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

Annotations already declare destructiveHint=true, idempotentHint=false, and openWorldHint=true, so the agent knows this is an unrecoverable mutation. The description adds the useful consequence that production traffic may change, but omits whether the removal is reversible, whether approval is required, or what happens to traffic routing after deletion.

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?

Two short, front-loaded sentences with no filler; the impact warning follows the action statement. It is efficient, though the extreme brevity is partly why parameter guidance is missing.

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 10-parameter destructive mutation with no output schema and zero schema descriptions, the definition does far too little. It never mentions the required identifiers, the batch limit (maxItems 50), the approval/beon metadata fields, or the return behavior after deletion.

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 0% across 10 parameters, and the description names none of them — not even the required project_id/route_ids. The many beon_* and approval_id fields are completely unexplained in both the schema and the description, leaving no way to know their role.

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+resource ('Remove selected project routes'), which clearly distinguishes it from siblings like vercel_create_project_route and vercel_list_project_routes. It stops short of naming the alternatives explicitly, so it lands at a clear-but-undifferentiated 4.

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 gives no when-to-use or when-not-to-use guidance and does not name any alternative tool or prerequisite. The only contextual hint is the vague 'Production traffic may change', which warns of impact but doesn't help an agent choose this tool over siblings.

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