Arduino CLI

Provides commands and workflows for Arduino CLI. Use when the user wants to create, compile, or upload Arduino sketches, manage boards (list, attach), instal...

Security Scan

The skill is an instruction-only helper for using arduino-cli and is internally consistent, but it omits declaring that the arduino-cli binary must be present and reminds you that installing third‑party cores pulls code from external URLs and uses serial ports.

Purpose & Capability

The skill's name and description match the instructions (commands for arduino-cli). However, the skill does not declare that the arduino-cli binary is required even though every command assumes it is installed on PATH — this is a minor incoherence (missing declared dependency) rather than a functional mismatch.

Instruction Scope

Instructions stay within the stated purpose (create, compile, upload sketches, manage cores/libraries). They reference the usual config path (~/.arduino15/arduino-cli.yaml), local serial ports (e.g., /dev/ttyACM0), and show how to add third‑party core URLs — all expected. Note: installing third‑party cores means the tool will fetch code from external URLs; the skill's text does not warn about verifying those sources.

Install Mechanism

No install spec and no code files — lowest-risk instruction-only skill. Nothing will be written to disk by the skill itself.

Credentials

No environment variables, credentials, or config paths are requested beyond normal references to the user's Arduino config and serial ports; these are appropriate for the claimed functionality.

Persistence & Privilege

Skill is not always-on and does not request elevated or persistent privileges. It does not modify other skills or system-wide settings according to the provided content.

Assessment

This is an instruction-only helper for the arduino-cli tool and appears coherent. Before using it: (1) make sure arduino-cli is installed from a trusted source (the skill assumes the binary exists but doesn't declare it), (2) be aware that upload commands access local serial ports (you may need permission or to run as a user in the dialout/tty group), and (3) when adding third‑party core URLs, verify those URLs (they cause the CLI to download and install platform code). If you need the skill to install arduino-cli for you, look for or request an install spec that uses an official release source.

Arduino CLI Skill

This skill provides guidance for using the arduino-cli to manage Arduino projects, boards, cores, and libraries from the command line.

Quick Reference

1. Configuration & Setup

Initialize the configuration file (usually in ~/.arduino15/arduino-cli.yaml):

arduino-cli config init

Update the local cache of available platforms and libraries (do this first!):

arduino-cli core update-index

2. Board Management

List connected boards to find the port and FQBN (Fully Qualified Board Name):

arduino-cli board list

List all supported boards and their FQBN strings:

arduino-cli board listall <search_term>

3. Core (Platform) Management

Search for a core:

arduino-cli core search <keyword>

Install a core using its ID (e.g., arduino:samd):

arduino-cli core install <core_id>

List installed cores:

arduino-cli core list

4. Sketch Workflow

Create a new sketch:

arduino-cli sketch new <SketchName>

Compile a sketch (requires the board's FQBN):

arduino-cli compile --fqbn <FQBN> <SketchName>

Example: arduino-cli compile --fqbn arduino:samd:mkr1000 MyFirstSketch

Upload a sketch to a connected board:

arduino-cli upload -p <port> --fqbn <FQBN> <SketchName>

Example: arduino-cli upload -p /dev/ttyACM0 --fqbn arduino:samd:mkr1000 MyFirstSketch

5. Library Management

Search for a library:

arduino-cli lib search <keyword>

Install a library:

arduino-cli lib install "<Library Name>"

Adding 3rd Party Cores (e.g., ESP8266)

To install 3rd party cores, pass the --additional-urls flag to your core commands:

arduino-cli core update-index --additional-urls https://arduino.esp8266.com/stable/package_esp8266com_index.json
arduino-cli core install esp8266:esp8266 --additional-urls https://arduino.esp8266.com/stable/package_esp8266com_index.json

(Alternatively, these URLs can be added to the board_manager.additional_urls array in arduino-cli.yaml)
