    "why": "A security check is only worth as much as the record of what it checked. Nuclei writes each check as one readable YAML template and verifies it by sending the real request, so findings carry their evidence and false positives stay low — with thousands of community templates to draw on.",
    "take": "Because a template is readable, you can check what a rule actually looks at and change it — which is what makes a scanner worth trusting.",
    "build": [
      "A Go CLI covering HTTP, TCP, DNS, SSL, WHOIS, JavaScript and more, clustering requests to scan fast in parallel. It fits into CI as a regression check and reports into Jira, Splunk, GitHub, Elastic or GitLab. The documentation includes Korean."
