add_firewall_drop

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

No annotations are provided, so the description must cover behavioral traits. It only states that the tool adds a rule and requires write permission, but lacks details on potential side effects (e.g., rule insertion order, duplication, or impact on existing traffic). This is insufficient for a write operation.

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 short and front-loaded with the action. However, mixing Indonesian and English may slightly reduce clarity. Otherwise, it is concise and to the point.

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 3 simple parameters, no output schema, and no annotations, the description covers the essential purpose and parameter defaults. However, it lacks behavioral completeness (e.g., rule ordering, error conditions). Adequate but not comprehensive.

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 add meaning to parameters. It explains src_address with an example, and provides defaults for chain and comment. This adds significant value beyond the schema's bare types.

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 that the tool adds a firewall rule to DROP traffic from a specified src_address. This specific verb and resource distinguish it from sibling tools like delete_firewall_rule or set_firewall_rule_enabled.

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 mentions a prerequisite: 'BUTUH ALLOW_WRITE' (needs write permission), which guides usage. It does not explicitly state when not to use this tool versus alternatives, but the context of adding a drop rule is well-defined and no sibling tool performs the same function.

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