# llm-debug

### A Minimal Python Library to debug with LLMs

Ldbg enables to use natural-language prompts while debugging. Prompts are augmented with your current stack, variables, and source context.
It is like [ShellGPT](https://github.com/TheR1D/shell_gpt) but for pdb, ipdb, Jupyter, the VS Code Debug Console, etc.

DO NOT USE THIS LIBRARY

> “AI everywhere is rocket engines on a skateboard: a thrill that ends in wreckage. The planet pays in energy and emissions, and we pay in something subtler — the slow atrophy of our own intelligence, left idle while the machines do the heavy lifting.” ChatGPT

Here is [CJ Reynolds](https://www.youtube.com/watch?v=0ZUkQF6boNg) point of view:

> I used to enjoy programming. Now, my days are typically spent going back and forth with an LLM and pretty often yelling at it… And part of enjoying programming for me was enjoying the little wins, right? You would work really hard to make something… or to figure something out. And once you figured it out, you'd have that little win. You'd get that dopamine hit and you'd feel good about yourself and you could keep going. I don't get that when I'm using LLMs to write code. Once it's figured something out, I don't feel like I did any work to get there. And then I'm just mad that it's doing the wrong thing. And then we go through this back and forth cycle and it's not fun.

## Features

- 🐍 Generate Python debug commands from natural-language instructions.
- 🔍 Context-aware: prompt auto-includes call stack, local/global variable previews, current function source, and nearby code.
- 🤖 Supports multiple LLM providers: OpenAI, Anthropic, DeepSeek, Groq, Together AI, OpenRouter, Ollama

**NOTE**: In VS Code, you enter the function in the Debug Console, and get the output in the terminal ; so put both tabs (Debug Console and Terminal) side to side.

## Installation

`uv add ldbg`, `pixi add --pypi ldbg` or `pip install ldbg`

## Quick Start

### Example natural-language prompts

- "Describe my numpy arrays"
- "plot my_data['b'] as a histogram"
- "give me an example pandas dataframe about employees"
- "generate a 3x12x16 example Pillow image from a numpy array"
- "convert this Pillow image to grayscale"
- "open this 'image.ome.tiff' with bioio"

### Example Session

```python

>>> unknown_data = np.arange(9)
>>> example_dict = {"a": 1, "b": [1, 2, 3]}
>>> example_numbers = list(range(10))
>>> import ldbg
>>> ldbg.gc("describe unknown_data")
The model "gpt-5-mini-2025-08-07" says:

    unknown_data is an numpy array which can be described with the following pandas code:
    
    ```
    pandas.DataFrame(unknown_data).describe()
    ```

    Note: you can use numpy.set_printoptions (or a library like numpyprint) to pretty print your array:
    
    ```
    with np.printoptions(precision=2, suppress=True, threshold=5):
        unknown_data
    ```

Would you like to execute the following code block:
    pandas.DataFrame(unknown_data).describe()
(y/n)
```

User enters y:
```
            0
count  9.000000
mean   4.000000
std    2.738613
min    0.000000
25%    2.000000
50%    4.000000
75%    6.000000
max    8.000000



Would you like to execute the following code block:
    with np.printoptions(precision=2, suppress=True, threshold=5):
        unknown_data
(y/n)
```

User enters n and continues:

```python
>>> ldbg.gc("plot example_numbers as a bar chart")
The model "gpt-5-mini-2025-08-07" says:

    ```
    import matplotlib.pyplot as plt
    plt.bar(range(len(numbers)), numbers)
    plt.show()
    ```

Would you like to execute the following code block:
...
```

## Configuration

By default, llm-debug uses the OpenAI client. So it reads the [OPENAI_API_KEY environment variable](https://platform.openai.com/docs/quickstart).

### Supported Providers

You can use any of the following LLM providers by setting the `LDBG_API` environment variable:

#### OpenAI (default)
```bash
export OPENAI_API_KEY="your_api_key_here"
```

#### DeepSeek
```bash
export LDBG_API="deepseek"
export DEEPSEEK_API_KEY="your_api_key_here"
```

#### Anthropic (Claude)
```bash
export LDBG_API="anthropic"
export ANTHROPIC_API_KEY="your_api_key_here"
```

#### Groq
```bash
export LDBG_API="groq"
export GROQ_API_KEY="your_api_key_here"
```

#### OpenRouter
```bash
export LDBG_API="openrouter"
export OPENROUTER_API_KEY="your_api_key_here"
```

#### Together AI
```bash
export LDBG_API="together"
export TOGETHER_API_KEY="your_api_key_here"
```

#### Ollama (local)
```bash
export LDBG_API="ollama"
# No API key required for local Ollama installations
```

### Custom Model

By default, each provider uses its recommended model. You can override this by passing the `model` parameter to `ldbg.gc()`:

```python
import ldbg
ldbg.gc("describe my_data", model="gpt-4-turbo")
ldbg.gc("describe my_data", model="deepseek-coder")
ldbg.gc("describe my_data", model="claude-3-opus-20240229")
```
