retell_list_chat_agents

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

No annotations are present, so the description carries the full burden. It clearly indicates a read-only operation that returns all chat agents, but it does not disclose pagination, response format, or whether only active agents are included. The scope is clarified, yet operational details are missing for a tool with no other behavioral metadata.

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, concise sentence that clearly states the action and resource. It is front-loaded and contains no filler or redundant information, making it a model of brevity.

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?

The tool is simple (no parameters, no output schema), and the description communicates the core scope. However, it does not specify the return payload structure or any handling of large result sets. While adequate for a trivial list operation, it leaves the agent to infer the response shape.

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?

There are zero parameters, so the schema is empty. The baseline is 4, and the description correctly remains silent on parameters. No additional semantic value is needed since no inputs exist.

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 uses the specific verb 'List' and the resource 'chat (text/messaging) agents' with a clear scope ('in your Retell AI account'). It explicitly distinguishes this tool from sibling tools like retell_list_agents or retell_list_phone_numbers by specifying the agent type.

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 such as retell_list_agents. It does not mention whether retell_list_agents covers voice agents or when to prefer this specific listing. No exclusions or alternative suggestions are provided, leaving the agent to rely on the name alone.

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