Search users

search_users
Read-onlyIdempotent

Search users by name or email to get their ID, enabling you to query pages and manage groups with the correct user reference.

Instructions

Finds users by name or email. Use it to resolve a person to the id that list_pages (creator_id, author_id) and the group tools take.

TDQS

A3.8/5.0
Behavior3/5

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

Annotations already declare readOnlyHint, idempotentHint, and non-destructive behavior, so the description does not need to restate safety. It adds the operational context that the returned user id can feed list_pages and group tools, but it does not disclose matching semantics such as partial match behavior, case sensitivity, or handling of multiple/no matches.

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 core action first and the use case second. Every phrase earns its place.

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?

For a one-parameter read-only search tool with an output schema, the description is nearly complete: it states the query input, the search fields, and the downstream use of the result id. It only lacks explicit guidance on ambiguous results or empty result sets, which is minor given the output schema and annotations.

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%: the query parameter is already documented as 'Name or email fragment.' The description's 'name or email' adds no new semantic detail beyond the schema, so the high-coverage baseline of 3 applies.

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?

The description opens with a specific verb and resource: 'Finds users by name or email', so an agent immediately understands the search function and criteria. It further clarifies the intended purpose by saying to resolve a person to the id that list_pages and group tools take, but it never name-checks sibling tools like list_users or get_user to explicitly differentiate from 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?

It explicitly instructs when to use the tool: 'Use it to resolve a person to the id that list_pages (creator_id, author_id) and the group tools take.' This gives a concrete trigger condition. It does not, however, state when not to use it or name alternatives such as list_users/get_user, so it stops short of a 5.

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