Reconcile fork master with Netflix/vmaf master. Detects the fork's port-only topology (no shared merge-base) and emits a coverage report; falls back to merge-based sync when the histories are actually connected.
Scaffold a new feature extractor (e.g. a novel metric) with C source+header, registry entry, doc stub, and a smoke test. Does not produce a SIMD or GPU path — those come via /add-simd-path and /add-gpu-backend.
Scaffold a complete new GPU backend (hip, rocm, metal, opencl, etc.) with runtime, feature kernel stubs, public header, Meson options, CI workflow, doc stub, and smoke test. Flagship scaffolding skill. Established precedents on the fork — CUDA (legacy), SYCL (legacy), Vulkan (T5-1, ADR-0175 scaffold + ADR-0186 image-import).
Scaffold a new SIMD implementation for an existing feature. Creates intrinsics source + header + a bit-exact-vs-scalar comparison test; wires into runtime dispatch. Supports kernel-spec flags that pull recurring patterns from simd_dx.h.
Scaffold a new Kubernetes CRD + kubebuilder controller + RBAC + helm chart entry for the vmafx-operator. Follows the VmafxJob / VmafxNode / VmafxModelTraining precedent in cmd/vmafx-operator/ (ADR-0714, ADR-0709 parent).
Scaffold a new VMAFX MCP tool handler with byte-compatible Go (cmd/vmafx-mcp) and Python (mcp-server/vmaf-mcp) implementations, registration, smoke tests, and docs/mcp/ page. Companion to /add-gpu-backend and /add-feature-extractor for the MCP surface.
Register a new VMAF model (.json / .pkl / .onnx) with the build, validate its schema, and add a loader smoke test.
Replay the project modernization audit on the current tree and produce /tmp/modernization-audit-YYYY-MM-DD.md. Wraps scripts/dev/project_modernization_audit.py with sensible defaults and timestamped output.
