3 findings — 3 medium severity. This skill can be installed but you should review these findings before use.
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
Third-party content exposure detected (high risk: 1.00). The skill fetches and parses arbitrary public RSS feeds (checkRSS: fetch(source.config.feedUrl)), pulls Twitter posts via a Nitter RSS endpoint (checkTwitter: fetch(`${nitter}/${username}/rss`)), and accepts webhook payloads (SKILL.md webhook POST), and that untrusted, user-generated content is analyzed in processSignal to decide and execute automated trades, so third‑party content can directly influence agent actions.
The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.
Potentially malicious external URL detected (high risk: 0.90). At runtime this skill fetches external feeds (e.g., the hard-coded Nitter instance https://nitter.privacydev.net and arbitrary RSS feed URLs passed to /signal add rss) and uses the fetched content to decide and execute trades, so remote content directly controls agent actions.
The skill is specifically designed for direct financial operations, giving the agent the ability to move money or execute financial transactions — such as payment processing, cryptocurrency operations, banking integrations, or market order execution.
Direct money access detected (high risk: 1.00). The skill explicitly automates crypto trades: it monitors RSS/Twitter/webhook signals "to trigger automatic trades", has commands to configure trade amount and slippage, filter rules that map signals to buy/sell, auto-detect token mint addresses, and lists support for crypto DEX routing (Raydium, Jupiter, Pump.fun). These are specific crypto trading/execution capabilities (swaps/orders), not generic tooling, so it grants direct financial execution authority.
