Hey Jim, thanks for the intro. Everything we build is open source, so the best way to plug in is through the repos directly. Start here: github.com/opena2a-org. We keep contributor-friendly issues labeled good-first-issue. Pick one, comment on it so we know you're on it, and open a PR. All contributions get named credit. Before that, drop your GitHub handle here so we can see what you've worked on. That helps us point you at issues that fit your background. If your first couple of PRs land well, there's a lot more surface area, including credited contributions to the Agent Threat Matrix.
