browse_voices

Read-onlyIdempotent

Find and browse public AI voices by display name; pagination separates namesakes.

Instructions

Browse public voices, optionally matching a literal display name. Multiple namesakes remain separate identities; follow Next call for more.

A3.8/5.0

Behavior4/5

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

Annotations already mark it as read-only, idempotent, and non-destructive, so the bar is lower. The description adds genuinely useful behavior: matching is literal, namesakes are not collapsed, and results require following a next call for additional entries. This goes beyond the annotations and warns about pagination and duplicate-looking names.

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, both earn their place: the first states purpose and query semantics, the second warns about namesakes and pagination. There is no filler or repetition of schema fields.

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 simple read-only browse operation, this covers the essential call decisions: public scope, literal query matching, identity semantics, and pagination. An output schema is absent, but the degrees of freedom are low (3 optional params) and annotations carry the safety profile. It is not exhaustive about response shape, but an agent has enough to invoke it correctly.

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?

The input schema has 0% property descriptions, so the description must compensate. It does explain that query is a literal display-name match, which is valuable, but limit and offset are only inferable from their names/defaults and receive no explicit description. The 'Next call' hint is a useful pagination signal but does not fully specify how limit/offset interact.

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 uses the specific verb 'Browse' with the resource 'public voices' and notes the optional literal display-name filter, so its scope is clear at a glance. It doesn't explicitly differentiate from siblings such as read_voice or browse_interests, but the 'public voices' framing makes confusion unlikely.

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?

It gives clear usage context: use this to list public voices, with an optional literal-name query, and it hints at pagination via 'follow Next call for more.' However, it never names an alternative (e.g., read_voice for a specific voice) or states when not to use this tool, so guidance is implied rather than explicit.

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