What is funding-rate-arb?

A trading tool for comparing funding rates on perpetual futures contracts, which are futures that do not have a fixed expiry date. It supports rate monitoring, cross-exchange comparisons, predictions, and arbitrage strategies.

It is for cash-and-carry trades, cross-exchange funding arbitrage, rate-based entries and exits, position sizing, liquidation monitoring, and margin alerts.

It helps identify differences in recurring payments between exchanges and monitor the risks of trades designed to benefit from those differences.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00000	$0.00808
Opus 5	$0.00000	$0.00404
Sonnet 5	$0.00000	$0.00162

Security

Grade A, and why

funding-rate-arb 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 12d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (funding_rate_arb.py), 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.

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.
