What you'll learn
Create isolated workspaces
Use ephemeral Git worktrees to give each agent task its own working environment.
Define sandbox boundaries
Understand what an agent should and should not be allowed to access during execution.
Build the harness
Connect task execution, workspace isolation, and agent boundaries into a repeatable workflow.
Protect the main workspace
Keep background agent work separated from active development.
Why this topic matters
A coding agent needs more than access to a repository. It needs a controlled environment where it can work without interfering with other tasks or the developer's workspace. You'll build the execution layer around ephemeral Git worktrees and sandbox boundaries. Part 2 of 4 in the Software Factory series.
