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

The description openly states the destructive nature by saying 'Delete,' and the annotations confirm destructiveHint: true. It does not add details about side effects or permanence, but given the annotation coverage, the bar is met without contradiction.

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 short, but the guidance portion is redundant, repeating 'Delete one CMS photo gallery item by photo id.' The cryptic 'context: id' suffix adds clutter without clear value. It could be more streamlined.

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 delete operation, the description provides enough context: what it deletes (photo gallery item) and how to specify it (by photo id). It does not mention error conditions or prerequisites, but these are not essential for a straightforward delete tool, especially with the sibling list disambiguating scope.

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 already fully describes the 'id' parameter as 'Photo item id returned by cms_list_photos,' so schema coverage is 100%. The description does not add further meaning beyond that, aligning with the baseline for high schema coverage.

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 and target: 'Delete photo' and 'Delete one CMS photo gallery item by photo id.' It specifies the resource type (photo gallery item) and the scope (by photo id), distinguishing it from other delete tools in the sibling list.

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 provides no explicit guidance on when to use this tool versus alternatives, such as other delete or update tools. It only restates the action, with no prerequisites or conditions for use.

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