Changes things 1Claude Code: ask
  • pricing_benchmarksPricing statistics counted from the published pricing pages of audited cases: median first paid tier, free-tier prevalence, and which capabilities most often sit behind the paywall…No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    Pricing statistics counted from the published pricing pages of audited cases: median first paid tier, free-tier prevalence, and which capabilities most often sit behind the paywall. Products without a public price are excluded rather than estimated; no ranking or traffic figures exist here because those cannot be verified freely.
Only reads 2Claude Code: allow
  • get_caseFetch one audited case by slug: pricing tiers as published, the paid trigger, what to copy, what NOT to copy, and every evidence source with its URL and grade.No findings

    Why it is in this group

    • The name "get_case" says "get": a word for reading.
    Description, as the server wrote it
    Fetch one audited case by slug: pricing tiers as published, the paid trigger, what to copy, what NOT to copy, and every evidence source with its URL and grade.
  • search_casesSearch ProofStack's audited business-model case studies of small software products.No findings

    Why it is in this group

    • The name "search_cases" says "search": a word for reading.
    Description, as the server wrote it
    Search ProofStack's audited business-model case studies of small software products. Every case carries revenue and pricing claims linked to public sources with an evidence grade, plus an explicit list of what does NOT transfer to other builders.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
