create_basic_firewall_setup

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

The description adds minimal behavioral context beyond the destructiveHint annotation. It doesn't disclose whether existing firewall rules are overwritten, whether safe mode is recommended, or what specific rules are applied. For a destructive operation, this is a significant transparency 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 description is a single, front-loaded sentence that is concise and free of filler. It earns its place by stating the core purpose immediately.

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 is a destructive batch operation with a single optional parameter, the description lacks critical context such as the specific security rules included, potential side effects on existing rules, and usage guidance. The output schema exists but does not compensate for missing behavioral details.

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 has zero description coverage for the 'device' parameter, and the description does not mention or explain it. The parameter name is self-explanatory, but no behavior is described for the default null value or how the device is selected.

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 ('Creates') and the resource ('basic firewall setup') on a MikroTik device. It is specific enough to distinguish from other firewall-related tools like create_filter_rule, though it doesn't explicitly differentiate itself.

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 implies usage for setting up a baseline firewall but provides no explicit guidance on when to use it versus creating individual rules, nor any prerequisites or exclusions. This is similar to the update_drive example where impled usage alone earned a 2.

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