1jehuang/jcode ? reverse-engineered prompt

Build me a lightning fast terminal coding agent called jcode.

It runs in the terminal with a clean responsive TUI, starts in under 20 milliseconds, and stays under 30 MB of RAM for a single session even when talking to Claude or OpenAI. You can launch many sessions at once without the machine melting.

The agent should feel like a true coding partner that remembers context across days, handles multi step projects, and lets you customize its skills and workflows however you want. Think of it as a lightweight harness that raises the skill ceiling instead of the usual heavy desktop apps that eat hundreds of megabytes.

Make the whole thing in Rust, keep it snappy, and give it that buttery smooth feel you see in the memory demo videos. Look up current best practices for terminal UIs and LLM tool calling if you need to.
