Story arc

How this shipped

Building the tools that build the toolsThree beats: what pressed against the work, how the stack answered, and what changed once it was live.

I · Constraint

The brief

Accessibility testing tools are either too complex (full audit suites) or too simple (basic checkers). Developers need actionable fixes, not just problem lists.

II · Build

The craft

Built CLI that provides real-time auto-fix suggestions with impact scoring. Prioritizes issues by severity and fix difficulty. Published to npm for easy integration into any project.

III · Proof

What moved after launch

Published on npm as ally-a11y. GitHub Actions CI/CD ensures reliability. Impact scoring helps teams prioritize high-value fixes. Auto-fix suggestions cut the manual remediation step on each finding.
