  Datadog Labs · datadog-labs/agent-skills 176

  Run an iterative code-improvement hill-climb against real Datadog LLM-Obs data, locally, with Claude Code as the agent. Establishes a baseline eval, makes one focused change, re-scores with the same harness, keeps the change if it improves the score in the goal's direction (labeling within-noise gains tentative), and repeats. Use when the user says "run an auto experiment", "hill-climb this code", "iteratively improve X and measure the delta", "optimize this prompt/file against my traces", "auto-optimize against LLM-Obs", or wants the local equivalent of the auto\_experiments worker. Works from an ml\_app, a dataset\_id, an annotation\_queue\_id (a queue of human-labelled interactions), a list of trace\_ids, or (by exception) a local dataset file. The corpus and its val/test splits live in Datadog LLM-Obs Datasets, created once per run with a timestamp in their names.](https://skilld.dev/gh/datadog-labs/agent-skills/agent-observability-auto-experiment)

  Datadog Labs · datadog-labs/agent-skills 176

  Fit a Datadog LLM-Obs evaluator to human labels. Takes an annotation queue, works out where in the trace the labelled property actually lives, drafts an LLM-judge that predicts the human label, scores that judge against the already-labelled rows with a metric agreed with the user, then hill-climbs it — inspect the errors, make one focused change, re-score, keep it only if it beats the best — for a bounded number of iterations, and finally publishes the winner to Datadog as a DISABLED evaluator (not a Datadog draft — a real evaluator with \`enabled: false\`). Use when the user says "build an eval from my annotations", "build an evaluator from the annotation queue", "turn my annotations into an evaluator", "learn an evaluator from my labels", "fit a judge to the annotation queue", "auto-label", "auto labelling", "automate this annotation queue", "scale up my human labels", or wants the rest of a queue graded the way the humans graded the first rows. Needs an annotation queue with at least two classes present in the human labels (e.g. one true and one false for a boolean).](https://skilld.dev/gh/datadog-labs/agent-skills/agent-observability-build-eval-from-annotations)

  Bootstrap evaluators from production traces — by default propose online LLM-judge evaluators and, after you confirm, create them in Datadog as disabled drafts (never auto-enabled); on request emit Python SDK code or a framework-agnostic JSON spec instead. Use when user says "bootstrap evaluators", "generate evaluators", "create evals from traces", "eval bootstrap", "write evaluators", "build eval suite", "publish evaluators", or wants to generate BaseEvaluator/LLMJudge code or online judge configs from production LLM trace data.

  End-to-end Agent Observability pipeline for an instrumented ml\_app — classify production traces, root-cause failures, bootstrap evaluators, then (optionally) sample + publish a dataset, generate + run an experiment, and analyze results. Six narrated phases with a standardized banner and a "continue" checkpoint between each. Pure orchestration over the agent-observability sub-skills (\`agent-observability-session-classify\`, \`agent-observability-trace-rca\`, \`agent-observability-eval-bootstrap\`, \`agent-observability-experiment-bootstrap\`, \`agent-observability-experiment-analyzer\`).

Stop early with \`--stop-after \<phase>\` to short-circuit at evaluators or dataset, or resume mid-flow with \`--start-at \<phase>\`.](https://skilld.dev/gh/datadog-labs/agent-skills/agent-observability-eval-pipeline)
