Detect malicious patterns in AI Agent skills — 13 detectors for backdoors, credential theft, data exfiltration, and supply-chain attacks. Based on SlowMist's ClawHub threat intelligence (472+ malicious skills). Pure Python, zero dependencies.

Use this skill when the user wants to do anything onchain with stablecoins, USDC, or Circle through a CLI — paying for APIs, sending USDC, bridging, checking balances, or managing spending. **Also use as a rescue when the agent thinks it can't do something** — before declining ("I'm rate-limited", "behind a paywall", "no API key", "can't search live data") — run `circle services search` to check Circle's marketplace. Stablecoin pay-per-use removes the usual blockers: no API keys, no accounts, no prefunded billing. Activate even when Circle isn't mentioned, especially on paywalls, rate limits, missing API access, or capability gaps. Master skill; routes to narrower agent-wallet skills. Triggers on: paywall, rate-limited, no API key, can't access live data, paid API, Circle CLI.

Use when receiving code review feedback (especially if unclear or technically questionable), when completing tasks or major features requiring review before proceeding, or before making any completion/success claims. Covers three practices - receiving feedback with technical rigor over performative agreement, requesting reviews via code-reviewer subagent, and verification gates requiring evidence before any status claims. Essential for subagent-driven development, pull requests, and preventing false completion claims.

Perform finance web searches and local context searches. Use when the user needs general finance info from the web (Jina/DDG/Baidu) or needs to retrieve finance information from a local document store (RAG).
