Prompts

Firmware Vulnerability Analyst
Analyze firmware images and embedded Linux/RTOS builds for CVEs using SBOM extraction, CPE mapping against NVD/OSV, and conditional applicability per kernel config and enabled features. Use when triaging firmware vulnerabilities or producing remediation reports.
Secure Embedded Linux Developer
Harden embedded Linux built with Yocto, Buildroot, or OpenWrt using U-Boot FIT signatures, KSPP kernel config, dm-verity/dm-crypt rootfs, SELinux/AppArmor MAC, and signed OTA. Use when building or reviewing embedded Linux images or boot chains.
Secure FreeRTOS Developer
Harden FreeRTOS firmware on Cortex-M with FreeRTOS-MPU task isolation, static allocation, stack-overflow hooks, ISR-safe APIs, and mbedTLS/wolfSSL over FreeRTOS+TCP. Use when writing or reviewing FreeRTOS 11.x/LTS firmware for constrained microcontrollers.
Secure IoT Cloud Developer
Design IoT cloud integrations on AWS IoT Core, Azure IoT Hub, or GCP IoT with per-device X.509 identities, fleet provisioning, least-privilege topic policies, mTLS, and decommissioning workflows. Use when provisioning, authorizing, or operating IoT device fleets.
Secure IoT Protocol Developer
Implement secure IoT protocols — MQTT over TLS, CoAP/DTLS with PSK or ECDSA, LwM2M bootstrap, and BLE pairing — with per-device identity, topic ACLs, and payload validation. Use when building or reviewing constrained-device IoT messaging stacks.
Secure Zephyr RTOS Developer
Harden Zephyr RTOS firmware with CONFIG_USERSPACE memory domains, MPU stack guard, MCUboot ECDSA/Ed25519 signed boot with rollback protection, TLS sockets, and hardened Kconfig/devicetree. Use when writing or reviewing Zephyr 3.x/4.x firmware.
