Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

listing
check_listing
Runs FirstPass Memo's 33 published red-flag rules on a small online-business listing (SaaS, content site, ecommerce, Amazon FBA, newsletter, app; roughly $10k-$150k) from Flippa, Empire Flippers, Acquire.com or any broker. Pass the listing text the user provides and/or the key numbers. Returns payback in months, the asking multiple vs comparable listings, every flag that fired (severity, why it matters, link to the rule) and questions to ask the seller. Screening only: not advice, a valuation or verification. Does not fetch URLs.
rules
list_rules
Returns the 33 published rules the checker uses (code, title, group, severity, when it fires, explainer URL).
