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

Annotations cover the safety profile (readOnly false, openWorld true, destructive false), and the description adds real behavioral context: files go live immediately at <businessId>.webzum.com with SSL, no build step, no hosting account. It stops short of stating whether sites can be updated or deleted later.

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 core purpose and the host_file/host_zip/build_website routing are front-loaded and useful, but the 'Why it matters' paragraph is persuasive marketing rather than operational guidance and does not help the agent invoke the tool.

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?

No output schema exists, and the description compensates by naming the returned businessId and live URL. Combined with the immediate-publish behavior and file-addition path, an agent has nearly everything needed; only lifecycle/update behavior is unaddressed.

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 schema already documents all four parameters including the siteType enum. The description's prose list (tool, dashboard, prototype, demo, portfolio, landing page) hints at site types but adds no syntax or default detail beyond the schema. Baseline 3.

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?

States a specific verb and resource ('Creates a hosted site on WebZum') plus the return value (businessId and live URL). It explicitly distinguishes itself from the sibling build_website, which is what an agent needs to route correctly.

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?

Gives explicit when-to-use ('content someone wants live, shareable or running on their phone') and when-not, naming build_website as the alternative for a real business site. It also explains the follow-up path via host_file and host_zip.

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