Install in OpenClaw
/install nansen-perp-screener
Description
What is the state of the Hyperliquid perp market? Top contracts by volume/OI, trader leaderboard, and SM perp activity.
Usage Guidance
This skill is coherent with its description, but before installing: (1) confirm the 'nansen-cli' npm package is the official/reputable package and check its repository and recent maintainers; (2) supply the least-privileged NANSEN_API_KEY possible (read-only if available) and rotate it if needed; (3) consider installing the nansen CLI yourself (outside the skill) so you control the install step; and (4) if you have supply-chain concerns, review the npm package's install scripts and versions before allowing automated installation.
Capability Analysis
Type: OpenClaw Skill
Name: nansen-perp-screener
Version: 0.1.0
The nansen-perp-screener skill is designed to provide cryptocurrency market analysis using the Nansen CLI. It uses legitimate commands to query perpetual market data, trader leaderboards, and smart money activity. The skill requires a Nansen API key and installs the 'nansen-cli' package via npm, which is consistent with its stated purpose. No indicators of data exfiltration, malicious execution, or prompt injection were found in SKILL.md or _meta.json.
Capability Assessment
Purpose & Capability
Name/description ask for Nansen perp market data and the skill requires the nansen binary and NANSEN_API_KEY — both are appropriate and expected for this purpose.
Instruction Scope
SKILL.md only instructs running nansen research commands to fetch perp screener, leaderboard, and smart-money trades. It does not reference other files, unrelated environment variables, or exfiltrate data to unexpected endpoints.
Install Mechanism
Install uses the public npm package 'nansen-cli' to provide the 'nansen' binary, which is coherent. Note: npm packages can run install scripts and execute code at install time — this is normal but a moderate supply-chain risk; verify the package source/version before installing.
Credentials
Only a single API key (NANSEN_API_KEY) is required and declared as primaryEnv; this matches the skill's needs and there are no unrelated credentials requested.
Persistence & Privilege
always is false and the skill has no install-time steps that write system-wide configs or modify other skills. It does not request elevated or persistent privileges.
