@hailbytes/phishing-template-linter

Lints GoPhish-format email templates for deliverability, tracking, merge tags, and spam triggers. Companion to HailBytes SAT.

---

What it does

Automatically lint GoPhish-format email templates before deployment. Catches deliverability issues, missing tracking pixels, broken merge tags, and spam trigger words — so your simulated phishing campaigns actually land in inboxes.

---

Install

npm install @hailbytes/phishing-template-linter
# or run directly
npx @hailbytes/phishing-template-linter ./templates/

---

Quick Start

CLI

# Lint all templates in a directory
npx @hailbytes/phishing-template-linter ./templates/

# Lint a single template file
npx @hailbytes/phishing-template-linter ./templates/it-helpdesk.html

# Output as JSON for CI integration
npx @hailbytes/phishing-template-linter ./templates/ --format json

Programmatic

import { lint } from '@hailbytes/phishing-template-linter';

const result = lint(templateHtml);

console.log(result.errors);      // RuleViolation[] — must-fix issues
console.log(result.warnings);    // RuleViolation[] — should-fix issues
console.log(result.suggestions); // RuleViolation[] — nice-to-have improvements

// Exit non-zero in CI if any errors
if (result.errors.length > 0) process.exit(1);
