sdcloud_delete_nat_policy_rule_group

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

No annotations are provided, so the description must carry the burden. It discloses the effect of the 'ungroup_rules' parameter (keeps rules if true, deletes them otherwise) and notes the inability to update in place. However, it does not describe potential side effects like cascading deletions, permission requirements, or what happens to the rule group's position. The transparency is moderate.

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 extremely concise, consisting of two sentences and a note—about 30 words. It front-loads the primary action and efficiently conveys the key information: what it does, the optional parameter behavior, and an important limitation (no update). Every sentence adds value without redundancy.

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 delete operation with an optional parameter, the description covers the main functionality and the ungroup option. However, it omits any mention of error conditions (e.g., if policy or group does not exist), prerequisites, or return values. With no annotations or output schema, the tool feels slightly under-documented for an agent to safely invoke it without additional 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 input schema has no descriptions (0% coverage). The description explains the purpose of 'ungroup_rules' but does not provide details on 'group_id' or 'policy_id' beyond being identifiers. It partially compensates for the low schema coverage, but more detailed descriptions of the IDs (e.g., format, source) would improve semantics.

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 ('Delete a rule group within a NAT policy') and the resource. It also explains the optional behavior of ungrouping rules. While it distinguishes itself from sibling delete tools like sdcloud_delete_nat_policy_rule by specifying the resource as 'rule group', it does not explicitly contrast with all siblings, which is acceptable given the clarity.

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 provides guidance on when to use this tool (to delete a rule group) and includes an important note that rule groups cannot be updated in place, so delete and recreate instead. However, it does not explicitly state when not to use this tool or mention any prerequisites (e.g., policy existence). The guidance is adequate but not comprehensive.

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