Use at the start of any sports modeling project.\nlicense: MIT\nmetadata:\n  version: \"0.12.0\"\n---\n\n# Sports Modeling Doctrine\n\n## Outcome\n\nWrite a modeling charter before acquiring data or fitting models. The charter is\na user-owned source of truth for the question, target, timing, evaluation, and\nshape of done.\n\nBefore code, lock the scientific contract:\n\n- what question is being answered;\n- what one row represents;\n- what is knowable at decision time;\n- what baseline counts as evidence of value;\n- how success will be measured out of time;\n- what result causes acceptance, revision, or stopping.\n\nIf these fields are not named, do not fit a model.\n\n## When to use this skill\n\nUse it when starting or reframing a sports analysis, deciding what “good” means,\nreviewing whether a result is evaluable, or preventing exploratory work from\nquietly becoming a predictive claim.\n\nAfter the charter, use only the relevant specialist skills: a public-source\nloader for acquisition, `eda-sports` for data understanding, `feature-rules` for\ntime-safe predictors, `baseline-models` for reference models, and the relevant\nstatistical, predictive, rating, simulation, or validation skill.\n\n## Question types\n\n| Type | Core question | Required evidence | Common overreach |\n|---|---|---|---|\n| Descriptive | What happened? | coverage, denominators, uncertainty | treating the sample as every era/population |\n| Explanatory | What is associated? | design, effects, uncertainty, confounding limits | causal language |\n| Predictive | What will happen after time `T`? | time-safe inputs and ordered holdout | explaining coefficients as causes |\n| Causal | What changes under an intervention? | identification strategy and assumptions | using prediction alone |\n| Ranking | Who is strongest as of `T`? | future utility, schedule context, rank stability | treating point ranks as certain |\n| Simulation | What distribution follows assumptions? | calibrated inputs and sensitivity | reporting simulated precision as observed fact |\n\nDo not mix explanatory and predictive success. A stable association need not\nimprove forecasts, and a useful predictor need not identify a causal mechanism.\n\n## Charter workflow\n\n1. Write the question in one sentence.\n2. Name sport, competition, population, era, and exclusions.\n3. Define grain: game, team-game, player-game, possession, play, pitch, or other.\n4. Classify the analysis type using the table above.\n5. For predictive, ranking, or prospective simulation work, define decision\n   time `T` and forecast horizon precisely.\n6. Define target or estimand, units, label rules, and treatment of ties or missing outcomes.\n7. Record base rate, null expectation, or incumbent process.\n8. Name at least one naive and one strong simple baseline.\n9. Lock the primary metric and its direction before fitting.\n10. Choose validation that respects event, season, and availability order.\n11. Define data requirements, minimum coverage, and provenance standards.\n12. Write acceptance, failure, revision, and stop conditions.\n13. Record out-of-scope decisions and unsupported uses.\n\n## Grain and decision-time contract\n\nFor each proposed field, be able to answer:\n\n```text\nrow grain: <what one row represents>\nentity/event key: <natural key>\ndecision time T: <timestamp or event boundary>\nforecast horizon: <what future interval is predicted>\nfeature available by T: <yes/no and source timestamp>\ntarget observed after T: <yes/no>\npaired/dependent rows: <shared games, players, series, seasons>\n```\n\nSports data routinely contain doubled team-game rows, postgame summaries,\nrevised injury reports, end-of-season aggregates, and ratings updated after the\nevent. Column names do not prove availability. Define an as-of rule.\n\n## Baseline ladder\n\n| Level | Example | Purpose |\n|---|---|---|\n| Null | constant training prevalence or historical mean | proves value beyond no differentiation |\n| Structural | venue indicator, prior rank, or league average by context | captures obvious domain structure |\n| Strong simple | shifted form, simple rating, or regularized linear/logistic model | tests whether complexity earns its cost |\n| Incumbent | current operational forecast or public reference | measures practical replacement value |\n\nLock baseline definitions, training windows, and missing-data behavior before\ncandidate tuning. All models must be scored on identical held-out rows.\n\n## Metric defaults\n\n| Target | Primary candidates | Baseline | Important secondary evidence |\n|---|---|---|---|\n| Binary outcome | log-loss, Brier | prevalence, venue/simple rating | calibration and fold spread |\n| Margin/continuous | MAE, RMSE | historical mean or simple rating | residual distribution and interval coverage |\n| Count | Poisson deviance, MAE | historical mean count | dispersion and zero behavior |\n| Time to event | proper survival score/concordance | simple survival estimate | calibration by horizon |\n| Ranking | future-result correlation or utility | prior rank/rating | rank stability and uncertainty |\n| Simulation | distributional score or coverage | simple empirical distribution | sensitivity to assumptions |\n\nAccuracy is rarely sufficient for probability work. Match the metric to the\ndecision, define its direction, and compute it only on genuinely held-out data.\n\n## Validation defaults\n\nOrdered sports events usually require expanding-window or rolling-origin\nvalidation. A default season walk-forward design trains on seasons before `s`\nand evaluates on season `s`. When a sport lacks clean seasons, split by event\ntime with explicit gaps or embargoes where labels/features overlap.\n\nRandom row shuffles are not the default because they can mix future roster,\nteam-strength, schedule, and feature information into training. Group shared\ncontests together, and account for repeated teams or players when estimating\nuncertainty.