neon.branches.create

Create a Neon branch (fire-and-forget)

Creates a Neon branch (fire-and-forget).

Issues POST /projects/{neon_project_id}/branches against the Neon REST API (https://console.neon.tech/api/v2). Neon returns an operations[] array whose entries must reach finished, but this atomic does NOT poll — it returns immediately with the new branch id and the create operation id. The caller (orchestration C-03) composes neon.operations.wait (A-22) to block until the operation finishes. This keeps every base atomic uniformly 3-state.

UUID-only surface rule: connection_uuid is our identifying handle; Neon's own ids stay on the neon_<x>_id surface (neon_project_id, neon_branch_id, neon_operation_id). parent_id is a Neon branch id passed straight through.

Inputs:

• connection_uuid: Cloud connection UUID for Neon credentials (required).
• neon_project_id: Neon project id to create the branch in (required).
• name: Optional branch name; Neon auto-names if omitted.
• parent_id: Optional Neon branch id to branch from; defaults to the primary.

Outputs (terminal state_data):

• neon_project_id: str — pass-through project id.
• neon_branch_id: str — id of the newly created branch.
• name: str — confirmed branch name.
• is_primary: bool — whether the branch is the project's primary branch.
• parent_id: str — Neon id of the parent branch.
• neon_operation_id: str — id of the create operation; feed to A-22.
• provider_metadata: dict — raw Neon branch object.

Plugin required: context.get_plugin("neon") must expose .api_token.
