Workflows that look like scientific writing will match `scientific-writing` / `literature-review` / `citation-management`; figure work will match `scientific-schematics` / `generate-image` / `infographics`; slide prep matches `scientific-slides` / `pptx`; etc. When a cluster scores high against two or three sibling skills the emitted composition recipe names them explicitly, so the user's future agent invocations use the optimized paths already documented in this repo.

Use whenever the user has bulk RNA-seq reads or quant output and wants a complete, reproducible differential-expression workflow — e.g. "analyze my RNA-seq", "FASTQ to DESeq2", "run nf-core/rnaseq", "STAR/Salmon quantification", "build a counts matrix for DESeq2", or "go from reads to differentially expressed genes and enriched pathways". Routes between an nf-core/rnaseq (Nextflow) path and a standalone STAR/Salmon path, and covers experimental design, strandedness, and QC gates. For single-cell RNA-seq use the scanpy skill instead.

 ## Source Coverage
 
 These references summarize the Pi documentation at `https://pi.dev/docs/latest` and every docs page found under it, as of Pi **0.84.2** (docs source: `packages/coding-agent/docs/` in `https://github.com/earendil-works/pi`, formerly `pi-mono`). They also cover the package pages for `pi-subagents`, `pi-mcp-adapter`, `pi-interview`, and `pi-web-access` at `https://pi.dev/packages/`, cross-checked against the published npm READMEs and package docs (`pi-web-access` 0.22.0, `pi-mcp-adapter` 2.25.0, `pi-subagents` 0.49.0, `pi-interview` 0.11.0). When exact API behavior matters, prefer the cited reference page and inspect installed TypeScript definitions under `node_modules/@earendil-works/pi-coding-agent/dist/` and `node_modules/@earendil-works/pi-ai/dist/`.

Use this skill whenever the user mentions PyHealth, MIMIC, eICU, OMOP, EHR modeling, clinical prediction, drug recommendation, sleep staging, medical code mapping, ICD/ATC codes, or any healthcare ML pipeline that fits the dataset → task → model → trainer → metrics pattern, even if "PyHealth" isn't named explicitly.

 Write minimal, idiomatic PyHealth. The library is opinionated; lean into its abstractions instead of reimplementing them in raw PyTorch. If you find yourself writing a custom training loop, ask whether `Trainer` would do the job — it almost always will, and it handles checkpointing, logging, and best-model selection for free.
 
 When the user has private MIMIC access, point them at the local CSV root; for demos and learning, the synthetic MIMIC-III bucket (`https://storage.googleapis.com/pyhealth/Synthetic_MIMIC-III/`) is fine and works without credentialing.

 **Final Note**: Grant writing is both an art and a science. Success requires not only excellent research ideas but also clear communication, strategic positioning, and meticulous attention to detail. Start early, seek feedback, and remember that even the best researchers face rejection—persistence and revision are key to funding success.
