1. Interpreted languages dominate for rapid iteration
"1. it's built for async 2. runs everywhere 3. interpreted, making it fast to iterate on ... decent performance most popular language, llms are decent at writing it" â m_ke
2. Nodeâcentric harnesses raise CPU/memory concerns
"My laptop is sweating when I got 5+ claude code sessions running." â eglintondust
3. Pluginâbased, traceable harnesses enable modular extension
"Everything the model sees is recorded in an appendâonly session log: system prompts, reasoning, tool calls and results, subagent scheduling, and every context injection." â kamranjon
