b24_calendar_create

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

With no annotations, the description carries the full burden for behavioral disclosure, yet it only says it creates an event. It does not mention whether a webhook is required for writes, what side effects occur, whether the operation is idempotent, or what response the caller should expect.

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, front-loaded sentence with no filler. Every phrase adds relevant information about what the tool does and what the event can include.

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 11 parameters, no output schema, and no annotations, a one-sentence description is not enough to completely orient an agent. It omits the user/group/company calendar type dimension, authorization/webhook nuances, required-field guidance, and any indication of the return value.

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 description maps to some parameters (attendees, location, remind), but mostly repeats property names already visible in the schema. Schema description coverage is only 55%, and the description does not clarify undocumented parameters such as type, owner_id, description, or webhook_url.

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 states a specific action ('Crea un evento en el calendario') with a clear resource and identifies notable included features: participants, location, and reminders. It clearly distinguishes this tool from calendar listing or other create tools in the sibling set.

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 'use this to create a calendar event' but provides no explicit guidance about when to prefer it over alternatives or any exclusions. There is no mention of the read-only default without a write webhook, which would be useful usage context.

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