rate_release_in_user_collection

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

With no annotations, the description must disclose behavioral traits. It only says 'rate' but does not specify whether this creates a new rating, updates an existing one, or overwrites. It does not mention authentication requirements, side effects (e.g., changing collection value), or error conditions. The safety profile is unclear.

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 very short at two sentences, which is concise. However, the conciseness sacrifices necessary detail. It is not front-loaded with critical usage instructions. The structure is adequate but minimal.

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 the tool has 5 parameters, no output schema, and no annotations, the description is extremely incomplete. It fails to explain the relationship between parameters, expected outcomes, or potential errors. For a mutation tool, this is insufficient for an agent to use correctly.

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%, so the description should add meaning to parameters. It only reiterates that folder_id must be non-zero, which is already in the schema. There is no explanation of instance_id, the meaning of rating (1-5 scale?), or the role of username and release_id. The agent gets no additional semantic help.

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 that the tool rates a release in a user's collection, which is a specific verb+resource. However, it does not differentiate from sibling tools like 'edit_release_rating', which likely does the same action. The added note about folder_id being non-zero is redundant with schema constraints.

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 guidance is provided on when to use this tool versus alternatives such as 'edit_release_rating' or 'delete_release_rating'. There is no context about prerequisites like the user having the release in their collection, or when not to use it. The agent is left to infer usage from the name alone.

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