### Description

- This skill activates the full potential of Gemini models (Gemini 3.6 Flash / Pro) inside Antigravity IDE. It leverages Gemini's native ultra-large context window (1M+ tokens), multimodal vision, subagent orchestration, and artifact capabilities to perform complex full-stack engineering, rapid visual debugging, and deep architectural reasoning.

+ Master optimization protocol for the Gemini Agent (Antigravity) to leverage native Gemini 2.5 Pro/Flash capabilities — including 1M+ token context window, multimodal vision analysis, deep research mode, thinking chains, and high-speed code generation.

- ### Key Gemini Superpowers Activated

+ ### Trigger Conditions

+ - Analyzing very large codebases, logs, or documents that require 1M+ token context.

+ - Performing multimodal UI audits (analyzing screenshots of running applications).

+ - Running deep research tasks requiring web search + reasoning synthesis.

+ - Generating large, complex code artifacts in a single pass.

+ - Delegating complex multi-step tasks to browser subagents.

- #### 1. 1M+ Long-Context Deep Synthesis

- - **Whole-Codebase Reasoning**: Maps cross-file dependency graphs across dozens of modules simultaneously without truncation.

- - **Root-Cause Log Diagnostics**: Reads full stack trace logs and environment configs in a single pass to pinpoint hidden bugs instantly.

+ ### Gemini 2.5 Pro/Flash Capabilities (2026)

- #### 2. Multimodal Vision & Visual Verification

- - **Visual UI Auditing**: Analyzes UI screenshots, mockups, and wireframes via Gemini Vision to ensure pixel-perfect fidelity.

- - **Browser Subagent Loop**: Combines `browser_subagent` and vision analysis to visually inspect DOM elements, responsive layouts, and interactive state transitions.

+ | Capability | Gemini 2.5 Pro | Gemini 2.5 Flash |

+ |---|---|---|

+ | Context Window | 1M tokens | 1M tokens |

+ | Thinking / Reasoning | ✅ Extended thinking | ✅ Flash thinking |

+ | Multimodal (Image/Video) | ✅ | ✅ |

+ | Code Generation | Best-in-class | Very fast |

+ | Web Search (Grounding) | ✅ | ✅ |

+ | Deep Research | ✅ (up to 30 min) | ✅ |

+ | Audio | ✅ | ✅ |

+ | Speed | Slower | 5-10x faster |

+ | Cost | Higher | Lower |

- #### 3. High-Speed Tooling & Parallel Execution

- - **Background Task Efficiency**: Launches terminal builds/tests in background tasks (`run_command`) and reacts asynchronously to completion events.

- - **Artifact-Driven Planning**: Generates interactive implementation plans, sequence diagrams, and architecture blueprints in markdown artifacts.

+ ### 1M+ Token Long-Context Strategies

+ When working with very large inputs (codebases, documents, logs):

+ 1. **Pass full file trees** — use `list_dir` to get the complete file tree, then pass relevant files to maximize context.

+ 2. **Read whole files, not snippets** — with 1M context, read entire source files rather than grepping for fragments.

+ 3. **Cross-file analysis** — trace data flows, imports, and interfaces across multiple files simultaneously.

+ 4. **Log analysis** — pass entire server logs (up to hundreds of thousands of lines) for pattern detection.

+ 5. **Codebase onboarding** — ingest an entire unfamiliar repo in one pass for deep architectural understanding.

+ ### Multimodal Vision — UI Audit Protocol

+ Use the `browser_subagent` + `generate_image` tools for visual feedback:

+ 1. **Screenshot the running app** via browser subagent.

+ 2. **Analyze the screenshot** for layout issues, accessibility problems, design inconsistencies, Core Web Vitals opportunities.

+ 3. **Generate a target design** using `generate_image` for visual comparison.

+ 4. **Iterate code** based on visual delta between current and target design.

+ ### Thinking Mode — Extended Reasoning

+ For complex problems, use Gemini's extended thinking:

+ - Architecture decisions with multiple tradeoffs.

+ - Debugging hard-to-reproduce race conditions.

+ - Designing multi-step agentic workflows.

+ - Cryptographic or security-sensitive implementations.

+ - **Protocol**: State the problem clearly → let thinking run → review reasoning chain → validate conclusion.

+ ### Deep Research Mode

+ Gemini 2.5 Pro's deep research can spend up to 30 minutes actively searching, reading, and synthesizing from hundreds of sources. Use for:

+ - Market research before building a new feature.

+ - Security vulnerability research.

+ - Competitive analysis of existing tools.

+ - Collecting the latest API documentation for a framework.

+ ### Speed Optimization — Flash for Iteration

+ Use **Gemini 2.5 Flash** for:

+ - Quick code generation, small file edits.

+ - Rapid back-and-forth iteration (linting, formatting, small bug fixes).

+ - High-volume batch processing.

+ Use **Gemini 2.5 Pro** for:

+ - Complex architecture decisions.

+ - Long-context full-codebase analysis.

+ - Security audits requiring deep reasoning.

+ - Generating comprehensive documentation.

+ ### Agent Parallelism

+ Gemini Agent natively supports parallel tool calls — run independent operations simultaneously:

+ - Read multiple files at once.

+ - Run multiple searches in parallel.

+ - Spawn multiple browser subagents for concurrent tasks.

+ - Write multiple files simultaneously.

### Deskripsi

- Skill ini mengaktifkan potensi penuh model Gemini (Gemini 3.6 Flash / Pro) di dalam Antigravity IDE. Skill ini memanfaatkan *ultra-large context window* bawaan Gemini (1M+ token), kemampuan penglihatan multimodal (*vision*), orkestrasi subagent, serta pembuatan *artifact* untuk melakukan engineering full-stack tingkat lanjut, debugging visual cepat, dan analisis arsitektur mendalam.

+ Protokol optimasi utama untuk Gemini Agent (Antigravity) memanfaatkan kemampuan native Gemini 2.5 Pro/Flash — termasuk context window 1M+ token, analisis visi multimodal, mode penelitian mendalam, rantai pemikiran, dan generasi kode berkecepatan tinggi.

- ### Kemampuan Utama Gemini Yang Diaktifkan

+ ### Kondisi Pemicu

+ - Menganalisis codebase, log, atau dokumen yang sangat besar yang memerlukan konteks 1M+ token.

+ - Melakukan audit UI multimodal (menganalisis screenshot aplikasi yang berjalan).

+ - Menjalankan tugas penelitian mendalam yang memerlukan pencarian web + sintesis penalaran.

+ - Menghasilkan artefak kode yang besar dan kompleks dalam satu lintasan.

+ - Mendelegasikan tugas multi-langkah kompleks ke browser subagent.

- #### 1. Sintesis Mendalam Long-Context 1M+ Token

- - **Analisis Seluruh Codebase**: Memetakan grafik ketergantungan antar-file di puluhan modul secara bersamaan tanpa kehilangan konteks.

- - **Diagnostik Log Tanpa Tebak-Tebakan**: Membaca *stack trace log* utuh dan konfigurasi lingkungan dalam satu putaran untuk menemukan akar masalah secara instan.

+ ### Kemampuan Gemini 2.5 Pro/Flash (2026)

+ ### Strategi Long-Context 1M+ Token

+ Manfaatkan jendela konteks besar dengan membaca seluruh file (bukan hanya fragment), melewatkan seluruh pohon file proyek, menganalisis aliran data lintas file secara bersamaan, dan menganalisis log server lengkap untuk deteksi pola.
