service_order

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

Annotations already declare readOnlyHint=true and openWorldHint=true, covering the safety profile. The description adds useful return-content context (songs, keys, arrangements, lengths), but does not explain permissions, errors, or pagination.

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, compact sentence with no filler. Its weakness is under-specification rather than verbosity, but the phrasing is front-loaded and efficient.

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 read-only tool with two required parameters, 0% schema description coverage, and no output schema, the description does not do enough. It gives a rough sense of returned content but omits parameter meaning, usage context, and call prerequisites.

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 must carry parameter meaning. It implies plan_id via 'one of your plans' but does not explain service_type_id or the required relationship between the two parameters. Service_type_id is completely undocumented.

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 identifies the resource domain ('order of service for one of your plans: songs, keys, arrangements and lengths'), but it is a noun phrase with no explicit verb. An agent can infer it retrieves service order data, especially given readOnlyHint, but the action is not stated outright.

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?

There is no indication of when to use this tool versus alternatives, what prerequisites exist, or what conditions apply. The nearby sibling tools are largely unrelated, so the gap is less harmful, but the description offers no usage guidance.

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