git-graphlisted

Render the git branch graph for the current repository and explain the topology: active branches, merge points, divergences, and tags. ## Usage - `/git-graph` (defaults: last 30 commits, all branches) - `/git-graph 50` (last 50 commits) - `/git-graph 20 main` (last 20 commits on main only) ## Context - Current directory: !`pwd` - Current branch: !`git branch --show-current` - Branch limit: !`echo "${1:-30}"` - Branch filter: !`echo "${2:---all}"` - Graph: !`git log --graph --oneline --decorate ${2:---all} -${1:-30} 2>/dev/null` - All local branches: !`git branch -v 2>/dev/null` - Remote tracking branches: !`git branch -rv 2>/dev/null | head -20` - Tags (recent): !`git tag --sort=-creatordate 2>/dev/null | head -10` - Unpushed commits: !`git log origin/$(git branch --show-current)..HEAD --oneline 2>/dev/null || echo "(no upstream)"` ## Your Task Present the branch graph clearly and annotate key topology features. **DO:** - Display the raw graph output from Context verbatim in a code block first - Identify the current HEAD position and active branch - Call out merge commits and what branches they merged - Highlight divergence points (where branches split from a common ancestor) - Note any tags and what they mark - Flag unpushed commits on the current branch - Identify long-running branches vs short-lived feature branches - Note if the graph shows clean linear history vs complex merge topology **DO NOT:** - Re-run git commands already provided in Context — use the captur
