AI coding agents work better when they have clear instructions. OpenSpec is a tool-agnostic framework for new and existing projects that helps teams write structured, machine-readable specifications that guide AI agents through the software development lifecycle.
This OpenSpec course introduces Spec-Driven Development (SDD) using the OpenSpec framework, where executable specifications (not chat prompts) are the source of truth for what gets built.
Learners master how to write proposals, specifications, and technical designs that drive implementation with AI agents, while managing the lifecycle of specifications from proposal to archive. Through hands-on labs, learners apply the spec-first philosophy to real-world development scenarios, ensuring their AI-assisted projects are grounded in clear, actionable specifications.
Skills Gained
By the end of this course, participants will be able to:
- Apply the spec-first philosophy to AI-assisted development
- Initialize and configure OpenSpec projects and profiles
- Write proposals, specifications, and designs that guide AI agents
- Decompose specs into tasks and drive implementation with agents
- Manage specifications from proposal through archive
Who Can Benefit
- Senior Software Developers
- AI Engineers & Architects
- Technical Leads
Prerequisites
- Practical Python or JavaScript/TypeScript experience
- Experience with AI Coding Agents (e.g., AIC-1102 Foundations of AI Coding Agents with GitHub Copilot or equivalent)

Reviews
This is my second course with ExitCertified. This course exceeded my expectations. The teacher was great and the class was fun.
Courseware was effective but would like to have some PDF material on BPML and XPATH
It is very good and very simple instructions. almost to much hand holding.
ExitCertified provided us with a great opportunity to learn more about React and in easy to follow way.
my experince was great from the day i regetered to the actuall day of the class.
