What it does
Low Power Embedded is an agent skill from mohitmishra786/low-level-dev-skills. Low-power embedded skill for sleep modes and energy optimization. Use when configuring MCU sleep/stop/standby, peripheral clock gating, wake-up sources, or measuring firmware current draw. Activates on queries about WFI, STOP mode, STM32 PWR, nRF sleep, wake-up EXTI, or reducing embedded power consumption.
Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development, covering Embedded systems. The repository describes itself as: A curated suite of AI agent skills for systems and low-level programming with C/C++, Rust, and Zig toolchains, covering compilers, debuggers, profilers, build systems…. The licence is MIT.
When your agent uses it
- Configuring MCU sleep/stop/standby
- Peripheral clock gating
- Wake-up sources
- Measuring firmware current draw
Example prompts
- “/low-power-embedded”
Workflow steps
8 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit bdc5847. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are c).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Low Power Embedded loads about 1k tokens when it runs. Until then it costs about 82 tokens; SKILL.md has 328 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- low-power-embedded
- description
- Low-power embedded skill for sleep modes and energy optimization. Use when configuring MCU sleep/stop/standby, peripheral clock gating, wake-up sources, or measuring firmware current draw. Activates on queries about WFI, STOP mode, STM32 PWR, nRF sleep, wake-up EXTI, or reducing embedded power consumption.
Low-Power Embedded
Purpose
Guide agents through MCU low-power modes: sleep vs deep sleep (stop/standby), peripheral and bus clock gating, wake-up source configuration, and practical current measurement — with Cortex-M WFI/WFE and vendor PWR examples (STM32-focused patterns apply broadly).
When to Use
- Battery-powered firmware missing power budget
- Wake-up latency vs consumption tradeoffs
- Debugging "device won't wake" or "current still mA in sleep"
- Before shipping RTOS idle hook or bare-metal main loop sleep
- Cross-linking with
skills/baremetal/interrupts-and-exceptions-baremetal
Workflow
1. Power mode hierarchy (STM32-style)
| Mode | CPU | Peripherals | RAM | Wake source | Relative current |
|---|---|---|---|---|---|
| Run | on | on | on | — | highest |
| Sleep | off | on | on | any IRQ | medium |
| Stop | off | most off | on | EXTI, RTC, UART | low |
| Standby | off | off | lost* | WKUP pins, RTC | lowest |
* Standby clears most SRAM; use backup domain or external EEPROM for state.
2. Enter Sleep (WFI)
/* Cortex-M — sleep until interrupt */
__disable_irq();
/* configure wake source (e.g. EXTI, RTC alarm) */
__enable_irq();
__WFI(); /* or __WFE() for event-based wake */Ensure pending interrupts are cleared before WFI or wake may be immediate.
3. STM32 Stop mode pattern
#include "stm32f4xx.h"
void enter_stop_mode(void)
{
/* Gate clocks you do not need */
RCC->AHB1ENR &= ~RCC_AHB1ENR_GPIOAEN; /* example — only if safe */
PWR->CR |= PWR_CR_CWUF; /* clear wake flags */
PWR->CR |= PWR_CR_PDDS; /* deep sleep = Stop */
SCB->SCR |= SCB_SCR_SLEEPDEEP_Msk;
__WFI();
/* After wake: re-enable HSE/PLL — clocks lost in Stop on many parts */
SystemInit();
}After Stop, re-init clocks and peripherals that lost their registers.
4. Clock gating checklist
Before sleep
├── Disable unused peripheral clocks (RCC xENR)
├── Disable ADC/DAC continuous modes
├── Stop DMA channels
├── Enter peripheral low-power (UART mute, SPI off)
└── Configure lowest viable regulator scale (Voltage Scale 2/3)5. Wake-up sources
| Source | Config |
|---|---|
| EXTI GPIO | SYSCFG + EXTI IMR, edge trigger |
| RTC alarm | RTC WUT/WAKEUP |
| UART | Start bit detection (some MCUs) |
| IWDG | Not a wake source — resets device |
6. Measurement tips
- Use ammeter in series with VDDA/VDD; short sampling window for uA
- DWT cycle counter for wake latency benchmarking
- Compare run vs sleep current with same clock tree documented
7. RTOS note
FreeRTOS configUSE_TICKLESS_IDLE maps to WFI/Stop — coordinate with skills/embedded/freertos.
8. Agent usage
/low-power-embedded Configure STM32 Stop mode with EXTI0 wake and PLL restoreCommon Problems
| Symptom | Cause | Fix |
|---|---|---|
| Still mA in "sleep" | Debug interface active (SWD) | Disconnect debugger; disable DBGMCU |
| Immediate wake from WFI | Pending NVIC IRQ | Clear flags before WFI |
| Lost state after wake | Entered Standby not Stop | Use Stop if RAM must persist |
| UART dead after wake | Clock tree not restored | Call SystemInit() path |
| Higher than datasheet uA | Floating GPIO | Set unused pins analog or pull |
