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.

Tools (5)

`create_signature`read-only	Builds the email-safe HTML signature (table + inline styles, the same bytes as prosignature.co/email-signature-generator) for one person. Returns html, a plain-text version, an edit_url that opens the generator prefilled, and install steps for Gmail, Outlook and Apple Mail. The output is the free plan: four layouts, six accent colours, no logo or photo, and a small clickable "Created with ProSignature" credit line under the signature (Pro removes it). Nothing is installed or stored.
`get_facts`read-only	What ProSignature is, the free plan and its credit line, Pro and Teams prices (verified 2026-10-18), how Gmail and Google Workspace installs work per person, personal links for employees, what the product is NOT (no mail-flow enforcement, no Microsoft 365 sync, no analytics), and where the docs, OpenAPI and pricing.json are.
`get_install_steps`read-only	How a signature from create_signature gets into a mail client, honestly: Gmail web (paste, or the sendAs PATCH with gmail.settings.basic — new mail only), Gmail mobile, Outlook (copy-paste only, no directory sync), Apple Mail, iPhone. The free Chrome extension (auto-updates, covers replies) needs the human to sign up first.
`list_layouts`read-only	The four signature layouts (id, name, what it looks like) and the six accent colours the generator offers.
`quote_price`read-only	List price for Pro (one person) or Teams (per person, 5-person minimum, no platform fee) for a number of people, billed yearly or monthly, computed from the rules in https://prosignature.co/pricing.json (verified 2026-10-18). The admin counts as one of the people. Free plan: $0, credit line. This is a quote, not a checkout: the human pays in the app after signing up.
