What Coverage Check does

Analyze news coverage to distinguish between many independent sources and a single source reprinted many times. Queries GDELT for articles, groups by headline similarity, and estimates the number of distinct origins behind a claim.

Coverage Check is cataloged under Quality on DirSkills. Coverage Check comes from a repository tagged agent-skills, ai-agents, claude-code, content-analysis and fact-checking.

Documentation

README

Excerpt

coverage-check

Ten URLs are not ten sources. This turns "lots of outlets reported it" into a number you can defend.

When to reach for it

During claim verification, when a claim looks corroborated by volume — a pile of search results all saying the same thing. That pattern has two very different causes:

Many newsrooms independently established the fact → genuinely strong evidence
One press release, wire story, or study got reprinted 40 times → one source

Search results look identical in both cases. This tells them apart.

Usage

uv run scripts/coverage.py "<query>" [--timespan 3m] [--max 250] [--sort dateasc] [--timeout 120] [--json]
