What problem does it solve? Teams running multi-model research and review workflows need additional AI perspectives without extra API costs. This Skill adds GitHub Copilot CLI as an optional provider in the Claude Octopus ecosystem, using the existing Copilot subscription instead of a separate paid API. ## Core Features & Use Cases - Programmatic dispatch: Invokes Copilot through the official copilot -p non-interactive mode with --no-ask-user, avoiding reverse-engineered endpoints. - Flexible authentication: Supports COPILOT_GITHUB_TOKEN fine-grained PATs, GH_TOKEN/GITHUB_TOKEN, keychain OAuth via copilot login, and fallback to existing gh CLI auth. - Graceful degradation: Silently skips Copilot when the CLI is missing or unauthenticated, reassigning its role to other providers without errors. - Use Case: During a multi-provider research task on WebSocket authentication patterns, Copilot contributes a research perspective alongside Codex and Antigravity, with each prompt counting as one premium request against the existing subscription quota. ## Quick Start Ask the assistant to add GitHub Copilot as a provider for the next multi-model research task and run the doctor check to confirm authentication.
