Every AI agent project today is a mess of scattered config, hardcoded prompts, and manual setup steps. There's no standard way to define what an agent is.

Docker solved this for containers with a single Dockerfile. Agentfile does the same for AI agents.

• Reproducible — the same Agentfile produces the same agent every time
• Portable — runs on any machine with Docker or Podman
• Versionable — commit your Agentfile, track how your agent evolves
• Shareable — share your agent like you share a Dockerfile

curl -fsSL https://raw.githubusercontent.com/DeveshB-1/agentfile/main/install.sh | sh

Or with Go:

go install github.com/DeveshB-1/agentfile/cmd/agentfile@latest
