# Cursor: development environments for cloud agents with Dockerfile-as-config and governance

> Cursor introduced configurable development environments for cloud agents, supporting multi-repo setups, Dockerfile-based configuration with build secrets, and layer caching (70% faster rebuilds on cache hits). Environments have version history with rollback, admin-restricted rollback permissions, audit logs, and per-environment egress/secret scoping. Agent-led setup includes credential validation and graceful fallback to a base image on failure.

## What changed


- Multi-repo environments: single environment with all repositories needed, reusable across sessions
- Dockerfile-based config with build secrets (scoped to build step, not passed to agent runtime)
- Layer caching so only changed layers rebuild; cache-hit builds run ~70% faster
- Agent-led setup: asks questions, flags missing credentials, validates environment
- Shows environment version; defaults to base image with warnings on config failure
- Version history with rollback; admins can restrict rollback to admins only
- Audit log for all environment changes
- Per-environment egress and secret scoping
