## Articles Written

### "How to Build a Virtual Cell" ✅
- **File:** `~/.openclaw/workspace/articles/2026-03-09-how-to-build-a-virtual-cell.md`
- **Length:** ~1,800 words
- **Status:** Draft complete, awaiting Bo's review/approval before posting
- **Sections:** Why (drug failures) → scRNA-seq data foundation → what foundation models learn → perturbation challenge → data diversity bottleneck → multi-omics → applications → honest caveats → path forward

- **Bio at end:** "Bo Wang is a co-creator of scGPT and a researcher at Xaira Therapeutics..."
- **Post command when ready:** `bun ~/.openclaw/workspace/skills/baoyu-post-to-x/scripts/x-article.ts ~/.openclaw/workspace/articles/2026-03-09-how-to-build-a-virtual-cell.md`

## Assessments

### XHS shadow ban detector tweet (@xxx111god)
- Bo asked to assess and integrate; did both
- Technique: CDP intercept of XHS creator API `level` field
- Recommendation: install (low risk, read-only, useful if posting to XHS)
- Bo approved → built check_shadowban.py
