One Manual, Every AI Tool: AGENTS.md | The Memory Layer, Part 2

Two AI tools, one folder, two different answers. In Part 2 of The Memory Layer, Alex and Josh write the operating manual for your AI brain: one AGENTS.md file that every tool reads first, so a coding agent, a CLI agent, an IDE assistant and a chat app all follow the same rules. You'll learn: Why AGENTS.md is now a shared standard, and how Claude Code, Gemini CLI, Codex, Copilot and Cursor find it One source of truth: pointer files (CLAUDE.md, GEMINI.md) that just say @AGENTS.md What the research says: AI-generated context files hurt, short human rules help, and instruction-following drops as manuals grow Write rules, not a tour: the anatomy of a good manual (a pilot's checklist, not the aircraft manual) Skills: procedures that load only when needed (recipe cards in a drawer) Page properties and an Obsidian Bases review queue The token budget, explained with a Formula One car Why your manual is an attack surface, and how to protect it Lab 2: write a manual and test it with two different tools Slides (PDF), lab, research brief and transcript: https://github.com/Kinvecta/the-memor...
