delete_photo

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

With no annotations, the description carries the full burden of behavioral disclosure. It merely states 'delete', which implies destructiveness, but does not disclose permanence, effects on related data, permission requirements, or return behavior. This is inadequate for 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?

The description is a single, direct sentence that is front-loaded and free of any padding. It is appropriately compact for a simple delete-by-ID tool.

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 the destructive nature and absence of annotations and output schema, the description should explain what end-user impact deletion has, whether it is reversible, and what the response looks like. It only covers the action and the parameter, leaving critical operational details missing.

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 schema has one required integer 'id' with 0% description coverage. The phrase 'by ID' adds minimal semantic meaning (the id is the photo identifier), but does not clarify how to obtain the ID, any constraints, or what the integer represents beyond the parameter name. It fails to compensate for the lack of schema documentation.

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 action (Delete), the resource (Photo), and the identifier (by ID). It is specific and distinguishes itself from siblings like get_photo, update_photo, or list_photos.

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 guidance is given on when to use this tool versus alternatives, nor any exclusions or prerequisites. The description only implies its use for deleting a photo by ID, which is insufficient for choosing among similar delete tools.

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