history blame), recover lost commits, branches, stashes and dropped work (reflog, fsck), and reason about what gc and expiry will delete. Use when someone asks "who/when/why did this change", "I lost my commits after reset/rebase/force-push", "find the commit that broke X", "recover a deleted branch or dropped stash", or "did this secret ever enter history". Not for everyday branching or merging (use git-workflow, git-merge-conflicts), and history rewriting or secret purges are out of scope until the user explicitly authorizes them.

From the source SKILL.md

Git almost never destroys data immediately. Commits that look "lost" are usually unreachable, not deleted, and they stay recoverable until reflog expiry and garbage collection remove them. Forensics is therefore a race against expiry plus a discipline: observe first, preserve, then change anything.

What this skill does

Git History Forensics is a community-contributed Claude Code skill in the storytelling sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/git-history-forensics/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when someone asks "who/when/why did this change", "I lost my commits after reset/rebase/force-push", "find the commit that broke X", "recover a deleted branch or dropped stash", or "did this secret ever enter history". Not for everyday branching or merging (use git-workflow, git-merge-conflicts), and history rewriting or secret purges are out of scope until the user explicitly authorizes them.
