Input

$ARGUMENTS

The input should be a path to an article file (e.g., _includes/ru/tax-optimization/rent.md).

Instructions

Phase 1: Read and Extract Facts

1. Read the article from the specified path

2. Extract all verifiable claims, including:

   • Numbers: percentages, amounts, limits, thresholds (e.g., "IVA 21%", "315€/month", "60,000€ threshold")
   • Deadlines: filing dates, registration periods, waiting times (e.g., "quarterly by 20th", "within 30 days")
   • Conditions: eligibility requirements, prerequisites (e.g., "only for first-time autonomos", "requires 3 years of residence")
   • Legal references: laws, regulations, articles (e.g., "Ley 20/2007", "Art. 96 LIRPF")
   • Procedures: steps, requirements, document lists
   • Rates and calculations: tax rates, social security contributions, formulas
   • Official terminology: correct names of forms, institutions, programs

3. Create a list of facts to verify with context from the article

Phase 2: Verify Against Official Sources

4. Use WebSearch to verify each fact against authoritative sources:

   Primary sources (MUST use when relevant):

   • Agencia Tributaria (sede.agenciatributaria.gob.es) - taxes, IVA, IRPF, models
   • Seguridad Social (seg-social.es) - contributions, quotas, benefits
   • BOE (boe.es) - laws, royal decrees, official regulations
   • Ministerio de Trabajo - labor regulations
   • Banco de España - banking regulations

   Secondary sources (for additional context):

   • Official bank websites
   • Professional associations (colegios profesionales)
   • Recognized legal/tax advisory firms with cited sources

5. For each fact, document:

   • The exact claim from the article
   • What the official source says
   • The URL of the source
   • Whether it matches, partially matches, or contradicts

Phase 3: Legal Verification

6. For any legal references:

   • Verify the law/article number is correct
   • Check if it's still in force (not derogated or modified)
   • Confirm the interpretation in the article matches the legal text
   • Use BOE or official legal databases

7. Check for outdated information:

   • Tax rates and limits often change annually
   • Social security contributions update yearly
   • Verify current year values, not historical ones

Phase 4: Generate Report

8. Create a comprehensive fact-check report with the following structure:

## Fact-Check Report: [Article Name]

What to Flag as ⚠️ Partial Discrepancy:

• Minor differences in wording that don't change meaning
• Missing details that could be helpful
• Simplifications that omit edge cases

What to Flag as ❌ Incorrect:

• Wrong numbers, rates, or percentages
• Outdated information (old rates, repealed laws)
• Incorrect deadlines
• Wrong form numbers or procedure steps
• Misinterpretation of legal requirements

Personal Experience Claims:
