At a glance

Compile ESPRotary examples with arduino-cli to verify they build.

  • Tasks that involve Embedded systems
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Compile is an agent skill from LennartHennigs/ESPRotary. Compile ESPRotary examples with arduino-cli to verify they build. Pass an example name, or leave blank to compile all examples for the ESP8266 D1.

Its SKILL.md is about 330 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. It works with ESP32. The repository describes itself as: Arduino/ESP library to simplify reading rotary encoder data. The licence is MIT.

When your agent uses it

  • Tasks that involve Embedded systems

Example prompts

  • “/compile”

What it can do on your machine

Read from SKILL.md and the folder at commit 2d029ba. 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 bash).

    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

Compile loads about 329 tokens when it runs. Until then it costs about 39 tokens; SKILL.md has 131 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~39
When it runs · the whole SKILL.md, loaded when a task matches
~329

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.

Compile ESPRotary examples with arduino-cli to verify they build. Pass an example name, or leave blank to compile all examples for the ESP8266 D1.

Compile ESPRotary examples to verify they build cleanly.

The library targets Arduino, ESP8266, and ESP32. The primary verification board is the ESP8266 D1 (esp8266:esp8266:d1).

Parse $ARGUMENTS:

  • If a specific example name is given, find the matching .ino under examples/ and compile just that one.
  • If nothing (or "all") is given, compile every example under examples/.

Compile each with:

bash
arduino-cli compile --fqbn esp8266:esp8266:d1 examples/<Name>

If a default-FQBN compile fails on build-option grounds, use the fuller FQBN: esp8266:esp8266:d1:xtal=80,vt=flash,exception=disabled,ssl=all,eesz=4M2M,ip=lm2f,dbg=Disabled,lvl=None____,wipe=none,baud=921600

Notes

  • examples/SimpleCounterWithButton also requires the Button2 library to be installed; if it's missing, note that rather than reporting a real failure.
  • The ESP32Interrupt example targets ESP32 — compile it with --fqbn esp32:esp32:esp32 if an ESP32 core is installed; otherwise skip and say so.

Report any compiler errors clearly, quoting the relevant error lines. If compilation is clean, confirm which examples passed.

Questions about Compile

What does Compile do?

Compile ESPRotary examples with arduino-cli to verify they build. Compile is an agent skill from LennartHennigs/ESPRotary. Compile ESPRotary examples with arduino-cli to verify they build.

When should I use Compile?

Compile fits situations like: tasks that involve Embedded systems.

How do I install Compile in Claude Code?

Run `npx skills add LennartHennigs/ESPRotary --skill compile -a claude-code`. Or copy the skill folder (.claude/skills/compile in LennartHennigs/ESPRotary) into .claude/skills/compile in your project. Claude Code loads it when a task matches its description.

How do I install Compile in Codex?

Run `npx skills add LennartHennigs/ESPRotary --skill compile -a codex`. Or copy the skill folder (.claude/skills/compile in LennartHennigs/ESPRotary) into .agents/skills/compile in your project. Codex loads it when a task matches its description.

Can I use Compile in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add LennartHennigs/ESPRotary --skill compile -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/compile, .gemini/skills/compile, .github/skills/compile and .opencode/skills/compile in your project.

What does Compile need to run?

SKILL.md names no scripts, command-line tools or credentials: Compile is instructions for the agent only.

Does Compile access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Compile safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.

What licence does Compile use?

Compile is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Compile use?

About 329 tokens (SKILL.md is roughly 1.3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.

What are the alternatives to Compile?

Skills that share tags, products or a category with Compile: RuView Hardware Setup (ruvnet/RuView, 97k stars), Esp32 Firmware Engineer (alxv2016/folloup-sticky, 117 stars), RuView mmWave Radar Setup (ruvnet/RuView, 97k stars) and Embedded Debug (FastLED/FastLED, 7.5k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
