gemini
Comprehensive code review and large-context analysis using Gemini 3 Pro with flexible approval modes.
- Supports five Gemini models ranging from flagship reasoning (Gemini 3 Pro) to cost-optimized alternatives, with 1M token input windows for analyzing entire codebases and documentation sets
- Three approval modes:
defaultfor interactive terminal prompts,auto_editfor auto-approving code suggestions, andyolofor fully automated background execution - Critical safety requirement: use
--approval-mode yoloor timeout wrapper in non-interactive shells to prevent indefinite hangs waiting for approval prompts - Designed for code reviews, architectural plan analysis, multi-file pattern detection, and tasks exceeding 200k tokens of context
Gemini Skill Guide
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 yolofor fully automated execution - ✅ OR wrap with timeout:
timeout 300 gemini ... - ❌ NEVER use
--approval-mode defaultwithout interactive terminal

mermaid-diagrams
Comprehensive guide for creating software diagrams using Mermaid syntax. Use when users need to create, visualize, or document software through diagrams including class diagrams (domain modeling, object-oriented design), sequence diagrams (application flows, API interactions, code execution), flowcharts (processes, algorithms, user journeys), entity relationship diagrams (database schemas), C4 architecture diagrams (system context, containers, components), state diagrams, git graphs, pie charts, gantt charts, or any other diagram type. Triggers include requests to "diagram", "visualize", "model", "map out", "show the flow", or when explaining system architecture, database design, code structure, or user/application flows.
