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

No annotations are present, so the description carries the full behavioral burden. It conveys a read-only retrieval and adds an important nuance about 'current occurrence' state, but it does not address not-found behavior, error handling, or explicit no-side-effect guarantees beyond the title's 'Read' verb.

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 that states the core purpose and then adds meaningful detail about what is included. There is no filler or redundancy.

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 one-parameter getter with no output schema, the description sufficiently outlines the return content by naming steps, messages, timing, and current-occurrence outcome. It leaves unspecified behavior for invalid or missing reminder IDs, but this is a minor gap for a simple read tool.

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 coverage is 100% for the single reminder_id parameter, and the input schema already describes it straightforwardly. The tool description adds no parameter-level detail, so the baseline 3 is appropriate.

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 clearly identifies the tool as retrieving the full detail of a single reminder-listing its message, timing, steps, and current-occurrence outcome. It is semantically distinguishable from siblings like list_reminders and get_reminder_status, though it does not explicitly name those alternatives.

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?

No guidance is given on when to use this tool versus get_reminder_status or list_reminders. The single-reminder framing implies one use, but there are no explicit exclusions, prerequisites, or routing cues to help an agent decide between siblings.

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