firewall_allow

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

No annotations are provided, so the description bears full burden. It discloses auto-detection but fails to mention potential side effects (e.g., requires root, persistence of rule, handling of existing rules). For a system-modifying tool, this is inadequate.

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 consists of two short sentences with no unnecessary words. Every element serves a purpose: stating the action and a key feature (auto-detection). It is optimally concise.

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 lack of annotations and output schema, and the complexity of a firewall operation, the description is incomplete. It does not explain error handling, verification steps, or what the auto-detection implies for different systems. Additional context is needed for safe and correct usage.

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 low (33%: only protocol has a description). The tool description does not add any additional meaning to the parameters (port, protocol, session_id) beyond the schema. It misses the chance to explain parameters like session_id or valid port ranges.

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 'Open a port in firewall', which is a specific verb+resource. The auto-detection detail further distinguishes it from simple port listening tools. It is unambiguous and different from siblings like port_listen or ctf_listen_port.

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 implies usage for opening firewall ports with auto-detection of the underlying system, but it does not provide explicit when-to-use criteria, when not to use, or alternative tools like specific firewall commands. The guidance is implied but insufficient.

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