Turns out the filesystem is a better context manager than your prompt. This skill shows you how to offload tool outputs, persist plans, and share state between agents using files instead of cramming everything into the context window. The core insight is simple: write once, retrieve selectively. Tool returned 10,000 lines? Write it to scratch, grep for what you need, pull 50 lines back. Long task losing coherence? Persist the plan as YAML and re-read it each turn. The pattern library covers scratchpads, sub-agent handoffs, dynamic skill loading, and self-modifying instructions. It's practical filesystem engineering for context-constrained agents, with clear guidance on when to use files versus actual memory systems.
