Changes things 1Claude Code: ask
  • what_to_avoidThe products the research placed in the bottom tiers, and the ones it deliberately entered as traps buyers cross-shop but should not buy.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.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    The products the research placed in the bottom tiers, and the ones it deliberately entered as traps buyers cross-shop but should not buy. Use it to answer "what should I not buy" and to check whether a product a user is considering was flagged.

    Annotations the server declares

    • readOnlyHint: true
    • destructiveHint: false

  • compare_productsCompare two to five products side by side.No findings

    Why it is in this group

    • The name "compare_products" says "compare": a word for reading.
    Description, as the server wrote it
    Compare two to five products side by side. They must share a category: LP is points on one category ladder and comparing across boards is meaningless, so a mixed request is refused rather than answered misleadingly.

    Annotations the server declares

    • readOnlyHint: true
    • destructiveHint: false
    • openWorldHint: false

    Why it is in this group

    • The name "get_product" says "get": a word for reading.
    Description, as the server wrote it
    Everything held on one product: its placement, verdict, pros and cons, GTIN barcodes, the announcement date where the maker published one, and a breakdown of how the cited sources read (how many were glowing, positive, neutral or negative, and whether they were outlets, named authors, video channels or forum owners). Then every citation in full, with a verbatim quote, who said it, and whether the link was fetched and confirmed. Use this when a claim needs backing up.

    Why it is in this group

    • The name "get_tier_list" says "get": a word for reading.
    Description, as the server wrote it
    The full S-to-F tier list for one category: every ranked product with its tier, rank, LP, verdict, pros, cons, citation counts, GTIN barcodes and, where the maker published one, the announcement date. This is the primary tool and one call answers a "what is the best X" question completely. Call get_product for the quotes behind a placement.

      description: "...g: slugs cannot be guessed reliably and every other tool takes one."

      What this check looks for
    Description, as the server wrote it
    List the product categories that have a published tier list, newest research first. Call this first when you do not already know the exact category slug: slugs cannot be guessed reliably and every other tool takes one.

    Annotations the server declares

    • readOnlyHint: true

  • search_productsFind ranked products by name or brand across every board.No findings

    Why it is in this group

    • The name "search_products" says "search": a word for reading.
    Description, as the server wrote it
    Find ranked products by name or brand across every board. Returns the slug, category and tier for each match, which is what get_product and get_tier_list need next.

    Annotations the server declares

    • readOnlyHint: true
    • destructiveHint: false
    • openWorldHint: false

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.
