Quick start

# 1. Save your API token (get one at haluguard.com)
haluguard auth login

# 2. Verify a file
haluguard check report.md

# 3. Or pipe input
echo "Microsoft was founded in 1981 by Bill Gates." | haluguard check

# JSON output for scripts / CI

# Exit non-zero only above a confidence threshold (useful in CI)
haluguard check report.md --threshold 0.7

Output

Human-readable by default:

✗ HALLUCINATIONS    severity=clear  score=0.95  claims=1/2  latency=4ms
verdict source: data_contradicted

  [CONTRADICTED] high · wikidata
    claim:    Microsoft was founded in 1981
    evidence: Wikidata confirms Microsoft was founded in 1975
    source:   https://www.wikidata.org/wiki/Q2283
    fix:      1975

--json returns the raw API response (verdict, severity_tier, score, findings, etc).
