sdcloud_update_nat_policy_rule

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

No annotations are provided, and the description only says 'Update', implying mutation. It lacks details on behavioral traits like idempotency, required permissions, or effects on related resources.

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 at 5 words, front-loading the core action and scope. However, it may be too brief for adequate comprehension.

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?

No output schema, and the description omits details about return values, side effects, or prerequisites. Given the three required parameters and nested body, the description is insufficient for complete tool understanding.

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 33% (only 'body' has a description). The description does not explain 'rule_id' or 'policy_id' beyond their names, and 'body' is vaguely described as 'JSON request body matching the target Security Director Cloud schema.'

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 an ungrouped NAT policy rule' clearly states the verb (Update), resource (NAT policy rule), and scope (ungrouped), distinguishing it from sibling tools like sdcloud_update_nat_policy_rule_in_group.

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 'ungrouped' qualifier implies when to use this tool vs grouped alternatives, but no explicit when-to-use or when-not-to-use guidance is provided.

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