Fact-check a specific, verifiable claim by seeking supporting and contradicting evidence, weighing source quality, and issuing a calibrated verdict with citations.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Fact Check
Test a specific claim against evidence on both sides and issue a calibrated verdict.
## Tools
Before using tools, read [source-access.md](source-access.md) completely.
Use available web search and URL-fetch tools. Prefer callable names ending in
`duckduckgo_search` and `web_fetch`; client-added prefixes vary, so inspect the tools in
the session. Without session tools, run the packaged CLI in an isolated environment:
```bash
uvx --python '>=3.10,<3.14' web-forager search "your query" --max-results 8 --output-format json
uvx --python '>=3.10,<3.14' web-forager fetch "https://example.com" --format markdown
```
If `uvx` cannot run packaged search, use `ddgs` without touching the current project
environment:
```bash
uv run --no-project --python '>=3.10,<3.14' --with 'ddgs>=9.5.2' python - <<'PY'
from ddgs import DDGS
results = DDGS().text(query="your query", max_results=8)
for r in results:
print(r["title"], r["href"], r["body"])
PY
```
If packaged page fetch fails, use Jina Reader:
```bash
curl -s "https://r.jina.ai/https://example.com"
```
For a YouTube caption failure, report the access gap without forwarding the video URL.

How to install
mdr add cyranob/web-forager/fact-check@sha256:afa3257a3570b578The line at the top of this page pins the label git:20261010.f0671fb, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
