Check extract job status

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

The annotations already indicate a safe, idempotent read operation. The description adds the behavioral detail that the tool returns status immediately and, upon completion, includes a per-URL results array, which is useful for understanding polling behavior. No contradiction with annotations.

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 outcome with no extraneous text. It earns a top score.

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?

Given that an output schema exists and the tool has a single parameter, the description adequately covers the tool's purpose, return behavior, and usage context. It is complete for the tool's complexity.

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 input schema already defines 'id' as the extract job id from crw_extract, and the description does not add any additional parameter semantics. With 100% schema coverage, the baseline of 3 applies.

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 the specific verb 'Poll' and identifies the resource as 'an extract job,' clearly distinguishing it from the similar sibling 'crw_check_crawl_status' by specifying 'extract' and the per-URL results array. It states exactly what the tool does and its output.

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 clearly implies usage when checking the status of a previously submitted extract job, providing clear context. However, it does not explicitly mention alternatives or when not to use this tool, such as for crawl jobs, so it lacks explicit exclusions.

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