Get one meeting with attendee answers

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

Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, so safety is covered structurally. The description still adds non-obvious behavior: attendee answers (accepted/declined/tentative) arrive automatically from participants' calendars rather than being set here. The closing 'changes nothing' is largely redundant with readOnlyHint.

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 purpose and return contents, then the id-procurement hint. Nearly every clause earns its place, though 'changes nothing' duplicates the readOnly annotation.

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 no output schema, the description compensates by enumerating the returned payload (times in UTC and local, place, attendees and answers), and it explains how to obtain the required id. Nothing an agent needs to invoke it correctly is missing.

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 and schema description coverage is 100%, so the schema already documents the id fully (including its origin). The description restates that origin ('Use list_events to find an id') without adding format, validation, or error semantics, which is the expected baseline when the schema does the work.

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 (get) and resource (one meeting), then enumerates the returned fields: title, UTC/local times, place, attendees and their answer states. It explicitly ties the resource to create_event and names list_events as the id source, so an agent can distinguish it from the sibling list_events and update_event.

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 clear operational context: the event must have been created with create_event, and list_events is the way to obtain an id. It does not spell out when to prefer this over a hypothetical alternative for a single event, but for a one-id read tool the guidance is effectively complete.

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