principle-guard-the-context-window
Apply when context is filling up: large outputs, long files, repeated reads, fan-out planning. Route bulk to subagents; keep summaries in the main thread, not raw payloads.
Why this skill is useful
Provides a structured approach to managing context window limitations, enhancing the AI's ability to handle large outputs and maintain reasoning quality.

What this skill does
Guard the Context Window The context window is finite and non-renewable within a session. Every token should be worth its cost. Why: Context overflow degrades reasoning quality, creates compression artifacts, and halts progress. Pattern: Isolate large payloads. Route verbose outputs, screenshots, and large documents to subagents. The main context gets summaries, not raw data. Keep frequently used content inline. Templates and references used on every invocation belong in the skill file, not in separate files that cost a read each time. Size phases and cap scope. Limit files per phase, set turn budgets, account for mechanism costs.
How to use it
