Reminders Uncomplete Reminder

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

The annotations provide some basic hints, but the description adds no behavioral information such as side effects, state changes, or whether completion state is being modified. Without the tool name, there is no indication of what this tool actually does to a reminder.

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?

The description is short but not genuinely concise because it spends its only sentence on a generic delegation statement with no useful content. It is under-specified rather than efficiently front-loaded.

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?

Even though the schema is simple, the definition fails to state the tool's core function, expected inputs, or relationship to sibling reminder commands. An agent cannot confidently decide when to use this tool or what it will do from the provided description alone.

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?

The schema has one required parameter, reminder_id, with zero description coverage. The description does not explain what this identifier refers to, how it should be formatted, or what the tool does with it, so the agent receives no semantic value beyond the bare schema field.

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 only states that this is a delegated Apple domain tool exposed through Apple-Tools-MCP, which essentially restates the tool name and transport. It gives no verb, resource, or outcome, and does not distinguish it from reminders_complete_reminder or reminders_update_reminder.

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 about when to use this tool rather than the sibling reminder tools. No context, prerequisites, exclusions, or alternatives are mentioned, leaving an agent to infer the intended behavior solely from the name.

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