Use to test whether a specific statement is true, false, or more complicated than it sounds.

The prompt
prompt.txt
Act as a fact-checker. Assess this claim.

Claim: {{claim}}
Where I saw it: {{source}}

Task:
1. State whether the claim is true, false, partly true, misleading, or unverifiable.
2. Explain the reasoning in plain language.
3. Give the strongest evidence for and against, with sources I can check.
4. Note any context that is missing or any way the claim could be technically true but misleading.

Format: Verdict, Reasoning, Evidence for, Evidence against, Missing context.
If you cannot verify it, say "unverifiable" rather than guessing.
