1> **Host: Codex CLI** — This skill was designed for Claude Code and adapted for Codex.
2> Cross-reference commands use installed skill names in Codex rather than `/octo:*` slash commands.
3> Use the active Codex shell and subagent tools. Do not claim a provider, model, or host subagent is available until the current session exposes it.
4> For host tool equivalents, see `skills/blocks/codex-host-adapter.md`.

7# GitHub Copilot Provider Skill
8 
9## Overview
10 
11GitHub Copilot CLI (GA since Feb 2026) serves as an optional provider in the Claude Octopus
12multi-LLM ecosystem. Integration uses the official `copilot -p` programmatic mode, not
13reverse-engineered API endpoints.

15**Core principle:** Copilot supplements existing providers for research and exploration at
16zero additional cost (uses existing GitHub Copilot subscription). Each prompt counts as one
17premium request against your subscription quota.

19**Agent types:** `copilot` (general), `copilot-research` (research-focused)

22## Detection
23 
24```bash
25# Check copilot CLI is available
26if ! command -v copilot &>/dev/null; then
27  # Copilot CLI not installed — silently skip
28  return 0
29fi
30```
31 
32**Graceful degradation:** When Copilot CLI is unavailable or unauthenticated, silently skip.
33Other providers continue to operate normally.

36## Authentication
37 
38Copilot CLI checks credentials in this precedence order:
39 
401. `COPILOT_GITHUB_TOKEN` env var (highest priority — fine-grained PAT with "Copilot Requests" permission)
412. `GH_TOKEN` env var
