retell_update_conversation_flow

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

With no annotations, the description must disclose behavioral traits. It only states 'Update,' implying mutation, but provides no details about whether the update overwrites the entire flow, whether omitted fields are preserved, what data structure nodes must follow, or any side effects or prerequisites. This is a significant gap for a mutation tool with a complex schema.

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 with no filler words. It immediately states the action and resource, making it efficiently scannable. Every word contributes to the core message, though the content could be richer.

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 9-parameter, nested-object mutation tool with no annotations and no output schema, a one-sentence description is inadequate. It does not explain update semantics (full vs partial), return values, or operational context. The schema provides param-level details but not the behavioral context needed to use 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?

Schema description coverage is 100%, so each parameter is documented in the schema. The description adds little beyond listing a few updatable fields (nodes, model, prompt, tools) but omits others and introduces 'edges' without a corresponding parameter. It does not clarify parameter relationships or required combinations, so it neither adds significant value nor detracts from the already sufficient 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?

The description uses the specific verb 'Update' and identifies the resource as an 'existing Conversation Flow,' clearly distinguishing it from create and delete siblings. It lists updatable aspects (nodes, edges, model, prompt, tools), though it omits some schema parameters (start_node_id, start_speaker, knowledge_base_ids, default_dynamic_variables) and includes 'edges' which is not an explicit parameter, causing slight ambiguity. Still, the core purpose is unmistakable.

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 'existing Conversation Flow' implies the tool is for flows that already exist, providing basic usage context. However, it does not name alternatives such as create_conversation_flow for new flows or update_conversation_flow_component for component-level updates, nor does it state when not to use it. Guidance is only implied by the name and resource type.

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