helpers_set_input_datetime

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

No annotations are provided, so the description bears full responsibility. It only gives format requirements but does not disclose behavior when multiple parameters are provided, default actions, or side effects like overwriting existing values.

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 sentence that efficiently conveys purpose and format. It is front-loaded with the key action. Minor improvement could be adding structure for clarity, but it remains succinct.

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 simple set operation, the description covers the basic purpose and format. However, it omits details about parameter interactions and error cases. Since an output schema exists, return values need not be explained, but behavioral context is lacking.

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%. The description adds format hints for date, time, and datetime, which helps understand the string format. However, it does not explain the entity_id parameter or how the three optional parameters relate to each other.

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 verb 'Set' and the resource 'input_datetime', and provides specific format guidance (date, time, datetime), distinguishing it from sibling helpers for boolean, number, etc.

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 explicit guidance on when to use vs. alternatives. The tool name and date/time/datetime formats imply it's for input_datetime helpers, but no exclusion or comparison is provided.

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