List Cloudflare Inventory

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

Annotations already declare readOnly, idempotent, non-destructive and openWorld. The description adds non-obvious context beyond that: it works even when the Cloudflare account isn't connected yet, so planning is possible before authorization. That is the key behavioral trait an agent needs and it's disclosed here.

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 tight sentences, front-loaded with what it lists, then return semantics, then the pre-queue recommendation. Every sentence carries information an agent would otherwise have to guess.

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?

There is no output schema, so the description has to cover return shape, and it does: it enumerates the possible state values and explains that each carries a human-readable reason with examples. Combined with the connected-account caveat, an agent has everything needed to call and interpret this tool.

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?

Zero parameters, so the baseline of 4 applies; there is nothing the description could add on this dimension.

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 and resource ('List every domain in the account') and immediately narrows the scope to Cloudflare eligibility, which separates it from list_domains and get_cloudflare_domain_status. The enumerated state values make the payload concrete.

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?

Explicitly says to read this BEFORE queueing so the agent can tell the user what will move and what won't, which is genuine when-to-use guidance tied to a sibling workflow (connect/queue tooling). It stops short of naming the alternative tools outright, leaving some inference.

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