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

No annotations are provided, so the description carries the full behavioral burden. It usefully discloses partial-update semantics and the slides dependency for presentation mode, plus that the operation is free, but it omits prerequisites such as needing Google Meet connected and does not describe permissions or error behavior.

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 very short and every phrase corresponds to a setting or behavior, with no filler. It is telegraphic rather than fully structured, which slightly reduces readability but keeps it appropriately concise.

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 six-parameter mutation tool with no annotations and no output schema, the description covers the updated fields and partial-update behavior. However, it leaves out important operational context such as whether Google Meet must already be connected and what the caller should expect on success or failure.

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%, with descriptions for id, language, meeting_mode, and join_before_minutes. The tool description adds meaning by mapping the remaining settings and clarifying that presentation mode needs slides, which is useful context beyond the schema's enum label.

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 settings that can be changed (auto-join, join timing, greeting, language, meeting mode) and the title/name identify it as an update operation. It is distinguishable from get_google_meet_settings and connect_google_meet, though the description itself does not explicitly say it updates an agent's Google Meet configuration.

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?

There is no explicit guidance about when to use this tool versus alternatives such as get_google_meet_settings or connect_google_meet. The phrase "Only what you pass changes" explains partial-update behavior but does not provide when/when-not usage guidance.

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