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.

First: check profile

Read .nutmeg.user.md. If it doesn't exist, tell the user to run /nutmeg:init first. 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 the specific system. Key conversions:

• Opta (0-100) to StatsBomb (120x80): x * 1.2, y * 0.8
• Wyscout to Opta: x stays, y = 100 - y (invert Y)
• Any to kloppy normalised: use kloppy's .transform() in Python
