# crucible-agent-create-commit-registry > Create and commit a registry-ready single-agent repository that generates technical solution design documents and draw.io architecture diagrams from application requirements. A tool, not a standing agent service — see `input.schema.json`/`output.schema.json` for its contract. Generated by crucible-agent-decomposer for a plan gap step; language and structure are whatever the capability actually needs, not a fixed layout.
