Adding a new detector

Slither's plugin architecture lets you integrate new detectors that run from the command line.

The skeleton for a detector is:

from slither.detectors.abstract_detector import AbstractDetector, DetectorClassification


class Skeloton(AbstractDetector):
    """
    Documentation
    """

    ARGUMENT = 'mydetector' # slither will launch the detector with slither.py --mydetector
    HELP = 'Help printed by slither'
    CLASSIFICATION = DetectorClassification.HIGH

    def detect(self):
        return []

• ARGUMENT lets you run the detector from the command line
• HELP is the information printed from the command line
• CLASSIFICATION indicates your confidence in the impact of the issue. Allowed values are:
  • DetectorClassification.LOW: printed in green
  • DetectorClassification.MEDIUM: printed in yellow
  • DetectorClassification.HIGH: printed in red

detect() needs to return a list of findings. To facilitate the automation of Slither, a finding is a dictionary containing a vuln key associated with the vulnerability name and additional information according to the vulnerability itself.

An AbstractDetector object has the slither attribute, which returns the current Slither object, and the log(str) function to print the result.

For example, backdoor.py will detect any function with backdoor in its name.

You will find a skeleton example to integrate your detector into slither in slither/plugin_example.
