xtalk_register

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

With no annotations, the description carries full burden but only states 'register' and 'join'. It does not disclose whether the tool creates a new agent, modifies state, requires authentication, or has side effects beyond joining a room.

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 brief (one sentence), but it lacks structure and fails to convey essential information. It is under-specified rather than appropriately concise for a tool with 5 parameters.

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 has 5 parameters, 0% schema coverage, no output schema, and no annotations, the description is grossly incomplete. It does not explain how to use the parameters, what the tool returns, or how it fits into the broader context of workspace rooms.

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 0%, yet the description adds no meaning to any of the 5 parameters (alias, client, workspace, capabilities, workspace_room). The description fails to explain what each parameter does or how they relate to registration and joining.

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 specific verb 'register' and resource 'agent' and mentions joining a workspace room. It clearly indicates the tool's function, but does not distinguish from sibling tools like xtalk_room_join which also involves joining a room.

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_room_join, xtalk_room_create). There is no mention of prerequisites, context, or exclusions.

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