reminders

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

No annotations are provided, so the description carries the full burden. It does not disclose that 'create', 'complete', and 'delete' are mutations, whether deletion is reversible, what permissions or Reminders.app state are required, or what 'open' actually does (UI launch vs. data read). None of this is recoverable from structured fields.

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 front-loaded sentence with no filler and no redundancy. Its brevity is appropriate in form, though it is brevity at the cost of substance given the seven-operation surface.

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 seven-operation, nine-parameter dispatcher with no annotations and no output schema, the description is far too thin. It never explains the relationship between 'list' and 'listById', distinguishes 'search' from 'open', or warns that create/complete/delete modify user data.

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 100%, including per-parameter notes on which operation each field serves, so the baseline is 3. The description adds no parameter meaning beyond the schema, which is acceptable here since the schema does the work.

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 names a specific resource (Apple Reminders / Member Berries) and lists five verbs, so the general purpose is clear. But it is a multiplexed dispatcher with seven operations and omits 'list' and 'listById' entirely, leaving the agent with an incomplete map of what the tool can do.

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 the sibling tools (briefing, calendar, notes, memberberries), and no guidance on how to choose among the seven operations. The operation enum in the schema is the only routing signal, and the description adds nothing about sequencing or prerequisites.

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