# Slitherin by Pessimistic.io
[](https://blog.pessimistic.io/)
[](https://pessimistic.io/)
[](mailto:[email protected])
**Welcome!** We are the [pessimistic.io](https://pessimistic.io/) team, and in recent months we have been actively developing our [own **Slither detectors**](https://github.com/pessimistic-io/slitherin/tree/develop/slitherin/detectors) to help with code review and audit process. This repository contains everything you may require to work with them!
We increased the sensitivity of our detectors since they are *quite straightforward* and not written in the "original style." As a result, they produce FPs ([False Positives](https://en.wikipedia.org/wiki/False_positives_and_false_negatives)) more frequently than original ones. So that, our detectors are a kind of automation of the checks implemented in the checklist, their main purpose is to look for issues and assist the code auditor.
Please let us know if you have discovered an [issue/bug/vulnerability](https://telegra.ph/BountyCTF-Platforms-Web3-04-19) via our custom Slither detectors. You may contact us via opening a [PR/Issue](https://github.com/pessimistic-io/slitherin/issues) or [directly](mailto:[email protected]), whichever is more convenient for you. If you have any further questions or suggestions, please [join our Discord Server](https://discord.gg/vPxkR8B9p7) or [Telegram chat](https://t.me/+G96ejJ7Pmgk1NDZi)! We hope to see you there, and we intend to support the community and its initiatives!

## Installation Process
### Using Git
To install Pessimistic Detectors:
1. Install the [original Slither](https://github.com/crytic/slither#how-to-install);
2. Clone our repository;
3. Run the following command in our repository folder to add new detectors to Slither:
```bash
python3 setup.py develop
```
> Keep in mind that you don't have to reinstall the plugin after changes in the repository!
4. Dependencies must be installed in order to test the detectors on our test contracts:
```bash
npm install
```
### Using Pip
1. Install the [original Slither](https://github.com/crytic/slither#how-to-install);
2. Install the pip [package](https://pypi.org/project/slitherin/):
```bash
pip install slitherin
```
## Usage
### Slitherin-cli (Recommended)
Use Slitherin-cli to run detectors on a Hardhat/Foundry/Dapp/Brownie application. You have the following options:
* Run ONLY Slitherin detectors:
```bash
slitherin . --pess
```
* Run ONLY Slither detectors:
```bash
slitherin . --slither
```
* Run Slither detectors, then Slitherin detectors:
```bash
slitherin . --separated
```
* Run Arbitrum-specific Slitherin detectors:
```bash
slitherin . --arbitrum
```
> Keep in mind that Slitherin-cli supports all Slither run options.
### Slither
Slitherin detectors are included into original Slither after the installation. You can use Slither [as usual](https://github.com/crytic/slither#usage).
