🤖 Agent Skills — by Use AI with Tech Dad

A curated collection of open-source agent skills for AI coding assistants. Each skill is a self-contained package of instructions, scripts, and resources that teaches an AI agent how to perform a specialized task — reliably and repeatably.

📺 YouTube Channel: Use AI with Tech Dad Follow along as we build, explain, and demo each skill live.

What Are Agent Skills?

Skills are folders that contain a SKILL.md file (with YAML frontmatter) plus any supporting scripts, assets, and resources. When an AI agent loads a skill, it gains the ability to perform that task using the provided instructions — whether that's removing watermarks from images, generating documents, automating workflows, or anything else you can teach it.

my-skill/
├── SKILL.md          # Instructions + metadata (required)
├── scripts/          # Helper scripts (optional)
├── resources/        # Documentation, references (optional)
└── examples/         # Usage examples (optional)

Skills follow the open Agent Skills specification.

Quick Start

Using with Any AI Coding Agent

1. Clone or download this repository
2. Point your agent to the skill folder you want to use
3. The agent reads SKILL.md and follows the instructions automatically

git clone https://github.com/useaitechdad/agent-skills.git
cd agent-skills

Example: Gemini Watermark Remover

Tell your agent:

"Remove the watermark from this Gemini image: /path/to/my_image.png"

The agent will read SKILL.md, install dependencies if needed, run the Python script, and report the result.

Or run it manually:

cd gemini_watermark_remover_agent_skill
pip install -r scripts/requirements.txt
python scripts/remove_watermark.py /path/to/image.png --output /path/to/clean.png

Creating Your Own Skills

Use the basic template below as a starting point:

---
name: my-skill-name
description: A clear description of what this skill does and when to use it
---

# My Skill Name

[Add your instructions here that the agent will follow when this skill is active]

## Workflow
1. Step one
2. Step two

## Examples
- Example usage 1
- Example usage 2

## Constraints
- Constraint 1
- Constraint 2

The frontmatter requires only two fields:

• name — A unique identifier (lowercase, hyphens for spaces)
• description — What the skill does and when to use it

Disclaimer

These skills are provided for educational and personal use. They demonstrate image processing techniques using standard open-source libraries (NumPy, Pillow). Always test skills thoroughly in your own environment before relying on them for critical tasks.

Important: The watermark remover skill only removes the visible logo overlay using reverse alpha blending — a standard image processing technique. It does not remove or alter Google's invisible SynthID provenance metadata embedded in AI-generated images.
