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

With no annotations present, the description carries full responsibility for behavioral disclosure, and it delivers. It reveals side effects: publish includes a $1 USDC charge, takes an action that makes content live, and can perform a CNAME binding. It explains error-prone behaviors: retry claim on PRICE_COMPUTE_FAILED without fear of double charge, but do not retry payment if settlement failed, and use the slug worldsite.workers.dev format.

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?

Every sentence carries meaningful instruction or a constraint, so the text is not padded. However, it is a long run-on procedure in a single block rather than a crisp structured format; adding slight sectioning could help an agent parse the sequence faster. It is front-loaded with the most critical safety instruction, which earns partial credit for structure.

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 high complexity of this workflow, zero annotations, and no output schema, the description is remarkably complete. It covers preconditions, step sequence, required user interactions, error cases, retry behavior, URL formatting, optional host labels, the denial cases. An agent could plausibly execute the publish flow and know how to handle the major failure modes without asking for more documentation.

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 zero parameters, so the baseline is 4: no parameter documentation is needed. The description does not incorrectly introduce parameters; it refers to upstream values like putUrl, dropUrl, UUID, slug, and previewUrl in the context of the workflow, which is appropriate for a tool that orchestrates other processes.

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 explicitly states the tool's purpose as 'Publish a website' and then immediately enumerates the exact multi-step workflow (upload, inspect, preview, claim, hostname). This clearly distinguishes publish_website as the orchestrating action from sibling tools like claim, inspect, preview_status, and upload_url, which are individual steps in the flow.

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 concrete, imperative guidance for when and how to act: always ask the human about cost and legal issues first, put content via upload_url and PUT putUrl, use inspect to get the UUID, use preview_status solely to read remaining time, and ask which slug before claiming. It also gives explicit do-nots, such as never inspecting just for the clock, never retrying after settlement failure, and never putting the zip in chat.

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