Instrument LLM agents with traces, metrics, and replay. Use when an agent in production is silently failing, regressing, drifting, or burning tokens. Selects LangSmith / Langfuse / Phoenix, defines node-level spans, attaches evals to traces, and enables session replay.
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 ## Overview Production agents fail differently than services: bad tool calls, hallucinated arguments, runaway loops, silent quality regression. This skill picks an observability backend, instruments node-level spans, attaches evals to traces, and sets up replay — so failures are *observable*, not just guessed at. ## When to use - Agent works in dev, breaks in prod with no logs that explain why - Need to compare prompt/model changes against a baseline (eval-in-trace) - Token/latency cost is growing and you don't know which node is the culprit - A user reports a bad answer and you need to *replay* the exact session - Multiple agents/subagents — you need a single trace tree, not interleaved logs ## Platform selection | Backend | Pick when | Hosting | |---------|-----------|---------| | LangSmith | LangChain/LangGraph stack, want managed | SaaS | | Langfuse | Open-source, self-host required, multi-framework | SaaS or self-host | | Arize Phoenix | OTel-native, embed/eval drift, OSS-first | Local or self-host | Default: **Langfuse** when you need self-host, **LangSmith** when you're already on LangGraph, **Phoenix** when OTel is mandated. …

How to install
mdr add akillness/jeo-skills/agent-observability@sha256:5d20fb8cf882f342The line at the top of this page pins the label git:20260919.9f2a908, 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.
