Stanford’s Fall 2025 semester offers a course CS146S “Modern Software Developer,” which teaches how to write software together with coding Agents. All 8 weeks of assignments are publicly available on GitHub.

Each week covers one theme, starting with prompt engineering techniques, then adding features to an existing small app, and writing your own MCP service to connect external APIs to the model.

Later, you’ll use Claude Code to build at least two automated workflows, use Semgrep to scan and fix at least 3 security vulnerabilities, and in the final week, implement the same app using 3 different tech stacks.

I really liked the seventh week’s assignment—each task involves giving the AI just one prompt to complete the writing, then reviewing it line by line yourself, and finally comparing your review comments with the results of the AI’s own review.

Many assignments come with starter projects and tests; the first week even uses Ollama to run models locally. If you don’t have a chance to take a class like this, working through the 8 weeks of assignments on your own can fill in a lot of gaps.
