Hi devs! In this video, I walk through building a coding agent that picks up GitHub issues, writes the fix in a sandboxed Docker environment, and submits a PR - all autonomously, with human approval before anything ships.

You'll see how to wire up a multi-agent workflow (planner → coder → tester) in just a few lines of code using Polos, an open-source (Apache 2.0) runtime for AI agents.

🤖 Why this matters:
AI agents that write code are exciting - until they run unsupervised, modify the wrong files, or push broken PRs. Polos gives agents a sandboxed environment like Docker, E2B etc. to work in and human-in-the-loop approval steps before anything goes live. Your agents do real work. You stay in control.

🛠️ What you'll see:
Trigger a workflow from a GitHub issue
Three agents (planner, coder, tester) collaborating inside a Docker sandbox
Polos manages the sandbox lifecycle - you don't set up Docker containers, manage volumes, or handle cleanup. It's all handled by the runtime
Built-in sandbox tools out of the box: file read/write, bash command execution, web search. No need to build your own tool layer
Human-in-the-loop approvals (Slack based approvals coming soon)
Built-in OTEL tracing and durable execution - if the agent fails, it resumes automatically from where it left off

💡 Perfect if you're building:
Coding agents or AI-powered dev tools
Agents that need to run shell commands, read/write files, or interact with real infrastructure safely
Multi-step agentic workflows with human checkpoints
Any agent you wouldn't trust to run unsupervised
