esp32-chips

A reference guide to the capabilities of several Espressif ESP32 system-on-chip families used in M5Stack boards. It covers hardware features such as peripherals, sleep modes, memory, USB, wireless radios, and processor extensions.

In plain words
What is it for?
Use it when writing ESP-IDF code for classic ESP32, ESP32-S3, ESP32-C6, or ESP32-P4 hardware, especially for memory, power, wireless, USB, or processor features.
Why use it?
It prevents developers from having to rediscover chip-specific limits and settings for every M5Stack board. It also keeps shared chip information in one place.

Grade A, and why

esp32-chips 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 yesterday.

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 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.

esp32-chips is a plugin published in the GitHub repository iot-forge/m5stack-skills (2 stars, last pushed 7d ago), licensed MIT. Its token cost is not measured: this kind of file is read by the harness, not the model. 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 2026-08-31.
