Validate Gherkin feature files for structural quality, determinism, and implementation independence, then verify each scenario has matching test automation. Use this skill whenever reviewing test files, feature files, or BDD scenarios — including during /code-review when .feature files or step definition files appear in the changeset. Also use when a user asks to "check my feature files", "validate my Gherkin", "are my scenarios testable", or "do my feature files have tests".

From the source SKILL.md

Feature files are the contract between intent and implementation. This skill validates two things: (1) are scenarios well-formed, deterministic, and behavioral? (2) does every scenario have matching test automation?

What this skill does

Feature File Validation is a community-contributed Claude Code skill in the product-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/feature-file-validation/ and loads when your prompt matches the skill's trigger.

When to invoke it: use when a user asks to "check my feature files", "validate my Gherkin", "are my scenarios testable", or "do my feature files have tests".

Who uses this skill

The Feature File Validation Claude Code skill is built for product managers, product designers, and cross-functional teams planning, shipping, and measuring product features. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 211,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
