end_conversation

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

With no annotations, the description carries the burden. It discloses two key behaviors: speaking a goodbye message and stopping the browser interface. While it doesn't mention reversibility or side effects, the terminal nature of ending a conversation is well conveyed.

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 sentence of 11 words, front-loaded with the main purpose and method. Every word earns its place with no filler or redundancy.

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 the tool's simplicity (one required parameter, no output schema), the description is adequately complete. It explains what the tool does, how it does it, and the parameter is documented in schema. Minor gap: no mention of prerequisites or post-conditions, but overall sufficient.

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 coverage is 100% with the parameter 'good_bye' already described as 'The goodbye message to speak before ending the conversation'. The description adds no additional semantic value beyond the schema, so a baseline 3 is appropriate.

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 has a specific verb and resource: 'End the voice conversation' with clear method 'by saying goodbye and stopping the browser interface'. It clearly distinguishes from siblings like speak, converse, and get_voice_input by indicating this is the termination action.

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?

Although no explicit alternatives are named, the description clearly implies this tool is for ending the conversation, which is contextually distinct from the sibling tools. The phrase 'End the voice conversation' directly indicates the when-to-use scenario, and the method gives additional guidance.

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