A Human-In-The-Loop AI Factory CLI. wralph wraps a coding agent and CI to autonomously complete software objectives—planning, executing, creating PRs, and iterating on CI failures—while keeping a human in the loop.

wralph uses the "Ralph Wiggum" technique: point an AI agent at an issue, let it plan and code, then iterate on CI failures until the build passes. What sets it apart:

• Git worktrees isolate each issue, so multiple instances can run on the same repo without interference
• Remote CI evaluation (default: CircleCI) means parallel instances never conflict
• Pluggable adapters for objective sources, CI systems, and AI agents

brew tap niborg/homebrew-wralph
brew install wralph

For development:

git clone https://github.com/niborg/wralph
cd wralph
bundle install

# Initialize in your repo
wralph init

# Edit .wralph/secrets.yaml with your CI API token
# Edit .wralph/config.yaml to configure adapters

# Plan and execute an issue (creates PR, monitors CI, auto-fixes failures)
wralph plan 123

# After PR review, address feedback
wralph feedback 123

# Clean up after merge
wralph remove 123

Running wralph init creates a .wralph/ directory:

.wralph/
├── config.yaml    # Adapter and prompt configuration
├── secrets.yaml   # CI API token (git-ignored)
├── plans/         # Generated plans
└── objectives/    # Downloaded issues

  branch_name: "issue-#{identifier}"   # Branch naming template

Set source: custom and provide class_name for any adapter. Place the implementation file in .wralph/ using snake_case naming (e.g., class_name: MyAdapter → .wralph/my_adapter.rb).

• Plans are saved to .wralph/plans/plan_<issue>.md for reference
• CI failures are logged to tmp/ with iteration numbers
• CI monitoring polls every 30s, with a 1-hour timeout
• Failed CI triggers up to 10 automatic fix-and-retry cycles
• Feedback input uses multi-line mode (press Enter 3 times to submit)
• The agent is instructed to push to CI rather than run tests locally
