/checkpoint

Use the research-memory skill to create a checkpoint of the current project state.

Ask the user for a checkpoint name/description if not provided.

A checkpoint captures:

• Current timestamp
• Checkpoint name/tag
• Project state summary
• Recent work summary
• Active TODOs at this point
• Key metrics snapshot

Log the checkpoint to memory/checkpoints.md in this format:

## Checkpoint: [NAME] (YYYY-MM-DD HH:MM)

**Purpose**: [User's description]

**Project State**:
- Phase: [Current phase]
- Progress: [Brief summary]
- Open TODOs: X items
- Recent experiments: Y

**Key Metrics**:
- Total sessions: N
- Experiments run: M
- Decisions made: P

**Notable Context**:
- [Important note 1]
- [Important note 2]

After creating the checkpoint, confirm:

• Where it was saved
• How to reference it later
• Suggest using it as a comparison point

Use cases:

• Before major changes: /research-memory:checkpoint "Before refactor"
• Milestones: /research-memory:checkpoint "Paper draft v1 complete"
• Experiments: /research-memory:checkpoint "Baseline model finalized"
• Reviews: /research-memory:checkpoint "End of sprint 3"

Support optional arguments:

• --tag milestone : Mark as a milestone checkpoint
• --tag experiment : Mark as an experiment checkpoint
• --tag backup : Mark as a safety backup point
