# Cognitive Debt and Walkthroughs

When engineers allow agents to produce code without understanding how the internal mechanics function, they accumulate **cognitive debt**. Over time, the codebase turns into an opaque black box that paralyzes future design decisions.

## Remedies
- **Linear Walkthroughs:** Directing an agent (via tools like `showboat`) to generate an ordered, step-by-step breakdown of newly created files, executing tools to embed real code snippets rather than copying text manually.
- **Interactive & Animated Explanations:** When an algorithm is complex (e.g., Archimedean spiral word-cloud layouts or AST parsing), prompting the agent to build an interactive HTML/JS widget with step-through sliders and visual rendering to build intuitive comprehension.
- **Editorial Diagramming:** Using structured, accessible visual architectures ([editorial diagrams and visual explanations](/wiki/editorial-diagrams-and-visual-explanations)) authored by [cathryn lavery](/wiki/cathryn-lavery) to visualize flows, decision trees, and system state with strict density and signal discipline.
- **Paying Down the Debt:** Understanding the code is a prerequisite for maintaining it; using agentic explanations turns opaque generated code into human-comprehensible assets.
