inwo. Ralph is a brutally simple technique — loop the same prompt into a coding agent until the task is done. What it is, how the two main implementations (Anthropic's ralph-wiggum plugin and snarktank/ralph) actually differ, the anecdotal numbers behind the hype, and an honest critical review of where it breaks.
OpenSpec is an open-source, lightweight spec-driven-development tool that adds a spec layer so humans and AI agree on what to build before code. What it is, how the propose → apply → archive workflow and delta specs work, how it compares to Spec Kit and Kiro, and its honest tradeoffs.
Spec Kitty is an open-source Python CLI that turns product intent into a repo-native, spec-driven workflow — spec, plan, tasks, review, accept, merge — with isolated git worktrees for parallel agents, a local kanban dashboard, and governance gates. What it is, how it works, use cases, and where it fits versus lighter tools.
Two open-source takes on spec-driven development for AI coding agents — Spec Kitty's governed software factory versus OpenSpec's lightweight spec layer. The real differences, pros and cons, examples, and when to reach for each.
