GitHub Copilot app adds slash commands for faster workflows

The GitHub Copilot app's slash command system reflects a shift in how AI coding assistants integrate into developer workflows. The article makes clear that the app's commands differ fundamentally from the CLI version because the environments are different: the CLI commands manage terminal-level tasks (directories, working directory, terminal access), while the app provides a visual interface that handles project context automatically. This design choice suggests GitHub is optimizing slash commands for the strengths of each interface—terminal-first for the CLI, workflow-first for the desktop app.

The command set reveals a deliberate progression through common development activities. Developers begin with /plan to break down a task, then use /spar to stress-test the approach before committing, then move to /autopilot to automate implementation. The /rubber-duck command is positioned as a quality gate—a way to catch blind spots before pushing code. Finally, /orchestrate handles the multi-repository coordination that larger features often require. This sequence suggests the commands are meant to support a complete feature lifecycle, not just isolated tasks.

The mention that /clear and /model commands work in both CLI and app versions indicates GitHub is building a consistent Copilot vocabulary across platforms where it makes sense, while allowing context-specific commands to flourish where they add the most value.
