Wrangle

Help the user manipulate football data effectively. This skill is about the mechanics of working with data, adapted to the user's language and tools.

Accuracy

Read and follow ${CLAUDE_PLUGIN_ROOT}/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, continue with sensible defaults (Python and pandas, intermediate level) and suggest running /nutmeg setup at the end. Use their profile for language preference and stack.

Core operations

Coordinate transforms

Football data coordinates vary by provider. Always verify and convert before combining data.

Use search_docs(query="coordinate system", provider="[provider]") to look up each provider's origin, ranges and y-axis direction. Do not write a conversion formula from memory: providers differ in which touchline y=0 sits on, so a formula that only rescales can mirror the pitch.
