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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states it's a list operation, implying read-only behavior, but doesn't clarify if it's safe (non-destructive), requires authentication, has rate limits, or returns paginated results. The mention of 'scope the query' hints at filtering, but lacks depth on behavioral traits.

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 appropriately sized and front-loaded, with the core purpose stated first followed by parameter details. Each sentence adds value without redundancy. However, the 'Args:' section could be integrated more seamlessly, and it lacks a concluding note on output or behavior, slightly affecting structure.

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 moderate complexity (3 parameters, no annotations, but with an output schema), the description is partially complete. It covers parameters well but misses behavioral context (e.g., safety, permissions) and doesn't leverage the output schema to hint at return values. For a list tool in a security management context, more guidance on usage and constraints would enhance completeness.

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%, so the description must compensate. It adds meaningful context for all three parameters: 'folder' is explained as scoping the query, 'position' clarifies it's for rule position with default and options, and 'tsg_id' notes it's optional with a default value. This goes beyond the schema's basic titles, providing practical usage insights.

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 ('List') and resource ('NAT rules in a folder'), making the purpose specific and understandable. However, it doesn't explicitly differentiate from sibling tools like 'scm_get_nat_rule' or 'scm_create_nat_rule', which would require mentioning it's a bulk listing operation versus single retrieval or creation.

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 description provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., needing folder access), compare to other list tools (e.g., 'scm_list_security_rules'), or specify use cases (e.g., for auditing or configuration review). This leaves the agent without contextual usage cues.

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