ews_update_meeting_confirmed

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

With no annotations provided, the description carries full burden. It discloses key requirements (confirm=true, confirmation_id) and field limitations, but it does not mention behavioral traits such as the default sending of meeting invitations, permission needs, or idempotency. Some transparency is present but gaps remain.

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 extremely concise: two sentences that front-load the purpose and immediately provide essential requirements and limitations. Every sentence contributes meaning without fluff.

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?

Given the tool has 11 parameters (4 required) and no output schema, the description covers the core workflow (preview then confirmed) and lists updatable fields. It lacks details on return behavior or the send_meeting_invitations parameter, but it is sufficiently complete for the primary use case.

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% (baseline 3). The description adds value by emphasizing that only subject, start, end, location, and body are supported for updates, which clarifies the role of id and changekey as identifiers. This context goes beyond the schema descriptions.

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 the verb 'Update an existing meeting' and the specific resource. It distinguishes from sibling tools like ews_update_meeting_preview by emphasizing the confirmed step, and it lists the limited set of supported fields, making the purpose highly specific.

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 explicitly says when to use this tool: after obtaining confirmation_id from ews_update_meeting_preview and with confirm=true. It provides clear context but does not explicitly exclude other sibling tools like create or cancel, though the name and description imply the use case.

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