Why it matters

Missing alt text leaves screen-reader users with no context for images. An empty alt="" is only acceptable for decorative images that carry no information.

Configure this check

Override the default severity in your ESLint config:

import astroDoctorPlugin from '@santi020k/eslint-plugin-astro-doctor'

export default [
  astroDoctorPlugin.configs.recommended,
  {
    rules: {
      'astro-doctor/no-missing-alt': 'error',
    },
  },
]

Or set the severity for CLI scans in doctor.config.ts:

export default {
  rules: {
    'astro-doctor/no-missing-alt': 'error',
  },
}

Use 'error', 'warn', or 'off'. The configuration guide covers presets and per-file overrides.
