The README opens with

Send your model the tools it needs for this turn, not your whole catalog.

A Hermes Agent plugin that trims the tool schemas sent with each model request, with a dashboard to see how much it saves.

Quick start · How it works · Modes · Configure · Commands · Docs

Every model call in Hermes carries the full JSON schema of every enabled tool. With dozens of native and MCP tools, that is often 15–20k tokens per request, resent on every step of every turn. Tool Slimmer ranks the tools against what you actually asked and sends only your always-on tools plus the best matches.
