# Embedded Linux Login Debug ## Overview Use this skill to choose a safe login path for an embedded Linux device before debugging. The agent should identify the available access method, collect only the required connection details, and start with read-only checks after login. ## When To Use Use this skill when: - The user wants to log in to an embedded Linux device, development board, router, gateway, camera, or appliance. - The user mentions SSH, serial console, UART, ADB, Telnet, local console, recovery console, or vendor web debug access. - The task requires checking runtime state on a target device before changing files, services, partitions, networking, or firmware. Do not use this skill when: - The target is a normal cloud server or desktop Linux machine with a known access path. - The user only needs static source-code analysis and no device access. - The request is to flash firmware, erase storage, modify bootloader settings, or change partitions without a separate safety plan. ## Login Method Decision Ask which access methods are available. If the user is unsure, suggest this order: 1. SSH over network, if the device has an IP address and SSH server. 2. Serial UART console, if network access is unavailable or boot logs are needed. 3. ADB, if the target is Android-based or exposes Android Debug Bridge. 4. Telnet, only for trusted lab networks or legacy devices. 5. Local console with display and keyboard, if physically accessible. 6. Vendor web or recovery co...
