lazyisefficient Bundle Game BalancerUse when tuning the numbers in a game — economy curves, progression rates, difficulty pacing, drop tables, win/loss odds, time-to-X targets, and currency velocities. Triggers on "balance pass", "tune the economy", "progression curve", "difficulty curve", "drop rate", "XP curve", "TTK", "time-to-content", "balance the economy", "spreadsheet model", "economy sim", or a system spec from game-systems-designer with `TBD` placeholders. Produces an economy spreadsheet, balance pass plan, sim outputs, and per-system balance tables. Stops at the numbers — does not change system rules or pricing. For systems design see game-systems-designer; for store catalog see iap-manager.

Triggers on edits to analytics integration files, or mentions of "PostHog", "analytics", "feature flag", "event tracking", "capture", "identify", "A/B test", or "experiment".

jpoindexter Skill Tufte Data ForensicsUse when an analysis, dataset, spreadsheet, model, benchmark, or research claim must be audited before it is trusted or acted on — deciding what to demand from a data supplier, tracing a number back to its measurement, screening for randomization, image, binning, or batch-effect failures, scoring a study's credibility, separating a forensic audit from data cleaning, or naming who paid for the answer.
-
lukaskellerstein Bundle XLSXThis skill should be activated when the user asks to create, edit, read, or analyze Excel spreadsheet files (.xlsx, .xlsm, .csv, .tsv). Triggers for: building financial models, creating data tables, formatting spreadsheets, adding formulas, cleaning tabular data, converting between tabular formats.

alihusains Skill Data Analytics SQL ReviewReviews analytical SQL for correctness and cost: the join fan-out and row-loss traps, filters that silently change join semantics, window and grain errors, null and timezone handling, then scan volume, partition pruning, and predicate placement. Use when a query is about to feed a report or model, when results look wrong or duplicated, when a query is expensive or slow, or when reviewing someone else's analytical SQL. Trigger on 'review this query', 'why are my rows duplicated', 'this query is expensive', 'check my SQL', 'the join is wrong', 'why is this so slow'. Not for verifying a finished report's outputs against an independent source — that is data-analytics-report-qa; not for deciding what the metric should mean, which is data-analytics-metric-definition.

alihusains Skill Data Analytics Metric DefinitionTurns a metric name into a binding definition contract: the population, the qualifying event, the time grain, the timezone, the deduplication rule, restatement policy, and a single named owner. Use when two teams report different numbers for the same metric, when a new KPI is being introduced, when a dashboard figure cannot be reconciled with a report, or when a definition needs reviewing before it goes into a board pack. Trigger on 'what counts as an active user', 'our numbers do not match', 'define this metric', 'metric definition', 'why is the dashboard different from the report', 'source of truth for X'. Not for checking whether a specific report is correct before it ships — that is data-analytics-report-qa; not for reviewing the query that implements the definition, which is data-analytics-sql-review.

alihusains Skill Cross Functional Spreadsheet BuildBuilds a spreadsheet somebody else will maintain: inputs, calculations and outputs on separate sheets, no constants buried inside formulas, a documented assumptions block, a checks sheet that fails loudly, and a written refresh procedure. Use when producing a model, tracker, budget, forecast, pricing sheet, reconciliation or allocation workbook that will be reopened next month by someone who did not build it. Trigger on 'build me a spreadsheet', 'make this into an Excel model', 'turn this into a workbook', 'build a forecast/budget/pricing model', 'can you produce an xlsx', 'this sheet keeps breaking'. Not for checking numbers already produced by a report or dashboard (use data-analytics-report-qa), not for agreeing what a metric means before it is modelled (use data-analytics-metric-definition), and not for writing the narrative that accompanies a variance (use finance-budget-vs-actual-commentary).

omicverse Bundle Omicverse Microbiome PhylogenyBuild an ASV-level phylogenetic tree (MAFFT alignment + FastTree GTR+Γ), attach it to a 16S AnnData, and run phylogenetically-aware diversity (Faith PD, weighted / unweighted UniFrac). Use when adding tree-aware metrics on top of the basic 16S amplicon AnnData, or when the cohort needs UniFrac-driven beta-diversity instead of Bray-Curtis.
-
omicverse Bundle Omicverse Microbiome Da ComparisonRun all three differential-abundance methods (Wilcoxon, pyDESeq2, ANCOM-BC) on the same microbiome AnnData, compare their hit sets via 3-way Venn / overlap counts, and decide which to trust on a given cohort. Use when the user wants to benchmark DA methods on a 16S study, when picking between methods on a small or zero-inflated cohort, or when reporting consensus features that survive multiple tests.
-
omicverse Bundle Omicverse Microbiome Meta AnalysisCombine multiple per-study microbiome AnnDatas into a single cross-cohort table and run inverse-variance / random-effects meta-analysis on differential abundance. Use when you have 16S studies from multiple cohorts that need joint analysis, when you need a combined log2 fold-change with Cochran's I² heterogeneity, or when you want to find features whose effect replicates across cohorts (vs. cohort-specific signals).
-
omicverse Bundle Omicverse Bulk Metabol PreprocessingRun the canonical metabolomics preprocessing chain on an AnnData peak table — impute, normalize, transform — and apply LC-MS-specific drift / batch / sample QC corrections (drift_correct, SERRF, ComBat, sample_qc). Use when converting `t_metabol_01_intro` or `t_metabol_06_batch_correction` into a reusable skill, when a user has a MetaboAnalyst CSV / LC-MS peak table to clean before differential or multivariate analysis, or when choosing among PQN/TIC/median sample-normalization, log/Pareto feature-transformation, and qrilc/knn/half_min/zero imputation strategies.
