Fast Code Generation Is Easy. Safe System-level Change Is Not.
AI coding tools are good at writing local diffs, but they still miss repo-wide truth. In large TypeScript and JavaScript codebases, that means dead exports, duplicated logic, accidental boundary violations, and complexity creep after every “small” AI refactor. In this talk, I’ll show a practical workflow for working with large codebases using AI: let the agent generate, run deterministic codebase analysis, feed the findings back via CLI/MCP, and gate drift in CI before it lands. Fallow is the case study, but the workflow applies beyond one tool.
