nex_proxy_batch_create

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

With no annotations, the description carries the transparency burden. It discloses that credentials are never returned, which is a useful safety trait, but this is already stated in the schema for password and username. It does not mention partial failure behavior, validation errors, or whether creation is atomic. The added value beyond the schema is modest.

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 description is two sentences with no waste, front-loading the core action ('Create multiple custom proxy resources') and essential requirement ('host and port'). It is efficient and easy to scan.

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 batch operation with nested objects and no output schema, the description is incomplete. It does not explain what happens if some items are invalid, whether creation is all-or-nothing, or that the schema's items field description mentions it 'also accepts proxies or proxyList' (a behavioral nuance not reflected in the description). An agent would be left uncertain about error handling and alternative input shapes.

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?

The schema description coverage is 100% for the only parameter, and the schema provides full documentation for all sub-fields (host, port, protocol, etc.). The description's mention that each item needs host and port repeats the schema's required fields without adding new meaning. Baseline 3 is appropriate when the schema does the heavy lifting.

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 uses a specific verb ('Create'), names the resource ('custom proxy resources'), and specifies the input ('items array') and the per-item requirement ('host and port'). This clearly distinguishes it from siblings like nex_proxy_create (single) and nex_proxy_import.

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 implies batch usage ('multiple') and that each item needs host and port, giving clear context. However, it does not explicitly state when to use this over nex_proxy_create (single) or nex_proxy_import, so it lacks an explicit when-not or alternative mention.

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