apple_reminders_create_list

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

Annotations already declare the safety profile (not read-only, not idempotent, not destructive, open world), so the description only needs to add context. It contributes the account-scoping requirement, but says nothing about duplicate list names, error behavior, or what happens to an existing list with the same name.

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 short sentence with the action front-loaded and no filler. The phrasing 'in an exact account ID' is slightly clunky but costs nothing in length.

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 mutation tool with no output schema and zero parameter documentation, the description is too thin: it omits name, omits how to obtain a valid accountId, and omits any post-creation behavior or duplicate handling.

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% for both parameters, so the description must compensate. It hints that accountId must be an exact account identifier, but gives no meaning, format, or source for it, and never mentions the required 'name' parameter at all.

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?

States a specific verb and resource (create a Reminders list), which cleanly separates it from siblings like apple_reminders_rename_list and apple_reminders_delete_list. The trailing phrase 'in an exact account ID' is awkward but does convey the target 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?

There is no when-to-use guidance, no mention of where the required accountId comes from (e.g., apple_reminders_list_accounts), and no alternatives or exclusions. The agent must infer the workflow entirely.

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