Show HN: Vim-like, hyper-efficient, LLM power tool – 20-80k tokens not 350k+

I built a focused TUI tool for efficient parallelized tasks, early independent testers expressed 90%+ API savings and more direct results. This is accomplished by user smaller context windows, hybrid client-side compaction, tool compaction, and system nudges (to avoid polluting the base prompts).

My Shell features:

- Vim-inspired keybindings, your keys never have to leave the keyboard (some mouse control supported as well)

- Custom Markdown, LaTeX, and Mermaid rendering support

- On-demand subagents with LLM-directed context handoff

- Thread pooling, client-side compaction, tool compaction

- Supports Powershell without a degraded experience; also support VGA/VESA mode, run even when GPU drivers break!

- Single bundle, no external packages required

It’s opinionated, terminal-first, Vim-inspired; if that’s not for you, I have a web chat and a desktop app coming soon
