create_address_list_entry

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

Beyond the annotations, the description discloses significant operational behavior: hostname addresses generate dynamic child entries per resolved address, timeout entries are dynamic and do not survive reboot, and list_name is matched exactly including leading/trailing spaces. These are non-obvious and highly valuable for an agent. No contradiction with annotations.

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 concise: one clear purpose sentence followed by focused bullet notes. Every note addresses a real usage pitfall, and the most important behavior is front-loaded.

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 description covers the key creation semantics and edge cases, and an output schema exists so return values do not need description. It does not address whether family affects hostname resolution or mention duplicate/prerequisite behavior, but it is generally complete for a create tool.

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?

With 0% schema description coverage, the description compensates well for the most nuanced parameters: address, timeout, and list_name. It does not add meaning for family, comment, disabled, or device, but those are largely inferable from their types and the enum.

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 states the operation precisely: 'Adds an entry to an IPv4 or IPv6 firewall address list.' It names the action, the resource (firewall address list), and the supported address families, and is clearly distinguishable from the sibling list/get/update/remove/enable/disable address-list tools.

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 gives useful context about how entries behave, but it does not explicitly say when to use this tool versus alternatives like update_address_list_entry or remove_address_list_entry. The create versus modify/delete distinction is implied by the name and sibling set, but not stated.

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