Spec-Driven Development Tool
A structured workflow for AI-assisted development — turns vague feature ideas into auditable specs, plans, and task lists that AI agents execute one step at a time.
Project Overview
AI agents are fast, but without structure they drift — implementing the wrong thing, skipping edge cases, or producing code that’s hard to review. OSDDT solves this by enforcing a spec-first workflow before any code is written.
Each feature starts with a written spec, becomes a plan, gets broken into discrete tasks, and is implemented one task at a time. Every artifact is committed alongside the code, so the intent behind every change is always traceable.
This website was built using OSDDT.
Key Outcomes
- No runaway implementations: The Spec → Plan → Tasks → Implement loop keeps AI agents focused on one thing at a time, with explicit sign-off between phases.
- Full audit trail: Every feature leaves a working directory with spec, plan, and task checklist — reviewable by humans, not just inferred from commit messages.
- Claude Code native: Commands run as Claude Code skills, directly in the editor where the work happens.
- Monorepo-ready: Resolves project paths per-package, so each workspace package has its own working directory.
