hyperliquid-reader

hyperliquid-reader is a skill for Claude Code from himself65/finance-skills. It costs 157 tokens per session (2,702 once invoked), scanned A, original, MIT.

A read-only tool for viewing public Hyperliquid market data. Hyperliquid is an online exchange for perpetual futures and spot markets, where perpetuals are contracts without a fixed expiry date.

In plain words
What is it for?
Use it to inspect markets, prices, funding rates, open interest, trading volume, order books, and price candles.
Why use it?
It provides market information without needing a wallet or allowing trades, so analysis cannot directly change an account or move funds.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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

hyperliquid-reader 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 2d 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 — 160 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Hyperliquid Reader (Read-Only)

If your host has not already executed the shell probes below (for example, in Codex), run the commands inside the ! wrappers with its shell tool before choosing a setup path. Use the actual output; if shell access is unavailable, report that limitation.

Reads Hyperliquid — the on-chain perps/spot DEX — for market data via opencli and the hyperliquid plugin in this repo's opencli-plugins/hyperliquid tree (a separate plugin from opencli's built-in adapters, installed via opencli's monorepo subpath syntax).

This skill is read-only and market-data only. It reads Hyperliquid's fully public info API for analysis: market tables, funding, order book, and candles. It does NOT read individual accounts, place/modify/cancel orders, or move funds. There is no trading path in the plugin — order placement requires wallet-signed actions on a separate endpoint this adapter never calls.

How it works: every command issues a single POST https://api.hyperliquid.xyz/info with a { "type": "..." } body and normalizes the response. No API key, no wallet, no login, no running app — the info API is public.


Step 1: Ensure opencli + Plugin Are Installed and Ready

Current environment status:

!`(command -v opencli && opencli hyperliquid markets --coin BTC -f json 2>&1 | head -3 && echo "READY" || echo "SETUP_NEEDED") 2>/dev/null || echo "NOT_INSTALLED"`

If the status above shows READY, skip to Step 2. Otherwise:

NOT_INSTALLED — Install opencli

npm install -g @jackwener/opencli

Requires Node.js >= 24 — the hyperliquid plugin declares engines.node >= 24.

SETUP_NEEDED — Install the Hyperliquid plugin

The Hyperliquid adapter is not built into opencli — it's a separate plugin:

opencli plugin install github:himself65/finance-skills/hyperliquid

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.
