What Skill Porting does

Skill Porting installs skills from Claude Code plugin marketplaces, Codex plugins, skills.sh registry names, GitHub repos, or local folders into Penguin's agent_state/skills directory after reviewing all files and normalizing SKILL.md frontmatter. Use it to add a third-party skill safely.

Skill Porting is cataloged under AI Engineering on DirSkills. Skill Porting comes from a repository tagged agent, agentic-ai, ai, build-tool and claude-code.

Documentation

README

Excerpt

Skill Porting

Penguin has no plugin mechanism and needs none: the wider ecosystem's plugins are wrappers around plain skill directories — a SKILL.md plus support files — which is exactly the shape Penguin installs. This skill turns any common external source into installed skills: locate the source, fetch it at a pinned revision, review everything, normalize the frontmatter, copy into agent_state/skills/<name>/, verify.

Before you start

If the user's message only invokes this skill (e.g. "use skill-porting skill") without naming a skill or a source, ask what skill they want and where it comes from (a marketplace plugin name, a repo URL, a skills add spec, or a local path).

This is the opening of the README. Read the full README on GitHub.
