agent alt-text generator described decorative images instead of empty alt - how to fix it

TL;DR

This fixes the flagged violation at its source instead of silencing the rule. The agent wrote descriptive alt text for decorative images instead of leaving them empty, so screen readers announce noise. Follow the steps, re-run the scan, and gate the rule in CI so it stays fixed.

The error, verbatim

agent alt-text generator described decorative images instead of empty alt

Fix it step by step

Step 1

Mark decorative images with empty alt so assistive tech skips them.

Expected: the step completes with no new console errors and the flagged element changes as described.

Step 2

Teach the agent a decorative-vs-informative classifier: icons, dividers, and stock filler are decorative.

Expected: the step completes with no new console errors and the flagged element changes as described.

Step 3

For informative images, keep the agent's descriptive alt; only the decorative ones change.

Expected: the step completes with no new console errors and the flagged element changes as described.

Step 4

Re-run axe image-alt and spot-check with a screen reader.

Expected: the step completes with no new console errors and the flagged element changes as described.

When to use this skill

• Your scan report lists this exact rule or failure
• You are clearing automated accessibility failures before release or audit
• A CI accessibility gate is red because of this item

When NOT to use this skill

• Empty alt is the correct accessible choice for decoration, not a missing label.
• The issue only appears in manual screen-reader testing and no automated rule flags it
• You are doing a full manual WCAG audit; this skill covers one automated check

Compatibility

Agent workflow guardrail; verify with axe image-alt.

Variant phrasings

agent alt text on decorative images should be empty alt

Same underlying issue and the same fix. Searchers phrase it different ways; the remediation does not change.

Why it happens

The agent wrote descriptive alt text for decorative images instead of leaving them empty, so screen readers announce noise. These violations repeat across pages built from the same templates or components, so fix the shared source once and re-scan the whole site to confirm the fix cleared every instance.

axe-core image-alt missing alt attribute error - how to fix it

TL;DR

Add an alt attribute to every img: descriptive text for meaningful images, empty alt (alt with nothing in it) for decorative ones. Missing entirely is the failure, empty is fine for decoration. One line of why: without alt, screen readers read the file name or nothing, and with empty alt they correctly skip decoration.

The error, verbatim

{
  "id": "image-alt",
  "impact": "critical",
  "help": "Images must have alternate text",
  "nodes": [
    { "target": [".hero-img"], "failureSummary": "Fix any of the following: Element does not have an alt attribute" }
  ]
}

Fix it step by step

Step 1: Reproduce on one page

npx @axe-core/cli https://example.com --rules image-alt --save axe-img.json

Expected: Violations array contains image-alt with the img selectors.

Step 2: List the offending images

node -e "const r=require('./axe-img.json'); r.violations[0].nodes.forEach(function(n){console.log(n.target.join(' '))})"

Expected: Selectors for each img missing the attribute.

Step 3: Find them in source

rg -n --glob '*.{jsx,tsx,vue,html}' 'img src' src | head -30

Expected: Shows img usages; check each for a missing alt attribute. (Adjust the pattern to your templating if needed.)

Step 4: Add alt text and re-scan

npx @axe-core/cli https://example.com --rules image-alt

Expected: Exit code 0, 0 violations. Screen reader announces meaningful images and skips decorative ones.

Step 5: Gate the rule in CI

npx @axe-core/cli https://example.com --exit | tail -3

Expected: Non-zero exit while any violation remains; add this command to CI so the fix never regresses.

When to use this skill

• Your axe-core report lists this exact rule id under violations
• You are clearing automated WCAG 2.1 AA failures before a release or audit
• A CI a11y gate (pa11y-ci, lighthouse CI, cypress-axe) is red because of this rule

When NOT to use this skill

• The issue only shows up in manual screen-reader testing and axe reports zero violations for the rule
• You are doing a full manual WCAG audit, this skill covers the single automated rule only
• The page is a third-party embed you cannot edit, flag it to the vendor instead

Compatibility

axe-core 4.8+ (rule image-alt, WCAG 1.1.1). Same rule in pa11y, lighthouse, and axe DevTools. Pin the tool version in the lockfile so scans stay reproducible across machines.

