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

With no annotations provided, the description carries the full burden for behavioral disclosure. It mentions search and pagination but does not describe response format, cursor-based pagination mechanics, authentication via apiKey, or any side effects, leaving significant behavioral traits undisclosed.

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, front-loaded sentence that efficiently conveys the core function and key features. There is no filler or redundant information, making it appropriately concise and well-structured.

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 7 parameters and no annotations or output schema, the description is too brief to cover essential context such as the required orgSlug, pagination mechanics, and authentication. It provides only a high-level overview, which is insufficient for an agent to invoke the tool reliably across varied scenarios.

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 input schema has no descriptions for any of the 7 parameters, so the description must compensate. It explains that 'provider' and 'outstanding debt' are filters, but it does not explain the semantics of apiKey, cursor, limit, or orgSlug, leaving a substantial gap in parameter understanding.

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 that the tool lists clients of an organization and mentions search, pagination, and filters. It uses a specific verb 'List' and specifies the resource 'clients', but it does not explicitly distinguish itself from sibling tools like client_get or cierre_listar_clientes, so it lacks sibling differentiation.

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 description provides no guidance on when to use this tool versus alternatives. It does not mention any exclusions, prerequisites, or conditions that would help an agent decide between this and other client-related tools, leaving usage entirely implied by the tool name.

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