Update Firewall Rule

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 only says 'Update an existing firewall rule' without explaining whether the update is a full replacement or partial modification, whether the rule is validated against existing firewall state, what happens if the rule ID does not exist, or any side effects such as reapplying the firewall. This is a significant gap for a mutation tool.

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 a single clear sentence with zero waste, which is efficient and front-loaded. However, it is so minimal that it under-specifies the tool's behavior, but this is more a completeness issue than a conciseness one. The structure is adequate for such a short description.

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 complexity (7 parameters, mutation, no annotations, no output schema), the description is highly incomplete. It does not explain the update semantics (e.g., whether all required fields must be provided, how action and direction interact, or what the response contains). This is inadequate for an AI agent to use safely and correctly.

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 100%, so the schema already documents all seven parameters including their types and descriptions. The description adds no additional meaning beyond what is in the schema, so a baseline score of 3 is appropriate.

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 'Update an existing firewall rule' with a specific verb ('Update') and resource ('firewall rule'), distinguishing it from sibling tools like create, delete, activate, or sync rules. It leaves no ambiguity about what the tool does.

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 that this tool is for modifying an existing rule rather than creating or deleting one, but it does not explicitly state when to use it versus alternatives. No exclusionary context or alternative tool names are mentioned, leaving the usage guidance solely to inference from the name and siblings.

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