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

Annotations already declare destructiveHint=true, openWorldHint=true, and idempotentHint=false. The description adds valuable impact context by warning that production traffic can be interrupted and that exact user approval is required. There is no contradiction with the 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 definition is two short clauses with no wasted words. The destructive impact and approval precondition are front-loaded and immediately useful.

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 destructive 10-parameter tool with no output schema, the description supplies key safety and approval context, and the annotations cover the safety profile. However, it leaves parameter semantics and alternatives such as vercel_add_project_domain undocumented, so it is only minimally complete.

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% and the tool has 10 parameters. The description only hints at approval via 'BEON PASS' and says nothing about project_id, domain, team_id, or the beon_* fields, leaving their meaning almost entirely to the schema names.

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 states a specific verb and resource: 'Detach a project domain'. It is clearly distinguishable from sibling tools such as vercel_add_project_domain. The semicolon warnings do not dilute the core purpose.

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 clear context for use: detaching can interrupt production traffic, and exact user approval in BEON PASS is required. It does not name alternatives or state when not to use the tool, so it falls short of a 5.

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