list-customers

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

Annotations already declare readOnlyHint=true, and the description reinforces this with the HTTP method GET. It adds the required 'customers:read' scope, which is an auth-relevant behavioral detail not present in the annotations.

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 communicates the operation, endpoint, and scope with zero filler. All information is immediately relevant and front-loaded.

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?

This is a low-complexity list operation: annotations cover the read-only behavior, the schema covers all parameters, and the description supplies endpoint and auth scope. Pagination defaults are already declared in the schema, so nothing critical is missing.

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 for the three parameters is 100%, so the schema already documents q, page, and itemsPerPage. The description adds no extra semantics or format details beyond that baseline coverage.

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 specific verb ('List') and resource ('customers'), and pins it to the exact endpoint (GET /api/public/customers). This clearly differentiates it from sibling tools like list-customer-contacts and list-crm-leads, whose resources are distinct.

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 choose this tool over alternatives such as list-customer-contacts or list-crm-leads. The description only states the endpoint and scope, leaving usage context entirely to inference.

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