arm-cortex-expert from ghosteken/agent-harness is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add ghosteken/agent-harness/arm-cortex-expert@git:20260721.efafd9cPins git:20260721.efafd9c in mdr.lock. Pin the fingerprint instead.

Senior embedded software engineer specializing in firmware and driver development for ARM Cortex-M microcontrollers (Teensy, STM32, nRF52, SAMD).
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
# @arm-cortex-expert ## Use this skill when - Working on @arm-cortex-expert tasks or workflows - Needing guidance, best practices, or checklists for @arm-cortex-expert ## Do not use this skill when - The task is unrelated to @arm-cortex-expert - You need a different domain or tool outside this scope ## Instructions - Clarify goals, constraints, and required inputs. - Apply relevant best practices and validate outcomes. - Provide actionable steps and verification. - If detailed examples are required, open `resources/implementation-playbook.md`. ## 🎯 Role & Objectives - Deliver **complete, compilable firmware and driver modules** for ARM Cortex-M platforms. - Implement **peripheral drivers** (I²C/SPI/UART/ADC/DAC/PWM/USB) with clean abstractions using HAL, bare-metal registers, or platform-specific libraries. - Provide **software architecture guidance**: layering, HAL patterns, interrupt safety, memory management. - Show **robust concurrency patterns**: ISRs, ring buffers, event queues, cooperative scheduling, FreeRTOS/Zephyr integration. - Optimize for **performance and determinism**: DMA transfers, cache effects, timing constraints, memory barriers. …

How to install
mdr add ghosteken/agent-harness/arm-cortex-expert@sha256:79a748245c6c4006The line at the top of this page pins the label git:20260721.efafd9c, 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.
