Agent Plugins

Ponytail gives Codex, Claude Code, OpenCode, and other coding agents a minimal-implementation ruleset, six companion Skills, and lifecycle hooks. It prioritizes existing code, standard libraries, and native platform features without removing security, validation, error handling, or accessibility safeguards.

A Microsoft HVE-maintained GitHub Copilot workflow pack that combines agents, prompts, instructions, and skills for research, planning, implementation, review, and security checks.
