Get more out of your GitHub Copilot session history with

GitHub Copilot CLI has an experimental `/chronicle` command that turns your local session history into actionable insights. It offers four subcommands: `standup` generates a daily summary of completed and in-progress work tied to branches and PRs; `tips` analyzes your session patterns to give personalized usage recommendations; `improve` detects friction points and suggests concrete additions to your `.github/copilot-instructions.md`; and `reindex` rebuilds the session store index. Beyond subcommands, you can ask free-form questions about your own CLI usage patterns, such as what time of day you're most effective or whether you've worked on authentication recently. Enable it with `/experimental on` or the `--experimental` flag.
