Only provided fields are changed. `PATCH /v1/environments/global` returns 400 with a pointer to the nested resource endpoints (variables, files, skills, MCPs, warm hooks) — the Global env's metadata cannot be edited directly. Source-backed personal environments cannot change `repository_id`, `repository_set_id`, or `system_prompt`, but may set `personal_preferences`, instructions appended after the inherited system prompt. Returns 409 when an automation still references the environment in a way that blocks the requested change. ## OpenAPI ````yaml /openapi.json patch /v1/environments/{id} openapi: 3.1.0 info: title: Replica API version: 2.0.0 description: >- The Replica API allows you to programmatically manage cloud workspaces for AI agents.
