How to Check Token Usage in GitHub Copilot CLI【/context】
Overview
When your conversation’s been going for a while, ever wondered “how much context am I actually using right now?”
If you hit the limit, older information starts getting dropped — and you want to act before that happens. The /context command shows you exactly where you stand.
Usage
Run this in Copilot CLI:
/copilot> /contextYou’ll see a breakdown of your context window token usage.
What You’ll See
- Current token usage
- Percentage of context window used
- Breakdown by category (conversation history, file references, etc.)
When the numbers start looking high, it’s a good signal to run /compact.
Combo with /compact
- Run
/contextto check usage - If it’s high, run
/compactto compress - Run
/contextagain to confirm
A simple workflow for keeping your context lean and your responses sharp.
