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

Annotations already declare readOnly, idempotent and open-world behavior, so the safety profile is covered. The description adds value beyond that by spelling out the returned account fields (uuid, name, email, locale, admin/child flags, sign-in count), which matters because no output schema exists. It does not mention auth failure behavior or rate limits, keeping it short of a 5.

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?

One front-loaded sentence with zero filler; the resource comes first and the field list follows as compact, comma-separated detail. Every clause earns its place.

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 zero-parameter read tool with no output schema, the enumerated return fields plus the annotations give an agent nearly everything needed to call and interpret it. Only the auth/session precondition and error case (e.g., no signed-in user) are unstated.

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 tool takes zero parameters, so the baseline of 4 applies and there is nothing for the description to disambiguate. No parameter semantics are needed or missing.

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?

States a specific verb and resource ('Get the signed-in Remind account') and enumerates the exact fields returned, which is precise and unambiguous. It does not explicitly position itself against siblings like remind_get_notification_settings or remind_get_classes, though the subject matter is naturally distinct enough that confusion is unlikely.

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?

Used when the agent needs the current user's identity, but this is only implied by 'signed-in account' – there is no explicit statement of when to call it, no prerequisites (e.g., an authenticated session is required), and no named alternatives. Adequate but leaves routing to inference.

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