Copilot CLI update: chronicle, plugins, and fleet mode

GitHub Checkout

In this episode of GitHub Checkout, we sit down with Copilot CLI Product Manager Ryan Hecht to explore the latest experimental features. 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.

Axolo for Slack

Enable your team to merge pull requests faster

Axolo is a bi-directional Slack & GitHub/GitLab integration.

With Axolo, tech teams collaborate on pull requests seamlessly. Each pull request creates a temporary Slack channel where all information (deployments, pull request checks, and code comments) will be shared. Axolo takes all of the normal back-and-forths on GitHub and Slack to centralize the conversation in ephemeral pull request channels. But this is only step 1!
