notion_get_appointment_by_gcal_id

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

Annotations already flag the tool as read-only and non-destructive. The description adds useful return behavior ('JSON dict of the appointment if found, or a not-found message') and the pre-sync duplicate-prevention role, which goes beyond the annotation hints.

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 compact and front-loaded: purpose, use case, args, and returns each earn their place. There is no filler or redundancy beyond the reasonable Args/Returns documentation.

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?

For a single-parameter read-only lookup with an output schema, the description fully covers what the tool does, when to use it, how to pass the parameter, and what to expect back. Nothing needed to call 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?

The Args block documents the required params.gcal_event_id parameter and its search meaning, which compensates for the reported low schema-description coverage. It does not add format constraints or examples, but for a single plain string ID this is sufficient.

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 first sentence states a specific action and resource: 'Find a Notion appointment by its linked Google Calendar event ID.' The lookup key is explicit, making the tool clearly distinct from siblings like notion_get_appointments or notion_get_tasks.

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 gives explicit when-to-use guidance: 'Use this before syncing to check whether a calendar event already has a corresponding Notion record, preventing duplicate entries.' It does not name alternative siblings or state when not to use it, so it falls just short of a 5.

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