## Decision tree

1. **Is the full skill already installed?**
   Check whether the skill at this location still has a `das:` block:
   - Global: `grep -q "^das:" ~/.agents/skills/cloudflare-web-perf/SKILL.md 2>/dev/null && echo "pointer" || echo "installed"`
   - Project: `grep -q "^das:" .agents/skills/cloudflare-web-perf/SKILL.md 2>/dev/null && echo "pointer" || echo "installed"`
   - No `das:` block → full skill installed, invoke it and proceed
   - `das:` block present → go to step 2

2. **Detect scope, then install:**

   To detect scope:
   ```bash
   [ -e ~/.agents/skills/cloudflare-web-perf ] && echo "global" || echo "project"
   ```

   **Global** (installed with `-g`):
   ```bash
   npx skills add cloudflare/skills --skill cloudflare-web-perf -g -y
   ```

   **Project** (installed without `-g`):
   ```bash
   npx skills add cloudflare/skills --skill cloudflare-web-perf -y
   ```
   > **Claude Code:** send either command as a chat message starting with `!` to run it without leaving the conversation.
