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

With no annotations present, the description's 'Read-only' tag does real work by declaring a non-mutating operation. It also enumerates the response payload, which compensates for the absent output schema. It does not say what happens when Meet is not connected (e.g., whether an error is thrown or a connected=false flag returned) or whether any permission scoping applies.

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, with the payload contents front-loaded before the read-only qualifier. The first sentence is a fragment ('Whether Google Meet is connected ... and totals') but is efficient and free of padding.

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 one-parameter read with no output schema, enumerating the returned fields (connection status, invite address, settings, totals) gives an agent enough to know what it will get back. The only meaningful gap is the not-connected case, which is a minor omission for a simple status tool.

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 a single required parameter 'id' with 100% schema description coverage, and the schema already documents it as an agent UUID sourced from list_agents. The description adds nothing about the identifier, so baseline 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?

The description names the resource (Google Meet connection for a given agent) and enumerates the returned content: connection status, invite address, settings, and totals. It is clearly a read of the agent's Meet configuration, distinguishable from 'update_google_meet_settings' by the stated read-only nature. No sibling is named explicitly, so it falls short of a 5.

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?

'Read-only' implies this is the call for inspecting rather than changing Meet settings, which implicitly contrasts with update_google_meet_settings and connect_google_meet, but the description never states when to choose this over those siblings. No prerequisite or exclusion is given.

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