outlook_respond_to_invite

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

With no annotations, the description carries full burden but only says 'Respond to a meeting invitation'. It fails to disclose side effects (e.g., sending a response email), default behavior (sendResponse defaults to true), or required permissions. The tool's mutation effect is implied but not explicitly stated.

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 a single concise sentence that communicates the core action without unnecessary words. However, it is so brief that it omits important context; one could argue it is under-specified rather than efficiently concise.

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 4 parameters, no annotations, and no output schema, the description is too sparse. It does not explain that the eventId must belong to an invitation, that response sends a reply, or what happens after a response. More detail is needed for complete understanding.

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 100%, so baseline is 3. The description adds no extra meaning beyond what the schema already provides for each parameter. The enum values for 'response' are clear from the schema, and the comment parameter is self-explanatory.

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 'Respond to a meeting invitation' clearly states the verb (respond) and resource (meeting invitation), distinguishing it from sibling tools like outlook_create_event or outlook_update_event. It identifies a specific action not covered by other tools.

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 provides no guidance on when to use this tool versus alternatives such as outlook_update_event or outlook_create_event. It does not specify that this is for invitations received from others, nor does it mention prerequisites like needing an invitation event ID.

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