add_firewall_rule

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

With no annotations, the description carries the full burden of behavioral disclosure. It only mentions the type options but does not describe what happens on success or failure, permissions needed, side effects, or any other behavioral traits. The existence of an output schema is not mentioned, so the agent gains little insight into the tool's behavior.

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 very short (two sentences) and avoids unnecessary text. However, the brevity comes at the cost of usefulness; it could be restructured to list key parameters or provide a clearer overview. It is not verbose but lacks substance.

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 8 parameters (2 required), no parameter enums, and no schema descriptions, the description is woefully incomplete. It does not reference the output schema or explain the role of any parameter except type. The context signals indicate high complexity, but the description does not address this.

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%, yet the description only adds meaning for the 'type' parameter by listing its valid values. The other 6 parameters (interface, ipprotocol, protocol, source, destination, dstport, descr) receive no explanation. The description fails to compensate for the lack of schema descriptions.

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 'Add' and the resource 'firewall rule', and gives a sample value for the type parameter. It distinguishes from sibling operations like delete_firewall_rule and list_firewall_rules by the action, though it doesn't explicitly contrast with them.

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 versus alternatives. There are no prerequisites, context expectations, or when-not-to-use instructions. The sibling list includes other firewall-related tools but no differentiation is given.

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