Task Decomposition & Execution with Codex

Master THE CORE SKILL of SDD: breaking complex features into atomic, AI-digestible tasks. Learn decomposition principles (1-3 files, clear criteria, explicit dependencies), practice on progressively complex features, execute tasks with Codex using test-first workflow. Experience common failure modes (scope creep, wrong dependencies, missing handoffs) and learn correction patterns.

I love that it's personalized. When I'm stuck, I don't have to hope my Google searches come out successful. The AI mentor Cosmo knows exactly what I need.

It's an amazing product and exceeded my expectations, helping me prepare for my job interviews. Hands-on learning requires you to actually know what you are doing.

Alex Bush

Full Stack Engineer

I'm really impressed by the AI tutor Cosmo's feedback about my code. It's honestly kind of insane to me that it's so targeted and specific.

Abbey Helterbran

Tech consultant

I tried Leetcode but it was too disorganized. CodeSignal covers all the topics I'm interested in and is way more structured.
