  title: Replica API
  version: 2.0.0
  description: >-
    The Replica API allows you to programmatically manage cloud workspaces for
    AI agents. Use this API to manage environments (the org-scoped primitive
    workspaces are created from — including variables, files, skills, MCPs, warm
    hooks, start hooks, and warm pools), create and manage replicas, send
    messages, manage chats, stream events, read connected repositories and
    repository sets, and configure automations.

    description: >-
      Manage environments — the primitive that workspaces are created from.
      Variables, files, skills, MCPs, warm-hooks, and warm-pools are all scoped
      to an environment. Every organization has a singleton Global environment
      whose values apply to every workspace. Personal environments are scoped to
      the authenticated user and can be standalone or source-backed by a team
      environment.
  - name: Repository
    description: >-
      Read repositories and repository sets connected to your organization.
      Repositories are the underlying GitHub-connection layer; bind them to an
      environment to use them in workspaces.
  - name: Replica
    description: >-
      Manage replicas (workspaces) for AI agents. Workspace creation with `POST
      /v1/replica` accepts API keys and workspace engine-secret authentication.
      Other Replica operations also accept logged-in user JWTs from first-party
      clients.

    description: >-
      Read workspace media and obtain short-lived download or inline preview
      URLs
  - name: Analytics
    description: >-
      Read aggregated activity and usage metrics for your organization: compute
      minutes, workspaces created by source, and pull request throughput over a
      time range.
  - name: Presence
    description: >-
      Read and report ephemeral member presence: who is online, where they are
      (environment or workspace), and whether they are typing. Presence is
      backed by short-lived keys rather than the database and broadcast to other
      members over the events stream.
  - name: Plugins
    description: >-
      Install and manage native and Composio-backed workspace plugins. A plugin
      installs for a single environment, for the whole organization (which uses
      the Global environment), or for one member personally. A workspace uses
      the most specific installation available: personal, then its own
      environment, then the environment it was branched from, then Global.
