Tools & prompts
good-sport is a research assistant, not a picks service — it shows its edges and its misses.
You don't call these tools directly. You ask your assistant in plain language; it picks the right tool, runs it against the models, and explains the answer. Here's the surface, with prompts to copy.
Tonight's offered prop lines ranked by the model's edge over the market, across MLB, NHL, and tennis.
The same offered lines with a concentration flag — a heads-up when an edge leans on a single book.
A single-prop deep dive — the model's number, the market's, and the reasoning around the gap.
Optimal parlay candidates built to avoid stacking correlated legs.
Kalshi contracts priced against the model's probabilities.
Where the market is moving — steam and sharp-money line movement. A market signal, explicitly not a model edge.
Reconciled ROI and calibration — how often the model is right, grouped by confidence, against what actually happened.
Closing-line value — did the model's picks beat the closing line, the textbook sign an edge is real.
Fantasy football draft copilot — best available by value over replacement for your league's exact shape, with tier cliffs, roster needs, and the market's own uncertainty on every player. Not picks; roster research.
Feed-health checks — freshness, completeness, and accuracy across the slate and stats feeds, so you know the inputs are clean.
