A skill is a portable skill.md file — YAML frontmatter plus a markdown body — that you drop into Claude Code, Cursor, Windsurf, Copilot, or any other AI tool that reads project instructions. Every entry here downloads in the format you need, and carries a community-verified compatibility matrix showing which tools it actually works with.

Literature Map Builder
Cluster a set of papers into a topic map with methodology and findings per cluster, then surface the whitespace where nobody is working yet.

Turn a list of competitor URLs into a normalized feature and pricing matrix you can paste into a deck — without the 'plan names mean different things at each company' problem.
Statistical Claim Checker
Validate every quantitative claim in an article against the source data it cites, flagging numbers that are unsupported, outdated, or selectively quoted.
Academic Paper Review
Structured critical review of a paper (method, claims, threats to validity) in the voice of a third reviewer.
Prompt A/B Evaluator
Run two prompt variants against a fixed test set, score with a rubric LLM, and tell you which wins (and why).
