Read-onlyIdempotent

Discover publisher section labels across the indexed corpus, distinct-site counts, newly observed labels, conservative emerging signals and seven-day membership changes. Emerging requires ten estimated domain-name families, excludes known templates/duplicates and waits three days; this measures index observations, not adoption. Labels come from headings, not a fixed taxonomy. Heading presence describes content and does not certify a capability. Partial coverage and baseline status are reported.

Input Schema

NameRequiredDescriptionDefault
qNo
pageNoPage number. Anonymous result window: 250; free registered integrations: 1,000. Each page holds at most 100 records.
sortNocommon
actionNoActions are inferred from publisher content. They can overlap and do not prove a working integration, authorization or task success. Unclassified sites may be missing useful actions.
countryNoCountry: owner-declared or site-published address preferred; domain/hosting inference is a labeled fallback. ISO 3166-1 alpha-2 (XK supported), case-insensitive, or unknown. GET /v1/countries / list_countries lists counts. Not verified headquarters or markets served.
per_pageNo
sectionsNoPublisher section keys from list_sections; discovered dynamically from indexed headings.

TDQS

A3.7/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already cover readOnly/idempotent/non-destructive, and the description goes well beyond them: it defines the emerging qualification bar (ten estimated domain-name families, template/duplicate exclusion, three-day wait), warns that labels derive from headings rather than a taxonomy, and notes that heading presence does not certify capability plus partial/baseline coverage reporting. That is substantive disclosure about result trustworthiness that annotations cannot convey.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Dense but every clause carries information: the leading clause names the resource and payload, then the caveats follow. No filler sentences and no restatement of the tool name.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With annotations, an output schema and eight optional parameters, the caveats about interpretation are the right focus and are present. What is missing is routing context against the near-duplicate sibling explore_sections and any indication of result shape beyond the output schema, leaving the selection decision underspecified.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 50%: page, action, country and sections are documented in-schema, while q, sort, per_page and section_match are bare. The description partially compensates by explaining what the "emerging" sort represents and its thresholds, but adds nothing for q, per_page, or section_match semantics. Baseline 3 is appropriate for the half-documented schema plus partial enum explanation.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource: "Discover publisher section labels across the indexed corpus," and enumerates the payload (distinct-site counts, newly observed labels, emerging signals, seven-day membership changes). It never differentiates itself from the sibling explore_sections or list_categories, so an agent cannot tell from the description alone which of the three to pick.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Usage is only implied: the description tells you what the results mean ("this measures index observations, not adoption") but never says when to call this versus explore_sections or list_categories. There are no explicit exclusions or alternative routing, just interpretive caveats.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
