Get a live conference

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

Annotations already cover the safety profile (readOnlyHint=true, openWorldHint=true), so the bar is lower, and the description still adds real context: it constrains the lookup to a 'running' conference and itemizes the response payload, which matters since no output schema exists. It does not mention failure behavior for a non-existent or ended conference.

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, no filler, with the retrieval action and endpoint front-loaded and the workflow guidance second. Every clause carries information.

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 single-parameter read tool with no output schema, the description adequately covers what is returned and how the result is consumed downstream. Only minor gaps remain around error/empty-result behavior.

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 100%, and the schema already states the name must match the <Conference> XML element exactly. The description adds only the phrase 'by name,' so the baseline 3 is appropriate.

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 and resource ('Get one running Vobiz conference room by name') with the underlying endpoint, and enumerates the returned fields (run time, member count, member_id, call_uuid, caller, mute/deaf state). This clearly distinguishes it from the sibling list_conferences, which enumerates rather than retrieves a single 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?

Gives a concrete downstream purpose: 'Use it to find the member_id values that the mute, deafen, kick, hang-up and play tools need,' naming the sibling tools that consume its output. It lacks an explicit when-not clause (e.g., use list_conferences to enumerate rooms), so it falls just short of a 5.

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