Checkpoint Skill

Purpose

Save, compare, and restore work state when necessary using Git stash/commit-based lightweight checkpoint system.

Core Principle: Always checkpoint before risky work → Safe experimentation → Rollback if needed

Activation Triggers

• Before risky refactoring
• Before starting experimental changes
• On major milestone completion
• Before PR submission (save final state)
• User explicit request: /checkpoint, checkpoint, save

Commands

Create Checkpoint

/checkpoint create <name>

Actions:

1. Verify current state is clean
2. Create stash or commit if changes exist
3. Record in .claude/checkpoints.log
4. Save timestamp and Git SHA

Example:

/checkpoint create before-auth-refactor

✅ Checkpoint Created
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Name:      before-auth-refactor
Time:      2025-01-26 14:30:22
SHA:       a1b2c3d
Files:     12 staged, 3 modified
Status:    Clean state saved
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Verify Against Checkpoint

/checkpoint verify <name>

Actions:

1. Find saved checkpoint
2. Compare with current state
3. Report change metrics

Example:

/checkpoint verify before-auth-refactor

📊 Checkpoint Comparison
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Checkpoint:    before-auth-refactor
Created:       2025-01-26 14:30:22
Current SHA:   d4e5f6g

📁 Files Changed: 8

📈 Test Coverage:
   Before: 78%
   After:  85% (+7%)

🧪 Tests:
   Before: 42 passed
   After:  47 passed (+5 new)
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

List Checkpoints

/checkpoint list

Example:

/checkpoint list

📋 Saved Checkpoints
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Name                    Time                 SHA       Status
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
before-auth-refactor    2025-01-26 14:30    a1b2c3d   ← HEAD~3
feature-complete        2025-01-26 12:15    x7y8z9a   ← HEAD~8
initial-setup           2025-01-26 09:00    m4n5o6p   ← HEAD~15
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Total: 3 checkpoints

Restore Checkpoint

/checkpoint restore <name>

Actions:

1. Backup current changes (auto stash)
2. Restore to checkpoint
3. Confirm restoration

Example:

/checkpoint restore before-auth-refactor

⚠️ Restore Confirmation
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
This will:
1. Stash current changes (auto-backup)
2. Reset to checkpoint: before-auth-refactor
3. You will lose: 8 file changes since checkpoint

Proceed? [y/N]

Clear Old Checkpoints

/checkpoint clear

Action: Keep only the most recent 5 checkpoints, delete the rest

Implementation Details

Checkpoint Log Format

.claude/checkpoints.log:

[2025-01-26T14:30:22] before-auth-refactor | SHA:a1b2c3d | stash@{0}
[2025-01-26T12:15:10] feature-complete | SHA:x7y8z9a | commit
[2025-01-26T09:00:05] initial-setup | SHA:m4n5o6p | commit

Git Commands Used

# Create checkpoint (commit-based)
git add -A
git commit -m "checkpoint: <name>"

# Create checkpoint (stash-based for uncommitted work)
git stash push -m "checkpoint: <name>"

# Verify
git diff <checkpoint-sha>..HEAD --stat

# Restore
git stash  # backup current
git checkout <checkpoint-sha>

# List
git log --oneline --grep="checkpoint:"

Workflow Integration

Typical Development Flow

/checkpoint create "start-feature"
    │
    ├─→ Implementation work
    │
    ├─→ /verify quick
    │
    ├─→ /checkpoint create "mid-feature"
    │
    ├─→ Risky refactoring
    │       │
    │       ├─→ Success → Continue
    │       │
    │       └─→ Failure → /checkpoint restore "mid-feature"
    │
    ├─→ /verify full
    │
    └─→ /checkpoint create "feature-complete"

With /verify

/checkpoint create "before-refactor"
... refactoring ...
/verify full
    │
    ├─→ ✅ Pass → Continue
    │
    └─→ ❌ Fail → /checkpoint restore "before-refactor"

With /feature-planner

Auto-checkpoint before each Phase:

Phase 1 start → /checkpoint create "phase-1-start"
Phase 1 complete → /checkpoint create "phase-1-complete"
Phase 2 start → /checkpoint create "phase-2-start"
...

Best Practices

Checkpoint Naming Rules

✅ Good:
- before-auth-refactor
- phase-2-complete
- pre-db-migration
- working-login-flow

❌ Bad:
- checkpoint1
- test
- temp
- asdf

Recommended Checkpoint Timing

Checkpoint Management

• Run /checkpoint clear when 5+ accumulate
• Use meaningful names
• Create checkpoints only in working states
