Apple Preview Create Reminder With Defaults

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

Annotations already declare readOnlyHint and idempotentHint, so the safety profile is covered. The description reinforces the preview behavior and adds that it uses the configured default reminder list, but it doesn't disclose additional edge behavior; this is acceptable but not rich.

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?

One short, front-loaded sentence that conveys both the preview nature and the default-list context. No filler or repetition of obvious schema details.

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?

The description is sufficient for selecting the tool and understanding that it is a read-only preview, and the output schema covers return values. However, with five parameters and zero schema descriptions, the input semantics are not fully specified, leaving a meaningful gap for correct 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% and the description provides no explanation of title, notes, list_id, due_date, or priority. The agent must guess date formats and priority semantics from parameter names alone, so the description fails to compensate for the missing schema documentation.

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?

It states a specific verb ('Preview') and a specific resource ('how Apple-Tools will create a reminder'). The 'Preview' wording clearly separates this from the actual creation sibling apple_create_reminder_with_defaults, so the operation is unambiguous.

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 'Preview' framing implies this is the dry-run tool to use before an actual creation, but the description never explicitly names the alternative creation tool or states when not to use it. The intended usage is inferable rather than stated.

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