Context Sentinel

This skill provides a script to automate the "Cascading Model Protocol," ensuring the agent gracefully degrades from high-cost models to high-context models as the session grows.

Protocol Summary

1. Opus 4.6: Use until 80% context, then switch to Opus 4.5.
2. Opus 4.5: Use until 80% context, then switch to Gemini 2.5 Pro.
3. Gemini Pro: Use until 80% context, then trigger a handoff.

This skill operationalizes the logic defined in MEMORY.md.

How to Use

This skill is designed to be run periodically, either via a cron job or as part of the main agent's HEARTBEAT.md checklist.
