Curated by Skill Harbor — a world-architect skill for fiction writers and game designers: magic and technology system design (Sanderson's Laws), cultural and societal architecture that avoids monocultures, historical timelines built on cause and effect, geography and climate logic, religions people would actually believe, economies, naming languages, and world bibles. Its philosophy is the "one big lie" principle — ask the audience to accept one departure from reality, then be ruthlessly consistent about every implication — and the iceberg rule: show 10%, hint at 90%. Grounded in companion reference files for creation patterns, failure diagnosis ("sharp edges"), and validation rules. Discovered via skills.sh, listed here with credit to its creator by @omer-metin. Honest caveats: persona-driven with a strong opinionated voice ("world architect" who has made every mistake); depends on the companion reference files (patterns.md, sharp_edges.md, validations.md) that must ship with the skill; fiction and games only — not for technical documentation. Skill Harbor never reviews the code, review it yourself before use. Not verified.
Version:
Install
Prerequisites: none — no account, no API keys. You need a fictional world, game setting or story to build. Install "Worldbuilding" for me. A world-architect skill for fiction and games: magic systems, cultures, timelines, geography, religions, economies and lore consistency — built on the "one big lie" principle and Sanderson's Laws. Repository: https://github.com/omer-metin/skills-for-antigravity/blob/main/skills/worldbuilding/SKILL.md 1. Fetch the SKILL.md file for the worldbuilding skill (and its reference files) from the repository path into a temporary folder and summarize what it does in one or two sentences. 2. Safety check: review the SKILL.md and scripts for anything suspicious (unexpected network calls, shell commands, credential harvesting). This repo should contain zero secrets in code, credentials only via the secure vault, allowed hosts declared in the SKILL.md. Verify that holds here; STOP on any red flag and tell me. 3. Install it as a skill: copy SKILL.md and its helper files into the agent's skills directory, in a folder named "worldbuilding". 4. Verify with no network calls: frontmatter valid, files in place. 5. Report what was installed, where, and what I still need to do myself (e.g. describe the world or setting you want to build). GitHub is optional: if I have a GitHub account or the gh CLI, you may use it; otherwise public access is fine. Never require it unless it's in the prerequisites above. Rules: don't touch anything outside the temp folder and the install target. If anything looks off, stop and ask me.
Questions
How do I install a build?
Every product page includes a copy-paste install prompt. Paste it into your Muse and it sets the build up for you — no manual configuration.
Where does my money go?
Straight to the seller. Skill Harbor never processes payments: checkout happens on the seller’s own page, usually Stripe.
What does the ✓ next to a creator’s name mean?
It means we confirmed the identity of the person behind the listing. It says nothing about the code itself — always check a build before installing it.
