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

The description states the return value (deleted redirect URL id and deleted flag) and cost (10 tokens), and implies destructive action. However, with no annotations, it lacks explicit warnings about permanence or required permissions.

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?

Four short, front-loaded sentences. No redundancy; each sentence adds meaningful information (action, prerequisite, optional parameter, return, cost).

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 2-parameter delete with output schema, the description covers usage, prerequisites, and return. It could mention that deletion is irreversible, but overall it's adequate.

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%, so parameters are already described. The description reinforces the clerk_instance_id usage but doesn't add new format or constraints beyond the schema.

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 opens with a clear action: 'Remove an allowed redirect URL from a connected Clerk instance.' This specifies the verb, resource, and context, distinguishing it from related tools like clerk.create_redirect_url and clerk.get_redirect_url.

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?

It explicitly instructs to call clerk.get_connected_accounts first and explains how to target a specific connection via clerk_instance_id or default. This provides clear context, though it doesn't mention alternatives or when not to use it.

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