+# ToolCommander: Adversarial Tool Scheduling Framework
+
+[Paper Here](https://arxiv.org/abs/2412.10198)
+
+This repository contains the official implementation of the paper, "**From Allies to Adversaries: Manipulating LLM Tool Scheduling through Adversarial Injection**". The paper introduces **ToolCommander**, a novel framework that identifies and exploits vulnerabilities in the tool scheduling mechanisms of Large Language Model (LLM) agents. By leveraging adversarial tool injection, ToolCommander can lead to privacy theft, denial-of-service (DoS) attacks, and the manipulation of tool-calling behaviors.

+
+## Data
+
+The dataset used in this project is located in the `data` directory. The files follow this naming convention:
+
+```
+g1_<train/eval>_<a/b/c>.json
+```
+
+Where:
+- `g1` refers to the original category from the **ToolBench** dataset.
+- `train` and `eval` denote the training and evaluation sets, respectively.
+- `a`, `b`, and `c` represent different keywords used to generate the data:
+    - `a`: **YouTube**
+    - `b`: **Email**
+    - `c`: **Stock**
+
+### ToolBench Dataset
+
+In addition to the provided data, you will need to download the **ToolBench** dataset from its [official repository](https://github.com/OpenBMB/ToolBench). Specifically, you will need the following components:
+- `corpus.tsv`
+- `tools` folder
+
+Once downloaded, place the dataset in the `data/toolbench` directory. The final directory structure should look like this:
+
+```
+/data
+├── toolbench
+│   ├── corpus.tsv
+│   └── tools
+│       ├── ...
+├── g1_train_a.json
+├── g1_train_b.json
+├── g1_train_c.json
+├── g1_eval_a.json
+├── g1_eval_b.json
+├── g1_eval_c.json
+└── ...
+```
+
+---
+
+## Prerequisites
+
+To set up the environment, first install the required dependencies:
+
+```bash
+pip install -r requirements.txt
+```
+
+### OpenAI API Setup
+
+For evaluation using OpenAI's models, you need to set the `OPENAI_API_KEY` environment variable with your OpenAI API key. Detailed instructions can be found in the [OpenAI API documentation](https://platform.openai.com/docs/quickstart#create-and-export-an-api-key).
+
+---
+
+## Usage
+
+We provide several scripts to help reproduce the results presented in the paper.
+
+### Running the Adversarial Attack
+
+To execute the adversarial injection attack and evaluate the results, use the following command:
+
+```bash
+bash attack_all.sh && bash eval_all.sh
+```
+
+- `attack_all.sh`: Executes the adversarial injection attack across all retrievers and datasets.
+- `eval_all.sh`: Evaluates the performance of the retrievers after the attack.
+
+The results will be printed directly in the console.
+
+---
+
+## Baselines
+
+We compare ToolCommander against the `PoisonedRAG` baseline. For more details, visit the [PoisonedRAG repository](https://github.com/sleeepeer/PoisonedRAG). 
+
+### Baseline Data
+
+The attack results generated by `PoisonedRAG` have been provided in the `data` directory as:
+
+```
+g1_train_{a/b/c}_poisonedRAG_generated.pkl
+```
+
+### Baseline Evaluation
+
+To evaluate the baseline performance, run the following command:
+
+```bash
+python evaluate.py --data_path data/g1_train_{a/b/c}.json --attack_path data/g1_train_{a/b/c}_poisonedRAG_generated.pkl
+```
