Allow reasoning effort to be set through the CLI #1048
Description
Describe the feature or problem you'd like to solve
For example, when I call copilot --model gpt-5.2 I also want to be able to pass --reasoning-effort high
Proposed solution
when calling copilot via the CLI, the reasoning effort can be set instead of only in the interactive mode.
just expose an option called --reasoning-effort or -r (if that isn't taken already).
Example prompts or workflows
for ((i=1;i<=n;i++)); do echo "=== run $i/$n ==="; copilot --model "gpt-5.2" --reasoning "high" -s -p "$p" --yolo; done
