B3.2/5.0
Behavior2/5

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

Annotations already declare destructiveHint=true and idempotentHint=true, but the description adds no behavioral context beyond that, such as whether the cover is permanently removed, whether a default cover is restored, or any side effects. The description does not contradict the annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is very short and front-loaded with the core action, then the endpoint, then parameter guidance. There is no filler or redundant content; every line serves a purpose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple delete operation with annotations covering destructiveness and idempotency, the minimal description is mostly adequate. However, it omits details about the effect of deletion and gives no usage context, and it relies heavily on the external GET/schema instruction for body construction.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With schema description coverage at 0%, the description compensates by labeling id as a path parameter and body as the request payload. The instruction to read the matching GET or /schema endpoint first is useful for discovering expected body fields, though the description does not explain what id represents or enumerate body fields.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb and resource: 'Delete items cover' and the endpoint DELETE /api/items/{id}/cover. It is specific enough to be distinguished from sibling delete operations like delete_items_by_id, though it does not elaborate on what 'cover' means or the scope of deletion.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

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 such as patch_items_by_id_cover or get_items_by_id_cover. The only usage-related instruction is to read the matching GET or /schema endpoint for body fields, which is about parameter construction rather than tool selection.

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