Key themes include: AI models trained on inaccessible human-written code propagate existing biases at scale; deterministic testing is essential because AI output is non-deterministic; prompting alone cannot reliably produce accessible code; GitHub's internal accessibility agent achieved ~60% PR resolution rates using curated bug data with WCAG-tagged diffs; harness and context engineering are high-leverage opportunities for accessibility practitioners to embed inclusive defaults into agentic workflows; and the pull request, while necessary, is too late as the sole gate — accessibility must be shifted left into design and code generation phases. Panelists from Deque Systems, University of Washington, GitHub, and Evinced share practical strategies including MCP-based remediation tools, custom instruction files, and just-in-time developer training via PR feedback. ## Full article daily.dev links to this article rather than hosting it.
