Update VWO custom widgets in bulk

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

The description discloses important behavioral traits beyond annotations: widgets may be linked to live campaigns so edits can affect visitors, and the endpoint is inferred and unconfirmed. This adds significant context that annotations (destructiveHint=true, openWorldHint=true) do not fully capture, helping the agent understand risks.

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 concise with two sentences plus a caution. It is well-structured and front-loaded with purpose. However, the caution is somewhat lengthy and could be more succinct.

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 tool's complexity (bulk update, live campaigns, inferred endpoint, no output schema), the description appropriately covers key risks and usage caveats. It lacks information about return values or error handling, but that is partially excused by missing output schema.

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%, and the description adds meaning for the body parameter (explaining it's a bulk payload with unclear schema and pointing to external docs) and for accountId/workspaceName (not to guess id). This adds value beyond the schema descriptions, though the schema already provides good baseline.

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 title and description clearly state the tool's purpose: 'Update VWO custom widgets in bulk' and 'Change several custom widgets in one request.' This distinguishes it from sibling tools like vwo_update_custom_widget (single) and vwo_create_custom_widgets (create).

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 context about potential impact on live campaigns and advises caution, including verifying the first call due to an inferred endpoint. It does not explicitly state when not to use this tool or list alternatives, but the caution and bulk nature imply appropriate usage.

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