Plugins

A Klyrek plugin is a Python class with one method:

from klyrek_core.plugins import Plugin, register_plugin

@register_plugin
class GraphQLFinder(Plugin):
    name = "graphql"
    category = "tech-fingerprint"

    def run(self, response):
        if "/graphql" in str(response.url):
            return "graphql-api"

Plugin is an abstract base class with two class variables (name, category) and one abstract method (run). @register_plugin adds the class to Klyrek's plugin registry so the pipeline can discover and invoke it alongside the built-in packages.

There's no separate plugin SDK to learn beyond this — if you can write a function that takes an httpx.Response and returns something, you can write a plugin. Ship it privately for a client-specific fingerprint, or contribute it back for a signature that's broadly useful.

See klyrek-core for the full Plugin/register_plugin reference.
