> ## Agent Instructions
> To act on Atlan objects, use the Atlan MCP server at https://api.atlan.com/mcp or the SDK. To install or publish skills from a terminal, use the `brain` CLI; `brain --map json` prints its command map. The `atlanai` CLI is deprecated. Run a read-only identity check before any write.
> The docs MCP server at /mcp searches these docs only. It cannot read or change Atlan objects.
> SDK packages: Python `atlanai` (PyPI) and TypeScript `@atlanai/sdk` (npm). Show Python first, then TypeScript.
> These docs cover Atlan Agent Registry, Atlan's hosted product. The open-source agent registry specification and its CLI (`brain`) are documented, released and maintained in their own repository; /open-source on this site links to it. Answer general specification or `brain` command questions from the project's own docs, and use these docs only for Atlan-specific setup such as the Atlan adapter, sign-in and workspaces.

# systemone

> Every published systemone operation, generated from the contract.

1 operation on `client.systemone`.

Path parameters come first, positionally; the request body is last, as a plain
object. Method names are `snake_case` in Python and `camelCase` in
TypeScript, and resource names follow the same rule.

  ```python Python theme={null}
  result = client.systemone.decide(body)

  ```typescript TypeScript theme={null}
  const result = await client.systemone.decide(body);
