apple_reminders_rename_list

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

Annotations already declare destructiveHint=true, idempotentHint=true, and openWorldHint=true, so the safety profile is covered structurally. The description adds only the 'by ID' targeting detail and does not disclose what the rename replaces, whether the old name is lost, or any failure behavior for a missing ID.

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 clause with zero filler and the action front-loaded. It is arguably too terse for a two-parameter mutation, but nothing in it is wasted.

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 simple two-parameter mutation with safety covered by annotations and no output schema, the essentials are present. However, the absence of any schema descriptions leaves the parameter contract thin, and the description does not mention whether the renamed list must be uniquely named or what is returned.

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 both parameters rely on the description for meaning. 'By ID' clarifies the id parameter and 'Rename ... list' implies name is the replacement label, which is partial compensation, but format constraints, uniqueness requirements, and list-reference semantics remain undocumented.

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 states a specific verb and resource ('Rename a Reminders list') and identifies the targeting key ('by ID'). It is distinguishable from siblings like apple_reminders_create_list or apple_reminders_delete_list by the verb alone, though it does not explicitly contrast with them.

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 guidance on when to use this tool versus apple_reminders_update, apple_reminders_create_list, or apple_calendar_rename_calendar. No prerequisites (existing list, account scope) or exclusions are mentioned.

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