List live conferences

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so safety is covered. The description adds genuine behavioral scope beyond that: only names are returned, and only rooms currently running as opposed to all rooms ever created. It stops short of noting pagination or ordering, so it is not a 5.

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?

Two sentences, front-loaded with the operation and its endpoint, and every clause points somewhere useful. The trailing record-keeping advice is slightly instructional filler, which keeps it out of the top band.

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 zero-parameter read-only list with no output schema, the description covers what is returned (room names) and what to do next, which is enough to invoke it correctly. It does not mention result ordering, pagination, or failure modes, so a little is missing.

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 tool takes zero parameters and the schema is empty, so there is nothing for the description to disambiguate; the baseline for a no-parameter tool is 4. No parameter claims are made or needed.

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?

States a specific verb (List) plus resource (conference rooms) plus scope (currently running on this Vobiz account), even citing the underlying endpoint GET /Conference/. That is enough to separate it from list_live_calls and the single-conference get_conference without opening any schema.

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?

Explicitly routes the agent: use it to find a room before inspecting with get_conference or acting on members, and names end_conference as the follow-up. It gives clear positive usage context but never states a when-not condition (e.g., ended conferences or historical rooms are not returned).

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