+# Worker Rails
+
+## Constraints for Coding Stage Workers
+
+### MUST
+
+- Work only on files listed in the context packet
+- Follow patterns specified in the implementation spec
+- Use git worktree at `~/src/<repo>-worktrees/<task-slug>`
+- Push to a feature branch
+- Open a PR with description referencing the task ID
+- Run lint + typecheck + unit tests before declaring done
+- Self-check against acceptance criteria
+
+### MUST NOT
+
+- Make architectural decisions (those were made in Planning 1-2)
+- Refactor unrelated code
+- Edit files outside write scope
+- Introduce new dependencies without spec approval
+- Change API contracts without spec approval
+- Merge PRs (workers NEVER merge)
+- Skip tests defined in acceptance criteria
+- Work in main checkout or /tmp (always worktree)
+
+### On Confusion
+
+If the context packet is unclear or the spec seems wrong:
+
+1. Do NOT guess and proceed
+2. Do NOT make your own architectural decisions
+3. STOP and report the ambiguity back to the orchestrator
+4. The orchestrator will route the question back to the appropriate planning stage
+
+### On Completion
+
+1. Push branch
+2. Open PR
+3. Report: task ID, branch name, acceptance criteria status
+4. EXIT — do not continue to other tasks
