listReminderLists

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

Description states it returns 'all reminder lists', indicating an exhaustive read operation. No annotations exist, so the description carries full burden. It does not disclose authentication needs, sorting, or other behavioral traits, but for a simple get operation, it is adequate.

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?

Single sentence of six words, extremely concise and front-loaded. No extraneous content.

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 zero-parameter tool with no output schema, the description is sufficiently complete. It clearly states the operation and resource. It could describe the output structure, but the concept of a reminder list is common and the operation is straightforward.

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?

No parameters exist, so the input schema covers 100%. The description adds no parameter information, but none is needed. It implicitly confirms the tool takes no input.

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?

Description clearly states the verb 'Get' and resource 'all reminder lists from Apple Reminders'. It distinguishes from siblings like getReminders (which likely gets items within a list) by explicitly naming the resource as lists.

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?

No explicit guidance on when to use versus alternatives. Usage is implied for listing all reminder lists, but no when-not-to-use or alternative hints are provided.

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