Factual Claim Verifier#
Use this skill when reviewing text, posts, captions, emails, scripts, articles, reports, summaries, technical documents, product copy, launch copy, educational content, or AI-generated answers that contain factual claims and may be published, sent, used for decisions, or shown to others.
Trigger examples:
- "Verify this text"
- "Fact-check this"
- "Check whether this is true"
- "Review this for factual errors"
- "Check this before I publish it"
- "Tell me if this is exaggerated"
Do not require exact trigger words. If a draft contains factual assertions that matter, use this skill.
Purpose#
Separate style from truth. Identify factual claims, verify them against reliable sources when needed, flag uncertainty or exaggeration, and propose safer wording before content leaves the workspace.
Mandatory Workflow#
- Read the full text before judging it.
- Extract factual claims that can be checked, including:
- Numbers, dates, prices, percentages, rankings, timelines.
- Names, titles, organizations, places, events.
- Product capabilities, availability, integrations, model names, or platform rules.
- Legal, medical, financial, investment, safety, copyright, or compliance claims.
- Technical claims, benchmarks, comparisons, and cause-effect statements.
- Separate facts from opinions. Opinions do not need verification unless they are presented as objective facts.
- Verify important or risky claims using, in priority order:
- User-provided source material.
- The original document, transcript, thread, or linked material.
- Primary sources: official docs, policy pages, papers, laws, product pages, filings, or direct source material.
- Web search for current or changing facts.
- Careful reasoning only when no source access exists, clearly labeled as such.
- Classify each important claim.
- Flag errors, exaggerations, missing nuance, unsupported claims, and invented or weak citations.
- Suggest concrete corrections.
- Return a publication-readiness verdict.
Claim Categories#
Use these categories:
- Verified: clearly supported by available evidence.
- Mostly correct: broadly true but needs nuance, scope, or updated wording.
- Unsupported / not verifiable: insufficient evidence from available sources.
- Exaggerated: based on something real but stated too strongly.
- Likely false: contradicted by available evidence or highly unlikely.
- Opinion / not factual: subjective judgment that does not require factual verification.
Source Rules#
- Browse for current facts, prices, laws, platform rules, product features, availability, or anything with more than a small chance of changing.
- Prefer primary sources.
- Do not invent citations.
- Keep quotes short and compliant.
- If a claim cannot be verified, say that. Do not mark it false merely because evidence is missing.
- For high-stakes claims, be conservative and recommend verification from authoritative sources.
Long Text Rule#
If the text is long, prioritize claims with the highest risk to credibility, safety, legality, finances, publication quality, or brand trust. Say explicitly that the review focused on the highest-risk claims.
Return the report in the same language as the reviewed text unless the user asks otherwise.
Use this structure:
markdown
**Verdict:** ready / publish with minor changes / revise before publishing / do not publish yet
**Summary**
[Brief overall assessment.]
**Claim Review**
| Claim | Classification | Evidence or Reason | Suggested Correction |
|---|---|---|---|
| [claim] | [category] | [source note or reason] | [rewrite or -] |
**Main Risks**
- [highest-impact issue]
- [next issue]
**Required Corrections**
- [specific correction]
**Safer Rewrite**
[Only rewrite the problematic passages unless the user asks for the full corrected text.]
**Residual Uncertainty**
[What still needs manual or primary-source confirmation, if anything.]
Verdict Meanings#
- ready: no material factual issues found.
- publish with minor changes: mostly fine, but wording needs small corrections or caveats.
- revise before publishing: material claims need correction, sourcing, or stronger nuance.
- do not publish yet: contains likely false, high-risk, or unsupported claims that could mislead or harm credibility.
Risk Language To Flag#
Pay special attention to:
- Guaranteed results.
- Fake scarcity or urgency.
- Investment or income promises.
- Medical, legal, financial, tax, or safety certainty.
- Copyright or ownership claims.
- Claims about AI tools, models, pricing, platform access, or integrations.
- Comparative claims about competitors.
- Statistics without source or methodology.
Behavior Rules#
- Be useful and direct, not alarmist.
- Preserve the user's intent when suggesting safer wording.
- Do not rewrite opinions as facts.
- Do not change numbers, conditions, names, or promises unless correcting an identified issue.
- Do not publish, send, upload, approve, or make external account changes.
- For public channels, combine this review with an approval package before publication.
Safety#
This skill reviews and rewrites only. It does not authorize publication, external messages, financial action, or account changes.
