The original title is: "No Baked-In Behavior: Why Your AI Agent's System Prompt Should Be Yours"

Short summary

Most AI coding agents ship with hidden system prompts and fixed tool definitions that users cannot inspect or modify, making debugging a black-box exercise. Jean2 takes a different approach: no default system prompt, no fixed tools, and full transparency through composable config files (AGENTS.md, MEMORY.md, USER.md, skills). Every piece of the prompt is a readable, editable, version-controllable file on disk, giving developers complete control over agent behavior.

• •AI coding agents like Claude Code and Cursor ship with hidden system prompts users can't change
• •Jean2 ships blank with composable, version-controllable config files for full prompt transparency
• •Approach solves debugging, prompt conflicts, and unwanted baked-in behaviors
