Update GitHub Copilot CLI from 0.0.385 to 0.0.387 #10776

Copilot · 2026-01-20T02:32:57Z

Updates the default GitHub Copilot CLI version to 0.0.387, incorporating skill tool optimizations for large directories, a new ask_user tool for interactive clarification, and plan mode improvements.

Changes

Constants: Bumped DefaultCopilotVersion from "0.0.385" to "0.0.387" in pkg/constants/constants.go
Tests: Updated version expectation in constants_test.go
Workflows: Recompiled 86 workflow lock files to reference new CLI version

Version Changes

// Before
const DefaultCopilotVersion Version = "0.0.385"

// After
const DefaultCopilotVersion Version = "0.0.387"

All workflow lock files now install and reference Copilot CLI 0.0.387:

sudo VERSION=0.0.387 bash /tmp/copilot-install.sh

Integration Testing

Per the warning in constants.go, full integration tests should be run to ensure compatibility with the new Copilot CLI version.
