remove_domain_from_whitelist

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

Annotations already provide destructiveHint=true. The description reinforces with 'DESTRUCTIVE · deletes data' and 'Deletes a record.' It adds the HTTP method and confirmation instruction, providing useful behavioral context beyond annotations.

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 relatively concise with a header, primary statement, and action note. However, the final sentence is redundant ('Remove a domain from the site tracking whitelist'), making it slightly repetitive. Still, it is well-structured.

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 simple deletion tool with one parameter and no output schema, the description is complete. It specifies the action, resource, parameter, destructive nature, and user confirmation requirement, leaving no gaps.

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 description does not add meaning beyond the input schema, which already describes the 'name' parameter as 'The domain name to remove from the whitelist'. With 100% schema coverage, baseline score of 3 is appropriate.

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 action 'Remove domain from whitelist' and specifies the resource 'Site Tracking Domains'. It distinguishes from siblings like 'add_domain_to_whitelist' and 'list_all_whitelisted_domains'.

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 includes a usage note: 'Confirm with the user before calling.' It implies this is for removal only. While it doesn't explicitly state when not to use, the destructive hint and context provide adequate guidance.

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