validate_calendar_connection

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

Annotations declare readOnlyHint=false, which looks surprising for an 'Inspect' tool until the description explains that setting requestPermission raises the macOS full-access prompt — a genuine system-level side effect an agent could not infer. It stops short of saying what happens on denial or non-interactive contexts.

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?

Two short sentences, the action front-loaded and the conditional parameter guidance second. Nothing is redundant with the schema or annotations.

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?

An output schema exists, so return values need no explanation, and the one parameter is covered. The remaining gap is that 'configured target' is never defined — an agent does not know what target is being validated or what a failing result means.

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 0%, so the description must carry the single parameter, and it does: requestPermission is tied to the macOS full-access prompt and implicitly gated ('only when the user wants'). The default of false comes from the schema rather than the text, and the exact prompt behavior is not spelled out further.

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 (Inspect) and resource (Apple Calendar permission and configured target), which clearly separates it from validate_notion_connection. It does not explicitly name siblings or say when to prefer it over publish_to_calendar, but the scope is unambiguous.

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 second sentence gives a conditional rule for one parameter ('only when the user wants the macOS full-access prompt'), which is strong guidance. However, there is no statement of when to call this tool at all versus the publication siblings, and no note about running it before publish_to_calendar.

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