ghl_calendar_notification_create

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

The description indicates it's a write operation (complementing readOnlyHint=false) and adds that multiple notifications can be created but limited to a single calendar. However, it does not disclose behavior like idempotency, error states, or effects on existing notifications.

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 short with two sentences plus endpoint/scopes. It is mostly concise, though the first sentence repeats the title. Key constraints are front-loaded.

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 moderate complexity (array of nested objects) and no output schema, the description lacks critical context: response format, error handling, required OAuth scope details (listed but not explained), and behavior for partial failures or large batches.

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 50% (body field has a generic description, calendarId has none). The description does not explain calendarId or add meaning beyond the schema; it only implies the body array allows multiple notifications, which is already evident from the schema type.

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 it creates calendar notifications, either one or multiple, and is specific about the resource (calendar) and action (create). It distinguishes from sibling tools like delete, get, list, and update.

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 implies usage by stating 'Create Calendar notifications, either one or multiple' and includes a constraint ('must be for single calendar only'). However, it does not explicitly guide when to use this over alternatives (e.g., update) or provide prerequisites.

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