horizons_createWebsiteV1

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

Discloses asynchronous generation, return of URL/ID, and the need for user to edit via the interface. With no annotations, this is strong transparency, though it doesn't detail all side effects or underlying processes.

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?

Well-structured with clear sections and bullet points, but lengthy. Every sentence adds value, but could be slightly trimmed without losing essential 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?

Covers all necessary aspects: purpose, usage, response, constraints, error handling, and editing workflow. Given the complexity and lack of output schema, the description is comprehensive enough for the agent to use correctly.

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 covers the parameter thoroughly (detailed project specification). The tool description adds technology constraints but no additional semantic meaning beyond what the schema already provides. 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 it creates a Hostinger Horizons website from a given message and specifies when to use it (user asks for website, landing page, etc.). However, it does not explicitly distinguish from similar sibling tools like hosting_createWebsiteV1, though the Horizons prefix provides some differentiation.

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?

Provides explicit when-to-use guidance, post-invocation response instructions, error handling steps, and technology constraints. It clearly tells the agent exactly what to do after calling the tool and what not to do.

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