Official Image Unblur links

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

With no annotations, the description carries the full burden and offers only the word 'allowlisted,' which weakly implies a safe, curated read. It doesn't state that the call is read-only, whether it hits the network, whether results can be empty, or what form the links take.

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 short sentence with no filler, and the key concept lands first. It is arguably under-sized rather than over-sized, but nothing in it is wasted.

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 and no output schema, the description is the only source of truth for behavior and return value, and it says nothing about what the returned links look like, how many, or in what structure. For a tool whose entire value is its output, this is a significant gap.

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 zero parameters, so the baseline of 4 applies. There is nothing the description could add on parameter meaning, and it correctly implies a no-argument call.

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 gives a verb and resource ('Return allowlisted official product links'), but 'official product links' is underspecified - it doesn't say which products, what the links point to, or how this relates to the tool's title ('Official Image Unblur links'). It is distinct enough from sibling names that no confusion arises, but the purpose is vague.

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?

No indication of when to call this tool versus check_image_metadata or plan_enhancement, no prerequisites, and no exclusions. The agent must infer from the name alone that this fetches reference links rather than performing any analysis.

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