Plan-first reasoning is what makes coding agents like Claude Code feel deliberate. Before touching any file, the agent writes a multi-step plan, commits to it, then executes one step at a time. Without it, the agent meanders. With it, you get focused work and a paper trail you can read. On Digitorn plan-first is a runtime rule, not a prompt instruction, which means it survives compaction and sloppy prompt edits.
Engineering notes from the Digitorn team. No marketing, no launch announcements, no "10 prompts that will change your life". Just the things we write that we'd want to read.
