UpdateRule

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

The description offers no behavioral information such as whether the operation is destructive, requires specific permissions, or has side effects. With no annotations provided, the description fails to compensate.

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?

While very short, the description is under-specified and not concise in a helpful way. It does not provide any actionable information beyond the tool name.

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 has a nested object parameter and many sibling tools, the description is completely inadequate for an AI agent to understand the purpose, input requirements, or behavior. It lacks essential details needed for correct invocation.

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?

The input schema has one parameter 'body' with description 'Request body', which is vague. The description adds no further meaning about the structure or required fields of the body. Although schema coverage is 100%, the schema itself provides minimal semantics.

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 'Update Rule' is a tautology, restating the tool name without adding any specifics about what kind of rule is updated or what the update entails. It does not distinguish from siblings like CreateRule, DisableRule, or EnableRule.

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 or when not to. There is no mention of prerequisites, alternatives, or context in which UpdateRule should be preferred over other rule-related tools.

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