erk

erk is a CLI tool for plan-oriented agentic engineering: create implementation plans with AI, save them to GitHub, execute them in isolated worktrees, and ship code via automated PR workflows.

Read the Documentation for complete guides, tutorials, and reference. (source)

For the philosophy and design principles behind erk, see The TAO of erk.

Quick Start

# Install prerequisites: python 3.10+, claude, uv, gt, gh

The Workflow

The primary workflow: plan → save → implement → ship. Often completes without touching an IDE.

claude
# → develop plan → save to GitHub issue #42

# 2. Implement
erk implement 42

# 3. Submit PR
erk pr submit

# 4. Address feedback
/erk:pr-address

# 5. Land
