Choose how to use this skill
You do not need every option. Choose the path your AI client supports. The stable page stays the same; versioned files are immutable.
1. Native installer
This listing has no registered native installer command. Use the complete package or source fallback below, depending on what your client supports.
Do not guess an installer command or replace an existing version without reviewing the diff.
2. Complete package recommended
Download the ZIP when available. It includes SKILL.md plus the references, security notes and version metadata.
No complete ProSkills package is published for this listing yet.3. Prompt-only
Copy the prompt above when the agent can read the stable page or when you want to adopt the workflow without installing a skill.
Need only the instruction file?
Download SKILL.md only if your client requires a single file. The complete ZIP is safer for a full installation because it preserves the references and release context.
No path installs or executes anything by itself. Your agent still needs access to the project files. Before updating, compare the installed version and review the diff.

OSS AI Skills Collection
A comprehensive collection of AI assistant skills (SKILL.md files) following the skillreg.dev specification, designed to help to use and extend open-source projects (for plugins). Note: we test the majority of them and improving based on asking to the agents to extend the skills based on their experience.
What is this?
This repository provides reusable skill definitions that can be loaded into AI coding assistants. Each skill encapsulates domain knowledge, best practices, and workflows for specific tasks in open-source development.
