Schedule Zero Meeting Bot

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

Annotations indicate this is a mutating, non-idempotent operation, so the description does not need to restate that. However, it adds little about real-world effects: whether it creates a calendar event, sends invitations, starts the bot, or otherwise affects external systems. The 'signed-in user's' scoping is helpful, but the behavioral surface remains largely undisclosed.

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 concise sentences with no filler. The action comes first, and the critical usage precondition is second. Every sentence earns its place.

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?

With five optional parameters, no output schema, no parameter-level documentation, and an operation that mutates state, the description is not sufficient for an agent to confidently construct a correct call. It lacks details on which parameters are needed for which providers, how join_at and duration_minutes must be supplied, and what a successful result looks like.

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 description coverage is 0%, so the description must compensate for the five undocumented parameters. It only hints at two of them ('link or provider' maps to meeting_url and provider), leaving title, join_at, and duration_minutes unexplained. There is no guidance on formats, defaults, or how the parameters relate to scheduling 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 names a specific verb and resource: 'Schedule the signed-in user's Zero meeting bot for a link or provider.' This clearly identifies the action and target, and the 'for a link or provider' clause hints at the meeting URL/provider parameters. It does not explicitly contrast with sibling tools, but no sibling directly overlaps with scheduling this bot.

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 gives an explicit precondition: 'Call only after the user explicitly asks to schedule the bot.' This tells the agent when the tool is appropriate. It does not name alternative tools or say when not to use it, but the explicit trigger condition is strong enough guidance for this context.

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