update-clankers

This skill should be used when the user asks to "update my clankers", "update my clanker", "update my AI agents", "update my coding agents", "update claude and cursor", or invokes /update-clankers. Detects which AI coding CLI agents are installed on PATH (claude, copilot, cursor-agent, opencode, codex, pi) and runs each one's update command in parallel.
