Apple Capture Follow-Up From Mail

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

Annotations provide only basic hints, so the description carries additional weight. It discloses that the tool creates two artifacts (a reminder and an archival note) and uses assistant defaults, which is meaningful behavioral context. However, it does not clarify side effects such as whether the source email is also archived, whether repeated calls duplicate items, or how defaults affect results.

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 a single, front-loaded sentence with no filler. It conveys the core purpose, the default-driven behavior, and the two outputs quickly and efficiently.

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 tool with six parameters, two side effects, and dependency on assistant defaults, this description is too sparse. It does not explain the boolean flags, the meaning of 'archival note,' prerequisites like Mail permissions, or whether a preview step should be used first. Even with an output schema present, the agent lacks enough context to invoke this tool confidently in varied situations.

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 the description must compensate, but it only mentions 'assistant defaults' without explaining parameter roles. It does not clarify how create_reminder and create_note interact with reminder_title and note_title, what format due_date expects, or that message_id identifies the source email.

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: turning an email into a reminder and an archival note. This clearly differentiates it from pure reminder-creation or note-creation tools, though it does not explicitly distinguish it from the apple_preview_follow_up_from_mail sibling.

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?

The description implies this is the tool to use when assistant defaults are acceptable, but it gives no explicit when-to-use or when-not-to-use guidance. It does not name alternatives like apple_create_reminder_with_defaults, apple_create_note_with_defaults, or apple_archive_message, so an agent must infer the right context.

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