create_reminder

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

With no annotations, the description bears the full burden. It discloses that the tool creates a reminder and uses notification channels, but it does not mention required permissions, when notifications are sent (immediately vs. at reminder_time), or whether the action is reversible.

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?

A single concise sentence that is front-loaded with the core action and resource. It contains no redundant information and is appropriately brief for the tool's simplicity.

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 six parameters, no annotations, and no output schema, the description is too sparse. It leaves the meaning of the notification booleans unexplained and omits crucial context such as the actual sending behavior and any prerequisite conditions.

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 only 33%; the description does not clarify the notify_* booleans beyond the generic phrase 'canais de envio de notificação'. It fails to compensate for the lack of descriptions for the four notification parameters, leaving their behavior ambiguous.

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 'Agenda um novo lembrete' clearly indicates the action (scheduling) and resource (reminder), fully distinguishing it from sibling tools like create_task or create_task_list. It also mentions notification channels, which specifies the tool's unique scope.

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 usage context is implied by the tool's name and the sibling set (e.g., list_reminders, delete_reminder), making it apparent when to use this tool. However, there is no explicit guidance on when NOT to use it or which alternatives to prefer in specific scenarios.

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