Init Skill

Initializes an isolated git worktree for feature development, enabling parallel work without affecting the main branch.

When to Use

• User says "initialize a worktree for X"
• User says "use compounder to init"
• User wants to start a new feature branch
• User needs isolated development environment

Quick Start

# Via skill (if permissions are configured)
/compounder:init "my-feature"

# Direct script call (always works)
scripts/init-worktree.sh "my-feature"

What Gets Created

Item	Location	Description
Worktree	../compounder-{feature}	Sibling directory to main repo
Branch	feat/{feature}	Based on current HEAD

Invocation Methods

Method 1: Skill Tool (May Require Permission)

Skill: compounder:init
Args: "feature-name"

Note: This may fail with permission error if bash command isn't pre-approved.

Method 2: Direct Script Call (Recommended)

/path/to/scripts/init-worktree.sh "feature-name"

The script is located at:

$CLAUDE_PLUGIN_ROOT/scripts/init-worktree.sh

Or in cached plugins:

~/.claude/plugins/cache/jero2rome-compounder/compounder/*/scripts/init-worktree.sh

Debugging Journey (Reference for Claude)

This section documents the trial-and-error process that led to successful invocation:

Attempt 1: Skill Tool

Tool: Skill
skill: "compounder:init"

Result: FAILED

Error: Bash command permission check failed for pattern...
This command requires approval

Lesson: The Skill tool internally runs a bash script that wasn't in the allowed permissions list.

Attempt 2: Ask User for Feature Name

Tool: AskUserQuestion
questions: [{"question": "What feature?", "options": [{"label": "Enter custom"}]}]

Result: FAILED

Error: Array must contain at least 2 element(s)

Lesson: AskUserQuestion requires at least 2 options. Can't use it for single free-text input.

Attempt 3: Direct Script Without Argument

Tool: Bash
command: /path/to/scripts/init-worktree.sh

Result: FAILED

Error: Feature name required
Usage: /compounder:init "my-feature"

Lesson: The script requires a positional argument for the feature name.

Attempt 4: Direct Script With Argument (SUCCESS)

Tool: Bash
command: /path/to/scripts/init-worktree.sh "test-comp"

Result: SUCCESS

Creating worktree and branch...
HEAD is now at ad08615 ...
Worktree created: ../compounder-test-comp
Branch created: feat/test-comp

Key Learnings

1. Skill tool limitation: Underlying bash commands need explicit permission approval
2. Workaround: Call the script directly via Bash tool with full path
3. Script location: $CLAUDE_PLUGIN_ROOT/scripts/init-worktree.sh or cached path
4. Required argument: Feature name MUST be passed as positional argument
5. AskUserQuestion: Requires 2+ options; can't use for single text input

Required Permission

To auto-approve the init script, add to .claude/settings.json:

{
  "permissions": {
    "allow": [
      "Bash(*/scripts/init-worktree.sh:*)"
    ]
  }
}

After Initialization

1. Switch to worktree:

   cd ../compounder-{feature} && claude
   

2. Start workflow:

   • "Let's ideate [feature]" -> feature description
   • "Create a spec" -> spec.md
   • "Create a plan" -> plan.md
   • "Create tasks" -> tasks.md
   • "Execute the tasks" -> implementation

3. Cleanup after merge:

   git worktree remove ../compounder-{feature}
   

Handoff

After init completes, guide user to:

1. Open new terminal in worktree directory
2. Start Claude Code in that directory
3. Begin with ideate skill for the feature
