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

Beyond the annotations' safety profile, the description usefully discloses the one-line-summary granularity and the two types of services listed. It does not clarify catalog completeness, returned identifiers, or how the listed services connect to subsequent tool calls.

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?

A single compact sentence front-loads the operation and then adds useful detail about output and service categories. There is no unnecessary wording.

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 zero-parameter read-only listing tool, this provides enough information to understand and invoke it successfully. Explicit next-step guidance and a note about whether identifiers needed by sibling tools are returned would make it more complete, especially without an output schema.

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 tool has no parameters, so there is no parameter behavior requiring explanation. The description appropriately focuses on the returned content instead.

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 the verb and resource—listing Bayline's services—and adds that each service has a one-line summary. The distinction between instant lookups and submittable requirements clarifies the catalog's contents, though the description does not explicitly differentiate this tool from describe_proposition.

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 wording implies that this is a discovery tool for browsing available lookups and requirements. However, it gives no explicit guidance on when to use it before describe_proposition or instead of submit_request.

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