add_ipv6_address

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

The description adds behavioral context beyond the annotations by explaining parameter-specific behaviors: address format when using from_pool, default for advertise, and the meanings of eui_64 and no_dad. Annotations already declare non-destructiveness, and no contradiction is present. It does not discuss broader side effects, but the added parameter behavior is valuable.

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, front-loaded with the purpose, and uses structured notes for parameter details. Every sentence provides useful information without redundancy, making it easy for an agent to parse and apply.

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 tool with 9 parameters, the description provides essential details for the non-obvious parameters while the output schema likely covers return values. It lacks explanation for some generic parameters like disabled and comment, but the guidance is sufficient for successful invocation in most cases.

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?

Since the schema has 0% description coverage, the description compensates by explaining the format and semantics for key parameters (address, advertise, eui_64, from_pool, no_dad). It leaves device, comment, disabled, and interface undocumented, but the covered parameters are the most critical for correct use.

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 uses a specific verb ('Adds') and a clear resource ('IPv6 address to an interface on the MikroTik device'), making its function explicit. It also distinguishes itself from sibling tools like list_ipv6_addresses, get_ipv6_address, and remove_ipv6_address by clearly indicating the action.

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 clearly states the tool's function, so when to use it is obvious. However, it does not explicitly mention alternatives or exclusion conditions, such as 'use add_ip_address for IPv4.' The context is clear but lacks explicit alternative guidance.

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