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

Annotations already declare destructiveHint=true, openWorldHint=true, and idempotentHint=false, but the description adds material context the agent could not derive: fixed two-week lifetime, irrevocability ('cannot be withdrawn before it expires'), and anonymous access. It does not say whether re-calling for the same meeting mints a second link or supersedes the first, which matters given non-idempotency, so it stops short of a 5.

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 short sentences, front-loaded with what gets created and its lifetime, then the permission gate, then the delivery constraint. Every sentence carries distinct information with 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 one-parameter mutation with an output schema, an agent has what it needs: what the link exposes, how long it lives, that it is irreversible, when it may be called, and what to do with the result. Return value details are correctly omitted since an output schema exists.

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 100% and the meeting_id description already points to list_meetings/search_meetings, so the schema carries the load. The description only weakly reinforces that it is a single meeting ('one meeting's summary'), adding no format or sourcing detail beyond the schema. Baseline 3 is appropriate.

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+resource with precise scope: creates a no-sign-in link exposing one meeting's summary and transcript, expiring in two weeks. That is distinguishable from every sibling (get_meeting, update_meeting, fetch) without opening any schema.

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 gating condition ('Call it only when the user asked to share this meeting') and a delivery rule ('give the link to the user rather than sending it anywhere yourself'), which prevents the agent from auto-emailing or proactively sharing. Nothing here is left to inference.

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