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.

SkillSpector: 2 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00000 | $0.05344 |
| Opus 5 | $0.00000 | $0.02672 |
| Sonnet 5 | $0.00000 | $0.01069 |
| Haiku 4.5 | $0.00000 | $0.00534 |
Grade A, and why
lgt8f328p-minievb 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 8d 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.
How it starts
The opening of the file, as written. The whole thing — 259 lines — stays where its author put it; the contents beside it link to each section on GitHub.
LGT8F328P-LQFP32 MiniEVB ("LGTBF32BP")
A board that looks exactly like an Arduino Nano, takes the same sketches, and is not one. The
LGT8F328P is a Logic Green LGT8XM core that executes the AVR instruction set inside a chip
with a different clock system, a 12-bit ADC, a DAC, four timers, no real EEPROM and no
crystal. board.build.mcu is literally atmega328p, so everything compiles and most things
silently behave differently. Almost every failure on this board is a Nano assumption that
was not true.
Read the reference files rather than reasoning from ATmega328P knowledge.
reference/board-hardware.md— the complete board reference: the LQFP32 pin map with the four bonded pads, Arduino pin numbering past D19, timer/PWM map, PMX0/1/2 alternate routing, the HDR high-current table, power tree, clock tree, memory map and the EEPROM emulation, plus a development guide (§8 toolchain and measured build sizes, §9 the clock-prescaler trap, §10 peripheral cookbook, §11 core gotchas, §12 flashing and SWD recovery, §13 symptom → cause → fix table).reference/recipes.md— copy-paste code:platformio.ini,board.h, blink, the 12-bit ADC, measuring the real VCC, the DAC on D4, Timer3 PWM on D1/D2, 80 mA drive, emulated EEPROM, moving the UART to D5/D6, sleep, and disabling SWD.template/— a project that builds clean, in two variants, plus a scaffold script. Seetemplate/README.md.
Confirm the board first
The silkscreen LGTBF32BP is Logic Green's stylisation of LGT8F328P, not a different part.
What actually has to be decided is the package, because it picks the core variant:
| Package | Board | PlatformIO board |
build.variant |
|---|---|---|---|
| LQFP32 | Nano-style 30-pin MiniEVB, "purple nano", WAVGAT — this skill | LGT8F328P |
lgt8fx8p |
| LQFP48 | MiniEVB 48-pin breakout | lgt8f328p-LQFP48 |
lgt8fx8p48 |
| SSOP20 | "green pseudo Pro Mini" | LGT8F328P-SSOP20 |

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.

lgt8f328p-minievb is a skill published in the GitHub repository alexex1993/mcu-skills (17 stars, last pushed 2d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 5,344 tokens. 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 2026-09-04.
