Rollback Cloudflare Domain

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

With destructiveHint=true already declaring the write, the description adds substantial non-obvious context: the Cloudflare zone is deliberately left in place (what is NOT destroyed), user confirmation is required before changing authoritative DNS, and the exact failure conditions. This is exactly the extra behavioral detail annotations cannot convey.

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?

Three tightly packed sentences with the undo action, the safety caveat, the non-deletion guarantee, and failure modes front-loaded. No sentence is filler.

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 nameserver mutation with no output schema, the description covers the side effects, the deliberate non-action, the authoritativeness of the change, the required confirmation, and failure conditions. An agent has everything needed to call it correctly.

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% and the two parameters are self-described, so the schema already carries the burden. The description mentions the domain implicitly but adds no syntax or usage detail for domain or dry_run; baseline 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?

"UNDO a completed Cloudflare move: point the domain's nameservers back at Porkbun, restoring the DNS Porkbun still holds" gives a precise verb, resource, and mechanism. It is clearly distinguishable from siblings like retry_cloudflare_domain, disconnect_cloudflare, and connect_domains_to_cloudflare.

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 presents explicit preconditions ("confirm with the user first") and three concrete cases where the call will fail (never moved, already back on Porkbun, currently in progress), which effectively tells the agent when not to invoke it. It does not, however, name a sibling alternative for those cases, so it stops short of full routing guidance.

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