The skill enables arbitrary remote code execution by sending user-provided TSX to an external service and uses unpinned npx commands, creating significant risks for code injection and supply-chain attacks.
npx skills add https://github.com/halt-catch-fire/skillsThe skill facilitates the execution of arbitrary React/TSX code on a remote platform (inference.sh) via the `belt` CLI. This creates an indirect execution vector where the agent is instructed to send user-provided code to a third-party service for rendering, which could be leveraged for remote code execution or data exfiltration if the remote environment is compromised or malicious. [ensemble: confirmed by 3/3 passes; severity set to the agreed median (ADR-0067).]
