Worker Skill

Spawn a Claude worker in an isolated git worktree.

Usage

/worker <branch-name> <task description>

Examples

/worker feat/add-logging Add structured logging to the supervisor module
/worker fix/auth-bug Fix the authentication bypass in the API
/worker refactor/cleanup Refactor the instance manager for clarity

Instructions

When the user invokes /worker, follow these steps:

1. Parse Arguments

Extract the branch name (first argument) and task description (remaining text).

2. Create Worktree

# Get project name for worktree prefix
PROJECT=$(basename $(git rev-parse --show-toplevel))
WORKTREE_PATH="../${PROJECT}-$(echo $BRANCH | tr '/' '-')"

# Create the worktree with a new branch
git worktree add "$WORKTREE_PATH" -b "$BRANCH"

3. Spawn Worker Claude

Run a Claude instance in the worktree with full autonomy:

cd "$WORKTREE_PATH" && claude --print --dangerously-skip-permissions "$TASK_DESCRIPTION"

4. Push and Create PR

After the worker completes successfully and has made commits:

# Push the branch to origin
git push -u origin "$BRANCH"

# Create PR with auto-generated summary
gh pr create --title "<commit message or task summary>" --body "$(cat <<'EOF'
## Summary
<brief description of changes>

## Changes
<list of key changes made>

---
🤖 Generated by Claude worker
EOF
)"

# Enable auto-merge (will merge automatically when CI passes)
gh pr merge --auto --squash

5. Report Results

After the worker completes:

1. Show the worker's output
2. Show any commits made: git log $BRANCH --oneline -5
3. Show the PR URL if created
4. Offer next steps:
   • Review the PR
   • Continue working (spawn another worker command)
   • Clean up the worktree

Important Notes

• Workers have full autonomy (--dangerously-skip-permissions)
• Each worker gets its own branch - no conflicts with main work
• Workers push their branch and create PRs when done
• Use git worktree list to see active workers
• Use git worktree remove <path> to clean up

Tip: Run karkinos watch in another terminal to monitor worker progress in real-time, or use karkinos watch --spawn to open it automatically.
