Gemini Cli
Orchestrate Google Gemini CLI for code analysis, web research, and parallel AI tasks
What You Can Do
This skill lets you leverage Gemini CLI as a complementary AI tool within your Claude-driven workflows. You can request code reviews from a different AI perspective, access current web information through Google Search integration, analyze complex codebase architectures, run parallel code generation tasks, and handle specialized operations like test suite generation or documentation—all while Claude coordinates the orchestration and results integration.
Features
Run generated code through Gemini for alternative perspective and bug detection
Access current web information, API documentation, and latest library versions
Use Gemini's codebase_investigator tool to map dependencies and understand unfamiliar code
Offload tasks to Gemini while Claude continues other work simultaneously
Generate test suites, JSDoc documentation, and code translations via Gemini
Execute Gemini operations with --yolo flag for seamless workflow integration
Receive clean, parseable results optimized for further processing
Control Gemini CLI operations through simple bash commands within Claude workflows
Example Output
Example 1: Code Review with Second Opinion
You submit generated authentication logic to Gemini for security review. Gemini identifies a timing vulnerability in the token validation that Claude missed, returning:
- Vulnerability: "Token expiry check occurs after signature verification"
- Fix: Reorder validation steps to check expiry first
- Severity: High
Example 2: Current API Documentation Lookup
You ask Gemini for the latest Firebase SDK syntax. Via Google Search, Gemini retrieves current documentation and returns:
- Latest Firebase Admin SDK v12.0.0 initialization pattern
- Breaking changes from v11 → v12 migration
- Code example with async/await syntax
Example 3: Codebase Dependency Mapping
You run Gemini's codebase_investigator on an unfamiliar Node.js monorepo. Output includes:
- File dependency graph showing cross-package imports
- Entry points and initialization sequence
- Shared utilities and their consumers
What's Included
- SKILL.md: Complete integration instructions with command patterns, flags, and tool configurations
- Installation verification script: One-line command to confirm gemini CLI (v0.16.0+) is available
- Bash command templates: Ready-to-use command patterns for code review, search queries, and codebase analysis workflows
- Use case decision tree: Framework for determining when to invoke Gemini vs. handling tasks in Claude
- Error handling checklist: Troubleshooting guide for rate limits, authentication, and command failures

Best For
- Cross-AI security audits — Submit sensitive code to Gemini for alternative vulnerability detection perspective
- Research-dependent tasks — Retrieve current library versions, API changes, and latest best practices via Google Search
- Complex codebase onboarding — Map unfamiliar architectures and dependency graphs quickly using codebase_investigator
- High-volume code generation — Run multiple generation tasks in parallel (test suites, documentation, translations)
- Specialized output formats — Generate JSDoc documentation, unit test scaffolding, and language-specific code translations
You might also like
You can systematize pixel art animation organization by analyzing your game's animation requirements, calculating optimal sprite sheet dimensions, planning color palette strategies, and generating frame sequence documentation. Claude helps you move from manual guesswork to data-driven asset optimization, reducing revisions during engine integration and saving hours on layout iterations.
You'll architect complete HUD design systems that establish consistency across multi-screen game interfaces. This skill generates design tokens, component hierarchies, responsive behavior specifications, and accessibility compliance matrices—bridging the gap between design intent and developer implementation. You'll produce unambiguous handoff documentation that reduces designer-developer friction and ensures WCAG 2.1 AA accessibility compliance.
You can rapidly categorize network issues (latency vs. sync vs. bandwidth), instrument networked game systems for visibility, identify common netcode anti-patterns by their telltale signatures, generate reproducible test cases for various network conditions, debug server-client state reconciliation failures, and profile network code paths to optimize bandwidth. This skill transforms vague player reports into actionable diagnosis data that pinpoints whether desynchronization, rubber-banding, packet loss, or authority violations are the root cause.
Get a step-by-step launch strategy tailored to your specific business model. This skill analyzes your offering, target market, and resources to create a realistic, phased launch plan with timing, marketing tactics, and success metrics. You'll receive competitor analysis, positioning recommendations, and a 90-day execution roadmap.
You can map puzzle constraints across multiple difficulty dimensions—mechanical complexity, cognitive load, time pressure, and solution discovery paths—then translate subjective difficulty assessments into measurable parameters. This allows you to identify difficulty spikes before production, communicate design intent clearly to your team, and iterate on puzzle balance using playtester data and performance metrics.
You can convert high-level gameplay design intent into production-ready technical specifications that account for system interactions, edge cases, and balance concerns. Claude helps you identify logical inconsistencies, generate exhaustive state machines for complex mechanics, and create stress-test scenarios that expose vulnerabilities before your team encounters them in development.
You can conduct comprehensive accessibility audits of game UI/UX systems using WCAG 2.1 Level AA standards as your baseline while accounting for platform-specific requirements (console, PC, mobile) and gaming-specific barriers like motion-induced discomfort, color-reliant communication, rapid interactions, and audio-dependent information. The skill generates prioritized remediation strategies that balance accessibility improvements with gameplay integrity, enabling you to document compliance gaps and create actionable improvement plans for your development team.
You can systematically design menu hierarchies and interaction flows that feel responsive and intuitive for game players. This skill helps you map complete player journeys through nested menus, define state transitions for complex scenarios (like pause-while-paused), establish consistent interaction patterns across your UI, and identify edge cases before implementation. You'll document specifications that programmers and junior designers can follow, ensuring accessible navigation that respects controller/keyboard constraints and 100ms feedback expectations.
