According to @nummanali, GPT-5.2 Codex Extra High was able to automate over two hours of tech debt cleanup, specifically removing all instances of 'any' and type casting in code, updating lint and type configurations to prevent future issues, and ensuring all quality gates such as lint:fix, typecheck, and test passed (source: https://x.com/nummanali/status/2009613073276178546). This demonstrates a significant leap in AI-powered coding tools, enabling software teams to streamline maintenance, improve code quality, and reduce manual engineering hours. The business impact includes faster release cycles, reduced technical debt accumulation, and increased developer productivity, making AI code assistants a compelling investment for enterprises (source: @gdb, https://twitter.com/gdb/status/2009698169396048062).
