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

Annotations already declare readOnlyHint=false, destructiveHint=true, openWorldHint=true, and idempotentHint=false, so the safety profile is largely covered. The description adds the useful approval requirement in BEON PASS, but it never explains what 'verify' actually does (DNS check, retry behavior, external phone-home), so it leaves a meaningful gap.

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 sentences with no filler, and the core purpose is front-loaded ahead of the approval constraint. Efficient, though the extreme brevity is part of why other dimensions are thin.

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, open-world tool with no output schema and no schema descriptions, the definition is far too thin — it omits what verification entails, the role of the BEON routing parameters, and any failure/return expectations.

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?

With 10 parameters and 0% schema description coverage, the schema documents none of them, so the description carries the full burden — and it only hints at 'approval' without clarifying approval_id, beon_* routing fields, or the team_id/project_id/domain relationship. It does not compensate for the coverage gap.

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 ('Verify ownership of a project domain'), which cleanly separates it from siblings like vercel_add_project_domain, vercel_list_project_domains, and vercel_remove_project_domain. It stops short of explicitly naming those alternatives, so it lands at 4 rather than 5.

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 states a precondition ('Requires exact user approval in BEON PASS'), which is real usage context, but gives no guidance on when this tool is appropriate versus the add/list/remove domain siblings, nor what state the domain must be in first. Implied usage only.

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