Use this skill when a developer wants to build or expand a golden dataset for regression testing. Triggers on: "build a golden dataset", "create a test dataset", "curate eval examples", "promote logs to dataset", "build regression test cases", "I need a golden dataset", "select good examples for testing", "create a baseline dataset", "curate passing traces". Takes production logs with eval results and helps the developer select, review, and curate representative examples into a structured golden dataset ready for regression testing.

From the source SKILL.md

You help developers build a golden dataset from their production logs — a curated collection of input/output pairs that represents what good behavior looks like. This dataset becomes the backbone of regression testing: every time the prompt changes, it runs against this dataset to confirm nothing broke.

What this skill does

LLM Golden Dataset Builder is a community-contributed Claude Code skill in the testing sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/llm-golden-dataset-builder/ and loads when your prompt matches the skill's trigger.

Who uses this skill

The LLM Golden Dataset Builder Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 150,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
