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

With no annotations, the description carries the behavioral burden. It usefully declares that the operation is read-only and specifies the default and maximum date ranges, but it omits whether a Google Meet connection is required, whether results are paginated, and what happens if the range exceeds 62 days.

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?

The description is a single compact sentence with the key scope and constraints front-loaded. The parenthetical range details and the dash-separated return-field list are efficient and contain no filler.

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 read-only list tool, it covers the core scope, date constraints, and returned fields in the absence of an output schema. It still leaves the agent_id parameter unexplained and does not state whether a Google Meet integration must be connected, which are meaningful gaps given there are no annotations.

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 coverage is 67%: start and end are described as ISO date/time, while agent_id is undocumented. The description adds meaningful range defaults and limits beyond the schema, but it does not explain that agent_id filters to a specific agent, and “all your agents” may even obscure that optional filtering behavior.

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 gives a specific verb and resource (lists Google Meet meetings) with scope (all agents), date-range behavior, and returned fields. It is clear what the tool does, but it does not explicitly distinguish itself from nearby siblings like list_google_meet_meetings or list_google_meet_history.

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?

It states the default range (next 7 days) and the maximum range (62 days), which gives useful usage context. However, it does not say when to choose this tool over list_google_meet_meetings, list_google_meet_history, or get_meeting, nor does it describe prerequisites such as needing Google Meet connected.

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