Quick Install

# Clone the repository
git clone https://github.com/alirezarezvani/claude-skills.git
cd claude-skills

# Run the Gemini setup script (converts and installs all skills)
./scripts/gemini-install.sh

# Or convert individual skills
./scripts/convert.sh --skill frontend-design --tool gemini
./scripts/convert.sh --skill autoresearch-agent --tool gemini

How It Works

Gemini CLI reads agent skills from .gemini/skills/<skill-name>/SKILL.md in your project directory. The setup script converts all skills to Gemini-compatible format, including gemini-extension.json for the extension registry.

Why Use Skills with Gemini CLI?

Gemini CLI's free tier gives you unlimited evaluation calls — perfect for:

• Autoresearch loops — run overnight experiments with zero API cost
• Content optimization — LLM-judge evaluators for headlines, copy, prompts
• Code review — systematic multi-pass reviews without burning tokens

Free Evaluators with Gemini

The autoresearch-agent skill includes LLM judge evaluators that work with Gemini's free tier:

# Set up an autoresearch experiment using Gemini as the evaluator
python scripts/setup_experiment.py \
  --domain marketing \
  --name headline-optimization \
  --target content/headlines.md \
  --eval "python evaluate.py" \
  --metric ctr_score \
  --direction higher \
  --evaluator llm_judge_content

# The evaluator calls gemini CLI for scoring — free!