Variant phrasings

element does not have an alt attribute

The failureSummary wording, same fix.

axe img missing alt text

Short practitioner phrasing for the same rule.

axe DevTools flags the same rule

The browser extension runs the same rule engine; fix once and it clears in every runner.

Why it happens

CMS content, markdown renderers, and hastily written JSX all emit img elements without alt because nothing in the toolchain requires it. Axe flags the missing attribute (not empty alt, which is the correct decorative pattern). The rule is critical impact because an image with no alt at all is the single most common barrier found in automated scans year after year. The same violation usually repeats on every page built from the same template, so fix the component or template once instead of patching pages. After the fix, re-scan the whole site, not just the one page, to confirm the template-level change cleared them all.

Edge cases

• Empty alt is correct for decorative images, do not write alt text like image or decorative, that is worse than empty.
• Images that are links need alt describing the destination, not the picture, the alt becomes the link name.
• Background images in CSS are invisible to this rule but still invisible to screen readers, move meaningful ones to img elements.
• Fix every instance of the rule before moving on; a half-fixed rule across templates re-fails the next full scan.

TL;DR

Fix this in Freshdesk by acting on the exact symptom first: add the alt text in the article HTML view after uploading the image, save, and recheck the published page source, because the visual editor upload path drops the attribute on insert. Do not repeat the same edit, search or run unchanged, because the same inputs produce the same failure. Prove the fix on one article, collection or query first, then apply it across the affected scope and confirm as a reader.

Freshdesk article image alt text is stripped, failing accessibility audit checks

Use this when

• Work in Freshdesk shows this exact symptom: Freshdesk article image alt text is stripped, failing accessibility audit checks.
• The same symptom repeats after a retry with unchanged inputs.
• Readers or support agents are blocked until this item is corrected.

Not for this skill when

• The help center platform itself is down or returning outage notices. Resolve that first, then return here if this symptom remains.
• The content is correct and you only want a style or tone rewrite. That is an editorial pass, not this fix.

Steps

1. Reproduce the symptom with the smallest scope that still shows it in Freshdesk, and record the article, collection or query involved plus the exact wording from the code block above. Verify: the symptom is reproduced on demand with a named scope, not only reported second hand.
2. Apply the specific fix for this symptom: add the alt text in the article HTML view after uploading the image, save, and recheck the published page source, because the visual editor upload path drops the attribute on insert. Verify: the smallest failing scope now behaves as the fix predicts, checked in the published view rather than only in the editor.
3. Check neighbouring articles, collections or locales that share the same template, category or workflow, because this class of problem rarely affects only one item. Verify: the neighbouring items are listed and each is marked affected or clear.
4. Repeat the original reader or agent action in Freshdesk that exposed the symptom, using the same query, link or workflow as the first attempt. Verify: the action completes and the original symptom does not appear.
5. Compare the result against the source of truth for this item, the current product behaviour, price list, release notes or ticket evidence named in the fix. Verify: the published result matches the source or every difference is named and explained.
6. Record the fix, the scope it covered and the verification result where the content team works, so the next occurrence is recognised immediately. Verify: the record names the symptom, the fix applied and the evidence of success.

How to fix - Freshdesk article image alt text stripped failing accessibility audit checks

The how to phrasing for the same problem in Freshdesk. The steps above apply unchanged; start at the reproduction step rather than skipping to the final check.

Freshdesk troubleshooting for this symptom

The symptom first phrasing used when the full message is hidden. Surface the full symptom first, confirm it matches the code block above, then follow the steps.

Why it happens

The editor inserted images without carrying the alt attribute into the saved markup, so screen readers and audits found images with no description at all.

Edge cases

• The symptom appears in one locale, collection or audience view only. Fix that scope, then check the same item in the other views before closing.
• A cached or indexed copy keeps showing the old state after the fix. Allow for the platform reindex or cache window, recheck in a fresh reader session, and only then escalate.
• Two items have near identical titles. Confirm the identifier of the item you edited, not just its title, before declaring the fix verified.

Compatibility: Freshdesk at current versions, plus the help center admin, search or API surface the query names; no extra tooling beyond reader level access to verify the published result.
