Claude Skills by thedixitjain

Use when controlling the length of a pure-mathematics manuscript for Annals of Mathematics — math papers may be long, but every section must be necessary; this skill cuts bloat and padding while keeping the proof complete and gap-free. Late-stage; run after the proof and architecture are fixed.

Use when laying out the proof strategy of a pure-mathematics manuscript for Annals of Mathematics — the architecture of the argument, the key lemmas and propositions, the novel technique, and where the difficulty lies. Designs and exposes the proof plan; does not check final correctness line-by-line (see anmath-referee-strategy).

Data structure for annotated matrices in single-cell analysis. Use when working with .h5ad files or integrating with the scverse ecosystem. This is the data format skill—for analysis workflows use scanpy; for probabilistic models use scvi-tools; for population-scale queries use cellxgene-census.

Use BEFORE responding when the user's request shows pressure to validate or agree (\"tell them what they want\", \"make them happy\", \"convince them\"), manufactured urgency (artificial deadline), authority appeals (citing investors, advisors, lawyers, experts), demands to certify without evidence, requests to soften an honest assessment, \"help me convince X of Y\" or \"how do I get X to agree\" framings where Y is dubious, asking you to commit to numbers beyond data, framing a wrong assump...
