Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.

  • Declares what it does: passed

    SKILL.md parses and declares a name and a description.

    SKILL.md exists, its frontmatter parses, and it declares a name and a description.

  • No undeclared network calls: passed

    Makes no network calls.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

  • No obfuscated payloads: passed

    No encoded or obfuscated payloads.

    No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.

  • No credential access: passed

    Reads no keys, tokens, keychains or credential files.

    Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.

  • No pipe-to-shell installers: passed

    No pipe-to-shell or download-and-run installers.

    No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

  • Pinned to a commit: passed

    Scanned jwynia/agent-skills at e02ec7e226.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

About this skill

What it does

This skill helps diagnose problems within fictional worlds, identifying inconsistencies or weaknesses that make them feel unconvincing. It focuses on issues like a lack of internal logic, societal impact from technology/magic, and shallow cultural depth. The tool then suggests specific interventions to improve the world's believability by ensuring elements have evolved organically rather than being designed superficially. This is not intended for generating worlds from scratch or addressing character-focused plot problems.

When to use it

  • The setting feels like a painted backdrop, lacking independent logic.
  • Technology or magic hasn’t realistically transformed society.
  • Institutions feel artificially created rather than having evolved over time.
  • The economy doesn't make logical sense (e.g., trade without supply chains).
  • Cultures lack depth and feel superficial.

Key capabilities

  • Diagnostic Analysis: Identifies problems across seven world states: Backdrop World, World Without Consequences, Institutions Without History, Economy Doesn’t Make Sense, Belief Systems Are Shallow, Culture Without Depth, and Flat Non-Humans.
  • Intervention Recommendations: Suggests specific interventions like "systemic-worldbuilding," "Consequence Cascade Analysis," "Organic Institutional Design," and more to address identified issues.
  • Consequence Cascade: Analyzes the ripple effects of speculative elements (technology, magic) through 1st, 2nd, and 3rd order consequences – practical effects, systemic adaptations, and cultural evolution respectively.
  • Key Question Prompts: Provides targeted questions to probe technology/magic, institutions, economics, and belief systems within a fictional world.

Example prompts

  • "My fantasy world has powerful mages, but society hasn't changed much. Diagnose the problem."
  • "The economy in my science fiction setting doesn’t make sense. What’s missing?"
  • "This religious order feels very superficial. How can I add more depth to its beliefs?"

Tips & gotchas

  • Not for Creation: This skill is designed to diagnose existing worlds, not generate them from scratch. Use the "systemic-worldbuilding" skill for that purpose.
  • Focus on Systems: The tool excels at identifying issues with systems (economic, social, religious) rather than individual characters or plot points.
  • Evolved vs. Designed: Remember the core principle: good worldbuilding creates the perception of organic evolution and internal logic.
