remove_nat_rule

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

Annotations already declare destructiveHint=true and idempotentHint=true, so the safety profile is covered. The description adds only a note about rule_id sourcing, which is parameter semantics, not behavioral transparency. No additional behavior (e.g., permanence, side effects) is disclosed.

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 two sentences plus a concise note. It is front-loaded with the purpose and ends with a practical tip. Every word earns its place without fluff.

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 destructive delete operation, the description is adequate. It explains the critical rule_id input and relies on annotations for destruction warnings. Output schema exists, so return values are documented externally. A minor gap is the lack of any caution about permanence, but the annotations already cover destructive behavior.

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. It does clarify rule_id format ('use the ID from list output e.g. *1 or 0'), which adds meaning beyond the schema. However, the optional device parameter is not explained at all, leaving an incomplete picture.

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 'Removes a NAT rule from the MikroTik device' with a specific verb and resource. It distinguishes from sibling tools like create_nat_rule, update_nat_rule, and list_nat_rules.

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 no explicit guidance on when to use this tool versus alternatives like disable_nat_rule or update_nat_rule. The only note explains rule_id format, which is parameter guidance, not usage context.

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