create_reminder

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only mentions that the tool uses Beijing time, which is already a schema default, and does not describe side effects, prerequisites, authentication, or behavior when creating child tasks.

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, focused sentence with no filler. It front-loads the action ('Create') and conveys the most distinctive contextual detail (Beijing time) 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 9 parameters, no annotations, and an output schema that does not cover input semantics, this description is severely inadequate. It leaves users without essential guidance on parameter usage, relationships, or operational constraints, making it nearly impossible to invoke the tool correctly without external knowledge.

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% for 9 parameters. The description hints at time_zone_name via 'Beijing time' and parent_reminder_id via 'child task', but fails to explain the required 'title' or any other parameters like due, all_day, flagged, list_id, priority, and description.

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's action (create) and resource (reminder or child task), and adds the key detail of Beijing time. It distinguishes itself from sibling tools like update_reminder and delete_reminder by focusing solely on creation.

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 verb 'create' implies when to use the tool, but the description offers no explicit guidance on when to use it versus alternatives such as update_reminder or set_reminder_completed. It mentions no exclusions or specific scenarios beyond the basic action.

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