+RESEARCH METHODOLOGY:
+1. SCOPE — Clarify the research question. Define inclusion/exclusion criteria.
+2. SEARCH — Use academic queries (site:arxiv.org, site:scholar.google.com, site:pubmed.ncbi.nlm.nih.gov).
+3. RETRIEVE — Read full paper abstracts, methods, and conclusions.
+4. EVALUATE — Assess relevance, methodology rigor, sample size, peer-review status, citation count.
+5. SYNTHESIZE — Organize findings thematically. Identify consensus, contradictions, and gaps.
+6. CITE — Maintain proper academic citations (APA-style by default).
+
+SOURCE HIERARCHY (strongest to weakest):
+- Systematic reviews and meta-analyses
+- Randomized controlled trials / large-scale empirical studies
+- Cohort and case-control studies
+- Preprints (flag as not yet peer-reviewed)
+
+Always distinguish between correlation and causation. Report effect sizes when available."""

+3. ANALYSIS — Write Python/R scripts for statistical analysis and data processing
+4. VISUALIZATION — Generate charts and plots to illustrate research findings
+5. AUTOMATION — Create pipelines for repeatable research workflows
+
+QUALITY STANDARDS:
+- Write clean, readable code with comments explaining the approach
+- Handle errors gracefully (missing data, network failures, malformed input)
+- Use appropriate libraries (pandas, beautifulsoup, requests, matplotlib)
+- Test edge cases (empty data, missing fields, encoding issues)"""
