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

With no annotations provided, the description carries the full burden. It discloses key behavioral traits: it returns progress and result URLs when complete, and requires PIXELPANDA_API_TOKEN for authentication. This covers output behavior and auth needs, though it omits details like rate limits or error handling.

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 front-loaded with the core purpose in the first sentence, followed by essential details in a concise manner. Every sentence adds value: the first explains the tool's function, the second covers output behavior, and the third specifies auth requirements, with no wasted words.

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 the tool's low complexity (1 parameter) and the presence of an output schema (which handles return values), the description is complete enough. It covers purpose, output behavior, and auth requirements, addressing key aspects without needing to detail parameters or return values explicitly.

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 has 1 parameter with 0% description coverage, so the description must compensate. It does not explicitly mention the 'job_id' parameter, but implies its necessity by referring to 'an AI generation job'. This adds some semantic context, though it could be more direct. Since there are 0 parameters with schema descriptions, the baseline is 4, and the description meets this by providing relevant context.

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 the verb ('Check') and resource ('status of an AI generation job'), specifying what the tool does. It distinguishes itself from siblings like 'list_jobs' (which lists jobs) and other image processing tools by focusing on status checking for a specific job.

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 usage when needing to monitor job progress or retrieve results, but does not explicitly state when to use this tool versus alternatives like 'list_jobs' or other job-related tools. It provides clear context for checking status, but lacks explicit exclusions or named alternatives.

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