A bash and zsh shell with LLM prompting built in
Start any line with a capital letter to send it to the AI as a prompt, while normal lowercase commands behave exactly as before.
The model receives your recent commands and their output, so follow-up questions like 'why did that fail?' get grounded answers.
Copilot-style command suggestions appear in the shell and can be applied with Tab, informed by your recent history.
Trigger an autonomous loop with ! to have the model propose commands toward a goal, or !! to let it run them without confirmation.
The coding agent that learns your coding taste
A continuous reinforcement-learning layer that turns every accept, reject and manual edit into a signal, then converts recurring patterns into reusable project-level skills.
Automatically repairs malformed tool calls so weaker open-weight models can complete agent loops reliably, levelling them up toward frontier performance.
Use an interactive CLI for pairing, a headless flag for scripting, or a background sandbox agent for longer autonomous jobs.
Custom /agents and persistent /memory carry project context across sessions so you stop re-explaining your codebase and conventions.
