The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
lean_read Lean Reader ~147
Fetch a URL and return token-minimized clean text plus a token-savings receipt. Strips nav/scripts/boilerplate so an LLM reads the article, not the page. The receipt counts tokens vs the raw page HTML (typically ~15x fewer, but it ranges from ~1.5x on already-clean pages to 100x+ on script-heavy docs). Two extractors (Defuddle + Readability), body-max selection, so it does not silently drop the article body. Static HTML only — JS-rendered pages may come back partial.
| Name | Type | Req | Description |

| format | string | – | Output format (default: markdown) |
| url | string | yes | The URL to fetch and clean |
