Expert code review for embedded/firmware projects with dual-model cross-review (Claude + Codex via ACP). Detects memory safety, interrupt hazards, RTOS pitfalls, hardware interface bugs, and C/C++ anti-patterns. Trigger when user asks to review embedded/firmware/MCU code changes, diffs, or PRs. Examples: 'review firmware-pro2 的改动', 'review the NFC changes', '/embedded-review ~/path/to/repo', '/embedded-review ~/path/to/repo HEAD~5..HEAD', '/embedded-review <github-pr-url>'. Target environments: bare-metal MCU (STM32, nRF, ESP32, RP2040), RTOS (FreeRTOS/Zephyr/ThreadX), Linux embedded, mixed C/C++ firmware.

Operate SEGGER J-Link for embedded bring-up and hardware-in-the-loop loops: detect probes, flash firmware, start/stop GDB server, resolve RTT address from map files, capture RTT logs, and drive gdb in batch mode for breakpoints/step/variable inspection. Use when a user asks to burn/download firmware, run real-board debug sessions, set breakpoints, inspect memory/registers, or automate compile→flash→RTT verification on STM32/MCU projects.

Dump the current STM32 LCD framebuffer via J-Link and convert it to PNG for visual comparison with Figma. Auto-detects the front buffer by reading LTDC L1CFBAR so the screenshot matches what the LCD is actually showing (works correctly with double-buffered LVGL direct mode). Supports RGB888 and RGB565 — pick the one matching the target's LTDC configuration (PRO2 currently uses RGB565). Use when user asks to export, snapshot, dump, or capture what is currently displayed on device screen.

Apply the ClawHQ / Claude.ai-inspired design system to any web project. Use when: restyling an existing dashboard or web page to match ClawHQ's visual style, unifying multiple web tools under a consistent look, or building a new web UI from scratch in this style. Triggers on phrases like 'apply Claude style', 'make it look like Claude.ai', 'unify to Claude.ai style', 'apply our design system', 'restyle this dashboard', 'same style as clawhq'.

Publish a local service (Node.js, Python, any HTTP server) to the public internet on macOS using Cloudflare Tunnel + launchd LaunchAgent. Use when setting up a new local web service that should be accessible via a public domain, adding a Cloudflare Tunnel to an existing local server, managing (status/restart/logs) a deployed local-publish service, or tearing down a published service. Triggers on phrases like 'publish local service', 'expose local port', 'set up CF tunnel', 'make local server public', 'add cloudflare tunnel', 'deploy local dashboard'.
