accept-calendar-event

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

The description adds a tip about silently accepting by setting sendResponse to false, but does not disclose other behavioral aspects such as modification of event status, requirement for organizer notification, or irrereversibility. Annotations already indicate destructiveHint: true, so the description adds marginal value.

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 concise: one sentence plus a tip. It includes a visual cue (💡 TIP) and uses front-loaded key information. No superfluous content. Could be slightly more structured with a clear 'When to use' section.

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?

The description lacks information on prerequisites (e.g., authentication, calendar permissions), what happens on success (no output schema), and potential side effects beyond the tip. Given the complexity (5 parameters, nested objects), the description feels incomplete for an agent to fully understand the tool's behavior.

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?

The description provides a tip that adds meaning to the body parameter (e.g., comment and sendResponse usage) beyond the schema's property definitions. However, schema coverage is 80%, so the description does not need to compensate much; it adds useful context for the body parameter.

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 clearly states 'Accept the specified event in a user calendar' with a specific verb and resource, and the tip clarifies it's for meeting invitations, distinguishing it from sibling tools like decline-calendar-event or tentatively-accept-calendar-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?

The description does not provide explicit guidance on when to use this tool versus other calendar event actions (e.g., tentatively-accept, decline). The tip is about how to use the optional body, not about selecting between alternatives.

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