rubber-ducky 1.2.2

Quick CLI do-it-all tool. Use natural language to spit out bash commands

Rubber Ducky

Rubber Ducky is an inline terminal companion that turns natural language prompts into runnable shell commands. Paste multi-line context, get a suggested command, and run it without leaving your terminal.

Quick Start

Action	Command
Install globally	uv tool install rubber-ducky
Run once	uvx rubber-ducky -- --help
Local install	uv pip install rubber-ducky

Requirements:

• Ollama running locally
• Model available via Ollama (default: qwen3-coder:480b-cloud, install with ollama pull qwen3-coder:480b-cloud)

Usage

ducky                 # interactive inline session
ducky --directory src  # preload code from a directory
ducky --model llama3   # use a different Ollama model

Both ducky and rubber-ducky executables map to the same CLI, so uvx rubber-ducky -- <args> works as well.

Inline Session (default)

Launching ducky with no arguments opens the inline interface:

• Enter submits; Ctrl+J inserts a newline (helpful when crafting multi-line prompts). Hitting Enter on an empty prompt reruns the latest suggested command; if none exists yet, it explains the most recent shell output.
• Ctrl+R re-runs the last suggested command.
• Prefix any line with ! (e.g., !ls -la) to run a shell command immediately.
• Arrow keys browse prompt history, backed by ~/.ducky/prompt_history.
• Every prompt, assistant response, and executed command is logged to ~/.ducky/conversation.log.
• Press Ctrl+D on an empty line to exit.
• Non-interactive runs such as cat prompt.txt | ducky print one response (and suggested command) before exiting; if a TTY is available you'll be asked whether to run the suggested command immediately.
• If prompt_toolkit is unavailable in your environment, Rubber Ducky falls back to a basic input loop (no history or shortcuts); install prompt-toolkit>=3.0.48 to unlock the richer UI.

ducky --directory <path> streams the contents of the provided directory to the assistant the next time you submit a prompt (the directory is read once at startup).

Development (uv)

uv sync
uv run ducky --help

uv sync creates a virtual environment and installs dependencies defined in pyproject.toml / uv.lock.

Telemetry & Storage

Rubber Ducky stores:

• ~/.ducky/prompt_history: readline-compatible history file.
• ~/.ducky/conversation.log: JSON lines with timestamps for prompts, assistant messages, and shell executions.

No other telemetry is collected; delete the directory if you want a fresh slate.
