Gemini

This wraps the Gemini CLI for handling code reviews, architectural analysis, and anything requiring massive context windows over 200k tokens. It defaults to Gemini 3 Pro, which apparently scores 76.2% on SWE-bench and handles up to 1M tokens of input. The main gotcha is approval modes: you must use yolo mode for background execution in Claude Code or it'll hang indefinitely waiting for interactive prompts you can't provide. The skill asks which model you want upfront (3 Pro for reasoning, 3 Flash for speed, or legacy 2.5 models), runs the analysis, and reminds you to start a new session for follow-ups since there's no built-in resume. Honestly most useful when you need to throw an entire codebase at an LLM and get back coherent analysis without token limit anxiety.

When to Use Gemini

WHEN ASKED TO BE ACTIVATED
Code Review: Comprehensive code reviews across multiple files
Plan Review: Analyzing architectural plans, technical specifications, or project roadmaps
Big Context Processing: Tasks requiring >200k tokens of context (entire codebases, documentation sets)
Multi-file Analysis: Understanding relationships and patterns across many files

⚠️ Critical: Background/Non-Interactive Mode Warning

NEVER use --approval-mode default in background or non-interactive shells (like Claude Code tool calls). It will hang indefinitely waiting for approval prompts that cannot be provided.

For automated/background reviews:

✅ Use --approval-mode yolo for fully automated execution
✅ OR wrap with timeout: timeout 300 gemini ...
❌ NEVER use --approval-mode default without interactive terminal

Symptoms of hung Gemini:

Process running 20+ minutes with 0% CPU usage
No network activity
Process state shows 'S' (sleeping)

Fix hung process:

# Check if hung
ps aux | grep gemini | grep -v grep

# Kill if necessary
pkill -9 -f "gemini.*gemini-3-pro-preview"
