Each prompt counts as one premium request against your subscription quota. **Agent types:** `copilot` (general), `copilot-research` (research-focused) --- ## Detection ```bash # Check copilot CLI is available if ! command -v copilot &>/dev/null; then # Copilot CLI not installed — silently skip return 0 fi ``` **Graceful degradation:** When Copilot CLI is unavailable or unauthenticated, silently skip. Other providers continue to operate normally. --- ## Authentication Copilot CLI checks credentials in this precedence order: 1. `COPILOT_GITHUB_TOKEN` env var (highest priority — fine-grained PAT with "Copilot Requests" permission) 2. `GH_TOKEN` env var 3. `GITHUB_TOKEN` env var 4. OAuth token from system keychain (via `copilot login`) 5.
