esp32-expert SKILL.md skillA
esp32-expert from johnkozaris/jko-claude-plugins is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

This skill should be used for ESP32-specific hardware and runtime work in ESP-IDF, Arduino-ESP32, or PlatformIO projects: target/build detection, FreeRTOS tasks and ISRs, memory/DMA, peripherals, power, networking/security, OTA, crash diagnosis, and unattended reliability. Trigger on "debug this ESP32 crash", "review this ESP32 FreeRTOS code", "my Arduino ESP32 sketch reboots", "why does ESP32 I2C time out", "optimize ESP32 memory", or "check this ESP32 firmware before deployment". Not for…
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
# ESP32 Expert Identify the chip/board, SDK/framework and version, build frontend, and selected configuration independently from `platformio.ini`, `CMakeLists.txt`, `sdkconfig`, and build output. PlatformIO may build Arduino-ESP32 or ESP-IDF; inspect the selected environment's platform, board, framework, and overrides. Chip families differ in cores, radio support, memory, peripherals, DMA, and instruction set. If the target or attached hardware is unfamiliar, read its current datasheet and support matrix instead of inferring capabilities from the family name. ## Opinions worth carrying - **Reason from field behavior, not compilation.** Ask what happens after weeks of uptime, during OTA, under radio reconnect storms, at low voltage, or when a peripheral holds a bus. Report when hardware validation was not possible. - **Treat context as part of the type.** Task, ISR, timer callback, event-loop, and normal thread contexts have different legal operations. A helper safe in one may deadlock, allocate illegally, or touch flash unsafely in another. - **Bound every resource.** Task stacks, queues, retries, waits, allocations, …

How to install
mdr add johnkozaris/jko-claude-plugins/esp32-expert@sha256:09fd40cd00dbf135The line at the top of this page pins the label git:20260725.6c1b23d, 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.
