# Command Code

> Command Code is a frontier coding agent that builds software and continuously learns your coding taste. It ships full-stack projects, features, fixes bugs, writes tests, and refactors — all while learning how you write code. Powered by the meta neuro-symbolic AI model `taste-1` with continuous reinforcement learning.

Install and run:

```
npm i -g command-code
cd your-project && cmd
```

Important notes:

- Command Code is a CLI-first terminal agent — run `cmd` in any project directory to start an interactive session
- **Taste** is the core differentiator: a personalized model that learns your coding style, patterns, and preferences automatically from every accept, reject, and edit
- Taste profiles are stored locally in `.commandcode/taste/` and can be shared via `npx taste push/pull`
- Custom instructions are set via `AGENTS.md` files (project-level or user-level at `~/.commandcode/AGENTS.md`)
- Agent Skills (`.commandcode/skills/`) extend Command Code with specialized knowledge and workflows following the [Agent Skills open standard](https://agentskills.io)
- MCP (Model Context Protocol) servers connect Command Code to external tools and services (databases, APIs, GitHub, Notion, etc.)
- Permission modes: **Standard** (confirmation required), **Plan** (read-only exploration), **Auto-Accept** (no confirmation). Toggle with `Shift+Tab`
- Checkpoints are created automatically before file modifications; rewind with `Esc Esc` or `/rewind`
