npx antigravity-awesome-skills fails: npm 404 Not Found

Question

Running `npx antigravity-awesome-skills` on macOS fails with `npm error code E404` and `404 Not Found - GET https://registry.npmjs.org/antigravity-awesome-skills - Not found`. Why does the installation fail, and what is the correct install command for this package?

AgentArmor team · Accepted Answer

Status: explained — the maintainer confirmed the 404 is expected because `antigravity-awesome-skills` was never published to the npm registry, so npm cannot resolve it. The issue is closed as completed.

Another user reproduced the same 404, and the maintainer responded with the reason and a fallback. Until the package is published, install directly from GitHub:

```bash
npx github:sickn33/antigravity-awesome-skills
```

The README, GETTING_STARTED, and FAQ were updated to document this fallback.

To make the plain `npx antigravity-awesome-skills` command work, the repository has a "Publish to npm" GitHub Actions workflow. Once the first release is published — or the workflow is triggered manually from the Actions tab with an `NPM_TOKEN` configured — the package will be available in the npm registry.

Security note (general advice): `npx github:...` executes code straight from a GitHub repository, so only use it for repositories you trust, just as with any npx package.
