Yield Shark

🦈 YieldShark - DeFi stablecoin yield monitor with real-time APY tracking across 50+ platforms

Security Scan

The skill appears to be what it claims — a Node-based DeFi stablecoin yield monitor that queries public APIs and contains marketing/docs — with no obvious disproportionate credential or install demands, though a few minor inconsistencies and privacy/operational notes deserve attention before you run it.

Purpose & Capability

Name/description match what the repository contains: Node scripts for monitoring, comparing, calculating, alerting, and reporting yields from public DeFi data sources (DeFiLlama/Coingecko). Required binaries (node, npm) and a node-fetch dependency are appropriate for this purpose.

Instruction Scope

SKILL.md and scripts instruct running local Node scripts (e.g., node scripts/monitor.mjs) and reference DeFiLlama and other public APIs — this fits the stated purpose. Several promotional files include CLI publish instructions and paths (e.g., /root/.openclaw/...) and wallet addresses; those are documentation/promotion artifacts and not required at runtime. Some scripts (alert.mjs) describe notification modes like telegram/webhook/email but only simulate behavior; confirm whether monitor.mjs actually performs network requests before running.

Install Mechanism

There is no formal install spec in the registry metadata (no automated download/install), but package.json and multiple scripts are included. That is coherent for a skill you run locally, but the metadata's 'instruction-only' note (if present elsewhere) is slightly misleading given the presence of code files. No remote binary downloads or obscure URLs are used in the manifest.

Credentials

The skill declares no required environment variables or credentials. Some documentation (publish guides) shows using a CLAWHUB_TOKEN for publishing to ClawHub — that is an optional publisher-action and not required for normal monitoring. No requests for unrelated cloud credentials or secret environment variables are present in runtime scripts.

Persistence & Privilege

The skill does not request always:true and does not declare any system config paths or privileged persistent hooks. It runs as local Node scripts; nothing in the package indicates it will force-enable itself or modify other skills.

Assessment

This package is generally coherent with its stated purpose, but before running or publishing it you should: 1) Review scripts/monitor.mjs and other .mjs files to see exactly which external endpoints they call and whether any hard-coded endpoints or webhooks exist; 2) Run the code in a safe environment (container or VM) and inspect outgoing network requests (to confirm only DeFiLlama/Coingecko and expected APIs are contacted); 3) Be cautious with the publish instructions — they ask you to obtain/enter a CLAWHUB token (this is normal for publishing, but never paste tokens into unknown places or share them publicly); 4) Double-check the sponsor wallet addresses if you plan to send funds; and 5) If you expect automated notifications (telegram/email/webhook), verify whether the code actually implements them and what credentials would be required — provide those only to code you trust. If you want, I can scan specific script files (monitor.mjs, report.mjs) for network calls and any suspicious patterns.
