reap-07-firmware-and-embedded SKILL.md skillA
reap-07-firmware-and-embedded from joasasantos/rea-prompts is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

REA prompt pack: Firmware & embedded (3 ready-to-paste prompts). Use when doing reverse-engineering investigation of firmware & embedded with REA (rea.tools) via an AI coding agent.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# REAP — 7. Firmware & embedded Part of REAP (REA Investigation Prompts). Replace everything in <angle brackets>; keep each request focused on one feature. Demand file/function/address evidence and separate facts from hypotheses. ### Firmware image triage ```text Use REA to analyze <firmware image / bin / img>. Identify the container format, extract partitions/filesystems (JFFS2, SquashFS, UBI, cramfs...), map each region to architecture and load address, locate the kernel and rootfs, and list boot entries, init scripts and services. Show offsets, entropy observations and the evidence for every claim. Start with static analysis; do not flash or run anything. ``` ### MCU / IoT binary analysis ```text Use REA on <firmware blob> for a <ARM Cortex-M / MIPS / AVR / ESP32> target. Find the vector table and reset handler, reconstruct the memory map from literal pools and peripheral base addresses, identify the RTOS (FreeRTOS, Zephyr...) from symbol/string fingerprints, and map the main task loop and peripheral drivers (UART, SPI, I2C, radio stack) with function addresses. ``` ### Embedded protocol & update mechanism ```text …

How to install
mdr add joasasantos/rea-prompts/reap-07-firmware-and-embedded@sha256:cc9e5a15099ad7faThe line at the top of this page pins the label git:20261025.9bd45a8, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
