set_reminder

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

The description discloses the datetime format and that it returns a success/error message. However, it does not mention potential errors (e.g., invalid datetime), permissions, or side effects beyond creating the 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 structured with Args/Returns and is reasonably concise, though the formatting adds some verbosity. Every sentence adds value.

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?

Given the low complexity and presence of an output schema, the description covers purpose, parameters, and return value. However, it lacks usage guidelines and behavioral details like time constraints, making it slightly incomplete.

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?

With 0% schema description coverage, the description fully compensates by explaining each parameter's meaning, providing an explicit datetime format, and giving an example for list_name with a default value.

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 states the tool sets a reminder with parameters for name, datetime, and list_name. While it distinguishes from siblings implicitly, it does not explicitly differentiate from update_reminder or reschedule_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?

No guidance is provided on when to use this tool versus its siblings (e.g., update_reminder, complete_reminder, delete_reminder). The agent must infer from the name alone.

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