Rename Reminder List

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

No annotations beyond title, so description carries burden. It states 'rename' implying mutation, but lacks details on permissions, idempotency, or side effects. For a simple rename, this is adequate 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?

Single sentence, concise. Front-loads the action and resource. Could be slightly improved by separating identification methods, but overall efficient.

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 output schema exists and low parameter count, description is adequate but lacks clarity on how to use the identifier parameters. It doesn't explain that 'list_name' and 'reminders_list_id' are alternatives, which might confuse an agent.

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 has 3 params with 0% description coverage. The description adds some meaning by mentioning identification via 'stable id or friendly name', corresponding to 'reminders_list_id' and 'list_name'. However, it doesn't clarify that exactly one of these should be provided, nor the relationship between them.

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 action ('rename'), the resource ('reminder list'), and the identification method ('by stable id or friendly name'). It distinguishes from sibling tools like 'reminders_rename' which renames a reminder item, not a list.

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 this tool versus alternatives. The description implies use for renaming lists, but doesn't clarify differences with 'reminders_rename' or 'reminders_create_list'. Sibling names provide some context, but the description itself lacks usage instructions.

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