Measured tools (6)

• list_categories read-only

  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.

  Parameters:

  • limit — integer
  • query — string — Optional filter matched against the category name and description.

  Hints: read-only yes · destructive no · idempotent not declared · open-world no

• search_products read-only

  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.

  Parameters:

  • query (required) — string — Product or brand name, e.g. "Bambu Lab X2D".
  • limit — integer

  Hints: read-only yes · destructive no · idempotent not declared · open-world no

• get_tier_list read-only

  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.

  Parameters:

  • category (required) — string — Category slug, e.g. "3d-printers".
  • tier — string — Optional. Return only this tier.

  Hints: read-only yes · destructive no · idempotent not declared · open-world no

• get_product read-only

  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.

  Parameters:

  • slug (required) — string — Product slug, e.g. "bambu-lab-x2d".
  • citation_limit — integer — How many citations to return, most notable first. The sentiment and speaker breakdowns always count every source regardless of this.
  • citation_offset — integer — Skip this many citations. Use it to page through the rest.

  Hints: read-only yes · destructive no · idempotent not declared · open-world no

• compare_products read-only

  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.

  Parameters:

  • slugs (required) — array — Product slugs to compare.

  Hints: read-only yes · destructive no · idempotent not declared · open-world no

• what_to_avoid read-only

  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.

  Parameters:

  • category (required) — string — Category slug, e.g. "3d-printers".

  Hints: read-only yes · destructive no · idempotent not declared · open-world no
