- package.json: yaml in devDependencies, repo url/bin from npm pkg fix
- README, GETTING_STARTED, FAQ: fallback npx github:sickn33/antigravity-awesome-skills on 404
- publish-npm.yml: workflow on release published + workflow_dispatch
- MAINTENANCE: bump package.json, publish to npm (manual + NPM_TOKEN CI)
- release_cycle.sh: catalog step, version check, npm publish reminder
- ISSUE_49_COMMENT.md: suggested reply for issue #49

+Suggested comment for [Issue #49](https://github.com/sickn33/antigravity-awesome-skills/issues/49). Paste this on the issue:
+
+---
+
+The 404 happens because the package wasn’t published to npm yet. We’ve addressed it in two ways:
+
+1. **Publish to npm** – We’re set up to publish so `npx antigravity-awesome-skills` will work after the first release. You can also trigger a manual publish via the “Publish to npm” workflow (Actions tab) if you have `NPM_TOKEN` configured.
+
+2. **Fallback** – Until then (or if you hit a 404 for any reason), use:
+   ```bash
+   npx github:sickn33/antigravity-awesome-skills
+   ```
+   The README, GETTING_STARTED, and FAQ now mention this fallback.
+
+Thanks for reporting.

 1.  **Run Full Validation**: `python3 scripts/validate_skills.py --strict`
 2.  **Update Changelog**: Add the new release section to `CHANGELOG.md`.
-3.  **Bump Version**: Update header in `README.md`.
+3.  **Bump Version**:
+    - Update `package.json` → `"version": "X.Y.Z"` (source of truth for npm).
+    - Update version header in `README.md` if it displays the number.
+    - One-liner: `npm version patch` (or `minor`/`major`) — bumps `package.json` and creates a git tag; then amend if you need to tag after release.
 4.  **Tag Release**:
     ```bash
     git tag -a v4.0.0 -m "V4 Enterprise Edition"
     git push origin v4.0.0
     ```
+5.  **Publish to npm** (so `npx antigravity-awesome-skills` works):
+    - **Option A (manual):** From repo root, with npm logged in and 2FA/token set up:
+      ```bash
+      npm publish
+      ```
+      You cannot republish the same version; always bump `package.json` before publishing.
+    - **Option B (CI):** On GitHub, create a **Release** (tag e.g. `v4.6.1`). The workflow [Publish to npm](.github/workflows/publish-npm.yml) runs on **Release published** and runs `npm publish` if the repo secret `NPM_TOKEN` is set (npm → Access Tokens → Granular token with Publish, then add as repo secret `NPM_TOKEN`).
