sdcloud_delete_firewall_policy_rule_group

Delete a firewall policy rule group with an option to retain its member rules by ungrouping them.

Instructions

Delete a rule group within a firewall policy scope. If ungroup_rules is true, member rules are kept and ungrouped instead of deleted.

Behavior2/5

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

No annotations exist, so the description carries full burden. It explains the conditional behavior of ungroup_rules but does not disclose whether the operation is destructive, reversible, or any side effects. The description lacks transparency on what happens to rules when ungroup_rules is false.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely concise with two sentences: one for the primary action and one for a key parameter behavior. No irrelevant information, making it easy to parse quickly.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the complexity (4 parameters, no output schema, no annotations), the description is too brief. It omits return values, error conditions, and the expected state after deletion. The meaning of policy_uuid and group_uuid is left to inference from the name.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The description adds meaning to the ungroup_rules parameter by explaining its effect. However, the required parameters policy_uuid and group_uuid have no explanation in the schema or description, despite schema coverage being low (25%). The description partially compensates but not fully.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action (delete) and the resource (rule group) within a specific context (firewall policy scope). It distinguishes it from the sibling delete_firewall_policy_rule by focusing on groups. The additional detail about ungroup_rules further clarifies the purpose.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives (e.g., delete_firewall_policy_rule for individual rules). It does not mention prerequisites (e.g., existence of the group or policy) or when to set ungroup_rules to true vs false.

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