create_firewall_alias

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

The description only says 'Create' with no mention of side effects, permissions, idempotency, or error scenarios. It lacks behavioral context beyond creation.

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 very short and without extraneous text. It efficiently lists parameters with minimal but useful explanations.

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?

The tool is simple, but lacks details on error handling (e.g., duplicate alias), output format (though output schema is present), or any preconditions. Minimal but adequate for a straightforward create operation.

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 has 0% description coverage, so description must compensate. It provides brief descriptions for each parameter and an example for cidr. However, no constraints (length, format) are given for name or comment, only cidr example.

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 tool creates a firewall alias and explains what an alias is (named IP address or CIDR). It distinguishes from siblings like create_firewall_ipset and add_firewall_ipset_entry.

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?

No guidance is provided on when to use this tool versus alternatives, no prerequisites, and no context for when it should not be used.

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