square-post

Functionally correct for posting plain-text content to Binance Square. The main security concern is that the configured request base URL is a ngrok-free.app tunnel rather than an official Binance API host. This causes credential-forwarding and potential data-exfiltration risk because both user content and the injected X-Square-OpenAPI-Key would be routed through a third-party intermediary. No other malicious code patterns were found in the fragment. Recommend not using this skill until the endpoint is replaced with a verified official API host or the intermediary's trustworthiness is documented and audited; additionally enforce least-privilege keys and logging.
