This skill should be used when the user says "ship it", "arness code ship", "create PR", "open pull request", "push and PR", "commit and push", "wrap up", "ship the feature", "ship the fix", "ready to ship", "push changes", "finalize", "finish up", or wants to commit, push, and optionally open a pull request. Guides through branching, staging, committing with meaningful messages, pushing, and PR creation. Works standalone or as the final Arness pipeline step. Do NOT use this for reviewing PRs — use /arn-code-review-pr for that.
