Context Checkpoint

Save critical context before /clear. Enables 50-70% token savings.

When to Checkpoint

  • Every 3 tasks (aggressive - preserves tokens)
  • Before switching feature areas
  • After resolving complex bugs
  • When response feels slow (context bloat sign)

Checkpoint Format

Write to .claude/checkpoint.md:

markdown
# Checkpoint: [TIMESTAMP]

## Sprint Status
[Sprint X: N/M complete]

## Completed This Session
- [Task]: [what was done]

## Key Learnings
- [Bug pattern]: [resolution]

## Next Priority
[Next task ID and title]

## Files Modified
- [file paths]

After Saving

Tell user:

code
💾 Checkpoint saved.

Run /compact now to reclaim ~40% tokens (keeps context summary).
Use /clear only at major transitions (reclaims ~70% but wipes context).

Auto-Restore

After /clear, read .claude/checkpoint.md and continue.

What to Preserve
