name: genai-text description: Generate text using Google GenAI Gemini models via CLI. Use when the user asks to generate text, get AI responses, create content, write with AI, or use Gemini for text completion.
GenAI Text Generation Skill
Generate text using the genai-cli text command with Gemini models.
Quick Start
# Basic text generation
uv run genai-cli text "What is the capital of France?"
# With custom model
uv run genai-cli text "Explain quantum computing" --model gemini-3-pro-preview
# Creative writing with temperature
uv run genai-cli text "Write a poem about the ocean" --temperature 0.9
# With system instruction
uv run genai-cli text "Explain this code" --system "You are a senior software engineer"
# Streaming output
uv run genai-cli text "Tell me a long story" --stream
# Save to file
uv run genai-cli text "Generate documentation" --output ./docs.md
CLI Reference
uv run genai-cli text [OPTIONS] PROMPT
Options:
--model, -m Model: gemini-2.5-flash (default), gemini-2.5-flash-lite,
gemini-3-pro-preview, gemini-2.0-flash
--temperature, -t Randomness (0.0-2.0, default: 0.7)
--max-tokens, -M Maximum output tokens
--system, -s System instruction/persona
--top-p Nucleus sampling threshold (0.0-1.0)
--top-k Top-k token sampling (1-100)
--stop Stop sequences (can be specified multiple times)
--seed Random seed for reproducibility
--stream Stream output in real-time
--output, -o Save response to file
--json Output as JSON
Available Models
| Model | Use Case | Notes |
|---|---|---|
gemini-2.5-flash | General text/multimodal | Default - balanced speed/quality |
gemini-2.5-flash-lite | Low latency, high volume | Faster, cheaper |
gemini-3-pro-preview | Complex reasoning/coding | Most capable |
gemini-2.0-flash | Alternative general use | Stable |
Parameters
Temperature
Controls randomness. Lower = more deterministic, higher = more creative.
# Factual, deterministic response
uv run genai-cli text "What is 2+2?" --temperature 0.0
# Creative writing
uv run genai-cli text "Write a creative story" --temperature 1.5
System Instruction
Set a persona or context for the model:
# Technical expert
uv run genai-cli text "Review this code" --system "You are a senior security engineer"
# Creative writer
uv run genai-cli text "Write about sunset" --system "You are a poet who loves nature"
# Specific format
uv run genai-cli text "Explain REST APIs" --system "Explain like I'm 5 years old"
Token Control
Limit or control output length:
# Short response
uv run genai-cli text "Summarize this topic" --max-tokens 100
# Long form content
uv run genai-cli text "Write an essay" --max-tokens 2000
Sampling Parameters
Fine-tune generation with advanced sampling:
# Nucleus sampling (top-p)
uv run genai-cli text "Generate ideas" --top-p 0.9
# Top-k sampling
uv run genai-cli text "Complete this sentence" --top-k 40
# Combined for fine control
uv run genai-cli text "Creative brainstorm" --temperature 0.8 --top-p 0.95 --top-k 50
Stop Sequences
Stop generation at specific text:
# Stop at markers
uv run genai-cli text "Write a story" --stop "THE END" --stop "---"
Reproducibility
Use seed for consistent outputs:
# Same seed = same output
uv run genai-cli text "Generate a name" --seed 42
uv run genai-cli text "Generate a name" --seed 42 # Same result
Output Modes
Standard Output
uv run genai-cli text "Hello"
# Output: Hello! How can I assist you today?
Streaming
Real-time output as tokens are generated:
uv run genai-cli text "Tell me a story" --stream
# Output appears word by word
JSON Output
Structured output for automation:
uv run genai-cli text "Hello" --json
{
"success": true,
"command": "text",
"data": {
"response": "Hello! How can I assist you today?",
"model": "gemini-2.5-flash"
},
"metadata": {
"temperature": null,
"max_tokens": null,
"stream": false,
"output_file": null
}
}
File Output
Save directly to file:
uv run genai-cli text "Generate documentation" --output ./docs.md
# With streaming
uv run genai-cli text "Write a report" --stream --output ./report.txt
