nex_account_batch_create

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

No annotations are provided, so the description carries the full burden. It explicitly mentions that secrets are write-only and never returned, which is a valuable behavioral disclosure. However, it does not mention other behaviors such as partial success handling (e.g., if one item fails, do others still create?), idempotency, or rate limits. Given the batch nature and no annotations, more behavioral detail would be expected.

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 only two sentences, both informative and front-loaded with the core action. The first sentence states the purpose, the second adds a critical security caveat. It is concise without being under-specified, though it could make better use of space to mention usage guidelines.

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 creation tool with no output schema, the description covers the essential inputs and the write-only secret behavior, which is enough for a basic call. But it lacks information on what the tool returns (e.g., the created account IDs), error handling for partial failures, and whether the operation is atomic. Given the complexity of a batch operation and the absence of annotations, this is a moderate gap.

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 100%, so the schema already documents all parameters with descriptions. The description adds the crucial note that each item needs platformUrl (reinforcing a required field) and clarifies the write-only nature of secrets. It also mentions that the array accepts 'accounts or accountList' aliases, which is additional semantic value beyond the schema's basic description. However, it does not explain the meaning of other fields like teamId or remark beyond what the schema says, so the baseline is 3 with a slight bump for the alias note.

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 the specific action ('Create multiple platform accounts') and the resource ('from an items array'), clearly distinguishing it from the sibling nex_account_create which is singular. It also highlights that secrets are write-only, which is important context.

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 the batch use case ('multiple platform accounts') and contrasts with the singular nex_account_create by its name. However, it does not explicitly state when to prefer this tool over nex_account_create or provide exclusions or prerequisites. The presence of nex_account_create as a sibling suggests an alternative, but no direct comparison is offered.

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