- Geo Seo ClaudeAudit and optimize content for SEO, GEO (generative engine optimization), and AEO (answer engine optimization). Use when user asks to "audit SEO", "check search visibility", "optimize for AI search", "generate schema markup", "validate metadata", "extract keywords", "optimize for Perplexity/ChatGPT/Gemini", "check Open Graph tags", "submit to IndexNow", or mentions SEO, GEO, AEO, or search optimization. Do NOT use for creating new content from scratch or image optimization.Votes: 0GitHub stars: 158
- Alterlab Survey AnalysisAnalyzes complex-sample survey data with design-based inference — declares a survey design (weights, strata, PSUs/clusters, FPC) before estimating means, totals, proportions, ratios, and quantiles, computes design-adjusted standard errors via Taylor linearization or replicate weights (BRR, Jackknife, Bootstrap), calibrates with post-stratification / raking / GREG, and fits design-adjusted GLMs (linear, logistic, Poisson). Uses samplics (stable Python), the emerging svy successor, or the field...Votes: 0GitHub stars: 158
- Alterlab SnaApplies social-network-analysis method discipline to relational data — degree/betweenness/closeness/eigenvector centrality and PageRank, community detection (Louvain and greedy-modularity native in networkx, Leiden via igraph), and inferential network models (ERGM) — choosing the measure that matches the substantive question and the right dependence assumptions, then routing computation to the existing networkx (and igraph/R) tooling. Use when the request mentions social network analysis, cen...Votes: 0GitHub stars: 158
- Alterlab Sem PsychometricsFits and evaluates measurement models — confirmatory factor analysis, full structural equation models, exploratory factor analysis, item response theory, and multi-group measurement invariance — using the verified Python stack: semopy (model syntax =~ / ~ / ~~, Model.fit, inspect(std_est=True), calc_stats for CFI/TLI/RMSEA), factor_analyzer (EFA, KMO, Bartlett, ConfirmatoryFactorAnalyzer), and pingouin/girth, computing McDonald's omega from standardized loadings and judging fit against Hu & B...Votes: 0GitHub stars: 158
- Alterlab ScgptApply the scGPT single-cell foundation model (Cui 2024) to annotate and embed cells — zero-shot and fine-tuned cell-type annotation, gene/cell embeddings, batch integration, and gene-regulatory / perturbation inference from AnnData. Use when annotating cell types with a pretrained foundation model, generating scGPT embeddings, integrating batches with a transformer, or running zero-shot single-cell inference on an h5ad. For probabilistic latent models (scVI/scANVI) prefer alterlab-scvi-tools;...Votes: 0GitHub stars: 158
- Alterlab QcaRuns Qualitative Comparative Analysis — crisp-set (csQCA), multi-value (mvQCA), and fuzzy-set (fsQCA) — for small-to-medium-N configurational research: calibrating raw data into set membership, building and refining a truth table, and Boolean minimization into conservative / parsimonious / intermediate solutions with consistency and coverage. Because there is no maintained Python QCA library, it shells out to R's QCA package (calibrate, truthTable, minimize) via Rscript and documents that dep...Votes: 0GitHub stars: 158
- Alterlab Missing DataHandles missing data with principled methods — forces an explicit MCAR / MAR / MNAR mechanism statement, then applies multiple imputation by chained equations (MICE) with Rubin's-rules pooling of estimates and standard errors, or full-information maximum likelihood (FIML) where a likelihood/SEM model applies. Uses statsmodels MICE / MICEData in Python or the field-standard R mice via Rscript, and warns that single (mean/regression) imputation and scikit-learn's IterativeImputer return one com...Votes: 0GitHub stars: 158
- Alterlab Causal InferenceEstimates causal effects from observational and quasi-experimental data — difference-in-differences, instrumental variables, regression discontinuity, panel fixed effects, propensity-score / doubly-robust methods, and heterogeneous treatment effects (CATE) — using the verified Python stack: statsmodels and linearmodels (PanelOLS, IV2SLS), pyfixest (feols, event studies, Sun-Abraham, did2s), DoWhy (identify -> estimate -> refute), EconML (LinearDML, CausalForestDML, DRLearner), and rdrobust fo...Votes: 0GitHub stars: 158
- Alterlab Abm MesaBuilds agent-based models of social systems with Mesa 3 — the current AgentSet API (model.agents.shuffle_do('step'), auto-assigned unique_id, mandatory super().__init__(seed=...)), cell spaces (mesa.discrete_space OrthogonalMooreGrid / classic mesa.space grids), the DataCollector, batch_run parameter sweeps, and SolaraViz — for emergence, segregation, diffusion, opinion dynamics, and cooperation models. It uses the Mesa 3.x API (the old mesa.time schedulers like RandomActivation are removed) ...Votes: 0GitHub stars: 158

- PapersLevanta papers científicos sobre metodologias de IA aplicadas à medicina publicados nos últimos 7 dias, sobre um tópico específico que o usuário fornece. Use esta skill SEMPRE que o usuário pedir "/papers", "papers da semana", "o que saiu essa semana sobre [tópico]", "varrer arxiv/pubmed/medrxiv", "levantamento semanal de papers", "novidades em IA médica", "papers recentes sobre [tema]", "o que foi publicado essa semana em IA médica", "semana de [tópico]", "últimos papers sobre IA em saúde". ...Votes: 0GitHub stars: 2
- Lab ExpRoda um experimento preditivo clinico de ponta a ponta no padrao do laboratorio, da auditoria de vazamento ate o zip e o repositorio privado. Comeca sempre pela auditoria que decide se o experimento faz sentido (momento da predicao, censura disfarcada de desfecho, variavel que sozinha da AUC alta demais), depois monta o pipeline com Boruta dentro do fold, sete modelos com regra de desempate declarada antes, limiar fora da amostra, IC por bootstrap e calibracao, e entrega notebook do Colab, no...Votes: 0GitHub stars: 2
- Fused RuntimeWhat a Fused UDF can import and shell out to at run time — the Python packages and versions in the realtime and batch images, system binaries, DuckDB extensions, and how to get a package that isn't installed. Use before importing a library in a UDF, when a UDF fails with ModuleNotFoundError or a version-specific API error, or when choosing between libraries for a UDF.Votes: 0GitHub stars: 5

- Regime ScanScan the whole US market once a day for trend direction and sentiment turns. Folds index trend, breadth, VIX term structure, credit spreads, and defensive rotation into one 🟢/🟡/🔴 state plus divergence flags, logging each day so the slope (the real turn signal) shows across runs. Use to gauge market direction and whether sentiment is rolling over (index near highs but internals weakening) before adding risk vs raising cash. Triggers on "scan the market", "market trend", "sentiment turn", "m...Votes: 0GitHub stars: 19
- Sql ReviewProve an app's numbers against live Snowflake and leave a record a person signs. Builds or repairs the app's sql_review/ page files, checks objects, grants and DDL drift, runs every section as aggregates, has reviewer agents judge the logic, drops findings the evidence does not support, and writes the committed review log. Use when the user says "review the SQL", "are these numbers right", "trace the data", "audit the lineage", before a release or deploy, or from /review-app --sql. It spends ...Votes: 0GitHub stars: 3
