Behavior Intelligence · Scoped answers
Repository and project guidance is documented through different mechanisms. Codex uses AGENTS.md files, Claude Code uses scoped CLAUDE.md instructions, Gemini CLI uses hierarchical GEMINI.md context, Cursor uses project rules, and ChatGPT Projects can carry project instructions. The selected Claude evidence covers a different chat-product surface, so repository instructions fall outside its scope.
Six product answers
Choose where team and project guidance should live without treating unlike instruction mechanisms as interchangeable.
Codex supports repository-scoped guidance through AGENTS.md and AGENTS.override.md in the documented context assembly.
The selected evidence covers dated Claude chat-product prompts. Repository instruction handling belongs to the separately modeled Claude Code product and falls outside the represented surface.
Claude Code documents managed, user, project, and local CLAUDE.md instruction scopes for coding-agent work.
Gemini CLI documents global, workspace, and just-in-time GEMINI.md files as hierarchical project and task context.
ChatGPT Projects can carry project-specific instructions alongside project chats and uploaded files.
Cursor documents version-controlled project rules under .cursor/rules as repository and path-aware instruction context.
