Start a meeting (the bot joins and transcribes)

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

With no annotations, the description carries the full behavioral burden. It usefully discloses the visible side effects (participants see a robot badge and a transcribing chip) and that the bot is headless, but says nothing about idempotency, permissions, failure modes, or what happens on a meeting already in progress.

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 tight sentences with the action front-loaded and the prerequisite/observable effects following. No filler; the UI-detail sentence earns its place by describing visible behavior.

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?

There is no output schema, so return values need not be explained, but as a state-changing start operation with no annotations the description should say more about re-invocation behavior, error conditions, or required permissions. Adequate but with a clear gap.

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 single meeting_id parameter is fully documented in the schema, including its origin. The description adds no parameter-level detail beyond what the schema already states, so the baseline of 3 applies.

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 concrete action: the headless Meeting Bot joins the meeting and begins transcribing. It implicitly distinguishes itself from create_meeting by naming it as the prerequisite and from join_meeting by specifying that a bot (not a user) joins, though it never names join_meeting directly as the alternative.

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 prerequisite is clear — the meeting must already exist via create_meeting. However, there is no explicit guidance on when to choose this over join_meeting, nor what happens if the bot is already in the meeting or the meeting has ended; usage is implied rather than stated.

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