Review first — review before installing

Open the source and read safety notes before installing.

Safety notes

  • Review YAML workflow nodes before running bash or git operations in isolated worktrees.
  • Self-hosted deployments require patching and backup like other internal developer platforms.
  • Archon telemetry is documented in the repository; review before enterprise rollout.
  • Workflow runs can create branches and pull requests; scope repository permissions narrowly.

Privacy notes

  • Workflow execution data stays in your Archon deployment, git worktrees, and connected repositories.
  • AI assistant clients may send prompts and tool output to model providers per client privacy settings.
  • Shared workflow repos may expose internal process details; restrict repository access accordingly.
  • Review Archon repository privacy and telemetry sections before processing sensitive codebases.

Prerequisites

  • Local environment capable of building the Archon repository from source.
  • Git access to clone https://github.com/coleam00/Archon.
  • Target project repository where workflow files will be stored.

## Overview

Archon is an open-source workflow engine for AI coding agents. The project README
describes encoding development processes as YAML workflows with planning, implementation,
validation, review, and pull request phases so agent runs follow a deterministic structure.

Teams commit workflows under `.archon/workflows/` and run them from Claude Code, the
Archon CLI, or connected platform adapters.

## Features

- YAML-defined development workflows with deterministic node sequencing.
- Isolated git worktrees per workflow run for parallel agent work.
- Mix of deterministic bash or test nodes and AI planning or review nodes.
- Default workflows for issue fixes, idea-to-PR flows, PR review, and validation.
- Repository setup wizard and skills copied into target projects per official README.

## Use Cases

- Standardize bug-fix and feature workflows across Claude Code projects.
- Run repeatable validate-and-PR pipelines with human approval gates in YAML.
- Encode team code review or conflict-resolution processes as reusable workflows.
- Compare structured Archon runs against ad hoc agent chat sessions.

## Source Notes

Verified against the public Archon repository README on **2026-06-16**:

- README describes Archon as a workflow engine for AI coding agents with YAML workflows
  covering planning, implementation, validation, code review, and PR creation.
- Official getting started guidance recommends cloning the GitHub repository and using
  the guided setup wizard rather than undocumented install paths.
- README documents default workflows, isolated worktrees, and platform adapters including
  CLI and web UI integration with Claude Code.

Safety notes✓Review YAML workflow nodes before running bash or git operations in isolated worktrees. Self-hosted deployments require patching and backup like other internal developer platforms. Archon telemetry is documented in the repository; review before enterprise rollout. Workflow runs can create branches and pull requests; scope repository permissions narrowly.— missing✓CodeLayer orchestrates AI coding agents that edit files and run commands in your repositories, so it inherits the execution risks of the underlying Claude Code agent. MultiClaude runs multiple Claude Code sessions in parallel across git worktrees; review changes per worktree before merging to avoid conflicting or unreviewed edits. Remote cloud workers can run agent sessions on external infrastructure; understand where code executes before enabling them. Scaling agent workflows to a whole team increases the blast radius of automated edits, so keep human review and branch protections in place.✓Codex CLI runs as a local agent that can edit files and execute commands on your machine. It supports configurable sandbox and approval modes; keep approvals enabled and review proposed actions before allowing them. Lowering approval or sandbox restrictions lets the agent act more autonomously, increasing the risk of unintended changes. Review generated code and commands before running them against important repositories or systems.
Privacy notes✓Workflow execution data stays in your Archon deployment, git worktrees, and connected repositories. AI assistant clients may send prompts and tool output to model providers per client privacy settings. Shared workflow repos may expose internal process details; restrict repository access accordingly. Review Archon repository privacy and telemetry sections before processing sensitive codebases.— missing✓Because it builds on Claude Code, repository code and context are sent to Anthropic's API to power the agent. Remote cloud workers process your code and context on external infrastructure; review the provider's terms before sending private code. Any API keys or credentials used by Claude Code and CodeLayer should be stored as secrets, not committed to source control. Team and context-engineering features can share prompts, context, and workflow data across collaborators, so avoid placing secrets in shared context.✓Code and prompts are sent to OpenAI to power the agent under your ChatGPT plan or API key. Data handling follows OpenAI's policies for the plan or API you authenticate with; review them before processing sensitive code. API keys and account credentials should be stored securely and never committed to source control.
Prerequisites
  • Local environment capable of building the Archon repository from source.
  • Git access to clone https://github.com/coleam00/Archon.
  • Target project repository where workflow files will be stored.
— none listed
  • Claude Code, since CodeLayer is built on top of it and orchestrates Claude Code sessions.
  • An Anthropic account or API access for the underlying Claude Code agent.
  • A recent CodeLayer build from the project's GitHub releases or the waitlist for early access.
  • Git, since parallel-session workflows rely on worktrees.
  • A ChatGPT plan (Plus, Pro, Business, Edu, or Enterprise) for plan-based sign-in, or an OpenAI API key.
  • Node.js and npm for the npm install, or Homebrew for the cask install.
  • A terminal on macOS, Linux, or Windows.
