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

With no annotations provided, the description must carry the full burden. It usefully discloses the read-only (non-mutating) nature and the Google Meet connection prerequisite, but says nothing about pagination, filtering, rate limits, or the shape of the returned meetings.

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 compact sentences that front-load the read-only nature before the prerequisite, with no wasted wording. Size is appropriate for a simple list tool.

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 simple list tool this is nearly adequate, but with no annotations, no output schema, and an entirely undocumented required 'id' parameter, the description leaves an agent without what it needs to call the tool correctly.

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?

There is one required parameter 'id' with 0% schema description coverage, and the description never explains what it is (agent id? workspace id?) or how it scopes the result. The description does not compensate for the schema gap, leaving the required parameter undocumented everywhere.

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 a specific verb and resource ('Read-only list of meetings the agent has scheduled'), and the title adds that these are Google Meet meetings booked by this agent. It is easily distinguishable from the connect/disconnect Google Meet siblings, though it does not explicitly name them.

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 description implies when to use it (to view meetings this agent booked) and states a precondition ('Requires Google Meet connected first'), but gives no explicit when-not guidance or alternatives to compare against. Usage is largely left to inference.

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