Explain football analytics concepts and provider documentation: what a metric means (xG, PPDA, xT), learning paths and resources, and provider details such as qualifier IDs, coordinate systems, event types, schemas, ID schemes, coverage, or comparing providers.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Learn
Teach football analytics concepts, recommend resources, provide a learning path, and answer questions about data provider documentation — all adapted to the user's level.
## Accuracy
Read and follow `${CLAUDE_PLUGIN_ROOT}/docs/accuracy-guardrail.md` before answering any question about provider-specific facts (IDs, endpoints, schemas, coordinates, rate limits). Always use `search_docs` — never guess from training data.
When the user asks what a metric means, read its football-docs metric card with `get_metric` (`list_metrics` shows the cards) and explain that variants exist, naming their IDs; use `search_docs` for metrics without a card.
## First: check profile
Read `.nutmeg.user.md`. If it doesn't exist, continue with sensible defaults (Python and pandas, intermediate level) and suggest running `/nutmeg` setup at the end.
## Glossary of core concepts
The glossary is in `${CLAUDE_PLUGIN_ROOT}/docs/glossary.md`: chance quality (xG, npxG, xGOT, xA, xT), possession and
pressing (PPDA, high press, counterpressure, build-up, possession value), passing, shooting and defensive terms,

How to install
mdr add withqwerty/nutmeg/nutmeg-learn@sha256:33e47e1d5ba2c7daThe line at the top of this page pins the label git:20261010.da11349, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
