Session Limits, Checkpoints, and Resume
Manage long-running sessions — time, checkpoints, resume, abort.
What You Will Learn
- Understand session limits.
- Use checkpoints effectively.
- Resume interrupted sessions.
- Abort safely.
- Track session metrics.
Why This Matters
Agent sessions can run minutes to hours. Knowing how to manage them — checkpoints, resume, abort — prevents wasted work and frustration.
Concept Explained
Agent sessions have time limits (varies by plan). Checkpoints let you resume if interrupted. Abort stops cleanly. Track metrics: time, credits, success rate.
How It Works
Monitor session progress. If near limit, agent checkpoints automatically. You can manually checkpoint. Resume from checkpoint. Abort if going wrong.
Step-by-Step Tutorial
1. Know session limits
Varies by plan. Pro: shorter; Pro+/Max: longer. Check docs.2. Monitor progress
Agent shows progress. Check every 30 min.3. Checkpoints
Auto at intervals. Manual via UI.4. Resume
If interrupted (network, plan limit), resume from checkpoint.5. Abort
If going wrong, abort. Branch is preserved; you can inspect partial work.6. Track metrics
Time per task, credits used, success rate.Real-World Example
A team delegated a complex refactor. Session hit time limit at 45 minutes with 60% done. Checkpoint saved. Resumed next day; completed in 20 more minutes. Without checkpoint, would have lost 45 minutes of work.
Example Prompts / Commands / Code
1. Delegate task to agent.
2. Monitor every 30 min:
- Is progress being made?
- Are edits sensible?
- Any errors?
3. If near limit:
- Agent auto-checkpoints.
- Or you manually checkpoint.
4. If interrupted:
- Resume from checkpoint.
5. If going wrong:
- Abort.
- Inspect partial work in branch.
- Decide: iterate or fix manually.
6. Track metrics:
- Time per task
- Credits used
- Success rate (PR merged?)
- Common failure modes
Task Time Credits Result
----------------------------------------------------
Add null check 8 min 50 PR merged
Add tests 12 min 80 PR merged
Refactor function 45 min 300 PR merged (after resume)
Convert callbacks 60 min 400 Aborted (too complex)
Add docstrings 20 min 100 PR merged
Avg time: 29 min
Avg credits: 186
Success rate: 80% (4/5 merged)
Common Mistakes
- Not monitoring — sessions can go wrong silently.
- Not using checkpoints — lose work on interruption.
- Not aborting when going wrong — wastes credits.
- Not tracking metrics — can't improve delegation.
Best Practices
- Monitor every 30 min.
- Use checkpoints (auto and manual).
- Resume from checkpoint on interruption.
- Abort if going wrong — inspect partial work.
- Track metrics: time, credits, success rate.
Troubleshooting
| Problem | How to Fix |
|---|---|
| Session interrupted | Resume from checkpoint. If no checkpoint, restart. |
| Agent stuck | Abort. Inspect branch. Refine issue. Re-delegate. |
Practical Exercise
Your Turn
Delegate a task. Monitor progress. Note checkpoints. Track time and credits. Document the experience.
Professional Challenge
Build a session metrics tracker: time, credits, result. Track over 10 delegations. Identify patterns.
Key Takeaways
- Sessions have time limits (varies by plan).
- Checkpoints (auto + manual) save work.
- Resume from checkpoint on interruption.
- Abort if going wrong; inspect partial work.
- Track metrics: time, credits, success rate.
