Example 1: Article citing a vendor study
User: "bias check https://news.example.com/some-article-citing-a-vendor-survey"
→ Check intent
→ The cited vendor study is located and read alongside the article
→ Report covers the vendor conflict of interest, sample and question-design biases, and the headline-vs-source swap, then the supported-vs-editorialized split
Example 2: Raw paste of a study abstract
User: "bias check this abstract: [pastes 4 paragraphs from a paper]"
→ Check intent
→ Layers 1 and 2 only (funding disclosure, sample, methodology, conflict of interest); Layer 3 is skipped with a note because the input IS the primary source
→ The report says when the abstract is too thin to assess methodology (publication availability bias)
Example 3: File path
User: "bias check ~/Downloads/some-report.pdf"
→ Check intent
→ Upstream sources the report cites are fetched where possible
→ Three-layer report with specifics
