System prompts are listed in the order they're combined. Values from environments you can't read are blanked and flagged `masked`. ## OpenAPI ````yaml /openapi.json get /v1/environments/{environment_id}/effective openapi: 3.1.0 info: title: Replicas API version: 2.0.0 description: >- Create and control workspaces, and manage the environments, automations, and learnings they run with. servers: - url: https://api.replicas.dev description: Production API security: - apiKey: [] tags: - name: Replica description: >- A replica is a Replicas workspace: a cloud sandbox where a coding agent works on your repositories. - name: Chats description: Manage the agent chats inside a replica. - name: Message queue description: Messages waiting for the agent to finish its turn. - name: Commands and terminals description: Run commands and open shells in a replica. - name: Pull requests description: Inspect and act on pull requests a replica opened. - name: Previews description: Public URLs for ports in a replica. - name: Canvas description: Plans, reports, and other files agents produce. - name: Sharing description: Add replicas to members' Shared view. - name: Environments description: >- Environments define what a workspace starts with.
