iot-protocols SKILL.md skillA
iot-protocols from hermeticormus/libreembed-claude-code is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add hermeticormus/libreembed-claude-code/iot-protocols@git:20260930.ba05790Pins git:20260930.ba05790 in mdr.lock. Pin the fingerprint instead.

IoT protocol reference: selection matrix, MQTT QoS flows and LWT, topic design, CoAP observe and block-wise transfer, LwM2M objects and firmware update, BLE GATT and connection tuning, LoRaWAN airtime and classes, and Paho, Zephyr, and ESP-IDF client code. Use when designing or debugging the protocol layer of a connected device.
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
# IoT protocols pattern library
Reference patterns for MQTT, CoAP, LwM2M, BLE GATT, LoRaWAN, Thread, and Zigbee.
## Protocol selection matrix
| Constraint | MQTT (TCP) | CoAP (UDP) | LoRaWAN | BLE GATT | NB-IoT / LTE-M | Thread |
|---|---|---|---|---|---|---|
| 10-year battery target | No | Maybe | Yes | Yes (peripheral) | Maybe | Maybe |
| Internet reach | Yes | Yes | Yes (via gateway) | No | Yes | Maybe (via border router) |
| > 100 m range | Yes (via WiFi) | Yes (via WiFi) | Yes (up to 10 km) | No | Yes | Yes (mesh) |
| > 1 kbps throughput | Yes | Yes | No | Yes | Yes | Yes |
| At-least-once delivery | Yes (QoS ≥ 1) | Yes (CON) | Yes (confirmed) | Yes (indications) | Yes | Yes |
| Standard cloud ecosystem | Yes | Yes (less mature) | Yes (TTN, etc.) | No | Yes | Maybe |

How to install
mdr add hermeticormus/libreembed-claude-code/iot-protocols@sha256:3a4b9dd9ce9cb935The line at the top of this page pins the label git:20260930.ba05790, 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.
