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

Annotations already declare destructiveHint=true, idempotentHint=true and readOnlyHint=false, so the safety profile is covered structurally. The description contributes the user-visible effect (image disappears from the chatbot), but says nothing about permanence, whether the delete is reversible, or what happens if the image is referenced elsewhere.

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, front-loaded with the action and its consequence, with no filler or redundancy.

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?

For a single-parameter destructive tool whose annotations cover the safety profile and which has no output schema, the description is minimally sufficient to select and invoke it. It is thin on the consequences of an irreversible delete (referencing pages, caches, or audit implications), which would matter to an agent deciding whether to call it.

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?

With one parameter and 100% schema description coverage, the schema already documents image_id and points to list_images as its source. The description adds no format, range, or sourcing detail beyond that, so the baseline 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 gives a specific verb ('Remove') and resource ('one image'), and adds the observable consequence that the chatbot stops showing it. It is unambiguous against siblings like list_images or delete_product, though it does not explicitly name an alternative operation to contrast with.

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 when-to-use or when-not-to-use guidance, no stated prerequisites or permission requirements, and no named alternative (e.g., reuse list_images to find the id, or a hypothetical hide/deactivate option). The only usage hint is indirect, via the schema's note that the id comes from list_images.

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