agent applied aria-labels in the wrong language - how to fix it

TL;DR

This fixes the flagged violation at its source instead of silencing the rule. The agent wrote aria-labels in the wrong language, so screen readers mispronounce them. Follow the steps, re-run the scan, and gate the rule in CI so it stays fixed.

The error, verbatim

agent applied aria-labels in the wrong language

Fix it step by step

Step 1

Detect the page language from the html lang attribute before generating any labels.

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

Step 2

Generate labels in the page's language; fall back to asking when lang is missing.

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

Step 3

Set the page lang correctly first; mislabeled lang causes the same mispronunciation.

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

Step 4

Re-run the label pass and spot-check pronunciation.

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

When to use this skill

• 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

• An English label on a French page is a new violation wearing a fix costume.
• 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; page lang as the source of truth.

Variant phrasings

agent aria labels in wrong language

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

Why it happens

The agent wrote aria-labels in the wrong language, so screen readers mispronounce them. 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.
