pdt42

Platform design as a language — readable by humans, checkable by machines, guided step by step.

pdt42 keeps a platform design in Markdown files (*.pdt42.md): prose explaining why, and typed blocks forming one consistent model — from arenas and entity-roles to transactions, learning engines, experiences and growth loops. Every canvas of the Platform Design Toolkit is drawn from that model, so the canvases never disagree. Explore, design and grow the platform together with your agent.

npx @pdt42/cli guide            # the method, and where your design stands
npx @pdt42/cli guide step D1    # one step: file, dependencies, how-to, starter template
npx @pdt42/cli next             # what to work on next
npx @pdt42/cli validate         # consistency check (exit 1 on errors)
npx @pdt42/cli serve            # chapters, model boxes and canvases in the browser, live
npx @pdt42/cli build --out site # a static site (--single-file: one HTML page)

Installed globally (npm i -g @pdt42/cli), the command is pdt42. All commands accept --dir <workspace> and --format json.
