git-undo

A command for recovering from Git mistakes, including misplaced commits, lost changes, deleted branches, force pushes, and broken rebases.

In plain words
What is it for?
Use it to inspect the repository state and choose commands for restoring commits, branches, staged files, or previous versions.
Why use it?
It helps identify what happened by checking Git history and the reflog, which records earlier reference positions, before suggesting a recovery path.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

git-undo scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 103 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/git-undo

Recover from any Git mistake. Tell me what happened and I'll help you fix it.

What I Need From You

Describe what went wrong:

  • "I accidentally committed to main"
  • "I did a hard reset and lost my changes"
  • "I force pushed and overwrote my colleague's work"
  • "I deleted a branch with unmerged commits"
  • "I rebased and now everything is messed up"

Recovery Workflow

Step 1: Assess the Situation

First, I'll check your current Git state:

# Current branch and status
git status

# Recent history
git log --oneline -10

# Reflog (your safety net)
git reflog -20

Step 2: Identify Recovery Path

Based on your situation, I'll recommend one of these recovery methods:

Situation Recovery Method
Committed to wrong branch git cherry-pick or git reset --soft
Lost commits after reset git reflog + git reset
Force push overwrote remote git reflog + coordinate with team
Deleted branch git reflog + git checkout -b
Bad rebase git reflog + git reset --hard ORIG_HEAD
Accidentally staged files git restore --staged
Want to undo last commit git reset --soft HEAD~1

Step 3: Execute Recovery

I'll provide the exact commands with safety checks:

  1. Create backup branch first (always)

    git branch backup-$(date +%Y%m%d-%H%M%S)
    
  2. Execute recovery commands

  3. Verify the fix worked

    git log --oneline -5
    git status
    

Common Scenarios

"I committed to main instead of my feature branch"

# Save the commit hash
COMMIT=$(git rev-parse HEAD)

# Reset main to before your commit
git reset --hard HEAD~1

# Switch to feature branch and apply commit
git checkout feature-branch
git cherry-pick $COMMIT

"I lost commits after git reset --hard"

# Find lost commits in reflog
git reflog

# Look for your commit message, then:
git reset --hard HEAD@{n}  # n = number from reflog

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
