xtalk_room_use

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

With no annotations, the description must disclose all behavioral traits. It only reveals that other rooms are not left, but fails to clarify what 'set active room' means, side effects (e.g., on reading/broadcasting), authorization needs, or whether it is a mutating operation.

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 extremely concise - a single sentence with no wasted words. However, it may be overly sparse given the lack of annotations and schema descriptions.

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 tool with one basic parameter and no output schema, the description should explain the concept of 'active room', how it interacts with other tools (e.g., xtalk_read), and any limitations. It currently leaves critical context gaps.

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 parameter 'room' has no schema description (0% coverage), and the description adds no meaning beyond the parameter name. The agent receives no guidance on format, allowed values, or constraints for this string parameter.

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 'Set' with a clear resource 'active room' and includes a distinguishing behavior 'without leaving other rooms,' which differentiates it from sibling tools like xtalk_room_join and xtalk_room_leave.

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 implies a use case (switching active room while staying in others) but does not explicitly state when to use versus alternatives, nor does it provide when-not-to-use scenarios or prerequisites.

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