GitHub Copilot CLI
A command-line AI programming assistant introduced by GitHub that integrates Copilot capabilities into terminal workflows.
Core Facts
Timeline (last 90 days)
An AI coding CLI is an AI programming assistant that runs in a command-line interface, such as Claude Code, GitHub Copilot CLI, Cursor CLI, etc.
The relevant GitHub Copilot CLI documentation page does not state the specific value for the MCP server startup wait.
The original author explicitly states that they did not actually run these benchmark commands, and the numbers in the article come from timeout limits in the official documentation rather than measured results.
Every programming Agent CLI sends a prefix before the task begins, including the system prompt, built-in tool definitions, configured MCP server tools, and instruction files found along the way.
Copilot CLI loads `AGENTS.md`, `.github/copilot-instructions.md`, `~/.copilot/copilot-instructions.md`, `CLAUDE.md`, and `GEMINI.md` all merged together at startup.
Copilot CLI's programmatic reference documentation does not document a usage field, and its `-s` flag suppresses statistics; after starting `copilot`, entering `/context` shows the layer-by-layer breakdown of System Prompt, Custom Instructions, System Tools, MCP Tools, and Messages separately.
Backer Concierge is an agent built by a developer using GitHub Copilot CLI together with Microsoft Foundry and Azure skills, and it can remember conversation context and refuses to fabricate information.
GitHub Copilot CLI reads and merges AGENTS.md, CLAUDE.md and GEMINI.md in the repository, and the documentation does not define the precedence among them.
GitHub Copilot CLI's user-level configuration is all located in ~/.copilot, where settings.json is the main configuration and config.json is internal state.
TERMy cannot understand complex tasks described in natural language the way Warp AI or GitHub Copilot CLI can.
