A comprehensive knowledge base of professional skills for building with Zephyr RTOS.

This repository contains a curated collection of "skills"—modular packages of knowledge, code patterns, and best practices—designed to assist AI agents and human developers in building high-quality embedded systems with Zephyr.

The master index for all skills is located within the zephyr-index skill:

👉 Master Skill Catalog

• zephyr-foundations: Embedded C patterns & safe coding.
• build-system: West, Sysbuild, Kconfig, & CMake.
• devicetree: Syntax, bindings, & hardware description.
• native-sim: Simulation & host-based testing.
• board-bringup: Custom board definitions (HWMv2).

• kernel-services: Threads, Work Queues, Zbus, & Logging.
• hardware-io: GPIO, I2C, SPI, DMA, & Sensors.
• power-performance: PM states, optimized builds, & RAM tuning.

• connectivity-ble: Bluetooth Low Energy (GAP/GATT).
• connectivity-ip: IPv6, CoAP, MQTT, & LwM2M.
• connectivity-usb-can: USB device classes & CAN bus.

• security-updates: MCUboot, Image Signing, & DFU.
• iot-protocols: OpenThread, Matter, & Golioth.
• multicore: SMP, OpenAMP, & IPC.
• industrial: Modbus RTU/TCP & CANopen.
• specialized: Audio, LVGL GUI, & Reliability.

• Discovery: Start by reading skills/zephyr-index/SKILL.md to understand the available capabilities.
• Implementation: When a user requests a task (e.g., "Add BLE support"), locate the corresponding skill (connectivity-ble) and strictly follow the patterns in its references/ directory.
• Verification: Use the code examples provided in references/ as ground truth for syntax and API usage.

• Learning: Treat each skill as a focused tutorial. The references/ folder in each skill contains "cheat sheets" for specific topics.
• Best Practices: The content emphasizes professional, production-ready patterns over simple "Hello World" examples.

This repository can be added as a plugin marketplace in Claude Code.

1. Add the Marketplace:

   claude plugin marketplace add beriberikix/zephyr-agent-skills

   (Or claude plugin marketplace add . if working in a local clone)

2. Install All Skills:

   claude plugin install zephyr-skills@zephyr-agent-skills

3. Install Specific Skills:

   claude plugin install connectivity-ble@zephyr-agent-skills

Each skill is a self-contained directory with the following structure:

• SKILL.md: Entry point and quick start.
• references/*.md: Detailed technical guides and code snippets.
• scripts/ & assets/: Helper files (where applicable).

To add a new skill, use the skill-creator utility or follow the structure of existing skills.
