I have close to 2000 GitHub Copilot CLI sessions on my machine. That history isn’t just sitting there anymore. /chronicle puts it to work 🔥
/chronicle is a set of slash commands that tap into your local session data:
- 📝
/chronicle standup- Summarizes your recent work. Branches, PRs, status. - 💡
/chronicle tips- Personalized recommendations based on your actual usage patterns. - 🔧
/chronicle improve- Suggests updates to copilot-instructions.md based on where Copilot struggled. - 🔄
/chronicle reindex- Rebuilds the session store from history files on disk.
After re-indexing, I ran /chronicle tips and got a few recommendations I hadn’t considered before.
Give it a try! Start with /chronicle reindex. The session store is populated incrementally during sessions, but older sessions from before this feature need to be reindexed first.
One thing: /chronicle is currently experimental. Enable it with /experimental on or the --experimental flag.
