Gemini CLIAbout this skill
Expert prompt engineering for building AI agents via Claude, GPT, and Gemini APIs. Triggers when: writing or editing system prompts, tool descriptions, agent instructions, function calling schemas, tool response design, context engineering, agentic system design, or discussing prompt quality for any LLM API. Also triggers on: prompt optimization, tool-use accuracy, cross-provider compatibility, or prompt review. Examples: 'improve the system prompt', 'write a tool description', 'the agent keeps calling the wrong tool', 'make this work on Gemini too', 'the tool returns too much data', 'design the agent context flow'.
