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

No annotations are provided, so the description carries the full behavioral burden. It does disclose the return fields (ids, names, technique, duration), which is genuinely useful, but it does not state that this is a non-mutating read, whether results are paginated or ordered, or how the query matching behaves (substring, fuzzy, tag prefix).

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 tight sentences: the purpose and searchable scope come first, the return shape second. No filler, no repetition of the title, and every clause carries 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 two-parameter, no-output-schema list tool, the description covers what is searched and what comes back, which is close to sufficient. It stops short of ordering/pagination behavior and total-result handling, which an agent might still wonder about.

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 coverage is only 50%: query is documented as 'Optional search text' but limit has no description in the schema. The description adds value by clarifying that the query matches name, prompt, or tag, but says nothing about the limit parameter's pagination semantics or the absence of a required argument.

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 (search) and resource (the user's sound library), and names the searchable fields (name, prompt, tag) plus the returned fields. This clearly separates it from siblings like generate_sound_effect, download_sound, and make_variations without requiring a schema read.

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?

Usage is implied by the name and purpose but never stated: there is no explicit when-to-use, no mention of when to prefer list_sounds over generate_sound_effect or download_sound, and no exclusions. An agent can infer this is a browse/search tool, but nothing is spelled out.

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