secondbrain-freshness（第二脑新鲜感）

Freshness Report

Generate a comprehensive freshness report for all secondbrain entities.

Prerequisites

Verify secondbrain is initialized:

1. Check for .claude/data/config.yaml
2. If not found, indicate no secondbrain project found

Workflow

Step 1: Load Configuration

Read .claude/data/config.yaml to get:

• All enabled entities
• Freshness thresholds per entity
• Monthly partitioning settings

Step 2: Analyze Each Entity

For each enabled entity:

1. Load all records
2. Check date fields (created, date, date_updated)
3. Compare against freshness threshold
4. Categorize by staleness level:

- Critical (2x threshold): Needs immediate attention - Stale (1x threshold): Should be reviewed - Warning (0.75x threshold): Approaching staleness

Step 3: Generate Report

Format by entity and urgency:

Tips

1. Run weekly — Set calendar reminder for freshness reviews
2. Address critical first — Focus on oldest items
3. Archive liberally — Better to archive than ignore
4. Update thresholds — Adjust based on your workflow pace
5. Check after sprints — Good time to clean up stale items
