Source Credibility Scorer Skill
Use when: evaluating whether a source is trustworthy, comparing multiple sources, or when research-reporter findings need credibility validation.
Score a single source
node ${SOURCE_SCORER_HOME:-$HOME/projects/source-scorer}/score.cjs --url "https://..." [--content "text"] [--claim "specific claim"]
Score with JSON output (for piping)
node ${SOURCE_SCORER_HOME:-$HOME/projects/source-scorer}/score.cjs --url "https://..." --json
Score multiple URLs
echo -e "https://url1\nhttps://url2" > /tmp/urls.txt
node ${SOURCE_SCORER_HOME:-$HOME/projects/source-scorer}/score-batch.cjs --urls-file /tmp/urls.txt
Check domain tier
node ${SOURCE_SCORER_HOME:-$HOME/projects/source-scorer}/domain-tier.cjs example.com
Auto-integration
research-reporter's add-finding.cjs auto-scores when --url is provided.
The credibility score is saved with the finding and confidence is averaged with the user-provided value.
Score interpretation
80–100 🟢 High credibility — use with confidence
55–79 🟡 Moderate — use, but cross-reference
30–54 🟠 Low credibility — flag as unverified
0–29 🔴 Unreliable — avoid or explicitly mark as speculation
Scoring model (0–100 total)
| Factor | Max | Notes |
|---|
| Domain tier | 35 | docs.*/gov/edu=35, major tech=28, pubs=20, Q&A=12 |
| HTTPS | 10 | URL starts with https:// |
| Content depth | 15 | Word count + citation/reference patterns |
| Cross-reference | 20 | Claim found in knowledge base from other docs |
| Consistency | 20 | Default 20 (reserved for research-reporter) |
Key signals that boost score
docs.* subdomains, .gov, .edu: highest tier (Tier 1, 35pts)- HTTPS: required for any real trust (+10pts)
- Long content with references: shows substantive work (+up to 15pts)
- Claim appears in knowledge base from other sources: strong confirmation (+20pts)
