Input Schema

NameRequiredDescriptionDefault
limitNoMaximum records to return (1-100). Each returned record costs one credit.
sinceNoReturn companies created/updated on or after this date (YYYY-MM-DD) or ISO-8601 timestamp.
cursorNoOpaque pagination cursor returned as pagination.nextCursor on the previous page.
domainNoExact company domain.
searchNoKeyword search over name, domain, and description.
countriesNoHeadquarters country codes (ISO alpha-2, OR). Pass "unknown" to include companies with no country on file.
naicsCodeNoNAICS 2022 code. Matches the code and everything beneath it, so "51" also returns 5132 and 5173. Sector ranges work: "31-33" returns all manufacturing. Pass "unknown" for unclassified companies. Any 2- to 6-digit code is accepted; codes deeper than we classify (e.g. 541511) match at their deepest classified parent (5415).
includeTotalNoAlso return pagination.total, the number of records matching these filters across all pages. Costs no credits.
foundedYearMaxNoMaximum founded year.
foundedYearMinNoMinimum founded year.
industryGroupsNoCompany industry groups (OR). LinkedIn industry labels, matched case-insensitively; older LinkedIn names and short forms like "software" map to the current label. Pass "unknown" for companies with no industry on file.
employeeCountBucketsNoLinkedIn employee count buckets (OR), e.g. 51-200. Pass "unknown" for no headcount.

TDQS

A3.9/5.0
Behavior4/5

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

Annotations already declare readOnly/openWorld/non-destructive, so the burden is lighter, and the description adds genuinely new behavioral information: one credit per returned record, which directly affects how the agent sets limit. It omits anything about rate limits, auth, or pagination behavior, keeping it below a 5.

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?

Two sentences, zero filler, with the filter surface front-loaded and the cost constraint in the second position before the agent commits to a limit.

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

Completeness5/5

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

For a 12-parameter read-only search whose schema is fully documented and whose safety profile is carried by annotations, the description supplies the two things the schema can't: the overall filter inventory and per-record credit cost. Return-value detail is not needed since the schema's includeTotal/cursor descriptions cover pagination.

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 description coverage is 100% and the schema itself explains matching semantics (NAICS prefix matching, 'unknown' values, OR-merging, credit cost of limit). The description only restates the filter list in prose, adding no syntax or matching detail beyond the schema.

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 (search/filter) and resource (company records) and enumerates the exact filter dimensions, which clearly separates it from event-oriented siblings like funding_events or company_timeline. It stops short of naming a sibling to route against, so it is clear but not fully differentiated.

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 phrase 'search and filter company records' tells the agent this is the entity-lookup entry point, and the credit-cost note hints at budgeting via limit. There is no explicit when-to-use, when-not-to-use, or named alternative tool.

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