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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only states the core action (creating a rule) without detailing side effects, prerequisites, permissions, or behavior on duplicate rules. The description does not contradict annotations but adds minimal behavioral context beyond the bare action.

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, front-loaded sentence that immediately conveys the tool's purpose. There is no redundant or extraneous information. It is appropriately sized for a simple create operation.

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, 3 enums) and lack of output schema or annotations, the description is too sparse. It does not explain expected outcomes, error scenarios, the need for an existing group, or how the optional 'format' parameter affects the response. The schema covers parameter syntax but not the broader usage context.

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?

The schema covers 100% of parameters with descriptive text, so the baseline is 3. The description itself adds no parameter information, but it doesn't need to because the schema already explains each field well. No extra meaning or context is provided beyond what the schema offers.

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 action ('Create'), the resource ('firewall rule'), and the context ('in a group'). It distinguishes this from sibling tools like create_firewall_group or delete_firewall_rule. The verb and object are specific and unambiguous.

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 gives no guidance on when to use this tool versus alternatives. It does not mention that an existing firewall group is required, nor does it point to related tools like list_firewall_rules or create_firewall_group. Usage context is only implied by the word 'create' and the schema's required group_id.

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