This skill should be used when the user says "pick issue", "work on issue", "arness code pick", "arness code pick issue", "arn-code-pick-issue", "grab issue", "pick from backlog", "what should I work on", "show issues", "find issue", "browse issues", "next issue", "select issue", "choose issue", "what's unblocked", "work on next feature", "pick from feature tracker", or wants to browse issues filtered by Arness labels, select one, and route it to the appropriate Arness pipeline skill for implementation. Supports local-first dependency resolution from a greenfield feature backlog when available. Requires an issue tracker (GitHub or Jira) to be configured for remote issue browsing. Do NOT use this for creating new issues — use /arn-code-create-issue for that.
