About huginn
Huginn is an open source system for building agents that perform automated tasks online, written in Ruby and released under the MIT license. Its agents read the web, watch for events, and take actions on the user's behalf. Internally, agents create and consume events that propagate along a directed graph, which means one agent's output becomes another agent's input and a chain of small steps can be composed into a larger workflow. The project lives in the Ruby ecosystem and is distributed as an official Docker image or installed locally from a forked repository.

About opentelemetry-go
OpenTelemetry Go is the Go implementation of OpenTelemetry, the vendor neutral observability framework. It provides a set of APIs that let Go programs directly measure the performance and behavior of their own software, then send the resulting telemetry to observability platforms. The project lives in the Go ecosystem and is distributed as the module go.opentelemetry.io/otel , published on pkg.go.dev and licensed under Apache 2.0. It is a long running, actively maintained repository, roughly seven years old, with a large contributor base and a steady release cadence.
