Read-onlyIdempotent

Explore relationships between publisher headings. Edges count distinct listed sites sharing both labels. Pass section keys to return related labels and a bounded page of publishers; no sections returns aggregate clusters only. Discovery is monitored without automatic usage quotas.

Input Schema

NameRequiredDescriptionDefault
pageNoPage number. Anonymous result window: 250; free registered integrations: 1,000. Each page holds at most 100 records.
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.
connectionsNoSemantic adds inferred heading similarity as separate semantic_edges; original shared-heading counts remain unchanged.shared
include_sitesNoFalse returns only aggregate connections and counts, without individual publisher records.
section_matchNoall

A4/5.0
Behavior4/5

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

Annotations already cover the safety profile (readOnly, idempotent, non-destructive), so the bar is lower, yet the description adds real value: how edge weights are counted and that discovery traffic is monitored without automatic usage quotas. It doesn't describe result ordering or how the 250/1000 record windows interact with per_page, but that is documented in the schema.

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

Conciseness4/5

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

Four tight sentences, no filler, with the core relationship model stated first before the mode switch. Minor cost: 'bounded page' and 'monitored' are slightly opaque phrasings that force a re-read.

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

Completeness4/5

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

With an output schema present, return values need not be explained, and 8 mostly optional parameters are well covered by the schema. The description supplies the graph semantics and the with/without-sections contract, leaving only minor gaps such as how 'connections=semantic' changes result shape beyond the separate semantic_edges field.

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

Parameters4/5

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

Schema coverage is 75%, so baseline is 3; the description earns an extra point by explaining the effect of supplying sections versus leaving them empty and by implying include_sites behavior ('bounded page of publishers' vs 'aggregate clusters only'). It adds meaning beyond the field-level descriptions for the two most consequential parameters.

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?

Names a concrete verb ('explore') and a specific resource ('relationships between publisher headings') and defines what an edge means ('distinct listed sites sharing both labels'), which is genuinely differentiating. It does not explicitly contrast with the closest sibling (list_sections, similar_sites), but the schema reference to section keys from list_sections gives the agent enough to separate them.

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

Usage Guidelines4/5

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

Explicitly states the two operating modes: passing section keys returns related labels plus a bounded publisher page, while omitting sections returns aggregate clusters only. That is clear conditional guidance for the main decision. It stops short of saying when to prefer this over similar_sites or list_sections.

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