Solution Reference: Bonus A -- Improve an Agent

This shows an example improvement PR for an existing accessibility agent.

Example improvement

Target agent: aria-specialist.agent.md

What I changed: Added a new responsibility for checking aria-live regions in dynamic content. The existing agent covered static ARIA roles but did not mention live regions, which are critical for screen reader users interacting with content that updates without a page reload.

Before (responsibilities excerpt):

- Check that interactive elements have correct ARIA roles
- Verify that ARIA states match the visual state of components

After (with addition):

- Check that interactive elements have correct ARIA roles
- Verify that ARIA states match the visual state of components
- Review aria-live regions for appropriate politeness levels (polite vs assertive) on dynamic content updates

PR description:

Adds live region checking to the ARIA specialist agent's responsibilities.

Dynamic content updates (search results, notifications, form validation messages) need aria-live attributes so screen readers announce changes. The agent currently checks static ARIA attributes but not live regions. This addition closes that gap.

What matters

The learning objective is contributing to an existing project by understanding its conventions and making a targeted improvement. If you identified a real gap and proposed a specific, well-reasoned change, you completed this bonus.
