Query Strengthening
If initial query returns poor results:
- Add version: "React 19 useOptimistic" vs "React useOptimistic"
- Add year: "FastAPI middleware 2024" vs "FastAPI middleware"
- Add "official": "Next.js official docs app router"
- Be more specific: "Prisma findMany where clause" vs "Prisma queries"
Verification Checklist
After grounding with Exa:
| Check | Pass If |
|---|
| Source | Official docs or reputable repo |
| Freshness | Updated within 12 months |
| Version | Matches your dependency |
| Completeness | Full import + usage pattern |
| Status | Not deprecated |
Recording Results
Track grounding status in your work:
## Grounding Status
| Pattern | Query | Source | Status |
|---------|-------|--------|--------|
| `@model_validator` | "Pydantic v2 2024" | docs.pydantic.dev | ✅ Verified |
| `useOptimistic` | "React 19 2024" | react.dev | ✅ Verified |
Status values:
- ✅ Verified — Matches current docs
- ⚠️ Changed — API changed, updated approach
- ❌ Deprecated — Found alternative
- ❓ Unverified — Couldn't confirm, flagged
