git-hat 🧢

Wear different hats by switching git branches.

A pi extension that maps git branches to roles (planner, implementor, reviewer, admin) and enforces role-based permissions.

Install

pi install npm:@senomas/pi-git-hat

No other dependencies needed. On first startup, role prompts and a default roles.json auto-seed into your project's .pi/.

Features

• Role-based branch switching — /hat TUI to pick branches grouped by role
• Permission enforcement — each role can only write to certain paths
• Tool enforcement — per-role allow/block rules for commands (docs)
• System prompt injection — role instructions injected automatically per session
• Ancestry checking — /hatt validates branch parent chain before work
• Auto-seeding — role prompts copied from bundled roles/ to project .pi/ on first use

Quick Start

# Install
pi install npm:@senomas/pi-git-hat

# Create a roles.json
mkdir -p .pi
cat > .pi/roles.json << 'EOF'
{
  "roles": {
    "planner":      { "pattern": "^plan",      "description": "Plan work" },
    "implementor":  { "pattern": "^feat",      "description": "Implement features" },
    "reviewer":     { "pattern": "^review",    "description": "Review implementations" },
    "admin":        { "pattern": "^(main|master)$", "description": "Configuration" }
  }
}
EOF

# Start pi — role prompts auto-seed into .pi/
