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

With no annotations provided, the description fully covers behavioral traits: asynchronous generation, returns URL and ID, editing requires going to Hostinger Horizons interface, and detailed technology stack constraints. This leaves no ambiguity about tool behavior.

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 excessively long, largely due to the extensive technology stack constraints. While valuable, this information could be moved to separate documentation. The description is not concise and includes many lines that could be summarized.

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 complexity and lack of output schema, the description covers all necessary aspects: purpose, usage, behavior, parameter semantics, post-invocation actions, and error handling. It leaves no significant gaps.

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 input schema has 100% description coverage for its single parameter (message), which is already well-documented. The description adds no further detail about the parameter beyond what is in the schema, so baseline 3 is appropriate.

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 'Create new Hostinger Horizons website from the given message' and specifies when to use it ('when user asks you to create a website, landing page, blog or any other type of application'). This distinguishes it from sibling tools like hosting_createWebsiteV1.

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 explicit guidance on when to use (user requests website creation), what to do after invocation (exact reply format, provide URL, do not write code), and how to handle failures (clear explanation, no code generation). This is comprehensive and actionable.

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