description	[Git] Create isolated git worktree for parallel development Use when this capability is needed.

[IMPORTANT] Use TaskCreate to break ALL work into small tasks BEFORE starting — including tasks for each file read. This prevents context loss from long files. For simple tasks, AI MUST ATTENTION ask user whether to skip.

Quick Summary

Goal: Create isolated git worktrees for parallel feature development with automatic branch naming and env file setup.

Workflow:

1. Get Repo Info — Run worktree.cjs info to detect repo type, base branch, env files
2. Detect Prefix — Infer branch prefix from keywords (fix, feat, refactor, docs, etc.)
3. Convert Slug — Transform description to kebab-case slug (max 50 chars)
4. Execute — Run worktree.cjs create with project, slug, prefix, and env files

Key Rules:

• For monorepos, ask user which project if not specified
• Always ask which env files to copy via AskUserQuestion
• Handle error codes (BRANCH_CHECKED_OUT, WORKTREE_EXISTS, etc.) gracefully

Be skeptical. Apply critical thinking, sequential thinking. Every claim needs traced proof, confidence percentages (Idea should be more than 80%).

Create an isolated git worktree for parallel feature development.

Workflow

Step 1: Get Repository Info

node .claude/scripts/worktree.cjs info --json

Response fields:

• repoType: "monorepo" or "standalone"
• baseBranch: detected base branch
• projects: array of {name, path} for monorepo
• envFiles: array of .env* files found
• dirtyState: boolean

Step 2: Gather Info via AskUserQuestion

Detect branch prefix from user's description:

• Keywords "fix", "bug", "error", "issue" → prefix = fix
• Keywords "refactor", "restructure", "rewrite" → prefix = refactor
• Keywords "docs", "documentation", "readme" → prefix = docs
• Keywords "test", "spec", "coverage" → prefix = test
• Keywords "chore", "cleanup", "deps" → prefix = chore
• Keywords "perf", "performance", "optimize" → prefix = perf
• Everything else → prefix = feat

For MONOREPO: Use AskUserQuestion if project not specified:

// If user said "/worktree add auth" but multiple projects exist
AskUserQuestion({
    questions: [
        {
            header: 'Project',
            question: 'Which project should the worktree be created for?',
            options: projects.map(p => ({ label: p.name, description: p.path })),
            multiSelect: false
        }
    ]
});

For env files: Always ask which to copy:

AskUserQuestion({
    questions: [
        {
            header: 'Env files',
            question: 'Which environment files should be copied to the worktree?',
            options: envFiles.map(f => ({ label: f, description: 'Copy to worktree' })),
            multiSelect: true
        }
    ]
});

Step 3: Convert Description to Slug

• "add authentication system" → add-auth
• "fix login bug" → login-bug
• Remove filler words, kebab-case, max 50 chars

Step 4: Execute Command

Monorepo:

node .claude/scripts/worktree.cjs create "<PROJECT>" "<SLUG>" --prefix <TYPE> --env "<FILES>"

Standalone:

node .claude/scripts/worktree.cjs create "<SLUG>" --prefix <TYPE> --env "<FILES>"

Options:

• --prefix - Branch type: feat|fix|refactor|docs|test|chore|perf
• --env - Comma-separated .env files to copy
• --json - Output JSON for parsing
• --dry-run - Preview without executing

Commands

Command	Usage	Description
create	create [project] <feature>	Create new worktree
remove	remove <name-or-path>	Remove worktree and branch
info	info	Get repo info
list	list	List existing worktrees

Error Codes

Code	Meaning	Action
MISSING_ARGS	Missing project/feature for monorepo	Ask for both
MISSING_FEATURE	No feature name (standalone)	Ask for feature
PROJECT_NOT_FOUND	Project not in .gitmodules	Show available projects
MULTIPLE_PROJECTS_MATCH	Ambiguous project name	Use AskUserQuestion
MULTIPLE_WORKTREES_MATCH	Ambiguous worktree for remove	Use AskUserQuestion
BRANCH_CHECKED_OUT	Branch in use elsewhere	Suggest different name
WORKTREE_EXISTS	Path already exists	Suggest use or remove
WORKTREE_CREATE_FAILED	Git command failed	Show git error
WORKTREE_REMOVE_FAILED	Cannot remove worktree	Check uncommitted changes

Example Session

User: /worktree fix the login validation bug

Claude: [Runs: node .claude/scripts/worktree.cjs info --json]
        [Detects: standalone repo, envFiles: [".env.example"]]
        [Detects prefix from "fix" keyword: fix]
        [Converts slug: "login-validation-bug"]

Claude: [Uses AskUserQuestion for env files]
        "Which environment files should be copied?"
        Options: .env.example

User: .env.example

Claude: [Runs: node .claude/scripts/worktree.cjs create "login-validation-bug" --prefix fix --env ".env.example"]

Output: Worktree created at ../worktrees/myrepo-login-validation-bug
        Branch: fix/login-validation-bug

Closing Reminders

• IMPORTANT MUST ATTENTION break work into small todo tasks using TaskCreate BEFORE starting
• IMPORTANT MUST ATTENTION search codebase for 3+ similar patterns before creating new code
• IMPORTANT MUST ATTENTION cite file:line evidence for every claim (confidence >80% to act)
• IMPORTANT MUST ATTENTION add a final review todo task to verify work quality
