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

Annotations indicate this is a mutating, non-idempotent operation, but the description adds no behavioral detail beyond the action itself. It does not disclose potential side effects, duplicate handling, propagation timing, or whether the change can be reverted, which is relevant for a write operation.

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 a single, efficient sentence that front-loads the action and resource, with a helpful parenthetical explanation. Every word earns its place, and there is no redundant or filler content.

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 simple three-parameter creation tool with fully documented schema, the description is mostly adequate. However, it omits usage guidance and behavioral consequences, and with no output schema it does not mention what response or confirmation an agent should expect after invoking the 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?

Schema description coverage is 100%, so the parameters are already documented in the schema. The description adds little semantic value beyond the schema, only framing the operation as adding a host header; it does not deepen understanding of the domain_name, site_name, or host_header relationship.

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 ('Add'), a clear resource ('host header'), and a scope ('to a website on a Linux hosting'). It also clarifies the domain term with a parenthetical definition, making the tool's function unambiguous and distinguishable from sibling operations like set_gzip or subsites_create.

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 given about when to use this tool versus alternatives such as DNS record creation, domain registration, or subsite creation. The description implies its use for adding aliases but does not state prerequisites, exclusions, or when a different Combell tool would be more appropriate.

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