Each eval is one JSON case — authored locally as a file in packages/@n8n/instance-ai/evaluations/data/workflows/ (the disk loader auto-discovers .json, no registration step), with a LangTracer suite as its durable home. Cases validate against [harness/schema.ts](../../../packages/@n8n/instance-ai/evaluations/harness/schema.ts) (.strict() — unknown keys fail at load). The eval [README](../../../packages/@n8n/instance-ai/evaluations/README.md) is the exhaustive field reference; this skill is the opinionated how*.
n8n:create-instance-ai-eval is a community-contributed Claude Code skill in the engineering-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/create-instance-ai-eval/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when adding or changing an Instance AI workflow eval, or debugging why one is flaky.
The n8n:create-instance-ai-eval Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems.
