llm-observability SKILL.md skillA
llm-observability from nahid-sparktales/agent-dispatcher is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

See what an agent actually did — one trace per run with nested model, tool and retrieval spans, token and latency accounted per step, and failures clustered by mechanism instead of read one at a time. Use when an agent misbehaves in ways you cannot reproduce, when cost or latency is unexplained, when "it sometimes fails" is the whole bug report, or before writing evals when you do not yet know which failures exist. Not for judging whether an output is correct (agent-evals), and not 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
# LLM observability An agent run is a tree of decisions, most of which nobody saw. Without a trace you are left re-running the prompt and hoping the failure happens again while you watch. ## When this fires A failure that will not reproduce, a cost or latency number nobody can account for, a "sometimes" bug, or the start of eval work where the failure modes are still unknown. It does not fire for a single deterministic call whose input and output you already hold. ## Procedure 1. **State the question first.** "Why did run X do Y", "where is the cost going", "which failures share a cause". Instrumentation added without a question becomes expensive noise nobody reads. 2. **One trace per run, nested by causality.** The run is the root; each model call, tool call, retrieval and retry is a child span in the place it actually happened. A flat log of lines loses the one thing you need — which step caused which. 3. **Record per span what cannot be reconstructed afterwards**: model id, prompt or system-prompt version, sampling parameters, input and output token counts, stop reason, tool name and …

How to install
mdr add nahid-sparktales/agent-dispatcher/llm-observability@sha256:459396d48a7ea26aThe line at the top of this page pins the label git:20260919.a0d4f55, 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.
