    AI Agent Skill Foundry — Build Production-Ready Skills

    Example session with this skill installed

    I have an idea for a 'Code Reviewer' skill. I want to architect it to focus on security vulnerabilities in Python web apps. Can you run the ARCHITECT and BUILD modes for this?

    • Read your context and instructions
    • Compiled the ai agent foundry

    The 'Code Reviewer' skill has been architected and built. The focus is restricted to identifying OWASP Top 10 vulnerabilities in Python-based web frameworks.

    AI Agent Skill: Python Security Sentinel

    
    # Skill: Python Security Sentinel
    # Version: 1.0.0
    
    ## Primary Job
    Perform automated security audits on Python web application code to identify SQL injection, XSS, and broken authentication.
    
    ## Expert Mechanism
    1. **Taint Analysis**: Trace user input from request objects to database sinks.
    2. **Pattern Matching**: Scan for unsafe functions (e.g., `os.system`, `eval`).
    3. **Context Evaluation**: Assess if middleware or decorators (e.g., `@login_required`) are correctly applied.
    
    ## Operating Workflow
    INTAKE (Code Snippet) -> CLASSIFY (Framework: Django/Flask) -> SCAN (Vulnerability Patterns) -> VERIFY (Context Check) -> REPORT (Remediation Steps)
    
    ## Security Model
    - Treats all input code as untrusted data.
    - Never executes the provided code.
    - Discloses if a library version is too old for a known CVE check.
    
    ## Reliability & Verification
    - **Test Case**: Input code with intentional SQLi via string formatting. 
    - **Expected**: Fail gate if `cursor.execute(f"...")` is found without param binding.
    

    Next steps

    1. Run BENCHMARK mode to generate a suite of vulnerable and safe code samples.
    2. Execute SECURITY mode to test the sentinel against prompt injection attempts.
    3. Move to PRODUCTIZE to generate the final Agensi marketplace description.

    About this skill

    AI Agent Skill Foundry is an expert workflow for turning rough AI agent skill ideas into structured, tested, security-reviewed, marketplace-ready products.

    Instead of generating a simple prompt, it guides the complete skill-development lifecycle:

    IDEA → DISCOVER → FOCUS → ARCHITECT → BUILD → TEST → SECURE → VERIFY → PRODUCTIZE → CERTIFY → RELEASE → EVOLVE

    Use it to design new AI agent skills, audit existing skills, identify weak workflows, create evaluation tests, analyze failure modes, strengthen security boundaries, verify evidence, improve marketplace positioning, and prepare skills for release.

    What it does Discover valuable AI agent skill opportunities Turn vague ideas into a focused professional job Design reusable expert workflows Define inputs, outputs, states, decision rules, and quality gates Build production-ready SKILL.md architectures Create benchmarks and evaluation criteria Analyze failure modes and edge cases Perform security and instruction-integrity reviews Apply least-privilege and data-minimization principles Verify evidence and prevent unsupported claims Assess economic value and repeatability Productize skills for marketplace buyers Create release gates and certification criteria Track changes and regression risks Improve existing skills using evidence rather than guesswork Designed for AI agent skill creators AI automation builders Prompt engineers AI consultants AI product builders Claude / Codex / Cursor / Copilot users SKILL.md developers Agent workflow designers AI marketplace sellers Technical creators building reusable AI workflows Use it when you want to Build a new AI agent skill from an idea Turn a prompt into a reusable expert workflow Audit an existing SKILL.md Improve a weak or generic skill Create skill evaluation tests Find failure modes before release Review a skill for security risks Strengthen reliability and consistency Prepare a skill for marketplace submission Improve an existing skill without breaking previous behavior Decide whether a skill is ready for release Core differentiator

    Most prompt workflows focus on producing an answer.

    AI Agent Skill Foundry focuses on engineering the system that repeatedly produces better answers.

    It separates

    Intent → Workflow → Mechanism → Testing → Evidence → Security → Product → Release → Evolution

    The result is designed to be reusable, testable, explainable, and maintainable rather than being a one-off prompt.

    Quality controls

    The methodology includes explicit gates for

    scope capability selection evidence sufficiency failure analysis security privacy authorization tool necessity regression economic viability marketplace readiness release state

    It does not promise guaranteed sales, marketplace approval, rankings, or revenue. Instead, it provides a structured engineering and productization process for improving the underlying skill.

    Does not perform external API writes, live deployment, or account actions. Requires user-provided intent or domain concepts to initiate the lifecycle.

    How to use

    1. 1

      Connect your agent to the Agensi MCP

      Copy the prompt and paste it into Claude, ChatGPT, Cursor or any agent that supports MCP. It sets up the connection for you. Manual setup

    2. 2

      Sign in to Agensi

      Your agent shows a sign-in link. Sign in and click Allow.

    3. 3

      Ask for what you need

      Your agent loads this skill and uses it on your task. It always asks before buying a skill.

    Frequently Asked Questions

    This tool is a comprehensive development framework that guides you through the full lifecycle of creating production-ready skills, moving beyond simple prompts to professional-grade architectures with built-in testing, security, and marketplace optimization.

    The Foundry is platform-agnostic and designed to work with any LLM or IDE that supports structured agent development, including Claude, ChatGPT, Cursor, and frameworks using the SKILL.md format.

    The purchase includes the complete expert workflow documentation, a series of structured development gates, evaluation criteria for testing, and the security review protocols required to prepare a skill for release.

    Yes, it is specifically designed to audit and refine existing skills by identifying weak workflows, strengthening security boundaries, and implementing regression tests to ensure updates don't break previous behavior.

    The workflow includes explicit security and privacy gates that enforce least-privilege principles, data minimization, and instruction-integrity reviews to prevent prompt injection and unauthorized actions.

    No technical setup or software installation is required; you can begin using the workflow immediately within your preferred AI interface to start architecting your skills.
