list_talents

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

With no annotations, the description does convey that this is a live read of the official site and that results are exhaustive including alumni, which is meaningful context. It does not disclose freshness, failure modes, or ordering, so the behavioral picture is partial.

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

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

A single dense sentence, front-loaded with the action and resource, then scope, then returned fields. No filler and nothing out of order.

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

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

An output schema exists, so return values needn't be explained, and the description nonetheless names the key fields. For a zero-parameter read tool the coverage is nearly complete, with only minor gaps around result ordering and empty/error behavior.

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

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

The tool takes zero parameters, so there is nothing for the description to disambiguate; baseline 4 applies. The description usefully characterizes what the fixed result set contains rather than leaving it blank.

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

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

States a precise verb and resource — returns a formatted list of every talent on the official hololive English site — and pins the scope down (all generations, branches, alumni) plus the fields returned (English name, Japanese name, profile URL slug). This clearly separates it from get_talent_profile, which is the per-talent detail tool.

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

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

Usage is only implied: the exhaustive-list framing signals this is the enumeration entry point and get_talent_profile is for details, but the description never says when to choose one over the other or when not to call it. There are no explicit exclusions or alternatives named.

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