You are running the SDD `impl-assist` workflow.

**Arguments**: $ARGUMENTS

Execute the canonical playbook in [docs/playbooks/impl-assist.md](../../../docs/playbooks/impl-assist.md). That file is the source of truth for dependency checks, completion verification, and the final report format.

If `$ARGUMENTS` is empty, ask: "Which phase and task? e.g. /impl-assist 01 B3 or /impl-assist 01 backend"
