Explores using asynchronous coding agents (Claude Code, Codex, Jules) for code research tasks. The approach involves posing research questions to agents that work independently in dedicated GitHub repositories with full network access, then return with pull requests containing experimental code and findings. Examples include benchmarking Python Markdown libraries, compiling C extensions for WebAssembly, and training text classification models. The pattern enables developers to run multiple research experiments daily with minimal time investment, though results should be treated as AI-generated content requiring verification.
