create_dfw_policy

Create a new Distributed Firewall security policy with custom category, priority, and stateful inspection for network microsegmentation.

Instructions

[WRITE] Create a new DFW security policy.

Args: policy_id: Unique policy ID (alphanumeric, hyphens, underscores). display_name: Human-readable policy name. category: Policy category — Emergency, Infrastructure, Environment, or Application (default: Application). sequence_number: Priority order; lower number = higher priority (default: 10). stateful: Whether to track connection state (default: True). description: Optional description. target: Optional NSX Manager target name from config.

Behavior3/5

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

Annotations already indicate non-readonly, non-destructive, non-idempotent. Description adds '[WRITE]' and parameter details but no additional side-effect disclosure beyond what annotations imply.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Well-structured with a summary line followed by Args list. Efficient use of space, though it could be slightly more concise.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Covers input parameters well but lacks information about success output or prerequisites. No output schema makes return value important; description omits it.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters5/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema has no parameter descriptions (0% coverage). Description compensates fully by explaining each parameter, including format for policy_id and defaults for category, sequence_number, stateful, etc.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Description starts with '[WRITE] Create a new DFW security policy,' clearly indicating verb and resource. This distinguishes it from sibling tools like create_dfw_rule or delete_dfw_policy.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No explicit guidance on when to use this tool versus alternatives. Lacks context like 'Use this to define a new policy; for rules within a policy use create_dfw_rule.'

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