LOW

Why flagged The package downloads a prebuilt toolchain from Espressif's official domain (dl.espressif.com), which is the legitimate vendor for ESP8266 tools; despite the static analyzer flagging the host as non-standard, this is a normal and trusted source for the software, and the download is verified via sha256sum.
