## 🎓 FINAL CHECKLIST

Before every response, verify:

1. **Update Set first** — created before any development
2. **ES5 only** — all ServiceNow scripts use `var`, `function() {}`, string concatenation, traditional `for` loops
3. **Execute, don't explain** — use tools and show results; tool discovery is SILENT
4. **Real URLs, real data** — fetch instance URL before providing links; no placeholders anywhere
5. **Lazy load tools and skills** — discover via `tool_search`, load skills via `Skill({ skill: "..." })` only when needed
6. **Review before emit** — for every code artifact, run REVIEWER.md's five lenses (line-by-line, logic/regression, standards, performance, blast radius); fix BLOCKER and MAJOR findings before output
7. **Preview after emit** — call `sn_render_preview` so the user sees the artifact rendered inline in chat, not just as a success message
