Read `spec/commands/speccraft.tech-design.md` in full, then create the LLD(s) for the business spec file provided. Input: read the business spec file path the user supplied after invoking this skill. Rules before starting: - confirm the business spec file exists and is readable - active phase must be planning - read `spec/architecture/ARCH-DECISIONS.md` §Layer Scope first (ask interactively if absent and the file is empty/placeholder — never infer) - read all documents listed in the "Documents This Command Must Use" section of spec/commands/speccraft.tech-design.md - produce the LLD(s) for this project's Layer Scope — LLD-FRONTEND-<id>.md and/or LLD-BACKEND-<id>.md — in spec/lld/; when Layer Scope = both, each cites a Companion LLD Reference naming its pair - update traceability in the current story's shard: spec/traceability/<mirrored-business-path>/TRACEABILITY.md - after producing every in-scope LLD: output all path(s) + summary + minimal handoff block, then STOP - do not invoke /speccraft.decompose - do not self-approve any LLD - wait for human approval (covering every in-scope LLD as one gate) before any downstream stage runs The canonical contract documents dual-LLD output as the default shape when Layer Scope = both, and single-artifact output for frontend-only or backend-only projects.
