Check if directory pattern in .gitignore

1. Find the worktrees directory.

• Check existing directories using the Bash tool: ls -d .worktrees 2>/dev/null
• If not found, ask me for permission to create a .worktrees directory
• If given permission, create .worktrees.

2. Verify .gitignore before creating a worktree using the Bash tool:

# Check if directory pattern in .gitignore
grep -q "^\.worktrees/$" .gitignore || grep -q "^worktrees/$" .gitignore

• If not found, add the appropriate line to the .gitignore immediately.

3. Create the worktree

• Come up with a good branch name based on the request.
• Create the worktree with the Bash tool: `git worktree add ".worktrees/$BRANCH_NAME" -b "$BRANCH_NAME"
• cd into the newly created path with the Bash tool: cd $path

4. Auto-detect and run project setup.

# Node.js
if [ -f package.json ]; then npm install; fi

# Rust
if [ -f Cargo.toml ]; then cargo build; fi

# Python
if [ -f requirements.txt ]; then pip install -r requirements.txt; fi
if [ -f pyproject.toml ]; then poetry install; fi

# Go
if [ -f go.mod ]; then go mod download; fi
