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

Annotations already disclose readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so safety is covered. The description adds useful behavioral context by saying it returns summaries rather than full payloads, but it does not describe pagination, result ordering, or any rate/auth constraints.

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?

Two concise sentences, front-loaded with the core purpose and followed by the key differentiation from get_template. Every clause contributes useful information.

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 read-only list tool with annotations and no output schema, the description is nearly sufficient: it explains that results are summaries and points to get_template for full payloads. It could be slightly more complete by mentioning pagination or the summary fields, but the core invocation guidance is present.

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 60%, with limit, query, and offset documented in the schema. The description mentions media categories generally but does not explain the category parameter or clarify that media_kind supports voice as well as image, video, music, and motion, so it adds only limited meaning beyond the schema.

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 states a specific action and resource: browsing the public template library, with examples of what a template contains (model + prompt + settings recipes). It explicitly distinguishes itself from get_template, so an agent can tell the two apart without inspecting schemas.

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?

It clearly positions this tool as the browsing/list-summary option and names get_template as the alternative for retrieving one template with its ready-to-run payload. It does not give explicit when-not guidance or mention search/filter behavior beyond the schema, so it is strong but not complete.

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