-   ```
+- Need to ship a feature now: `Essentials` + one domain pack (`Web Wizard`, `Python Pro`, `DevOps & Cloud`).
+- Need reliability and hardening: add `QA & Testing` + `Security Developer`.
+- Need product growth: add `Startup Founder` or `Marketing & Growth`.
 
-2. **Or use the installer:**
-   ```bash
-   npx antigravity-awesome-skills
-   ```
+### 2) Start with 3-5 skills, not 20
 
-### Using Skills
+Pick the minimum set for your current milestone. Expand only when you hit a real gap.
 
-Once installed, reference skills in your AI assistant:
+### 3) Invoke skills consistently
 
-- **Claude Code**: `>> @skill-name help me...`
+- **Claude Code**: `>> /skill-name help me...`
 - **Cursor**: `@skill-name` in chat
