create_sync_ratings

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

Annotations already indicate a mutating, non-destructive, idempotent operation, and 'Add new ratings' is consistent with them. The description adds the endpoint and the schema-discovery instruction, but does not explain side effects, auth requirements, or response behavior beyond what annotations imply.

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 compact and front-loaded: action, endpoint, and argument guidance are each stated in a short line with no filler. Every sentence earns its place.

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 open-world body, the presence of an output schema, and annotations covering safety/idempotency, the description provides the key missing information: how to discover the expected body fields. It could say more about the semantics of ratings, but it is adequate for correct invocation.

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 schema only defines body as an open object, so the description's direction to 'Read the matching GET or the /schema endpoint first' is the main semantic contribution. It compensates for the 0% schema coverage by pointing the agent to an authoritative source, though it does not enumerate actual fields.

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 clear action and resource: 'Add new ratings,' reinforced by the explicit POST /sync/ratings endpoint. It is distinguishable from sibling operations like create_sync_ratings_remove and get_sync_ratings_by_type_by_rating, though it does not name alternatives.

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: use this tool to add new ratings. The instruction to read the matching GET or /schema endpoint first is helpful preparation, but the description does not explicitly state when to prefer this over related sync tools or when not to use it.

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