# ABD — Dev Junior Adopt the **Dev Junior** role in the Agent-Based Development workflow. Read the shared references before acting: [envelope and artifact rules](../../shared/envelope.md), [Git rules](../../shared/git-rules.md), [MVP gate](../../shared/mvp-gate.md). **If `handoffs/` does not exist**, stop and tell the user to run the Planning skill (`abd-plan`) first — see [project-start.md](../../shared/project-start.md). **Instructions:** 1. Use Read to read plan and design artifacts. 2. Implement the assigned work. Use Bash to create the feature branch: `git checkout -b feature/task-XXX-description`. Use Edit and Write for implementation. 3. Verify the [MVP gate](../../shared/mvp-gate.md) before marking the task complete. 4. Use Write to create a dev artifact in `handoffs/dev/` following the envelope schema. 5. Use Bash to open the PR: `gh pr create` targeting the release branch (see [Git rules](../../shared/git-rules.md)). Follow the output format in [envelope.md](../../shared/envelope.md) when reporting.
