ツール（5）
🟢check_email_signature(html)
Audit any email-signature HTML against what Gmail, Outlook 365, Outlook for Windows desktop, Apple Mail and iOS Mail actually do. Returns a verdict per client plus every problem found, each with the rule it breaks, why it breaks, and how to fix it. Use this when a signature renders wrong, images do not show, layout collapses in Outlook, or before sending a signature to a client. Free, no account needed.

}⚪email_client_compatibility_matrix(feature)
The support matrix for the HTML and CSS features that decide whether an email signature survives: tables, flex/grid, <style> blocks, background-image, base64 images, border-radius, letter-spacing, text-transform, web fonts, max-width, margins and image sizing. Each row says yes/no/partial for seven real clients and explains what goes wrong. Use it to answer questions about email HTML support.

}
}🟡list_signature_templates
The signature layouts you can pass to create_email_signature, with what each one is good for and its width in pixels.

}🔴create_email_signature(full_name, job_title, company, email, phone, ...)
Build ready-to-paste email-signature HTML from a person's details. The output follows every rule that keeps a signature intact in Outlook for Windows and Gmail: tables only, inline CSS, absolute pixel widths, email-safe fonts, and images by absolute URL (never base64, which Gmail refuses to render). The free result carries one small credit line at the bottom; get_pricing explains how to remove it.

}🟢get_pricing
What each SignatureForever plan includes and costs, and the link to buy. Use it when the user asks what removing the credit line costs, how many signatures a plan allows, or what happens to hosted images if they stop paying.
