retell_update_chat_agent

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

No annotations are provided, so the description must fully convey behavioral traits. It only says 'update configuration,' which is generic and does not explain whether the update is partial or full, what fields are affected, or what the response includes. Side effects and requirements are not disclosed.

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, grammatically compact sentence that immediately states the tool's purpose. It contains no redundant or overly technical language and is easy to parse at a glance.

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?

With seven parameters, no annotations, and no output schema, a one-line description is insufficient. It does not explain update semantics (merge vs. replace), the effect of omitting optional parameters, or expected return value. This leaves significant gaps for an agent invoking the tool correctly.

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 schema already provides descriptions for all seven parameters, achieving 100% schema description coverage. The tool description adds no additional parameter-level context, so it neither helps nor hurts beyond the schema. A baseline of 3 is appropriate given the 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 clearly states the action ('Update') and the specific resource ('existing chat agent'), and the qualifier 'configuration' distinguishes it from create/delete operations. Sibling tools include both retell_update_agent and retell_update_chat_agent, so naming 'chat agent' explicitly eliminates ambiguity.

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_update_agent or retell_update_call. No usage scenarios, prerequisites, or exclusions are mentioned, leaving the agent to infer usage solely from the tool name.

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