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

The description is consistent with annotations (destructiveHint=true) but adds no extra behavioral context beyond stating the delete operation. Since annotations already cover destructiveness, the description meets the baseline but does not go further.

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 brief and front-loaded, but contains slight redundancy between 'Delete sound item' and 'Delete one CMS sound item by sound id'. Still, it is well-structured and free of unnecessary content.

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 with one input and no output schema, the description is fully sufficient. No additional context about return values or complex behavior is needed.

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 provides a complete description for the 'id' parameter ('Sound item id returned by cms_list_sounds'). The tool description only repeats this information without adding new meaning, so baseline score of 3 applies given 100% 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 tool's function: deleting a CMS sound item by ID. It uses a specific verb ('Delete') and resource ('sound item'), and is distinct from sibling tools that handle paragraphs or other content types.

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 guidance on when to use this tool versus alternatives. It repeats the operation but does not mention boundary conditions (e.g., 'use this for sound items, not sound paragraphs') or recommend when deletion is appropriate.

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