speccraft.decomposelisted

Read `spec/commands/speccraft.decompose.md` in full, then decompose the approved, in-scope LLD(s) into delivery tasks. Input: read the LLD file path(s) the user supplied after invoking this skill — `<lld-fe-file> <lld-be-file>` when Layer Scope = both, or `<lld-file>` for a single-layer project. Rules before starting: - confirm every in-scope LLD file exists and its status is `approved` - confirm the argument count matches this project's Layer Scope (`spec/architecture/ARCH-DECISIONS.md` §Layer Scope) - active phase must be planning - read all documents listed in the "Documents This Command Must Use" section of spec/commands/speccraft.decompose.md - produce task files, each with a mandatory Layer: frontend|backend field, in spec/tasks/<module>/ (mirrored per business module, flat, no tasks/ subfolder) - update traceability in the current story's shard: spec/traceability/<mirrored-business-path>/TRACEABILITY.md - after producing tasks: output task list + execution order + sizing rationale + minimal handoff block, then STOP - do not begin execution or scaffold - do not self-approve the decomposition - wait for human approval before execution begins The canonical contract documents the dual-input signature (`/speccraft.decompose <lld-fe-file> <lld-be-file>`) for Layer Scope = both, a single-file signature for single-layer projects, and the mandatory Layer field on every emitted task.
