get_release_rating_by_user

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

No annotations are provided, so the description carries full burden. It implies read-only but does not state it explicitly. Lacks information about behavior when user has not rated, authentication requirements, rate limits, or data freshness. The description only states what the tool does, not its behavioral traits.

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 a single, concise sentence with no extraneous words. It is appropriately front-loaded with the verb. However, it is too brief to earn a 5, as it omits useful information that could be added without bloating.

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?

Given no output schema, no annotations, and 2 simple parameters, the description is minimally adequate but incomplete. It does not explain the return structure (e.g., rating value, null handling) or provide any usage context. More detail is expected for full completeness.

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 0%, so the description must compensate. It mentions 'for a given user' (username) and 'release's rating' (release_id) implicitly, but does not describe formatting, constraints, or case sensitivity. The information adds minimal value beyond the parameter names.

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 it retrieves a release's rating for a specific user, using a specific verb ('Retrieves') and resource ('release's rating'). It distinguishes this from siblings like 'get_release_community_rating' (which gets community rating) and 'rate_release_in_user_collection' (which writes a rating).

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 does not mention when not to use it (e.g., if community rating is needed) or any prerequisites (e.g., user must have rated). No explicit context for selection among similar tools.

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