Mirrors the multi-harness reframing of the project itself. CLAUDE.md is
Claude-Code-specific by name; AGENTS.md is the multi-harness convention
that Codex, Cursor, Gemini CLI, GitHub Copilot, and most other Agent
Skills hosts also read. The canonical content belongs in the file
multi-harness tooling expects.
git mv preserves history — the Orientation section and everything else
that was in CLAUDE.md is now tracked under AGENTS.md, with full blame
continuity. The new CLAUDE.md is a one-line `@AGENTS.md` reference so
Claude Code continues to load the content (it follows @ references).
Codex CLI reads AGENTS.md for repo-level context the way Claude Code reads CLAUDE.md. Delegate to the existing CLAUDE.md so both harnesses share one source of project instructions.
