Create WebRTC Voice Session

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

Annotations already convey the safety profile (readOnlyHint=false, destructiveHint=false, idempotentHint=false), and the description is consistent with them ('Create' implies mutation). However, the description adds no additional behavioral context such as return payload, persistence semantics, authentication needs, or side effects beyond what annotations state.

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 sentence that front-loads the action and resource, with zero filler or redundancy. Every word contributes to understanding the tool's purpose.

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 (2 well-documented string params, annotations present), so a short description is mostly adequate. However, the absence of an output schema means the agent receives no hint about what a successful creation returns (e.g., connection details), and the description does not differentiate from the large set of sibling session tools beyond the WebRTC qualifier.

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%, with both agent_id and voice_id clearly documented. The description's mention of 'agent + voice id' merely restates the schema and adds no extra meaning, format, or usage details.

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 a specific verb ('Create') and names a distinct resource ('WebRTC voice session') along with the two key inputs (agent + voice id). The 'WebRTC voice' qualifier clearly distinguishes this from sibling session tools like lyzr_session_create, lyzr_session3_create, and lyzr_start_session.

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 offers no guidance on when to choose this tool over alternatives, no prerequisites, and no exclusions. It merely restates the action without contextualizing when a WebRTC voice session is the right choice versus sibling session/chat tools.

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