Review and validate claims using counter-hypothesis testing. Use when verifying technical content, checking references, validating API endpoints, or performing quality assurance on deliverables.
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
# Skill: Fact Checking
## Context
Codifies the challenger agent review output format and methodology so any agent performing fact-checking or review produces consistent, structured output.
## Pattern
### Review Methodology
For every claim or deliverable under review:
1. Ask: "What evidence supports this? What would disprove it?"
2. Generate counter-hypotheses and test them against available data
3. Verify URLs, package names, API endpoints, and external references actually exist
4. Flag confidence levels: ✅ Verified, ⚠️ Unverified, ❌ Contradicted
### Review Output Format
When reviewing another agent's work, use this template:
```
### Fact Check — {deliverable name}
**Claims verified:** {count}
**Issues found:** {count}
| # | Claim | Status | Evidence/Notes |
|---|-------|--------|---------------|
| 1 | {claim} | ✅/⚠️/❌ | {supporting or contradicting evidence} |
**Counter-hypotheses tested:**
- {alternative explanation + result}
**Verdict:** {PASS / PASS WITH NOTES / NEEDS REVISION}
```
### Confidence Levels
- ✅ **Verified** — evidence confirms the claim
- ⚠️ **Unverified** — cannot confirm or deny; suggest verification method

How to install
mdr add bradygaster/squad/fact-checking@sha256:f03e598d679065e7The line at the top of this page pins the label v1.0.0, 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.
