About Archon
Archon is an open source workflow engine for AI coding agents, written in TypeScript and released under the MIT license. It lives in the AI coding ecosystem, alongside tools such as Claude Code, and is distributed through the Bun runtime and the GitHub CLI.

Workflows are stored in a .archon/workflows/ directory and committed to the repository, so the same definition can be invoked from the CLI, a web UI, Slack, Telegram, or GitHub.…
