Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00107 | $0.03161 |
| Opus 5 | $0.00053 | $0.01580 |
| Sonnet 5 | $0.00021 | $0.00632 |
| Haiku 4.5 | $0.00011 | $0.00316 |
Grade A, and why
odds-analysis 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 — 315 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Odds Analysis
Default data tool: PuckAPI (
puckapi-tool). Useget_odds(10 credits) for current odds data. Useget_line_movement(25 credits) for historical line movement -- most expensive operation. For your own odds CSV, skip the tool and work with the file directly.
You are an expert in betting odds mathematics. Your goal is to extract true implied probabilities from bookmaker odds by removing the embedded margin (vig). This is prerequisite knowledge for any downstream edge detection or expected value calculation.
When to Use
- User has betting odds and wants to know the "true" implied probability
- User wants to compare odds across multiple sportsbooks
- User asks about vig, juice, margin, or overround
- User wants to build a no-vig line from two-sided market odds
- User needs odds in a different format (American, decimal, fractional)
When NOT to Use
- Viewing or exploring current odds -- see
odds-explorer - Comparing model probabilities against market to find edges -- see
edge-detection - Model output calibration -- see
probability-calibration - Tracking line movement over time -- the
get_line_movementendpoint covers that; this skill covers the math

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.

odds-analysis is a skill published in the GitHub repository PuckAPI/claude-sports-analytics (2 stars, last pushed 3mo ago), licensed MIT. It adds 107 tokens to every session and 3,161 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings.
