GitHub Copilot CLI

Name: Watchfire
Author: Watchfire

GitHub Copilot from the command line, running in yolo mode behind the sandbox.

What is GitHub Copilot CLI?

GitHub Copilot CLI is GitHub's command-line Copilot agent. It signs in via `gh` or its own flow and stores config, MCP setup, and session history under `~/.copilot/`.

GitHub Copilot CLI + Watchfire

Watchfire gives each Copilot session its own `COPILOT_HOME`, symlinks your real `~/.copilot/{config.json,mcp-config.json,session-store.db}` into it, and points Copilot at a Watchfire-generated `AGENTS.md` via `COPILOT_CUSTOM_INSTRUCTIONS_DIRS`. Sessions run in yolo mode (`--allow-all`) — the Watchfire sandbox is the boundary, not Copilot's prompt gate.

Uses `COPILOT_CUSTOM_INSTRUCTIONS_DIRS` to load the per-session `AGENTS.md`
