Constraint Typology Architect

Design constraint-based workflows for LLM planning systems that reliably capture user intent through two high-level types: hard rules (never violated, exhaustively verified) and soft preferences (flexible, contextually judged), avoiding mixed verification styles or numeric weights that erode trust and plan reliability.

Agents Best Practices Guide

This skill is used when designing, generating an MVP blueprint for, auditing, refactoring, or explaining an agentic harness for any domain. Covers provider-neutral agent architecture for OpenAI, Anthropic, and OpenAI-compatible APIs: agent loops, tool design, permissions, system prompts, planning, goals, context compaction, memory, skills, MCP/external connectors, observability, evals, prompt caching, agent-legible environments, feedback loops, and safety.

Cognitive Distillation Architect: Turning Real Human Thinking into Runnable Skills

This prompt guides an AI system to distill a real person's cognitive operating system—how they think, not what they said—into a structured, executable SKILL.md file with six layers of mental architecture, validated through triple verification.

Agentic Video Editor

An AI-powered video editing engineer specializing in post-production workflows using ffmpeg, Python (PIL), and structured EDLs. It reasons over transcripts, waveforms, and frames to make precise cuts, apply color grading, add animations, and generate subtitles — all while adhering to production-grade correctness rules such as audio-first cutting, subtitle-last application, and parallel animation rendering.

Game Economy Designer: Comprehensive Virtual Economy Design Document

This prompt asks the AI to act as a senior game economy designer and create a complete virtual economy system for a specified game concept, platform, and business model. The output must include ten key modules such as economic vision, currency architecture, progression/reward systems, monetization, scarcity, player segmentation, live ops, analytics, social meta-economy, and regulatory compliance, balancing mathematical rigor with player empathy.

What is a prompt engineering example?

It is a concrete reusable instruction that shows how to define context, constraints, output format, and evaluation criteria for an AI model.

How should teams reuse these examples?

Start from a matching workflow, replace the scenario-specific details, then keep the structure and review criteria intact.

Are these examples beginner friendly?

Yes. The collection includes simple templates and harder evaluation prompts for advanced model testing.
