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

The annotations already declare destructiveHint=true, readOnlyHint=false, openWorldHint=true, and idempotentHint=true. The description adds meaningful behavioral context beyond those annotations: both changes require conversation confirmation, confirm:false is a preview, confirm:true repeats identical inputs, and the caller should follow the response envelope's primary nextAction.

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 short and front-loads the core action. Most sentences earn their place by covering the confirmation workflow and preview behavior; 'Operations: set' is slightly redundant with the schema enum, but overall the structure 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?

For a destructive, open-world website visibility mutation with full schema coverage and an output schema, the description is complete enough to call correctly. It covers purpose, confirmation requirements, preview workflow, and how to follow the response, while the schema handles parameter-level details.

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 baseline is 3. The description adds useful meaning beyond the schema by explaining the confirm:false preview followed by confirm:true with identical inputs, which clarifies how the confirm parameter should be used in practice.

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 gives a clear verb and resource: 'Publish a website or take it offline.' This is more specific than the title and distinguishes the action from generic sibling tools like manage_website_domain, but it does not explicitly name or differentiate against those siblings.

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 usage context is implied by the publish/offline action, and the description adds a confirmation workflow with preview mode. However, it does not explicitly say when to use this tool versus alternatives such as manage_website_domain, nor does it state exclusions or prerequisites.

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