What Skillforge is

Skillforge is a skill published in the tripleyak/SkillForge repository on GitHub, which has about 900 stars. The repository describes itself as: “A skill creator that proves its skills work. Evidence-driven skill creation for Claude Code and Codex: baseline-tested generation, per-skill regression evals, ecosystem doctor, cross-runtime compile, and an opt-in proactive advisor.”

A skill is a folder with a SKILL.md file: frontmatter with a name and a description, followed by instructions Claude follows. Claude loads a skill automatically when a task matches its description, and you can also run it directly with a slash and its name.

Skills work in Claude Code and in Claude Cowork, which makes Skillforge a portable way to give Claude the same method everywhere.

How to install Skillforge

Claude Code

Download the commands folder from the repository.
Save it as ~/.claude/skills/<skill-name>/SKILL.md for all projects, or .claude/skills/<skill-name>/SKILL.md for one project.
Claude loads it automatically when a task matches; you can also run it with / and its name.

Claude Cowork

Zip the skill folder so SKILL.md sits at the top level of the folder.
Open Customize → Skills, click +, then upload the ZIP.
Start a task that matches the description, or call it by name with /.

New to extending Cowork? Our plugins guide and Customize guide explain how skills, plugins, and connectors fit together.

Arguments

$ARGUMENTS = a SkillForge request, such as:

Instructions

Read ~/.claude/skills/skillforge/SKILL.md.

For all other arguments, use the SkillForge skill workflow with $ARGUMENTS as the input.
Before creating a new skill, confirm SkillForge has checked for existing matching skills.
Report the recommended action clearly: use existing, improve existing, create new, compose skills, or clarify.

Before you install

Read the whole file first. Skills, commands, and subagents are instructions Claude will follow, so make sure they match what you want.
Check which tools, scripts, or MCP servers it uses. Local servers and scripts run with your permissions.
Try it in a test project or a copy of your files before pointing it at real work.
Pin the version you tested, and review changes before updating.
Watch for instructions that fetch web content or run shell commands; those are where prompt injection risks start. See our prompt injection guide.
