firewall_get_rule

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

No annotations are provided, so the description carries the full burden. The verb 'Get' and the 'Returns: Firewall rule information' line make the read-only nature clear, which is useful. However, it does not disclose any potential errors, permission requirements, or other behavioral traits beyond the obvious read operation. This is adequate but not rich.

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 short, front-loaded with the purpose, and uses clear Args/Returns sections. Every sentence is informative. The 'Returns' line is somewhat redundant since an output schema exists, but it is not harmful and the overall structure is clean.

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?

For a simple get-by-two-IDs operation, the description is mostly complete: it names the resource, defines both parameters with an example, and the output schema covers return values. It does not explain how to obtain the rule ID or when to use list rules first, but that is not strictly required for a direct get call.

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. The Args section defines both parameters and adds meaningful context, especially for firewall_group_id, which can be a description like 'web-servers' or a UUID. It could be even more explicit about the format of firewall_rule_id, but it still goes well beyond the bare schema.

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 uses a specific verb and resource: 'Get information about a specific firewall rule.' The word 'specific' clearly distinguishes it from listing all rules or fetching a group, and siblings like firewall_list_rules and firewall_get_group reinforce that contrast. An agent can tell exactly what this 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?

There is no explicit guidance about when to use this tool versus alternatives such as firewall_list_rules or firewall_get_group. No 'use this when...' statement and no mention of sibling tools. Usage is only implied by the tool name and parameter requirements, which is weaker than clear context or exclusions.

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