Building complex, multi-step AI processes directly with code generators creates a black box that is difficult to debug. Instead, prototype and validate the workflow step-by-step using a visual tool like N8N first. This isolates failure points and makes the entire system more manageable.

AI interactions often involve multiple steps (e.g., user prompt, tool calls, retrieval). When an error occurs, the entire chain can fail. The most efficient debugging heuristic is to analyze the sequence and stop at the very first mistake. Focusing on this "most upstream problem" addresses the root cause, as downstream failures are merely symptoms.
Vercel's Pranati Perry argues that even with no-code AI tools, having some coding knowledge is a superpower. It provides the vocabulary to guide the LLM, give constructive criticism during debugging, and avoid building on a 'house of cards,' leading to better, more stable results.
LLMs often get stuck or pursue incorrect paths on complex tasks. "Plan mode" forces Claude Code to present its step-by-step checklist for your approval before it starts editing files. This allows you to correct its logic and assumptions upfront, ensuring the final output aligns with your intent and saving time.
High productivity isn't about using AI for everything. It's a disciplined workflow: breaking a task into sub-problems, using an LLM for high-leverage parts like scaffolding and tests, and reserving human focus for the core implementation. This avoids the sunk cost of forcing AI on unsuitable tasks.
Many AI tools expose the model's reasoning before generating an answer. Reading this internal monologue is a powerful debugging technique. It reveals how the AI is interpreting your instructions, allowing you to quickly identify misunderstandings and improve the clarity of your prompts for better results.
Prototyping and even shipping complex AI applications is now possible without writing code. By combining a no-code front-end (Lovable), a workflow automation back-end (N8N), and LLM APIs, non-technical builders can create functional AI products quickly.
To ensure comprehension of AI-generated code, developer Terry Lynn created a "rubber duck" rule in his AI tool. This prompts the AI to explain code sections and even create pop quizzes about specific functions. This turns the development process into an active learning tool, ensuring he deeply understands the code he's shipping.
AI code generation tools can fail to fix visual bugs like text clipping or improper spacing, even with direct prompts. These tools are powerful assistants for rapid development, but users must be prepared to dive into the generated code to manually fix issues the AI cannot resolve on its own.
The panel suggests a best practice for AI prototyping tools: focus on pinpointed interactions or small, specific user flows. Once a prototype grows to encompass the entire product, it's more efficient to move directly into the codebase, as you're past the point of exploration.
For complex, one-time tasks like a code migration, don't just ask AI to write a script. Instead, have it build a disposable tool—a "jig" or "command center”—that visualizes the process and guides you through each step. This provides more control and understanding than a black-box script.
