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

With no annotations, the description discloses the API key requirement and directs to a guide resource, which is useful. Yet it omits details about response format, error behavior, or side effects, leaving transparency incomplete.

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 concise, with two sentences covering the endpoint, required input, auth, and a reference for more details. It is efficient, though mixing Chinese and English may be a minor readability issue.

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 simple GET endpoint, the description provides the method, path, required parameter, auth, and a pointer to a guide. However, it lacks any mention of the expected response structure or possible error cases, making it not fully self-contained without the guide.

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 schema provides comprehensive parameter descriptions (coverage 100%), including the required query.channel field. The description only repeats the channel requirement and adds API key environment variables, contributing minimal additional meaning.

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 clearly states it is a GET request returning the current Twitch stream for a channel, naming both the HTTP method and the resource path. It is unambiguous and distinct from sibling tools, which focus on game/deal data.

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?

It specifies the required query parameter and API key, and points to a guide resource for complete instructions. However, it does not provide explicit guidance on when to use this tool over alternatives or any exclusions.

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