Bootcamp · Module 1 · Lesson 1 of 3
Start with AGENTS.md (or the equivalent)
One short file the agent reads every session beats a long chat you forget to paste.
Put project commands, forbidden paths and review expectations in AGENTS.md (read by Codex and Cursor), CLAUDE.md (Claude Code) or .cursor/rules so every session starts with the same constraints.
Keep it short. Long rule files crowd out the code the agent needs to see.
Tool-neutral habit: if a teammate uses a different agent, the same facts should live in a file both can load.
