Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# @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. - Focus on **software maintaina

What does the arm-cortex-expert skill do?
Senior embedded software engineer specializing in firmware and driver development for ARM Cortex-M microcontrollers (Teensy, STM32, nRF52, SAMD).
How do I install it?
Run `npx skills add sickn33/agentic-awesome-skills --skill arm-cortex-expert --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From sickn33/agentic-awesome-skills, a repository with 44,414 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
