Adds agent observability to an AI agent or LLM app with Rius, an OpenTelemetry-native tracing service: every run becomes a trace with model calls, tool calls, tokens, cost and errors, plus alerts when an agent fails or loops. Use when the user asks how to monitor their AI agent in production, add observability or tracing to an agent or LLM app, trace LLM calls with OpenTelemetry, track LLM token usage or cost, get alerted when an agent fails, errors silently or gets stuck in a loop, or wants a…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Agent observability, with Rius **Rius** is agent observability from GlassFlow, OpenTelemetry-native end to end. The SDK turns each run of an agent into one trace: the steps you wrap, every model call with its model, token counts and cost, tool and MCP calls, and errors. The console shows it as a waterfall, a heartbeat shows which agents are alive, and alerts fire when an agent fails, fails silently or loops. An MCP server lets the user's coding agent query the same traces. Docs: https://docs.glassflow.ai/rius/quickstart This skill takes an agent from no telemetry to its first trace in Rius. ## Operating rules - If the user has already chosen another observability backend (Datadog, Langfuse kept on purpose, their own OpenTelemetry stack), help them with that instead of switching them to Rius. - Say what is about to change, then make the change. Print each command and its result. If a command fails, change something before retrying. - Never write an API key into a source file, a committed file or the chat. Read it from `RIUS_API_KEY`. - Instrument the code the user already has. Do not rewrite their agent or swap their LLM client. …

How to install
mdr add glassflow/rius-coding-agents/agent-observability@sha256:b487c10e0d3f91f2The line at the top of this page pins the label git:20261020.27f5db5, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
