Core Features

YAML Workflow Engine

Archon uses YAML to define development workflows, encompassing planning, implementation, validation, code review, and PR creation. This allows for a consistent and repeatable development process.

Source: README
Isolated Workflow Runs

Each workflow run is isolated with its own git worktree, enabling parallel execution without conflicts.

Source: README
Composable Nodes

Workflows can be composed of deterministic nodes (e.g., bash scripts, tests) and AI nodes (e.g., planning, code generation, review), allowing for a flexible and powerful workflow design.

Source: README
Portable Workflows

Workflows are defined in a project's `.archon/workflows/` directory and can be used across different platforms and tools.

Architecture

The architecture of Archon suggests a modular design with clear separation of concerns. It features a command-line interface (CLI) for user interaction, a server component for workflow execution, and a web UI for monitoring and management. The codebase is structured into packages, indicating a focus on code reuse and maintainability. The use of YAML for workflow definition and the integration of AI nodes highlight a microservices-like approach to workflow management.
