Spec-Driven Develop
A Markdown-only workflow plugin for AI coding agents that turns large software changes into a spec-driven loop of project analysis, task decomposition, GitHub issue and PR tracking, and adaptive control.
Spec-Driven Develop is an open-source, platform-agnostic workflow for AI coding agents such as Claude Code, Codex, OpenCode and Cursor, built entirely from Markdown skills and small helper scripts with no SDK or third-party runtime dependency.
It ships three complementary skills: Spec-Driven Develop itself automates a full pipeline for large, complex tasks, deep project analysis, phased task decomposition, document-driven progress tracking and execution within a single session; Deep Discuss is a structured multi-phase workflow for problem analysis, brainstorming and solution design; and Review SPD is a findings-first code review workflow for uncommitted changes, date-range commits, and branch or pull-request diffs, focused on bugs and regressions.
The design is inspired by Qian Xuesen's engineering cybernetics and targets developers using AI coding agents for migrations, rewrites, refactors, architecture changes and complex implementation plans.
