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 multiple variants (Clean Upscale, Face Enhance, AI Restore, Full Restore), has a cost (1 credit), and requires authentication (PIXELPANDA_API_TOKEN). It does not mention rate limits, error handling, or processing time, but covers essential operational aspects.

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 appropriately sized and front-loaded: the first sentence states the core purpose, followed by key details (return variants, cost, parameters, auth). Every sentence adds value with no redundancy or fluff, making it efficient and easy to parse.

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 no annotations, 0% schema coverage, but an output schema exists, the description is fairly complete. It covers purpose, usage context, parameters, cost, and auth. However, it lacks details on error cases, input constraints (e.g., image size/format), and output structure, though the output schema may handle the latter.

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%, so the description must compensate. It explains the two parameters: 'image_url (public URL)' and 'file_path (local file)', clarifying their purpose and that either can be provided. This adds meaningful semantics beyond the bare schema, though it doesn't detail format constraints or examples.

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 'enhance, sharpen, and restore' with the resource 'image' and specifies the use of 'multiple AI methods'. It distinguishes from siblings like 'upscale_image' or 'adjust_image' by mentioning specific enhancement methods (Clean Upscale, Face Enhance, AI Restore, Full Restore).

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 provides clear context for when to use this tool (to enhance images with AI methods) and mentions cost (1 credit) and authentication (requires PIXELPANDA_API_TOKEN). However, it does not explicitly state when NOT to use it or name specific alternatives among the many sibling tools (e.g., vs. 'upscale_image' or 'adjust_image').

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