    skill-builder: Build AI Agent Skills From Plain English

    skill-builder scaffolds and audits production-ready skills for AI coding agents from a plain-English description — no boilerplate, no guesswork.

    skill-builder scaffolds and audits production-ready skills for AI coding agents from a plain-English description. Tell it what domain the skill should cover, and it generates SKILL.md, hook configs, reference files, and a complete marketplace-ready repo — no boilerplate, no guesswork. Built and open-sourced by Shahriar Labs.

    The Problem It Solves

    Writing a good AI agent skill is harder than it looks. The SKILL.md needs to be precise enough that the agent never misunderstands its scope. Hooks need to fire at the right lifecycle events. References need to be structured for fast context retrieval. Without a scaffold, first-time skill authors spend days on boilerplate that should take minutes.

    skill-builder handles all of that. You describe the skill in plain English ("a skill that generates production GDScript for Godot 4.3") and it produces the entire repo structure with correct frontmatter, trigger conditions, and implementation guidance.

    Build Mode vs Audit Mode

    Build mode: generates a new skill from scratch. Input a description, get a complete SKILL.md, hooks/, references/, and README. The output is immediately deployable to the Agent Skills marketplace.

    Audit mode: reviews an existing skill and flags: missing trigger conditions, vague instructions, absent safety rules, incomplete references. Run it on any skill before publishing to catch issues that would cause agents to misfire in production.

    The Agent Skills Ecosystem

    skill-builder targets the Agent Skills open standard — 32+ agent types including softco, latex-engineer, Godot-Skill, and seo-master. Skills built with skill-builder are interoperable across Claude Code, Cursor, and Cline. See the full list in our open-source skills hub.

    Frequently Asked Questions

    What is skill-builder?
    An AI skill that generates complete, production-ready agent skill repos from a plain-English description.
    What is an AI agent skill?
    A packaged, reusable capability that extends what an AI coding agent can do — encapsulating domain knowledge, prompts, and workflows.
    Does it support all agent frameworks?
    Yes — targets the Agent Skills open standard, compatible with Claude Code, Cursor, Cline.
    Can I audit existing skills?
    Yes. Audit mode reviews any skill for completeness and flags issues before publishing.
