Summary
Condense verbose tool descriptions to reduce system prompt token overhead.
Estimated savings: ~3,000–4,000 tokens per message.
Changes

These files are included in the system prompt for every message. Reducing their length significantly cuts per-message token cost without changing tool behavior or removing safety rules.
