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

No annotations are provided, so the description carries the behavioral disclosure burden. It does reveal the rating threshold and 'top-rated' semantics, and 'Get' implies a read-only operation. However, it does not clarify whether the results are user-specific or global, how they are ordered, or whether authorization is required, leaving some behavioral ambiguity.

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 two short sentences with the core behavior front-loaded before the use case. There is no filler, and every sentence contributes useful information for selecting and invoking the tool.

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 one-parameter read tool with no output schema, the description is mostly adequate: it names the result, the default behavior, and a use case. It is incomplete regarding result ordering, user-specific vs. global scope, and return shape, which matters because sibling tools like list_saved_vibes could overlap semantically.

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 only parameter, min_rating, is already fully described in the schema with its default and range. The description merely restates the default threshold ('rating >= 7 by default') and adds no extra meaning about how the parameter affects the results, so the baseline score of 3 applies.

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 ('Get'), a specific resource ('top-rated vibes'), and the default rating threshold ('rating >= 7 by default'), so an agent can tell what the tool returns. It does not explicitly distinguish this from related siblings like list_saved_vibes or get_vibe_feedback, so it stops short of a 5.

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 gives a clear intended use case: 'Use this to suggest vibes the user has enjoyed before.' This is actionable and sufficiently specific for selecting the tool in a recommendation context. It does not mention when-not-to-use it or point to alternatives, but the guidance is not merely implied.

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