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.

This is a static scan, not a review. It reads the skill's files; it does not run them, and it cannot tell you whether the skill is any good or whether the code does what its description says. A skill runs with whatever access you give your agent.

About this skill

What it does

This skill helps writers and game designers build richly detailed speculative worlds by systematically exploring how initial changes ripple through society across multiple domains and timescales. It focuses on tracing the consequences of those changes, rather than just introducing new elements. The core principle is to consider not just what a change is, but what it leads to – for example, predicting traffic jams instead of simply inventing automobiles.

When to use it

  • Developing settings for science fiction or fantasy stories where you want realistic and believable world-building.
  • Designing game worlds with complex social, political, and economic systems that evolve realistically over time.
  • Exploring the long-term impact of speculative technologies (like faster-than-light travel) on society.
  • Creating scenarios based on historical divergence points (e.g., a different outcome to a major war).

Key capabilities

  • Consequence Framework: Systematically explores changes across five levels: Initial Divergence, Direct Consequences, Systemic Adaptations, Cultural Evolution, and Intersection Analysis.
  • Domain Exploration: Considers impacts on economic structures, power dynamics, social behaviors, infrastructure, exploitation patterns, language, ethics, belief systems, art, and education.
  • Intersection Analysis: Examines how changes affect different groups (socioeconomic classes, geographic regions, generations, marginalized communities, nations) differently.
  • Depth vs Breadth Decisions: Allows for either a deep exploration of a single consequence chain or a broader overview of multiple impacts.

Example prompts

  • "Let's build a world where immortality drugs are invented. Walk me through the consequences at Level 2: Direct Consequences."
  • “Imagine if the Roman Empire never fell. What would be the systemic adaptations (Level 3) after 1000 years?”
  • "I want to explore how alien contact impacts socioeconomic classes in my world. Show me the intersection analysis for this divergence point.”

Tips & gotchas

  • The skill works best when you have a clear "Initial Divergence Point" – the specific change from our world that defines your speculative setting.
  • Consider focusing on either depth (exploring one consequence chain in detail) or breadth (overviewing multiple impacts), as both approaches are supported.
