twitch_search_streams

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

Annotations already declare readOnlyHint=true, openWorldHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds nothing about authentication, rate limits, pagination, or response behavior, which is a significant omission for a search tool that requires client credentials. It does not contradict the annotations, but it also adds no behavioral context.

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?

The description is a single front-loaded sentence with no wasted text. It is structurally clean but too sparse to be informative, which is captured in other dimensions rather than penalizing conciseness.

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?

For a search endpoint with five undocumented parameters, including client authentication fields, the description is not complete enough to guide correct invocation. It does not explain how to scope results, how many results are returned, or what the response contains. Given no output schema, some return-value context would also be expected.

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?

There are 5 parameters and schema description coverage is 0%, so the description carries the full burden of explaining parameter meanings. It mentions none of them: first, game_id, client_id, user_login, or client_secret. This leaves critical usage details such as pagination and authentication undocumented.

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?

The description states a specific verb and resource: search live streams on Twitch. It is clear what the tool does at a high level, though it does not differentiate from close siblings such as twitch_search_games or twitch_get_stream. The absence of sibling routing information keeps it from a 5.

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?

The description provides no guidance on when to use this tool versus alternatives like twitch_get_stream, twitch_search_games, or twitch_top_games. It also does not mention prerequisites such as authentication or required filters. Usage must be inferred entirely from the name.

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