Gemini CLI Integration

Overview

Execute Gemini CLI commands with support for multiple models and flexible prompt input. Integrates Google's Gemini AI models into Claude Code workflows.

When to Use

• Complex reasoning tasks requiring advanced AI capabilities
• Code generation and analysis with Gemini models
• Tasks requiring Google's latest AI technology
• Alternative perspective on code problems

Usage

Mandatory: Run via uv with fixed timeout 7200000ms (foreground):

uv run ~/.claude/skills/gemini/scripts/gemini.py "<prompt>" [working_dir]

Optional (direct execution or using Python):

~/.claude/skills/gemini/scripts/gemini.py "<prompt>" [working_dir]
# or
python3 ~/.claude/skills/gemini/scripts/gemini.py "<prompt>" [working_dir]

Environment Variables

• GEMINI_MODEL: Configure model (default: gemini-3-pro-preview)
  • Example: export GEMINI_MODEL=gemini-3

Timeout Control

• Fixed: 7200000 milliseconds (2 hours), immutable
• Bash tool: Always set timeout: 7200000 for double protection

Parameters

• prompt (required): Task prompt or question
• working_dir (optional): Working directory (default: current directory)

Return Format

Plain text output from Gemini:

Model response text here...

Error format (stderr):

ERROR: Error message

Invocation Pattern

When calling via Bash tool, always include the timeout parameter:

Bash tool parameters:
- command: uv run ~/.claude/skills/gemini/scripts/gemini.py "<prompt>"
- timeout: 7200000
- description: <brief description of the task>

Alternatives:

# Direct execution (simplest)
- command: ~/.claude/skills/gemini/scripts/gemini.py "<prompt>"

# Using python3
- command: python3 ~/.claude/skills/gemini/scripts/gemini.py "<prompt>"

Examples

Basic query:

uv run ~/.claude/skills/gemini/scripts/gemini.py "explain quantum computing"
# timeout: 7200000

Code analysis:

uv run ~/.claude/skills/gemini/scripts/gemini.py "review this code for security issues: $(cat app.py)"
# timeout: 7200000

With specific working directory:

uv run ~/.claude/skills/gemini/scripts/gemini.py "analyze project structure" "/path/to/project"
# timeout: 7200000

Using python3 directly (alternative):

python3 ~/.claude/skills/gemini/scripts/gemini.py "your prompt here"

Notes

• Recommended: Use uv run for automatic Python environment management (requires uv installed)
• Alternative: Direct execution ./gemini.py (uses system Python via shebang)
• Python implementation using standard library (zero dependencies)
• Cross-platform compatible (Windows/macOS/Linux)
• PEP 723 compliant (inline script metadata)
• Requires Gemini CLI installed and authenticated
• Supports all Gemini model variants (configure via GEMINI_MODEL environment variable)
• Output is streamed directly from Gemini CLI
