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. A

Choose how and where to store football data. Use when the user asks about database choices, file formats, cloud storage, data pipelines, or how to organise their football data project. Also covers publishing and sharing outputs (Streamlit, Observable, GitHub Pages).

Fetch, scrape, or download football data from any source. Also handles API key setup and credential management. Use when the user wants to get data from StatsBomb, Opta, FBref, Understat, SportMonks, Wyscout, Kaggle, or any football data source. Also use when they ask about API keys, authentication, setting up access to a provider, or what data is available free vs paid.

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.

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, ident

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.

Brainstorm football data visualisations and chart designs. Use when the user wants ideas for how to visualise football data, needs inspiration for chart types, wants to explore design approaches for match reports, player profiles, team dashboards, or any football analytics graphic. Searches the web for popular approaches and real-world examples before proposing options.

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.

Review football data code and visualisations for correctness. Use after building a chart, data pipeline, or analysis. Dispatches specialised reviewers for data correctness, chart conventions, visual inspection, and interactive edge cases.

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.

Use this skill when the user is mid-build and drifting, scope is creeping, or focus is lost. Trigger on "ship focus", "scope check", "refocus", "what should I cut", "am I scope creeping", "this is getting bigger than expected", "I'm losing focus", "I keep finding things to improve", "should I stop and ship what I have", or "new requirements came in". Also trigger when the user expresses frustratio

Use this skill when the user wants to set up, configure, or initialize the ship plugin, create or update their ship profile, change their review mode, update their product brief, or edit .claude/ship.local.md. Trigger on "ship init", "set up ship", "configure ship", "create my profile", "update my profile", "change review mode to brutal/kind", or when any other ship skill detects that .claude/ship

Use this skill when the user wants a weekly check-in, retrospective, or recalibration of how they're building. Trigger on "ship debrief", "debrief", "weekly check-in", "how am I doing", "where did my time go", "ship retro", "debrief with dhh", "recalibrate my profile", "update my priorities", or when the user wants to reflect on their recent work and adjust direction. Also trigger when another shi

Use this skill when the user is about to start building something and would benefit from hard questions before coding. Trigger on "ship think", "gut check", "sanity check", "should I build this", "before I start", "does this make sense", "is this worth building", "is this overkill", or "thoughts on this approach". Also trigger when the user describes a feature, migration, rewrite, or architectural
