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), install/search/list cores (platforms) and libraries, or configure Arduino CLI. Triggers on phrases like "arduino-cli", "compile sketch", "upload arduino", "install arduino core", or "arduino library".

Best use case

arduino-cli is best used when you need a repeatable AI agent workflow instead of a one-off prompt.

Teams using arduino-cli should expect a more consistent output, faster repeated execution, less prompt rewriting.

When to use this skill

You want a reusable workflow that can be run more than once with consistent structure.

When not to use this skill

You only need a quick one-off answer and do not need a reusable workflow.
You cannot install or maintain the underlying files, dependencies, or repository context.

# 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`):
```bash
arduino-cli config init
```

Update the local cache of available platforms and libraries (do this first!):
```bash
arduino-cli core update-index
```

### 2. Board Management
List connected boards to find the port and FQBN (Fully Qualified Board Name):
```bash
arduino-cli board list
```

List all supported boards and their FQBN strings:
```bash
arduino-cli board listall <search_term>
```

### 3. Core (Platform) Management
Search for a core:
```bash
arduino-cli core search <keyword>
```

Install a core using its ID (e.g., `arduino:samd`):
```bash
arduino-cli core install <core_id>
```

List installed cores:
```bash
arduino-cli core list
```

### 4. Sketch Workflow
Create a new sketch:
```bash
arduino-cli sketch new <SketchName>
```

Compile a sketch (requires the board's FQBN):
```bash
arduino-cli compile --fqbn <FQBN> <SketchName>
```
*Example:* `arduino-cli compile --fqbn arduino:samd:mkr1000 MyFirstSketch`

Upload a sketch to a connected board:
```bash
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:
```bash
arduino-cli lib search <keyword>
```

Install a library:
```bash
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:

```bash
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`)*

Remove signs of AI-generated writing from text. Use when editing or reviewing text to make it sound more natural and human-written. Based on Wikipedia's comprehensive "Signs of AI writing" guide. Detects and fixes patterns including: inflated symbolism, promotional language, superficial -ing analyses, vague attributions, em dash overuse, rule of three, AI vocabulary words, negative parallelisms, and excessive conjunctive phrases.

Content & Documentation

find-skills

3891

from openclaw/skills

Helps users discover and install agent skills when they ask questions like "how do I do X", "find a skill for X", "is there a skill that can...", or express interest in extending capabilities. This skill should be used when the user is looking for functionality that might exist as an installable skill.

General Utilities

Workflow & Productivity

Meeting Prep

3891

from openclaw/skills

Never walk into a meeting unprepared again. Your agent researches all attendees before calendar events—pulling LinkedIn profiles, recent company news, mutual connections, and conversation starters. Generates a briefing doc with talking points, icebreakers, and context so you show up informed and confident. Triggered automatically before meetings or on-demand. Configure research depth, advance timing, and output format. Walking into meetings blind is amateur hour—missed connections, generic small talk, zero leverage. Use when setting up meeting intelligence, researching specific attendees, generating pre-meeting briefs, or automating your prep workflow.

Workflow & Productivity

self-improvement

3891

from openclaw/skills

Captures learnings, errors, and corrections to enable continuous improvement. Use when: (1) A command or operation fails unexpectedly, (2) User corrects Claude ('No, that's wrong...', 'Actually...'), (3) User requests a capability that doesn't exist, (4) An external API or tool fails, (5) Claude realizes its knowledge is outdated or incorrect, (6) A better approach is discovered for a recurring task. Also review learnings before major tasks.
