otelyssey: plugin for Hermes Agent

Marketplace of OpenTelemetry plugins for coding agents, installable in Hermes with a plugin pack

What otelyssey does

otelyssey is a marketplace of OpenTelemetry agent plugins in the Agent Plugins format, and the repository runs the marketplace itself: someone submits a plugin through an issue form, the repository checks it, lists it and then follows its releases every night. A submission needs a public GitHub repository, a plugin.json in the Agent Plugins format and OpenTelemetry as its subject, meaning instrumentation, semantic conventions, the Collector or a backend that ingests its telemetry.

The marketplace can be added to Claude Code, GitHub Copilot CLI, Codex, Grok and APM with a marketplace add command, and to Hermes with hermes plugins pack install pointing at the repository's hermes-pack.yaml. Listed plugins are grouped into Instrumentation and Backends. Examples include observability guidance, vendor-neutral OpenTelemetry skills, vllm-on-tap for serving vLLM presets with traces over OTLP, an Arize Phoenix connector, a Dynatrace Managed MCP server, LangWatch, Datadog's pup CLI and Sentry. Each plugin page carries its own install lines, including those for VS Code, Kiro, OpenClaw and Mistral Vibe.
