Copilot Cli

This lets you call GitHub Copilot CLI from inside Claude Code when you want a second opinion or need a specific model like GPT-5, Gemini, or a different Claude variant. It's built around non-interactive invocations with explicit model selection, least-privilege permission flags, and session export to markdown. Useful when you want side-by-side model comparisons on the same refactor, or when you're scripting repetitive Copilot tasks. The skill emphasizes English prompts, conservative tooling permissions, and treating external model output as suggestions that still need validation. It's a delegation layer, not a replacement for your own judgment.

Copilot CLI Delegation

Delegate selected tasks from Claude Code to GitHub Copilot CLI using non-interactive commands, explicit model selection, safe permission flags, and shareable outputs.

Overview

This skill standardizes delegation to GitHub Copilot CLI (copilot) for cases where a different model may be more suitable for a task. It covers:

Non-interactive execution with -p / --prompt
Model selection with --model
Permission control (--allow-tool, --allow-all-tools, --allow-all-paths, --allow-all-urls, --yolo)
Output capture with --silent
Session export with --share
Session resume with --resume

Use this skill only when delegation to Copilot is explicitly requested or clearly beneficial.

When to Use

Use this skill when:

The user asks to delegate work to GitHub Copilot CLI
The user wants a specific model (for example GPT-5.x, Claude Sonnet/Opus/Haiku, Gemini)
The user asks for side-by-side model comparison on the same task
The user wants a reusable scripted Copilot invocation
The user wants Copilot session output exported to markdown for review
