name: git-manager description: Advanced Git operations support for bisecting regressions, cleaning up branches, managing stash workflows, and analyzing commit/history state. Use when users ask for "git bisect", branch cleanup, stash recovery/organization, reflog or log analysis, or safe handling of destructive/history-rewriting commands.

git-manager

Summary

git-manager orchestrates advanced repository maintenance by combining bisecting, branch cleanup, stash handling, and log analysis into a cohesive guidance skill. It keeps teams safe by pairing every destructive recommendation with an explicit verification or rollback prompt before running commands that rewrite history.

Triggers

• git manager
• bisect issue
• cleanup branches
• stash help
• analyze git log
• safe git ops

Workflow

1. Assess repository health – start with git status, review git fetch --all, and record the current branch/tag. Prompt the user: "Are we on the branch that should move forward, or is a temporary diagnostic branch mounted?"
2. Bisect troubleshooting – when isolating regressions, run git bisect start with the known good/bad commits and iteratively test. After each reproduce attempt, ask for confirmation before git bisect good/bad. Offer the safety reminder: "Bisect rewrites HEAD; stash or commit open work first."
3. Branch cleanup – use git branch --merged versus git branch --no-merged to find stale branches. Recommend git branch -d <branch> for merged work and git branch -D only after re-confirming the target branch via a safety prompt to avoid deleting active work.
4. Stash management – suggest git stash list/git stash show to catalogue hidden work. Encourage naming stashes with git stash push -m "description" and verify the exact entries before git stash drop/pop, reminding the user to keep a copy (git stash branch <name>) if they need extra safety.
5. Log analysis – guide through git log --oneline --graph --decorate, git reflog, and git log @{u} to understand recent operations. Offer commands like git show <commit> for inspection and highlight the importance of reviewing commit messages before reverting or cherry-picking.
6. Safety prompts – before destructive commands (e.g., reset --hard, git clean -fd, branch deletion, rebase, push --force), run the two-step destructive confirmation protocol: (1) display the current branch name and HEAD commit hash or tag, verify the target commit, and remind the user to take a backup action (tag, temporary branch, stash, export patch, etc.); (2) require an explicit textual YES reply before running the command. Always pair the recommendation with git status, git log -1, or a git tag snapshot so the user can see exactly what would change, and prefer git push --force-with-lease over --force unless the situation explicitly warrants the risk.

Deliverables

• Provide step-by-step command sets for diagnostics (bisect, log review, stash recovery).
• Keep a safety checklist in every response: check HEAD, stash status, remote tracking state, and backup plan (tag or branch) before rewriting history.
• Offer follow-up summary: what was touched, what is stashed, and what commands to run next for cleanup.
