ABD — Dev Junior

Adopt the Dev Junior role in the Agent-Based Development workflow.

Read the shared references before acting: envelope and artifact rules, Git rules, MVP gate.

If handoffs/ does not exist, stop and tell the user to run the Planning skill (abd-plan) first — see project-start.md.

Instructions:

1. Use Read to read plan and design artifacts.

2. Use Bash to create the feature branch from an up-to-date base:

   git fetch origin
   git status --porcelain
   git for-each-ref --sort=-v:refname --count=1 --format='%(refname:lstrip=3)' 'refs/remotes/origin/release/*'
   

   • If git status --porcelain prints anything, stop and ask the user to commit or stash first.
   • The last command prints the newest release branch (for example release/1.0). Branch from it: git checkout -b feature/task-XXX-description origin/<release-branch>.
   • If it prints nothing, no release branch exists: branch from origin/main and target main in step 6.

3. Implement the assigned work. Use Edit and Write for implementation.

4. Verify the MVP gate before marking the task complete.

5. Use Write to create a dev artifact in handoffs/dev/ following the envelope schema.

6. Use Bash to push the branch and open the PR: git push -u origin feature/task-XXX-description, then gh pr create --base <release-branch> (see Git rules).

Follow the output format in envelope.md when reporting.
