fetch_get_body

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

With no annotations, the description carries the burden of behavioral disclosure. It states 'Get', implying a read-only operation, but does not explicitly mention whether the request remains paused or if the body is available only once. It provides some context by specifying 'paused request' but lacks depth on side effects or failure modes.

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 that directly states the action and scope. Every word contributes, with no fluff or repetition.

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 tool with one parameter and no output schema, the description is adequate: it names the action, the target (response body), and the necessary condition (paused at Response stage). It does not explain the broader fetch workflow (e.g., fetch_enable), but that is not required for a standalone getter.

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 covers the only parameter (requestId) with a description 'Request ID from paused request', so schema coverage is 100%. The tool description adds little beyond that, only reinforcing that the request must be paused. Baseline 3 is appropriate.

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 uses a specific verb ('Get') and resource ('response body of a paused request'), with a clear qualifier ('at Response stage'). This distinguishes it from sibling tools like fetch_continue or fetch_fulfill, which modify or continue the request, and fetch_list_paused, which lists them.

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 implies it is used when a request is paused at the Response stage and you need its body. It does not explicitly exclude alternatives, but the context is clear, and no other tool names are needed. The 'at Response stage' qualifier provides clear usage context.

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