Mastering Agent Engineering Workflow with Terminal Tools

Gain actionable insights into a highly productive, professional agent engineering workflow—from terminal setup to managing a crew of AI agents for effective, large-scale task completion.

Short Summary

  • Establish a keyboard-centric workflow using West, tmux, and Neovim for peak flow state.
  • Implement system-level memory files and skills for efficient agent onboarding and knowledge management.
  • Scale work by utilizing specialized tools like Lavish for planning and No Mistakes for automated PR validation.
  • Introduce a First Mate agent (Firstmate) to coordinate multiple crewmates, freeing the captain for strategic oversight.

This guide details a production-tested workflow used for shipping code daily with AI agents. It focuses on fundamental agent engineering concepts, blending specialized terminal tools with core agent configuration principles to maximize productivity and minimize friction. By adopting these techniques, you can transition from managing individual agents to captaining a coordinated, stress-free AI team.

I imagine agentic engineering will be conversational and this paves the way to that future.

The point about the agents not understanding human vs. agent development cost is a gem, thank you!