\n\n## Acceptance and stopping rules\n\nA predictive candidate is normally worth keeping only if it:\n\n- beats locked baselines on the mean primary metric;\n- improves in a meaningful majority of eligible folds or has a justified pooled result;\n- passes time-safety and leakage checks;\n- avoids catastrophic calibration if probabilities are quoted;\n- remains useful under relevant era, team, player, or event slices;\n- justifies its complexity and maintenance burden.\n\nFor explanatory work, require stable effect direction, honest uncertainty, and\nbounded claims. For simulation, require input calibration and sensitivity.\n\nRead [`references/good_enough.md`](references/good_enough.md) when setting the\nacceptance rule. Stop when the rule is met, when a failure condition invalidates\nthe work, or when further complexity does not earn material held-out value.\n\n## Charter schema\n\n```text\nquestion\nsport_and_competition\npopulation_and_exclusions\ngrain_and_natural_key\nanalysis_type\ndecision_time_and_horizon\ntarget_or_estimand\nbase_rate_or_null\nnaive_and_strong_baselines\nprimary_metric_and_direction\nsecondary_metrics\nvalidation_design\ndata_requirements_and_provenance\nuncertainty_plan\nacceptance_rule\nfailure_and_stop_conditions\nout_of_scope_and_prohibited_uses\nrequired_artifacts\n```\n\n## Worked charters\n\n### Pre-game team-win probability\n\n```text\nQuestion: Do venue and shifted form improve P(team wins)?\nSport/population: NFL completed regular-season games, 2018-2024\nGrain: team-game; two paired rows per contest\nDecision time: scheduled kickoff\nTarget: won; ties reported separately\nBaselines: constant training prevalence; venue-only logistic\nPrimary metric: held-out log-loss, lower is better\nValidation: season walk-forward; contest rows remain together\nAcceptance: beat both baselines in mean and at least five of seven folds\nFailure: any feature not provably available before kickoff\nOut of scope: causal claims and wagering profitability\n```\n\n### Player next-game count\n\n```text\nQuestion: Predict a starter's strikeouts in the next start.\nGrain: player-game\nDecision time: first pitch\nTarget: strikeouts in that start\nBaselines: trailing shifted mean; opponent strikeout-allowed mean\nPrimary metric: MAE\nValidation: date walk-forward with player histories truncated at T\nCold start: separate rule and reporting slice\n```\n\nRead [`references/charter_examples.md`](references/charter_examples.md) for\nadditional compact NFL, NBA, and MLB patterns.\n\n## Non-negotiables and integrity rules\n\n1. Time order matters; random event shuffles need explicit justification.\n2. Features must be legal at `T` for prospective claims.\n3. Baselines are defined before candidate models.\n4. The primary metric is locked before inspecting test folds.\n5. Grain changes require explicit aggregation and key validation.\n6. Candidate and baseline use identical held-out populations.\n7. Failures and non-improvement are recorded as valid results.\n8. Strong claims require a leakage audit and honest uncertainty.\n9. Public data does not eliminate provenance, licensing, or snapshot duties.\n10. Scope does not expand silently after favorable results appear.\n11. Use the simplest model that meets the charter.\n12. Record decisions and artifacts outside ephemeral chat.\n\n## Anti-patterns\n\n- choosing an algorithm before defining the decision;\n- feature soup without an availability timestamp;\n- calling one hot season “generalization”;\n- changing the primary metric after seeing held-out results;\n- treating each team-game row as an independent game;\n- copying the same assumptions across sports with different schedules or rules;\n- continuing to tune after the test window becomes familiar;\n- declaring victory because a complex model beats the null but not a strong simple baseline;\n- producing probabilities without a calibration plan.\n\n## Helper\n\n```bash\npython <path-to-sports-modeling-doctrine>/scripts/print_charter_template.py \\\n  --out data/modeling_charter.md\n```\n\nFill the user-owned template before data acquisition or fitting. The helper\ndoes not choose the question, baseline, or acceptance rule.\n\n## Operating and handoff rules\n\n- Use only the skills relevant to the charter; every skill must stand alone.\n- Pass explicit user-owned artifacts between acquisition, analysis, and reporting steps.\n- Keep the charter current when a justified scope decision changes.\n- Re-charter rather than quietly changing target, grain, or decision time.\n- Report a blocker when timing, grain, provenance, or evaluation cannot be established.\n\nFor optional downstream routing, read\n[`references/skill_path.md`](references/skill_path.md). It is a decision aid,\nnot a requirement to invoke every listed skill.\n\n## Output contract\n\nReturn or save the completed charter with question, type, sport/population,\ngrain/key, decision time, target, baselines, primary metric, validation,\nuncertainty, acceptance/failure rules, out-of-scope uses, and required artifacts.\nDo not return an algorithm recommendation without this contract.\n\n## Resources\n\n- [`references/charter_examples.md`](references/charter_examples.md) — read for\n  sport- and target-specific charter examples.\n- [`references/good_enough.md`](references/good_enough.md) — read when defining\n  acceptance, failure, and stopping rules.\n- [`references/skill_path.md`](references/skill_path.md) — read when choosing\n  optional specialist handoffs after the charter.\n- `scripts/print_charter_template.py` — portable charter writer.\n","tagline":"Define a sports analysis or prediction question, grain, decision time, baselines, primary metrics, validation, and acceptance criteria before choosing algorithms.
