We cover the plugin marketplace, the /chronicle slash command for self-healing prompts, and how to run Claude Opus 4.6, GPT-5.4, and Gemini 3 simultaneously. We also walk through how /fleet mode and autopilot can handle massive refactoring tasks while you step away.

Repo maintenance is hard — you could use a hand

Ranger is a sidekick for repo maintainers. It reduces the burden of repository maintenance by automating common tasks, like:

  • Auto-merging pull requests when all the status checks pass
  • Auto-closing issues when a specific label is applied after a preconfigured amount of time
  • Creating frequent comments in a standardized manner
  • Auto-deleting branches after pull requests have been merged
  • and more!
