Don Cheli: Context Health Monitor

Instructions

1. Estimate the current context window usage based on:
   • Files loaded in the current session
   • Conversation length (turns × average tokens)
   • Any large outputs already in context
2. Report usage as a percentage of the model's context limit
3. Apply thresholds from the global rules:

   • 50K tokens in a result → recommend isolating in subagent

   • 200K session tokens → recommend summarizing and compressing context

4. Identify the highest-cost items in the current context:
   • Large file reads
   • Repeated content
   • Verbose tool outputs that could be summarized
5. Recommend specific actions:
   • Which files can be evicted (already processed)
   • Which outputs should be summarized
   • Whether a subagent should handle the next task
6. If context is healthy (< 40% used), confirm and suggest no action
7. Never truncate or discard context without explicit user confirmation

Output Format

## Context Health — 2026-03-28T16:00Z

### Usage Estimate
- Current session: ~85K tokens
- Model limit: 200K tokens
- Usage: 42% ✅ (healthy)

### Largest Items
1. src/payments/processor.ts full read — ~8K tokens (can evict — already analyzed)
2. Test run output from 14:32 — ~12K tokens (can summarize — report saved)
3. Conversation history — ~18K tokens (normal)

### Recommendations
- No immediate action required
- If you add 3+ more large files, consider /dc:destilar to compress session notes
- Next heavy task: use a subagent to isolate output

### Warning Threshold
Will warn again at 70% usage (~140K tokens)
