sophos_create_fqdn_host

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

The description states that the tool creates an object and returns a status dictionary, but does not specify error handling, behavior on duplicate names, or authentication requirements. Annotations provide no additional safety or behavioral hints, so the description carries the full burden and only partially covers it.

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 primary action and resource, followed by a one-line usage context, then structured parameter list, and returns summary. No redundant information.

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, the description covers creation, usage, parameters, and return value adequately. It lacks details on uniqueness constraints or error conditions, but these are minor 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?

The description adds value beyond the input schema by explaining the 'client' parameter (optional instance), which is missing from the schema description. For 'name' and 'fqdn', the description largely repeats schema descriptions, but the overall coverage is improved to near complete.

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 action 'Create' and the resource 'FQDN host object', distinguishing it clearly from sibling tools like sophos_create_ip_host by specifying the object type.

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 provides a specific use case ('when defining domain name target objects for firewall or NAT rules'), giving context for when to use this tool. It does not explicitly exclude alternatives, but the context is clear enough for an AI agent to differentiate.

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