> /path/to/logs/scraper.log 2>&1 ``` Never inline API keys directly in crontab entries. ``` ### Technical Analysis The setup instructions direct the user to install a cron entry that survives the original Skill run, user logout, and system reboot. It executes the scraper once per minute without further interactive authorization. Recurring execution is relevant to the declared real-time monitoring function, and the entry does not use `sudo` or attempt privilege escalation. Nevertheless, installing a cross-session scheduled task grants the Skill persistent network and filesystem activity. This exceeds the privileges required for a one-time trade synchronization operation. The command also sources the user's entire `~/.profile`. Consequently, every command subsequently placed in that file will be executed by cron once per minute, even if it is unrelated to the scraper. This unnecessarily expands the execution surface. ### Attack Path 1. The user follows the setup instructions and edits their user crontab. 2. The cron entry remains registered after the Skill's interactive setup has ended. 3. Every minute, cron sources the complete `~/.profile`. 4. Cron then runs the scraper with the user's permissions. 5. The process repeatedly performs outbound API requests and writes to the configured database, state, alert, and log paths. 6. If `~/.profile` is later modified with unsafe or compromised commands, those commands are also executed every minute in the cron context. ### Impact Assessment No admi ...[truncated 624 chars]- Remediation
