playoff-simulation

playoff-simulation is a skill for Claude Code from PuckAPI/claude-sports-analytics. It costs 93 tokens per session (2,832 once invoked), scanned A, original, MIT.

A hockey simulator that uses Monte Carlo methods, meaning it models many possible season outcomes, to estimate NHL playoff, division, championship, and draft-position probabilities.

In plain words
What is it for?
Use it to simulate the rest of an NHL season, estimate a team's playoff or Stanley Cup chances, compare division odds, or simulate a playoff bracket.
Why use it?
It turns team ratings and the remaining schedule into probability estimates instead of relying on a single prediction.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

playoff-simulation scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 268 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Playoff Simulation

Default data tool: PuckAPI (puckapi-tool) for current standings and remaining schedule. Use get_standings (2 credits) and get_games (5 credits) for remaining schedule. Elo ratings as input: use elo-engineering to build, or bring your own rating system. For your own data (CSV of standings + ratings), skip the tool and work with the file directly.

You are an expert in Monte Carlo season and playoff simulation. Your goal is to take any team rating system, simulate thousands of futures, and produce probability distributions for every meaningful outcome: playoff berths, division titles, championship odds, and draft position. PuckCast runs 10,000 iterations nightly; the methodology here produces the same class of output.

When to Use

  • User asks what the playoff odds are for a specific team
  • User wants to know championship probabilities across the league
  • User asks who is likely to win the division
  • User wants to simulate the rest of the season
  • User asks for bracket simulation after the playoff field is set
  • User wants to see how ratings translate to probability distributions

When NOT to Use

  • Single game win probability -- see model-building or game-preview
  • Team evaluation without simulation context -- see team-analysis
  • Player-level analysis or valuation -- see player-scouting
  • Running Elo ratings from scratch -- see elo-engineering first, then bring ratings here

Commands Available

Command What It Does Credits
get_standings Current standings, points, record 2
get_games Remaining schedule for all teams 5
get_team_stats Goal data for Pythagorean ratings 5

Commands That Do NOT Exist

Not Available Use Instead
simulate_season Implement Monte Carlo loop in Python
get_playoff_odds Compute from simulation output
get_championship_probability Output of simulation, not a direct endpoint

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
