SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill provides expert prompt engineering for Faiston NEXO AI agents using Google ADK with Gemini 3.0 Pro, enabling proactive prompt optimization, persona caching, reflection/planning prompts, and A2A conversation generation across agent stacks.

Core Features & Use Cases

  • Proactive prompt optimization for NEXO agents and their cognitive architecture.
  • Persona caching, reflection prompts, and planning prompts to improve agent consistency.
  • Design patterns for System Instruction, User Prompt Templates, and RAG Context Injection.
  • Agent-wide prompts for NEXOAgent, FlashcardsAgent, MindMapAgent, ReflectionAgent, and AudioClassAgent.
  • Brazilian Portuguese tone and accessibility by default.
  • JSON output patterns and robust post-processing to ensure structured results.

Quick Start

Provide a simple example to create a new prompt for a NEXOAgent that generates 5 flashcards from a transcript, ensuring the output is valid JSON.

Frequently Asked Questions about prompt-engineer

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I optimize prompts for AI agents to ensure valid JSON output?

Prompt optimization for AI agents ensures valid JSON output by applying structured System Instruction templates and robust post-processing patterns. This enforces strict formatting rules, preventing parsing errors in downstream applications.

What are reflection and planning prompts in agent cognitive architecture?

Reflection and planning prompts in agent cognitive architecture are design patterns that improve consistency by guiding the model through self-evaluation and step-by-step task breakdown before generating final responses.

How do I implement RAG context injection in agent system instructions?

Implement RAG context injection within agent system instructions by using User Prompt Templates that dynamically insert retrieved context. This ensures the agent grounds its responses in external knowledge accurately.

Can I use this prompt engineering framework for multi-agent A2A conversation generation?

Yes, this prompt engineering framework supports multi-agent A2A conversation generation. It provides specific design patterns for generating consistent communication across NEXOAgent, FlashcardsAgent, and MindMapAgent stacks.

Do I need external software to enforce Brazilian Portuguese tone in agent prompts?

No external software is needed to enforce Brazilian Portuguese tone in agent prompts. The framework applies native language constraints and accessibility rules directly within the prompt design patterns.

What is the best way to structure prompts for a FlashcardsAgent generating study materials?

The best way to structure prompts for a FlashcardsAgent is by combining persona caching with strict JSON output patterns. This ensures the agent consistently generates formatted study materials from transcripts.
