-### Q: Why shouldn't I just copy all files?
+### Q: Do I need to install all 250+ skills?
 
-You can! But 250+ files might clutter your context window.
-We recommend using **Starter Packs** (`docs/BUNDLES.md`) to install only what you need for your specific role.
+**No!** When you clone the repository, all skills are available, but your AI only loads them when you explicitly invoke them with `@skill-name`.
+It's like having a library - all the books are there, but you only read the ones you need.
+_Pro Tip: Use [Starter Packs](docs/BUNDLES.md) to install only what matches your role._
+
+### Q: Where should I install the skills?
+
+The universal path is `.agent/skills/`:
+
+```bash
+git clone https://github.com/sickn33/antigravity-awesome-skills.git .agent/skills
+```

+
+### Q: How do I invoke a skill?
+
+In your AI chat (Claude, Cursor, etc.), just use the `@` mention:
+
+```
+@brainstorming help me design a todo app
+```
+
+### Q: My AI assistant doesn't recognize skills. Why?
+
+1.  **Wrong Path**: Did you clone to `.agent/skills/`? Check your tool's settings.
+2.  **Restart Needed**: Some tools (like Cursor) need a restart to index new files.
+3.  **Typos**: Check `ls .agent/skills/` to see the exact folder name.
+
+### Q: What if a skill gives bad code?
+
+Please [Open an Issue](https://github.com/sickn33/antigravity-awesome-skills/issues)!
+Describe what happened and which skill was responsible. We update skills regularly to fix hallucinations.
