DeepNexus Code

DeepNexus Code is a minimalist AI coding assistant for the terminal. It is a single Python file with no third-party dependencies, works with any OpenAI-compatible endpoint, and is small enough to read in an afternoon and extend however you like.

Install

Requires Python 3.10 – 3.13.

curl -fsSL http://localhost:3000/install/code.sh | bash

The script downloads dncode into ~/.local/bin (override with DNCODE_DIR) and makes it executable. Make sure that directory is on your PATH.

Configure

export DEEPNEXUS_API_KEY="sk-dn-..."

Optional settings:

Variable	Default	Description
`DNCODE_MODEL`	`deepseek-v4-pro`	Model to use
`DNCODE_BASE_URL`	`http://localhost:3000/v1`	Any OpenAI-compatible base URL, e.g. `http://localhost:11434/v1` for Ollama
`DNCODE_API_KEY`	`$DEEPNEXUS_API_KEY`	API key for the base URL

Run

cd your-project
dncode

Tools

Tool	Description
`read_file`	Read a file, optionally a line range
`write_file`	Create or overwrite a file
`edit_file`	Replace an exact snippet in a file
`list_files`	List files, respecting `.gitignore`-style ignores
`search`	Search file contents with a regular expression
`run_shell`	Run a shell command in the project (asks for confirmation)

Every file change and shell command is shown before it runs. Shell commands require confirmation unless you start with --yes.

Commands

Command	Description
`/model <id>`	Switch model mid-session
`/save [name]` / `/load [name]`	Save or resume a session from `~/.dncode/sessions`
`/changes`	List files modified in this session

Long conversations are compacted automatically before they exceed the model's context window.
