Protocol Integration
DECISION LOOP Position
This skill applies at step 5 of the DECISION LOOP:
1. CLASSIFY -> complexity? backup needed? tools?
2. PROTECT -> cp file file.bak (for configs, DBs)
3. MEMORY -> query relevant context + past failures
4. AGENTS -> check overlaps (if multi-agent)
5. SKILLS -> @Skill:git-forensics.md for domain-specific guidance
6. WORK -> implement (ALWAYS use worktree for ANY file changes)
7. REVIEW -> self-review diff before testing
8. TEST -> completion gates pass
9. LEARN -> store outcome in memory

Git Recovery Forensics
Detection
Keywords: "recover", "corrupted", "lost commit", "fix git", "reflog", "fsck", "broken repo"
Protocol
- BACKUP FIRST:
cp -r .git .git.bak - Check integrity:
git fsck --full --no-dangling - Check reflog:
git reflog(commits survive even after reset) - Check loose objects:
find .git/objects -type f - Recover from pack files if needed:
git unpack-objects < .git/objects/pack/*.pack - Try
git stash listfor stashed changes - Use
git log --all --onelineto find orphaned branches
Common Fixes
- Corrupted HEAD:
git symbolic-ref HEAD refs/heads/main - Missing objects:
git fetch origin && git reset --hard origin/main - Detached HEAD with work:
git reflogthengit checkout -b recovery <hash> - Broken index:
rm .git/index && git reset
Rules
- NEVER run destructive commands without
.git.bakbackup - Use
--dry-runfirst for any destructive operation - Check
git reflogbefore anything -- commits almost always survive - Use
git cat-file -t <hash>to inspect object types
