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

Annotations already declare readOnly, idempotent, non-destructive, closed-world behavior. The description adds that this is a compatibility alias, which is useful behavioral context, but it does not disclose return format, pagination, or alias semantics.

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 single sentence is short and front-loads the listing purpose, but it is under-specified rather than genuinely efficient; it omits information an agent needs to invoke the tool correctly.

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 four-parameter tool with no schema descriptions and no output schema, the description is too thin. Annotations cover safety, but the description does not compensate for missing parameter and return-value context.

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?

Schema description coverage is 0% for all four parameters. The description mentions 'by kind' and thus adds minimal meaning for the required kind parameter, but says nothing about limit, query, category, or the kind enum values.

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?

States a specific verb 'listing' and resource 'Watermelon entries' with the kind scoping, but 'Compatibility alias' is unexplained and it does not differentiate from siblings like get_catalog_entry or list_categories.

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 when-to-use, when-not-to-use, or alternatives are given. The phrase 'Compatibility alias' hints at a use case but does not say when an agent should choose it over search or get_catalog_entry.

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