nutmeg-brainstorm
Brainstorm
Help the user explore and choose football data visualisation approaches through research-backed ideation and collaborative refinement.
Accuracy
Read and follow docs/accuracy-guardrail.md before answering any question about provider-specific facts (IDs, endpoints, schemas, coordinates, rate limits). Always use search_docs — never guess from training data.
First: check profile
Read .nutmeg.user.md. If it doesn't exist, tell the user to run /nutmeg first. Use their profile for:
- Programming language (Python/R/JS)
- Visualisation libraries they use (mplsoccer, matplotlib, ggplot2, d3, Observable)
- Experience level (adapt complexity of suggestions)
- Available data sources (what providers they have access to)
References (load as needed)
This skill has two reference documents. Load them when relevant — don't read both upfront for every question.
More from withqwerty/nutmeg
nutmeg-analyse
Explore, interpret, and draw conclusions from football data. Use when the user wants to analyse match events, compare teams or players, understand tactical patterns, build visualisations, or needs guidance on what questions to ask of their data. Adapts to the user's experience level.
52nutmeg-learn
Learn about football analytics concepts and explore provider documentation. Use when the user asks what a metric means (xG, PPDA, expected threat, xT), wants learning resources, papers, or courses, is new to football analytics, or wants a learning path. Also use when the user asks about data provider documentation — qualifier IDs, coordinate systems, event types, API schemas, field mappings, identity surfaces, provider ID schemes — or wants to compare providers, look something up in the docs, or find out what data a provider offers.
44nutmeg
Football data analytics — the single entry point. Use whenever the user mentions football data, xG, expected goals, match analysis, player stats, scouting, match reports, shot maps, passing networks, Premier League data, Champions League stats, scraping FBref/Understat/Transfermarkt, building football charts, or anything football analytics related. Routes to specialised sub-skills automatically. Also handles first-time setup and profile management.
43nutmeg-compute
Calculate derived football metrics and models. Use when the user wants to compute xG, xGOT, PPDA, passing networks, expected threat, possession value, pressing intensity, or any derived football statistic from raw data.
43nutmeg-heal
Fix broken data scrapers and pipelines. Use when data acquisition fails, a scraper breaks, an API returns errors, or data format has changed. Also handles submitting upstream issues or PRs when the problem is in a dependency like soccerdata or kloppy.
42nutmeg-wrangle
Transform, filter, reshape, join, and manipulate football data. Use when the user needs to clean data, merge datasets, convert between formats, handle missing values, work with large datasets, or do any data manipulation task on football data.
