# verify-claim

Verify factual claims against live data before using them in responses, calculations, or decisions. Returns structured verdicts with confidence scores and current truth values.

When to Activate

Use this skill whenever:

**Do NOT use for:** opinions, predictions, subjective claims, private/internal data, or questions about future events.

Workflow

Step 1: Extract the claim

Identify the specific factual assertion. Be precise — "Bitcoin price is above $60,000" is better than "Bitcoin is expensive."

Step 2: Check via MCP tool (preferred)

If `@agentutil/verify-mcp` is available as an MCP tool, use it directly:

verify_claim({ claim: "The USD to EUR exchange rate is 0.92" })

Step 3: Fall back to HTTP

If no MCP tool is available, call the API:

curl -X POST https://verify.agentutil.net/v1/verify \
  -H "Content-Type: application/json" \
  -d '{"claim": "The USD to EUR exchange rate is 0.92"}'

Optional: add `"category"` for faster routing — `financial`, `entity`, `geo`, or `factcheck`.

Step 4: Interpret the verdict

| Verdict | Confidence | What to do |

|---------|------------|------------|

| `confirmed` | > 0.9 | Safe to use. Cite `current_truth` as the verified value. |

| `confirmed` | 0.7-0.9 | Likely correct but note the uncertainty to the user. |

| `stale` | any | The claim WAS true but data has changed. Use `current_truth` instead. Tell the user: "That was previously correct, but the current value is X." |

| `disputed` | any | Sources disagree. Present both sides — do NOT pick one. Say: "Sources conflict on this — [source A] says X while [source B] says Y." |

| `false` | > 0.8 | Contradicts current data. Correct it: "Actually, the current value is X." |

| `false` | < 0.8 | Likely wrong but not certain. Flag it: "This doesn't match current data (X), but confidence is moderate." |

| `unknown` | any | Could not verify. Say so honestly — do NOT guess. |

Step 5: Act on the result
