copilot-cli-things

A curated collection of extensions, skills, and plugins for GitHub Copilot CLI.

Extensions

⚠️ Experimental — Extensions are an experimental feature in Copilot CLI. You must enable them before use:

copilot --experimental
# or type /experimental inside a running session (persists across launches)

Extensions are Node.js processes that add custom tools, hooks, and event-driven behaviors to Copilot CLI via the @github/copilot-sdk.

Extension	Description
cron-task	Schedule recurring tasks — shell commands or agent prompts on a timer
phase-router	LLM-driven intent detection + intelligent model switching
fleet-worktree	Git worktree management for fleet mode — isolated branches per parallel task

Install an Extension

Copy the extension directory to either location:

# Project-level
cp -r extensions/<name> your-project/.github/extensions/

# User-level (all projects)
cp -r extensions/<name> ~/.copilot/extensions/

Restart Copilot CLI or run /extensions to verify loaded extensions.

Skills

All skills are distributed as plugins via this marketplace.
