How I Set Up Droid, Claude Code, and Codex with Shared Configuration

I use AI coding agents daily — Droid, Claude Code, and Codex. I prefer Droid at the moment, but my setup is basically the same for all 3. Because I use all 3 and my configuration is basic, I have it set up so that there is just 1 set of configuration files stored in Dropbox. CONFIGURATION The configuration lives in ~/.config/coding-agents/ with softlinks: * AGENTS.md — softlinked to both CLAUDE.md (for Claude Code) and AGENTS.md (for Droid/Codex) * skills/ — softlinked for all 3 agents * commands/ — softlinked to commands/ for Droid and Claude Code, and prompts/ for Codex This way I maintain one set of files and all 3 agents stay in sync.
