Delete an image

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

The description clearly indicates the destructive effect of removing an image, which aligns with the destructiveHint and readOnlyHint annotations. It does not mention idempotency or output, but the annotations already cover those aspects and the description adds the user-visible effect.

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, short sentence that states the action, target, and effect without any redundant words or unnecessary detail.

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 simple single-parameter destructive operation with no output schema, the description combined with annotations and parameter schema provides all the context needed to invoke the tool correctly.

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 fully describes the only parameter, image_id, and its source ('Image id from list_images'). With 100% schema coverage, the description adds no additional parameter detail, so a baseline score of 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?

The description uses a specific verb ('Remove') and names the resource ('one image') and the intended effect ('so the chatbot stops showing it'), which makes the tool's purpose unambiguous and distinct from sibling tools like add_image.

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 implies when to use the tool: when an image should no longer be shown by the chatbot. It does not explicitly contrast with alternatives, but the purpose is clear enough for an agent to select it appropriately.

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