xtalk_room_leave

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

With no annotations, the description carries full burden for behavioral disclosure. It only states 'Leave one room' without explaining what 'leave' entails (e.g., does it destroy state? require ownership? affect others?). The lack of detail leaves the agent uncertain about side effects or constraints.

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 very concise at one sentence with no wasted words. However, it is so minimal that it could be considered under-specified rather than optimally concise. It earns a 4 for being short, but not a 5 because it lacks useful structure or additional context.

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 simple tool with one parameter and no output schema, the description should at least clarify behavioral context (e.g., 'Leaves the current room if no room specified'). It does not explain default behavior (the description says 'defaults to active room' in schema but not in description), nor does it mention prerequisites or effects. This leaves gaps for the agent.

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% (the only parameter 'room' has a description). The tool description does not add any new information beyond the schema, so baseline 3 is appropriate. The parameter is adequately documented in the 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 'Leave one room' clearly states the verb (leave) and resource (one room), making the purpose immediately understandable. However, it does not differentiate from sibling tools like 'xtalk_leave' which might have a similar function, losing a point for lack of distinction.

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?

No guidance is provided on when to use this tool versus alternatives (e.g., xtalk_leave, xtalk_room_use). The agent receives no context about prerequisites, such as needing to be in the room first, or whether leaving has side effects like disconnecting.

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