Context Usage Monitor

Purpose

Monitor and warn about context usage to prevent context exhaustion.

• 50k tokens: Strong warning (Orange)
• 70k tokens: Critical warning (Red) - Consider /clear

Monitoring Points

1. After each agent invocation
2. Before complex tasks
3. When reading large files

Warning Messages

Red (70k+)

Copy🔴 Context Usage: 70k+ tokens
CRITICAL: Use /clear soon to prevent errors.
Save important context before clearing.

Best Practices

1. Use subagents to preserve main context
2. Clear context between major features
3. Avoid reading unnecessary large files
4. Use Task tool for complex searches

Context-Saving Commands

git status > /tmp/context_save.txt
git diff --staged >> /tmp/context_save.txt

# After /clear, restore context:
