Create a cloud server

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

With no annotations, the description covers billing and the need for confirm, but omits details like start_after_create behavior (e.g., server starts by default), return format, or asynchronous nature. The provided traits are useful but incomplete.

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?

Two sentences, no fluff, and front-loaded with the core action. Could be slightly restructured for clarity but is efficient.

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 11 parameters and no output schema, the description is incomplete: it fails to mention required parameters (name, server_type, image) as mandatory and does not address return values or location. The phrase 'Optionally attach' might mislead about required fields.

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 coverage is 100% (all 11 parameters have descriptions). The description merely lists optional attachments without adding new semantic details, so it does not enhance understanding beyond the schema.

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 specific action: 'Create a Hetzner Cloud server.' It uses a specific verb and resource, distinguishing it from sibling tools like cloud_list_servers and cloud_delete_server. No ambiguity.

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 the tool is for creating servers but does not explicitly state when to use it vs. alternatives, nor does it provide exclusions or prerequisites beyond requiring confirm=true.

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