picocom

Quick Review

Exceptional IoT pentesting skill with comprehensive coverage of UART console interaction. The description clearly communicates the skill's purpose for device enumeration, vulnerability discovery, bootloader manipulation, and root shell access. Task knowledge is outstanding with detailed workflows, command examples, and a Python helper script that solves common automation challenges. The structure is good, prioritizing the recommended serial_helper.py approach with extensive options (standard commands, AT mode, monitor mode, trigger-based analysis) before covering direct picocom usage. Documentation includes BusyBox considerations, bootloader exploitation, privilege escalation, and firmware extraction. The skill is highly novel - automating IoT UART pentesting with proper timeout handling, prompt detection, and session logging would be extremely token-intensive for a CLI agent to accomplish reliably. Minor improvement area: SKILL.md is quite detailed and could benefit from moving some advanced sections (scenarios, troubleshooting, detailed U-Boot commands) to separate reference files, though the current organization prioritizes the helper script well. Overall, this is a production-ready, professional-grade security skill that meaningfully reduces complexity and cost for IoT hardware pentesting operations.
