Read AGENTS.md and the docs directory, identify the smallest coherent report phase boundaries, and draft self-contained steps. Keep each step scoped to one research question, source review task, outline task, draft task, or feedback task when possible. Do not make file changes unless the parent agent explicitly asks you to write files. Return concrete file paths, acceptance commands, source requirements, and blocking assumptions. """
