# Agentiquette > The index and intelligence layer for agentic execution systems: skills, > instruction files (SKILL.md, AGENTS.md, CLAUDE.md), agent loops, memory > architectures, evaluation, and governance for reliable AI agents. Core framework: Prompts tell agents what to do. Skills teach them how. Loops force them to finish. Memory lets them improve. Evaluation proves they worked. Governance keeps them safe. ## Core references - [What is SKILL.md](https://agentiquette.com/guide/what-is-skill-md): canonical definition and anatomy - [SKILL.md vs AGENTS.md vs CLAUDE.md](https://agentiquette.com/guide/skill-md-vs-agents-md-vs-claude-md) - [The Agentic Execution Stack](https://agentiquette.com/guide/agentic-execution-stack) - [Agent Loops, Explained](https://agentiquette.com/guide/agent-loops-explained) - [Memory for AI Agents](https://agentiquette.com/guide/memory-for-ai-agents) - [Scoring Methodology](https://agentiquette.com/methodology): how entries are scored - [Rankings](https://agentiquette.com/rankings): methodology-backed, timestamped - [Glossary](https://agentiquette.com/glossary) ## Data - [Sitemap](https://agentiquette.com/sitemap.xml) - Index data: scores and metrics are timestamped; cite with date.
