domain-embedded

Q: How do I install domain-embedded?

Run npx skills add https://github.com/actionbook/rust-skills --skill domain-embedded in your project. The skills CLI detects the agents you use and copies the skill into the right folder. For Claude Code you can also place the skill folder at ~/.claude/skills/domain-embedded/ (personal) or .claude/skills/domain-embedded/ (project).

Install

Works with every agent the skills CLI supports.

npx skills add https://github.com/actionbook/rust-skills --skill domain-embedded

01
Install
Run the command in your project. The CLI asks which agents to install for.
02
Describe the task
Ask your agent for something this skill covers. It loads domain-embedded automatically when relevant.
03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.

SKILL.md

The instructions your agent reads when the skill is triggered.

Embedded Domain

Layer 3: Domain Constraints

Domain Constraints → Design Implications

Domain Rule	Design Constraint	Rust Implication
No heap	Stack allocation	heapless, no Box/Vec
No std	Core only	#![no_std]
Real-time	Predictable timing	No dynamic alloc
Resource limited	Minimal memory	Static buffers
Hardware safety	Safe peripheral access	HAL + ownership
Interrupt safe	No blocking in ISR	Atomic, critical sections

Critical Constraints

No Dynamic Allocation

RULE: Cannot use heap (no allocator)
WHY: Deterministic memory, no OOM
RUST: heapless::Vec<T, N>, arrays

Interrupt Safety

RULE: Shared state must be interrupt-safe
WHY: ISR can preempt at any time
RUST: Mutex<RefCell<T>> + critical section

Hardware Ownership

RULE: Peripherals must have clear ownership
WHY: Prevent conflicting access
RUST: HAL takes ownership, singletons

Trace Down ↓

From constraints to design (Layer 2):

"Need no_std compatible data structures"
    ↓ m02-resource: heapless collections
    ↓ Static sizing: heapless::Vec<T, N>

"Need interrupt-safe state"
    ↓ m03-mutability: Mutex<RefCell<Option<T>>>
    ↓ m07-concurrency: Critical sections

"Need peripheral ownership"
    ↓ m01-ownership: Singleton pattern
    ↓ m12-lifecycle: RAII for hardware

Layer Stack

Layer	Examples	Purpose
PAC	stm32f4, esp32c3	Register access
HAL	stm32f4xx-hal	Hardware abstraction
Framework	RTIC, Embassy	Concurrency
Traits	embedded-hal	Portable drivers

Framework Comparison

Framework	Style	Best For
RTIC	Priority-based	Interrupt-driven apps
Embassy	Async	Complex state machines
Bare metal	Manual	Simple apps

Key Crates

Purpose	Crate
Runtime (ARM)	cortex-m-rt
Panic handler	panic-halt, panic-probe
Collections	heapless
HAL traits	embedded-hal
Logging	defmt
Flash/debug	probe-run

Design Patterns

Pattern	Purpose	Implementation
no_std setup	Bare metal	`#![no_std]` + `#![no_main]`
Entry point	Startup	`#[entry]` or embassy
Static state	ISR access	`Mutex<RefCell<Option<T>>>`
Fixed buffers	No heap	`heapless::Vec<T, N>`

Code Pattern: Static Peripheral

#![no_std]
#![no_main]

use cortex_m::interrupt::{self, Mutex};
use core::cell::RefCell;

static LED: Mutex<RefCell<Option<Led>>> = Mutex::new(RefCell::new(None));

#[entry]
fn main() -> ! {
    let dp = pac::Peripherals::take().unwrap();
    let led = Led::new(dp.GPIOA);

    interrupt::free(|cs| {
        LED.borrow(cs).replace(Some(led));
    });

    loop {
        interrupt::free(|cs| {
            if let Some(led) = LED.borrow(cs).borrow_mut().as_mut() {
                led.toggle();
            }
        });
    }
}

Common Mistakes

Mistake	Domain Violation	Fix
Using Vec	Heap allocation	heapless::Vec
No critical section	Race with ISR	Mutex + interrupt::free
Blocking in ISR	Missed interrupts	Defer to main loop
Unsafe peripheral	Hardware conflict	HAL ownership

Trace to Layer 1

Constraint	Layer 2 Pattern	Layer 1 Implementation
No heap	Static collections	heapless::Vec<T, N>
ISR safety	Critical sections	Mutex<RefCell<T>>
Hardware ownership	Singleton	take().unwrap()
no_std	Core-only	#![no_std], #![no_main]

FAQ

What does the domain-embedded skill do?

How do I install domain-embedded?

Run npx skills add https://github.com/actionbook/rust-skills --skill domain-embedded in your project. The skills CLI detects the agents you use and copies the skill into the right folder. For Claude Code you can also place the skill folder at ~/.claude/skills/domain-embedded/ (personal) or .claude/skills/domain-embedded/ (project).

Which AI agents can use domain-embedded?

It provides a quick reference for agent types, tool definitions, orchestration patterns, callbacks, state management, the graph Workflow API, and reference recipes to study. Do NOT use for scaffolding (use google-agents-cli-scaffold) or deployment (use google-agents-cli-deploy).

embedded-captions

heygen-com/hyperframes

Add captions or subtitles to an existing single-subject talking-head video without editing the footage. Use for plain verbatim captions, cinematic captions embedded behind the subject, VFX captions, “炸/特效/酷炫字幕,” or a named identity from the 35-style catalog. Route by visual identity, not by backend engine. The quiet anchor rail is the default; embed every word only when the user explicitly wants a fully cinematic treatment. The workflow runs locally end to end, including transcription and subject matting; split multi-shot footage before applying it.
