Key takeaways include starting with one agent and scaling up when idle, using Red/Green TDD to dramatically improve agent output quality, treating the agent like a new colleague by providing context and documentation links, using dedicated terminals (Warp/Ghostty) instead of VS Code's integrated terminal, leveraging git worktrees for parallel work in a single repo, and skipping permission prompts via auto mode to reduce friction. The author found that TDD acted as a specification, guardrail, and verification loop, enabling the agent to self-correct without human intervention. ## Full article daily.dev links to this article rather than hosting it.
