Input

$ARGUMENTS

If no arguments provided, ask for:

1. •Project idea — description of what to build
2. •Tech stack — preferred technologies (or "auto" to let the agent decide)
3. •Repository name — name for the GitHub repo

Full Pipeline

Stage 1: Plan

• •Generate plan.md with phases, features, and file structure
• •Generate issues.json with all issues ordered by dependency

Stage 2: Repository Setup

• •Create GitHub repo (private)
• •Generate project scaffolding
• •Create staging branch from main

Stage 3: Implement (per phase)

For each phase, for each issue:

1. •Create GitHub issue with formatted body
2. •Create feature branch from staging: feature/issue-{N}-{slug}
3. •Implement the code (delegate to implementer agent)
4. •Commit, push, create PR targeting staging
5. •Review PR (delegate to reviewer agent)
6. •Execute test plan with fix-retry loop (delegate to tester agent)
7. •Squash-merge PR into staging
8. •Close the issue

Stage 4: Phase Merge

After each phase completes:

• •Create PR from staging to main
• •Merge (non-squash, preserves history)
• •Sync staging with main

Stage 5: Completion

Report the final GitHub repository URL.

Branching Strategy

main ← staging ← feature/issue-{N}-{slug}

Resumability

Before each step, check if it's already done (via git/GitHub state). Skip completed work. Resume from the exact point of interruption.
