CreateRule

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

With no annotations, the description must fully disclose behavioral traits, but it only says 'Rule creation'. It does not mention side effects, required roles, rate limits, or what happens upon creation (e.g., immediate activation). This is a critical gap.

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 extremely concise (two words) but under-specified. It lacks necessary content to be useful, making it more of a placeholder than a properly sized description.

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 tool's complexity (nested object parameter, numerous rule-related siblings, no output schema), the description is completely inadequate. It fails to convey even basic usage information.

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% with parameter 'body' described as 'Request body'. While the schema itself documents the parameter, the description adds no additional meaning about expected fields, structure, or constraints beyond the placeholder 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 'Rule creation' is a near-tautology of the tool name. It states the verb and resource but fails to differentiate from similar siblings like UpdateRule, EnableRule, or RunRule, providing no unique scope.

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 on when to use CreateRule versus other rule-related tools. No context about prerequisites, necessary permissions, or typical use cases is provided.

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