Fact Check

Verify claims, statements, and information against reliable sources. Use when user asks to fact-check, verify, confirm, validate, or check the accuracy of an...

Security Scan

The skill is an instruction-only fact‑checking helper whose claimed purpose matches its content and it requests no credentials or installs; nothing in the bundle suggests incoherent or malicious behavior.

Purpose & Capability

Name, description, and SKILL.md align: instructions describe extracting claims, searching reliable sources, cross-referencing, and producing a verdict. The skill does not request unrelated credentials, binaries, or config paths.

Instruction Scope

Instructions are appropriately scoped to fact‑checking (identify claim, search sources, evaluate credibility, produce verdict). They are somewhat high‑level and assume the agent can query external sources (web, news, journals) but do not instruct the agent to read local files or access unrelated system state. Because source selection is left open, the agent's actual behavior will depend on the platform's browsing/API tools.

Install Mechanism

No install spec and no code files (instruction-only), so nothing is written to disk or downloaded during install — lowest install risk.

Credentials

No environment variables, credentials, or config paths are required. The declared needs are proportionate to the stated purpose. If the agent uses network tools or third‑party APIs to implement searches, those tools (and any credentials they need) are not specified by this skill.

Persistence & Privilege

always:false and user-invocable:true (defaults). The skill does not request persistent/system-wide privileges or configuration changes. Autonomous invocation is permitted by default but is not combined with other risky privileges.

Scan Findings in Context

[no_code_to_scan] expected: Regex scanner found nothing because this is an instruction-only skill (SKILL.md only). That is expected for a prose fact-checking helper.

Assessment

This skill appears coherent and low-risk, but consider these practical points before enabling: (1) it assumes the agent can access external sources — ensure you trust the agent's browsing/integration tools and their destination domains, (2) avoid sending sensitive or confidential statements for fact-checking because the skill may query third-party services, (3) if you need strict provenance, require the skill to cite primary sources with URLs and dates, and (4) if you want to limit source bias, configure an allowlist/denylist of domains or require specific databases (e.g., government or academic repositories). If any of those controls matter to you, request the skill author add explicit source/tool constraints or require specific credentials rather than leaving source selection open-ended.

Verify information through systematic source verification.

Workflow

1. Identify the claim - Extract the specific statement to verify
2. Search sources - Query reliable sources (news outlets, academic papers, official databases)
3. Cross-reference - Check multiple independent sources
4. Evaluate credibility - Assess source reliability and potential biases
5. Deliver verdict - Provide clear conclusion with evidence

Claim Types

Type	Approach	Trusted Sources
Statistics	Find original study/data	Government databases, peer-reviewed journals
Quotes	Locate primary source	Official transcripts, news archives
News events	Verify via multiple outlets	Major news organizations
Historical facts	Consult academic sources	Encyclopedias, scholarly publications
Product/company info	Check official sources	Company websites, SEC filings

Source Hierarchy

Tier 1 (Highest):

• Peer-reviewed journals
• Government databases/official statistics
• Court records, legal documents

Tier 2:

• Major news outlets (Reuters, AP, BBC, etc.)
• Established academic institutions
• Official company/organization statements

Tier 3:

• Social media (verify via other sources)
• Blogs, personal websites
• Unverified reports

Output Format

Claim: [exact statement]

Verdict: [TRUE / MOSTLY TRUE / UNVERIFIABLE / MOSTLY FALSE / FALSE]

Evidence:
- Source 1: [details]
- Source 2: [details]

Notes: [context, caveats, or additional context]

Constraints

• Never state certainty beyond what evidence supports
• Distinguish between "unverified" and "false"
• Provide sources, don't just claim verification
• Flag opinions vs facts clearly
• Update verdict if new evidence emerges
