New consortium proposes machine-readable accessibility assertion format for CI pipelines

Tech · 5 min read

Tool vendors, auditors, and open-source maintainers have published a draft machine-readable format for accessibility assertions intended to standardize how automated tests report findings. The proposal focuses on consistency — each report contains the element selector, failure reason, suggested fix, severity, and token references if applicable — so downstream systems can group results across different testing tools.

Standardizing results would make it straightforward to integrate a11y output into build dashboards, issue trackers, and design-system release notes. For example, a design system release pipeline could automatically convert assertion reports into prioritized remediation tickets linked to component stories and token changes.

The draft intentionally avoids mandating a set of checks; instead, it specifies a minimal payload for interoperability. Tool vendors are already experimenting with adapters that emit the new format, and early adopters say it reduces noise by enabling rule-based triage and grouping of related failures that span HTML, CSS, and token mismatches.
