Clone target repos, install asdf toolchains, and run make validate baselines with a self-verify retry loop
Walk the operator through every RuntimeConfig section and produce a valid backlog/config/devbench.yaml
Author a rigorous engineering specification at the depth `spec-to-backlog` requires, matching the operator's workspace exemplar (when configured) or the embedded 16-section skeleton otherwise; then offer spec-to-backlog handoff
Decompose an engineering specification into a 4-level backlog (Epic -> Feature -> Story -> Task) at the depth the validator + orchestrator require, matching whatever exemplar the operator's workspace points at (or the embedded canonical-section list when no exemplar is configured)
Run the devbench backlog execution loop until all work units are complete or blocked
