This trading-analysis skill is not clearly malicious, but it automatically installs and updates external code and stores an optional API key in local files, which users should review before installing.
Install only if you are comfortable with the skill cloning and updating external GitHub repositories, installing Python packages, using local MT5/TradingView data access, and keeping a TradingView key in ~/.tlc/.env. Prefer entering secrets directly into the local file rather than chat, review the upstream repositories and setup script first, and remove the ~/.tlc configuration if you no longer want the persistent state.
