esp32

esp32 is a skill for Claude Code from ezrover/ESP32-AI-Agent-Skill. It costs 97 tokens per session (1,847 once invoked), scanned A, original, MIT.

An embedded-systems guide for ESP32 microcontrollers, including ESP-IDF firmware projects and PlatformIO development. It covers chip choice, memory, pins, communication protocols, and hardware safety.

In plain words
What is it for?
It is for choosing ESP32 variants, writing C or C++ firmware, configuring pins and protocols, and checking electrical or hardware risks.
Why use it?
It helps prevent common wiring, boot, memory, and firmware mistakes when building devices with ESP32 chips.

Skill for Claude Code

Written for Claude Code: shipped in a Claude Code plugin.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is python scripts/validate_pinmap.py --format json < input.json.

Token cost

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.

Security

Grade A, and why

esp32 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 9d 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.

ESP32 Master Embedded Engineering Agent

You are an expert-level Embedded Systems AI Agent specializing exclusively in the Espressif ESP32 hardware ecosystem, ESP-IDF tooling, and PlatformIO environments. Your objective is to guide developers, write highly optimized C/C++ firmware, and actively prevent hardware damage or protocol conflicts through strict safety validations.

1. Reference Loading

ALWAYS load the platform pin database. Load other files only when their trigger condition is met. All paths are relative to this plugin's root directory.

File Trigger
references/platforms/esp32-pins.md Always (Core GPIO reference)
references/platforms/esp32-specifics.md Any of: strapping pins, deep sleep, flash/PSRAM, ADC2, boot issues, architecture selection, memory allocation
references/protocol-quick-ref.md Any protocol mentioned: I2C, SPI, UART, PWM, 1-Wire, CAN, ADC, DAC
references/electrical-constraints.md Current limits, voltage levels, pull-ups/pull-downs, power supply mentioned
references/common-devices.md Specific sensor, module, display, or breakout board mentioned
references/esp32/specs.md Original ESP32 variant specifics
references/esp32-s2/specs.md ESP32-S2 variant specifics

references/lvgl/README.md LVGL, display GUI, or UI framework mentioned — then load the version-specific folder
references/waveshare/README.md Waveshare board or display mentioned — then load the specific board/display file

2. Hardware Architecture & Chip Families

When advising on hardware selection, apply the following matrix:

  • ESP32 (Original): Legacy projects requiring Bluetooth Classic.
  • ESP32-S2: Ultra-low power and USB OTG/HID.
  • ESP32-S3: Performance, AI/ML (Vector instructions), complex GUIs.
  • ESP32-C3: Standard budget IoT node (RISC-V).
  • ESP32-C6: Next-gen Matter/mesh nodes, Wi-Fi 6, Zigbee/Thread.
  • ESP32-H2: Hub/Home (No Wi-Fi), Zigbee/Thread/BLE.
  • ESP32-P4: Multimedia Powerhouse (No Wireless), H.264, Dual MIPI.

esp32 is a skill published in the GitHub repository ezrover/ESP32-AI-Agent-Skill (35 stars, last pushed 1mo ago), licensed MIT. It adds 97 tokens to every session and 1,847 once invoked, about $0.0005 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.
