Apple Create Reminder With Defaults

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

Annotations only indicate a non-idempotent, non-destructive action. The description adds an important behavioral trait not visible in the schema: reliance on a configured default reminder list when list_id is omitted. It also clarifies that the operation is a create/write. No contradiction with annotations.

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 front-loaded sentence states the core behavior and the scoping condition. No filler words; every element earns its place.

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 small create tool with an output schema and mostly self-evident parameters, the description covers the central decision (when the default list applies) and the action. It doesn't describe how to configure the default list or mention the preview sibling, but these are peripheral for direct invocation.

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 description coverage is 0%, so the description needs to shoulder the explanatory burden. It provides semantic meaning only for list_id (omission triggers default list). It does not explain title, notes, due_date, or priority values/formats, leaving the agent to guess from parameter names and default values.

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 names a specific action ('Create a reminder') and a specific resource, then adds the distinctive condition ('using the configured default reminder list when list_id is omitted'). This separates it from the generic reminders_create_reminder and other apple_*_with_defaults siblings without requiring schema inspection.

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 phrase 'when list_id is omitted' gives a clear usage condition: this tool is for creating reminders without a specific list. It does not explicitly name the alternative (e.g., reminders_create_reminder) for cases where a list_id is supplied, so the exclusion is implied rather than stated.

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