xtalk_discover

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

No annotations are provided, so the description must disclose behavioral traits. It does not explain if the operation is read-only, requires authentication, or what happens with missing workspace/defaults. The workspace parameter lacks any description, leaving its role ambiguous.

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 concise sentence, but it is too terse to convey necessary details. It wastes no words but fails to utilize the space efficiently for completeness.

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 lack of annotations and output schema, the description should provide more context about return values, behavior when parameters are omitted, and typical use cases. It is insufficient for an agent to fully understand the tool's semantics.

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 50% (only 'room' described). The description adds no new parameter information; it does not explain 'workspace' or how parameters interact. The schema already describes 'room' defaults, but the description offers no additional semantics.

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?

Description states 'Discover members in a room or workspace.' This clearly identifies the action (discover) and resource (members). It distinguishes from siblings like xtalk_presence, though 'discover' could be more precise (e.g., 'List').

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 on when to use this tool over siblings like xtalk_presence or xtalk_room_list. No conditions, prerequisites, or exclusions are mentioned.

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