lb_get_firewall_rule

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

With no annotations, the description carries full behavioral burden; 'Get details' does communicate a non-mutating read, which is the primary safety-relevant trait. It does not mention explicit read-only status, error behavior, or prerequisites, but for a simple detail-getter this is a minor gap.

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 purpose is front-loaded in a single sentence and the Args/Returns block is compact and easy to scan. There is no filler or redundant explanatory prose.

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?

Because an output schema exists, the vague 'Firewall rule details' return statement is acceptable. The two required parameters are both present in the description, and the accepted formats for `load_balancer_id` are clearly stated. The only real absence is explicit disambiguation from the firewall-group rule tools.

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 coverage is 0%, so the description must document the parameters itself. It adds genuinely useful detail for `load_balancer_id` ('ID or label' with examples), but `firewall_rule_id` is only restated as 'The firewall rule ID', adding little beyond the parameter name.

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 opening line 'Get details of a specific firewall rule' is a clear verb+resource statement and correctly indicates a single-entity read operation. It does not explicitly distinguish this load-balancer-scoped rule from the sibling `firewall_get_rule`, but the `load_balancer_id` parameter and `lb_` prefix make the scope inferable.

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 given about when to use this tool versus the many related siblings such as `lb_list_firewall_rules`, `firewall_get_rule`, or `firewall_list_rules`. The intended context is only implied by the parameter names and tool name.

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