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

With no annotations, the description carries the full burden and discloses the key non-obvious behavior: scheduled meetings are NOT cancelled, and the call must follow a preview plus user approval. It stops short of stating idempotency, whether reconnecting restores prior settings, or permission requirements, so it is strong but not exhaustive.

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?

Three tight sentences, front-loaded with the core action, then the non-obvious non-effect, then the required sequence. Every sentence earns its place and nothing is redundant.

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 mutation with no output schema, the description covers the action, scope of destruction, and required approval workflow. It would be complete at 5 with a note on reversibility (e.g. reconnect via connect_google_meet) or whether prior auto-join settings are retained.

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?

Only one parameter ('id'), fully documented in the schema with its provenance ('from list_agents'). The description adds no additional meaning about the parameter, so the baseline of 3 for complete schema coverage 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 specific verb and resource ('Remove the Google Meet channel from the agent') plus the side effect ('turn auto-join off'), which distinguishes it from connect_google_meet and get/update_google_meet_settings. It also explicitly contrasts with cancel_meeting, so an agent can route correctly without opening schemas.

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 an explicit precondition chain: run preview_disconnect_google_meet first and obtain user approval. It also names the alternative (cancel_meeting) for the adjacent need of cancelling already-scheduled meetings, covering both when-to-use and when-to-use-something-else.

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