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

Annotations already establish that this is a read-only, non-destructive operation. The description adds that it is a GET endpoint under /api/Clients/{id}/Addresses, but it does not discuss authentication, pagination, empty results, or the shape of the returned addresses.

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?

Two short sentences with no waste. The core purpose and the key return-value caveat are front-loaded, followed by the endpoint for completeness.

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 simple one-parameter read operation with annotations covering safety, the description is nearly complete: it says what is returned and why the ids matter. It stops short of describing the returned address fields or whether multiple addresses are expected, which would help since no output schema exists.

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 100%, so the single client_id parameter is already documented in the schema. The description adds only the path template GET /api/Clients/{id}/Addresses, which confirms the parameter's role but does not add meaningful detail beyond the schema.

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?

States a specific resource (addresses of a customer) and adds useful semantic context: the ids are what an order needs as address_id. It is clear what it does, but it does not explicitly distinguish itself from siblings such as binderp_get_client or binderp_list_clients.

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 phrase 'the ids that an order needs as address_id' signals the practical use case: retrieving address identifiers before creating an order. However, it does not explicitly state when not to use it or name an alternative for related lookups.

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