Worktrunk

Worktrunk

Help users work with Worktrunk, a CLI tool for managing git worktrees.

Available Documentation

Reference files are synced from worktrunk.dev documentation:

• reference/config.md: User and project configuration (LLM, hooks, command defaults)
• reference/hook.md: Hook types, timing, and execution order
• reference/switch.md, merge.md, list.md, etc.: Command documentation
• reference/llm-commits.md: LLM commit message generation
• reference/tips-patterns.md: Language-specific tips and patterns
• reference/shell-integration.md: Shell integration debugging
• reference/troubleshooting.md: Troubleshooting for LLM and hooks (Claude-specific)

For command-specific options, run wt --help. For configuration, follow the workflows below.

Two Types of Configuration

Worktrunk uses two separate config files with different scopes and behaviors:

User Config (~/.config/worktrunk/config.toml)

• Scope: Personal preferences for the individual developer
• Location: ~/.config/worktrunk/config.toml (never checked into git)
• Contains: LLM integration, worktree path templates, command settings, user hooks, approved commands
• Permission model: Always propose changes and get consent before editing
• See: reference/config.md for detailed guidance

Project Config (.config/wt.toml)

• Scope: Team-wide automation shared by all developers
• Location: /.config/wt.toml (checked into git)
• Contains: Hooks for worktree lifecycle (pre-start, pre-merge, etc.)
• Permission model: Proactive (create directly, changes are reversible via git)
• See: reference/hook.md for detailed guidance

Determining Which Config to Use

When a user asks for configuration help, determine which type based on:

User config indicators:

• "set up LLM" or "configure commit generation"
• "change where worktrees are created"
• "customize commit message templates"
• Affects only their environment

Project config indicators:

• "set up hooks for this project"
• "automate npm install"
• "run tests before merge"
• Affects the entire team

Both configs may be needed: For example, setting up commit message generation requires user config, but automating quality checks requires project config.

Core Workflows

Setting Up Commit Message Generation (User Config)

Most common request. See reference/llm-commits.md for supported tools and exact command syntax.

1. Detect available tools

``bash which claude codex llm aichat 2>/dev/null ``

1. If none installed, recommend Claude Code (already available in Claude Code sessions)

1. Propose config change — Get the exact command from reference/llm-commits.md

``toml [commit.generation] command = "..." # see reference/llm-commits.md for tool-specific commands `` Ask: "Should I add this to your config?"

1. After approval, apply

• Check if config exists: wt config show
• If not, guide through wt config create
• Read, modify, write preserving structure

1. Suggest testing

``bash wt step commit --show-prompt | head # verify prompt builds wt merge # in a repo with uncommitted changes ``

Setting Up Project Hooks (Project Config)

Common request for workflow automation. Follow discovery process:

1. Detect project type

``bash ls package.json Cargo.toml pyproject.toml ``

1. Identify available commands

• For npm: Read package.json scripts
• For Rust: Common cargo commands
• For Python: Check pyproject.toml

1. Design appropriate hooks (7 hook types available)

• Dependencies (fast, must complete) → pre-start
• Tests/linting (must pass) → pre-commit or pre-merge
• Long builds, dev servers → post-start
• Terminal/IDE updates → post-switch
• Deployment → post-merge
• Cleanup tasks → pre-remove

1. Validate commands work

``bash npm run lint # verify exists which cargo # verify tool exists ``

1. Create .config/wt.toml

```toml # Install dependencies when creating worktrees pre-start = "npm install"

# Validate code quality before committing [pre-commit] lint = "npm run lint" typecheck = "npm run typecheck"

# Run tests before merging pre-merge = "npm test" ```

1. Add comments explaining choices

1. Suggest testing

``bash wt switch --create test-hooks ``

See reference/hook.md for complete details.

Adding Hooks to Existing Config

When users want to add automation to an existing project:

1. Read existing config: cat .config/wt.toml

1. Determine hook type - When should this run?

• Creating worktree (blocking) → pre-start
• Creating worktree (background) → post-start
• Every switch → post-switch
• Before committing → pre-commit
• Before merging → pre-merge
• After merging → post-merge
• Before removal → pre-remove

1. Handle format conversion if needed

Single command to named table: ```toml # Before pre-start = "npm install"

# After (adding db:migrate) [pre-start] install = "npm install" migrate = "npm run db:migrate" ```

1. Preserve existing structure and comments

Validation Before Adding Commands

Before adding hooks, validate:

# Verify command exists
which npm
which cargo

# For npm, verify script exists
npm run lint --dry-run

# For shell commands, check syntax
bash -n -c "if [ true ]; then echo ok; fi"

Dangerous patterns — Warn users before creating hooks with:

• Destructive commands: rm -rf, DROP TABLE
• External dependencies: curl http://...
• Privilege escalation: sudo

Permission Models

User Config: Conservative

• Never edit without consent - Always show proposed change and wait for approval
• Never install tools - Provide commands for users to run themselves
• Preserve structure - Keep existing comments and organization
• Validate first - Ensure TOML is valid before writing

Project Config: Proactive

• Create directly - Changes are versioned, easily reversible
• Validate commands - Check commands exist before adding
• Explain choices - Add comments documenting why hooks exist
• Warn on danger - Flag destructive operations before adding

Find specific sections with grep:

grep -A 30 "### pre-start" reference/hook.md
grep -A 20 "## Warning Messages" reference/shell-integration.md

Advanced: Agent Handoffs

When the user requests spawning a worktree with an agent in a background session ("spawn a worktree for...", "hand off to another agent"), use the appropriate pattern for their terminal multiplexer. Substitute ` with the CLI you are running as: claude for Claude Code, 'opencode run'` for OpenCode.

tmux (check $TMUX env var):

tmux new-session -d -s  "wt switch --create  -x  -- ''"

Zellij (check $ZELLIJ env var):

zellij run -- wt switch --create  -x  -- ''

Requirements (all must be true):

• User explicitly requests spawning/handoff
• User is in a supported multiplexer (tmux or Zellij)
• The user's project instructions (CLAUDE.md or AGENTS.md) or an explicit prompt authorize this pattern

Do not use this pattern for normal worktree operations.

Example (tmux, Claude Code):

tmux new-session -d -s fix-auth-bug "wt switch --create fix-auth-bug -x claude -- \
  'The login session expires after 5 minutes. Find the session timeout config and extend it to 24 hours.'"

Example (Zellij, OpenCode):

zellij run -- wt switch --create fix-auth-bug -x 'opencode run' -- \
  'The login session expires after 5 minutes. Find the session timeout config and extend it to 24 hours.'
