Data & Analytics

owid Skill

Search Our World In Data's published charts by keyword to find the chart you need, across topics like population, energy and electricity, CO2 and climate, poverty and GDP, health and causes of death, education, democracy, violence and war. Use this whenever someone wants to find, browse, link or embed an OWID chart and does not already have its URL, or asks what OWID publishes on a topic. Returns each chart's title, subtitle and URL, plus which visualisations it supports so you can build a ?tab= link. Not for: fetching the data behind a URL you already have (use fetch-chart-data); Python or pandas work, indicator and column metadata, or searching the full catalog of indicators and tables beyond published charts (use owid-catalog); combining OWID data with your own (use joining-data).

yaniv-golan Bundle

Deterministic library-first regression — fit a CSV against the calculator-primitive witness library (unary, affine `a·w(x)+b` with constant snapping, depth-2 composite `w(v(x))`, binary `w(x,y)`) and emit a machine-checkable JSON verdict ranked by max |residual| and R². Use when you need a reproducible, audit-able answer to "which elementary law generated this data?" — the JSON output is downstream-consumable (no LLM in the loop), exit codes encode the verdict, complex-plane evaluation via cmath catches branch-cut hazards. Snaps to π, e, 1/ln(10), Catalan G, ζ(3), Khinchin K, log₂(e), e^π, γ, etc. Optional `--noise-sigma σ` for measured data; reports SE(a)/SE(b).

tale-project Bundle

Use this skill whenever you change the shape of the 0.5 backend database — a new table, a new column, an index, a constraint, a backfill, or a data reshape. It owns the authoring contract (one numbered .sql file under services/platform/backend/db/migrations/, applied at boot in filename order inside one advisory lock), the forward-only doctrine (every migration must be safe to apply to a live deployment mid-roll, because the previous image is still serving while the new one migrates), the org-config file lane (config trees are NOT database rows — they move through the scaffolder), and the proof duty (the real-Postgres integration check). Load it before adding anything under backend/db/migrations/.

thapaliyabikendra Bundle

skillmedev Skill

Turns SQL query results into a decision-ready business narrative - headline finding, drivers, recommendation - plus the right chart choice for the data shape. Use when someone asks "what does this data actually mean", "summarize these query results for the exec team", "what chart should I use for this", or pastes a result set and wants the so-what for a non-technical audience. Do NOT use to diagnose or speed up the query itself - use sql-query-optimizer instead; do NOT use to build a full multi-part narrative presentation around an analysis - use data-story instead; do NOT use for open-ended exploration of an unfamiliar dataset - use eda-playbook instead.

cap-go Bundle

Guides the agent through migrating SQLite and SQL-style Capacitor plugins to @capgo/capacitor-fast-sql. Use when replacing bridge-based SQL plugins, adding encryption, preserving transactions, or moving key-value storage onto Fast SQL.

Analyzes an A/B experiment to a defensible verdict - sample-size and minimum-detectable-effect math, two-proportion significance testing with confidence intervals, and checks for the traps that fake a win (peeking, sample ratio mismatch, multiple comparisons). Use when someone asks "is this test significant", "did variant B win", "how long should I run this experiment", "what sample size do I need", or shows experiment results and asks whether to ship. Do NOT use for logging and organizing ML training runs - use experiment-tracking instead; for causal questions without a randomized experiment use causal-inference; for general funnel or metric investigation use funnel-analysis or product-analytics.
