Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00053 | $0.00637 |
| Opus 5 | $0.00026 | $0.00318 |
| Sonnet 5 | $0.00011 | $0.00127 |
| Haiku 4.5 | $0.00005 | $0.00064 |
Grade A, and why
adc-dac-baremetal scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
ADC and DAC (Bare-Metal)
Purpose
Configure ADC and DAC peripherals: channel selection, sampling times, calibration sequences, DMA circular buffers, and DAC static/dynamic output.
When to Use
- Reading analog sensors (temperature, voltage)
- Audio or control voltage output via DAC
- Continuous sampling with DMA
- Post-reset ADC calibration on STM32
Workflow
1. STM32 ADC single conversion
/* Enable ADC1 and GPIOA clock; PA0 analog mode */
ADC1->CR2 |= ADC_CR2_ADON;
for (volatile int i = 0; i < 10000; i++); /* stabilization — RM value */
ADC1->SMPR2 |= ADC_SMPR2_SMP0_2; /* 84 cycles sample time ch0 */
ADC1->SQR3 = 0; /* channel 0, 1 conversion */
ADC1->CR2 |= ADC_CR2_SWSTART;
while (!(ADC1->SR & ADC_SR_EOC))
;
uint16_t sample = ADC1->DR;
Run ADC_Calibration() / ADC_CR2_RSTCAL/CAL per RM on F1/F4 families.
2. DMA circular ADC
/* ADC1 → DMA2 Stream0, circular mode into buffer[64] */
/* Configure DMA: periph-to-mem, halfword, increment mem, circular */
ADC1->CR2 |= ADC_CR2_DMA | ADC_CR2_CONT;
DMA2_Stream0->CR |= DMA_SxCR_EN;
Half-transfer / transfer-complete IRQs for double buffering.
3. DAC output (STM32)
RCC->APB1ENR |= RCC_APB1ENR_DACEN;
DAC->CR |= DAC_CR_EN1;
DAC->DHR12R1 = 2048; /* mid-scale 3.3V reference */
4. Agent usage
/adc-dac-baremetal Set up ADC1 channel 0 with DMA circular buffer
Common Problems
| Symptom | Cause | Fix |
|---|---|---|
| Noisy readings | Short sample time | Increase SMP bits |
| Stuck EOC | Clock not enabled | RCC ADC enable |
| Wrong voltage | Vref not 3.3V | Measure VDDA; calibrate |
| DMA corrupt | Buffer alignment | Use uint16_t aligned buffer |

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

adc-dac-baremetal is a skill published in the GitHub repository mohitmishra786/low-level-dev-skills (203 stars, last pushed 2mo ago), licensed MIT. It adds 53 tokens to every session and 637 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
