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

opportunity 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 3d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (index.ts), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Opportunity Finder - Complete API Reference

Discover and execute cross-platform arbitrage opportunities across Polymarket, Kalshi, Betfair, Smarkets, Manifold, Metaculus, PredictIt, and Drift.

Based on arXiv:2508.03474 which found $40M+ in realized arbitrage on Polymarket.

Opportunity Types

Type Description Example
Internal YES + NO < $1 on same platform Buy both for guaranteed profit
Cross-Platform Same market priced differently Buy low on A, sell high on B
Combinatorial Logical violations (P(A) > P(B) when A implies B) Trump > Republican
Edge Market vs external model (538, polls) Market 45%, model 52%

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
