helpers_set_input_datetime

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

No annotations provided, so description carries full burden. Only states 'Set input_datetime' and format hints; no disclosure of side effects, validation behavior, or permissions. Minimal behavioral context.

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?

Two sentences, no redundancy. Front-loads the action and efficiently conveys parameter formats.

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?

Covers basic purpose and parameter formats, but lacks details on return values (output schema exists but not described), error handling, and relationship between parameters. Adequate for a simple tool but not fully complete.

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 0%, so description adds value by specifying expected formats (YYYY-MM-DD, HH:MM:SS). However, it does not explain interplay between parameters (e.g., what happens if both date and time are set vs. datetime) or validation behavior.

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?

Clearly states the action 'Set input_datetime' and specifies what can be set (date, time, datetime). Distinguishes from sibling helpers like helpers_set_input_boolean and helpers_set_input_number.

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?

Provides format strings but no guidance on when to use this tool versus alternatives. No context for selecting between date, time, or datetime parameters, nor when to prefer this over other input helpers.

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