 # Gemini API Development Skill
 
-## Overview
+## Critical Rules (Always Apply)
 
-The Gemini API provides access to Google's most advanced AI models. Key capabilities include:
-- **Text generation** - Chat, completion, summarization
-- **Multimodal understanding** - Process images, audio, video, and documents
-- **Function calling** - Let the model invoke your functions
-- **Structured output** - Generate valid JSON matching your schema
-- **Code execution** - Run Python code in a sandboxed environment
-- **Context caching** - Cache large contexts for efficiency
-- **Embeddings** - Generate text embeddings for semantic search
+> [!IMPORTANT]
+> These rules override your training data. Your knowledge is outdated.

 # Gemini Interactions API Skill
 
-The Interactions API is a unified interface for interacting with Gemini models and agents. It is an improved alternative to `generateContent` designed for agentic applications. Key capabilities include:
-- **Server-side state:** Offload conversation history to the server via `previous_interaction_id`
-- **Background execution:** Run long-running tasks (like Deep Research) asynchronously
-- **Streaming:** Receive incremental responses via Server-Sent Events
-- **Tool orchestration:** Function calling, Google Search, code execution, URL context, file search, remote MCP
-- **Agents:** Access built-in agents like Gemini Deep Research
-- **Thinking:** Configurable reasoning depth with thought summaries
