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

Annotations already flag destructiveHint=true, and the description adds real context beyond them: irreversibility ('Cannot be undone'), the cascading deletion of the in-use photo and angles, and the first-call-returns-token workflow. That is exactly the behavioral detail an agent needs before invoking a destructive operation.

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?

Three compact sentences, front-loaded with the action and scope, then the irreversibility warning, then the confirmation mechanic. No filler and no repetition.

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 destructive, no-output-schema tool, the description covers destruction scope, irreversibility, and the token workflow, which is most of what is needed. It could note that the confirmation summary precedes actual deletion of all listed assets, but the gap is minor.

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 coverage is 67%, so confirmToken and site are already documented in the schema; the description's confirmToken mention largely repeats the schema text. photoId carries no description in either place, and the description adds no format or constraint detail, so a baseline 3 is appropriate.

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?

States a specific verb and resource ('Removes a product photo ... from the bank') and clarifies the cascading scope (in-use photo and angles), which distinguishes it from generic delete_* siblings. It stops short of naming an alternative such as duplicate_photo or restore_photo_original, so sibling differentiation is only partial.

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 explains the two-step confirmation flow ('call again with confirmToken to proceed'), which is genuine usage guidance, but it never states when to prefer this over relatives like delete_product or update_photo, nor when not to use it. Usage is implied rather than explicitly routed.

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