Get Packed Images

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

No annotations are provided, so the description carries the full behavioral burden. It implies a read of existing output, but says nothing about what happens if the job_id is unknown, whether the images are returned as URLs, paths, or binary data, or how failure is surfaced.

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?

A single efficient sentence with the resource and target scope front-loaded. It is not padded, though it is arguably too terse to earn top marks.

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?

With no annotations, no output schema, and three parameters at 0% description coverage, the definition is under-specified: it does not explain the return shape (one image vs many, and in what form) or how limit/start_index paginate results.

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?

Schema description coverage is 0% and the description never mentions any of the three parameters. 'One or more' loosely gestures at limit, but limit, start_index, and their defaults/pagination semantics are entirely undocumented in both schema and description.

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 concrete verb ('Return') and resource ('packed PNG images'), plus the scope constraint that they are previously generated for a stored job. It is clearly distinguishable from compress_pdf and get_job_manifest, though it never names those siblings.

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?

There is no explicit when-to-use guidance, no prerequisites (e.g. a job must have completed), and no mention of alternatives or when not to call it. The phrase 'for a stored job' only weakly implies the usage context.

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