    Sample input

    I want to create a new professional skill called "Legacy Refactoring with Grok" that helps developers safely modernize old codebases.

    Please follow the Agensi Skill Authoring with Grok framework. Start with Phase 1 and help me define the exact problem, the primary deliverable, and the "When You DON’T Need This Skill" boundaries before we write any procedure.

    Sample output

    (Full structured SKILL.md following the 5-phase process, with complete Expected Output template and realistic completed example — exactly what the skill is designed to produce.)

    About This Skill

    Build Market-Leading AI Skills

    Stop writing vague prompts and start building professional-grade agent tools. This skill provides a complete, developer-centric methodology for designing and structuring SKILL.md files specifically optimized for Grok and the Agensi marketplace.

    What it does

    It guides you through a multi-phase engineering process to transform loose ideas into precise operating procedures. It forces the definition of hard boundaries, stop conditions, and "Expected Output Contracts" that ensure your skills are reliable, high-fidelity, and valuable to buyers.

    Why use this skill

    Standard prompting often fails when agents treat instructions as optional suggestions. This framework uses imperative language and structured phases to ensure Grok follows procedures with exactness. It covers the entire lifecycle from pain point definition to marketplace optimization, including anti-pattern detection and quality gates.

    What you get

    • A proven 5-phase engineering process for authoring SKILL.md files
    • Strong imperative language + explicit stop conditions that dramatically improve agent fidelity
    • Mandatory "Expected Output Contracts" that force consistent, structured results
    • Anti-pattern detection and quality gates used by top-performing skills
    • Marketplace-optimized structure (pain hook, value proposition, Common Pitfalls, Works Well With)

    The result is skills that agents actually follow and buyers actually purchase.

    Use Cases

    • Write high-fidelity SKILL.md files that Grok follows with precision
    • Increase marketplace conversion with professional value-driven documentation
    • Transform loose prompts into rigorous agent operating procedures
    • Standardize skill development across a team or personal library

    This meta skill is intended for creators who are building skills for themselves or for publication. It requires the ability to read reference skills and write new ones. It does not execute the skills it helps create.

    This skill follows the open SKILL.md standard and is specifically optimized for **Grok** inside the **Grok Build CLI / TUI**. The techniques also work with other agents that support structured procedural instructions.
