**Risk Level Reference**:

| riskLevel | riskLevelEnum | Action | Description |
|-----------|---------------|--------|-------------|
| 0-1 | LOW | Proceed with caution | Lower risk detected, but NOT guaranteed safe. DYOR. |
| 2-3 | MEDIUM | Exercise caution | Moderate risks detected, review risk items carefully |
| 4 | HIGH | Avoid trading | Critical risks detected, high probability of loss |
| 5 | HIGH | Block transaction | Severe risks confirmed, do NOT proceed |

**IMPORTANT**: LOW risk does NOT mean "safe." Audit results are point-in-time snapshots. Project teams can modify contracts or restrict liquidity after purchase. These risks cannot be predicted in advance.

**Response Handling**:

- If `hasResult=false` OR `isSupported=false`:
  → Reply: "Security audit data is not available for this token on this chain."
  → Do NOT show `riskLevel`, `riskLevelEnum`, or `riskItems` (data is unreliable when either field is false)
  → You may suggest the user verify the contract address and chain, or try again later
- If `hasResult=true` AND `isSupported=true`:
  → Show the full audit result including risk level, tax info, and all risk items
  → Apply the Risk Level Reference table above for actionable guidance

## User Agent Header

Include `User-Agent` header with the following string: `binance-web3/1.4 (Skill)`

## Notes

1. All numeric fields are string format, convert when using
2. Audit results are ONLY valid when `hasResult: true` AND `isSupported: true`
3. `riskLevel: 5` means transaction should be blocked; `riskLevel: 4` is high risk
4. Tax thresholds: >10% is critical, 5-10% is warning, <5% is acceptable
5. Generate unique UUID v4 for each audit request
6. Only output security check risk flags, do NOT provide any investment advice 
7. Always end with disclaimer: `⚠️ This audit result is for reference only and does not constitute investment advice. Always conduct your own research.`
