Agent Skills: Install Worktree

Install Worktree

Set up an isolated Git worktree environment for parallel agent execution.

Arguments

• $1: Worktree path (e.g., trees/abc123)
• $2: Backend port (e.g., 9105)
• $3: Frontend port (e.g., 9205)

Instructions

You are setting up an isolated worktree environment for agent parallelization.

Step 1: Validate Arguments

Ensure all three arguments provided:

• Worktree path: $1
• Backend port: $2
• Frontend port: $3

If any missing, report what's needed.

Step 2: Create Port Configuration

Create .ports.env file in the worktree:

BACKEND_PORT=$2
FRONTEND_PORT=$3
VITE_BACKEND_URL=http://localhost:$2

Step 3: Copy Environment Files

Copy main environment file and append port overrides:

# Copy base .env
cp .env $1/.env

# Append port configuration
cat $1/.ports.env >> $1/.env

If there's a server-specific .env, do the same:

cp app/server/.env $1/app/server/.env
cat $1/.ports.env >> $1/app/server/.env

Step 4: Update MCP Configuration

If .mcp.json exists, copy and update paths:

1. Copy .mcp.json to worktree
2. Update any paths to absolute paths for worktree
3. Copy any MCP-related configs (e.g., playwright-mcp-config.json)

Step 5: Install Dependencies

Backend:

cd $1/app/server && uv sync --all-extras

Frontend:

cd $1/app/client && bun install

Step 6: Initialize Database (if applicable)

If there's a database reset script:

cd $1 && ./scripts/reset_db.sh

Step 7: Validate Installation

Run validation checks:

• [ ] Directory exists
• [ ] .ports.env created
• [ ] .env files configured
• [ ] Dependencies installed

Output

Report installation status:

{
  "success": true,
  "worktree_path": "$1",
  "backend_port": $2,
  "frontend_port": $3,
  "steps_completed": ["ports", "env", "deps", "db"]
}

Notes

• Use deterministic port allocation: slot = hash(adw_id) % 15
• Backend ports: 9100-9114
• Frontend ports: 9200-9214
• Always use absolute paths in configurations
