A stack-agnostic CLI workflow for AI-assisted software development: PRD → Design → Plan → Implement → QA → Compliance → Archive. Human-driven by design, with auditable artifacts at every transition. Datarim is the operational backbone we use to ship every other product in the ecosystem — and we dogfood it on itself: every Datarim release is shipped through the Datarim pipeline. Multi-runtime support: Claude Code is primary, Codex CLI achieves parity through the coworker rtk shim, and Cursor reaches parity through its native beforeShellExecution hook (rtk hook cursor) — all three runtimes share the same RTK token economy; see the canonical runtime support matrix (datarim.club/en/multi-agent) for details. Open-source, MIT, with full documentation at datarim.club.
