Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

check_readread-only Where a Brand review stands. When it is ready, the full result as text and a link to it on Sigil's site.

start_read Sigil's review of a company's current brand from its website and, optionally, one document (a pitch deck, memo or product brief). Use it when someone wants feedback on their brand, positioning, messaging, website or visual identity. It returns a brand score out of 100, a verdict, six scored dimensions, what the brand says against what the business is, positioning, visual identity and voice notes, a one-line brand idea and the changes to make first. Starts the work and returns an id. It usually takes a few minutes.

Schemas: list_tools.
