create_address_subnet

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only states the creation action and return format, without addressing potential side effects, permissions, or constraints (e.g., handling duplicates, overwrite behavior). This is minimal transparency for a mutation tool.

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 well-structured as a docstring with clear sections (Args, Returns, Example). It is comprehensive without being verbose, though the opening line could be slightly more concise. Every sentence adds value.

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's simplicity (4 parameters, output schema defined), the description provides a complete picture: what it does, required inputs, acceptable formats, and expected return values. It lacks edge-case behavior (e.g., duplicate handling) but is sufficient for standard use.

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 0% coverage (no descriptions), but the description compensates fully by explaining each parameter: adom, name, subnet (with example formats), and comment (optional). This adds significant meaning beyond the schema's bare titles.

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 explicitly states 'Create a subnet/network address object,' using a specific verb+resource. Among sibling tools like create_address_fqdn, create_address_host, etc., it clearly distinguishes this tool as specializing in subnet addresses.

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 creating subnet addresses by specifying the subnet parameter format (CIDR or netmask). However, it does not provide explicit guidance on when to use this tool versus alternatives (e.g., for FQDN or host addresses), nor does it mention when not to use it.

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