/implement-mock — Add a faithful mock to tt-emule

You've identified a silicon API that tt-emule needs to mock (or a mock that's diverging from silicon). This skill walks the end-to-end workflow.

Usage

/implement-mock <silicon_function_or_concept>
/implement-mock noc_async_write_tile
/implement-mock llk_unpack_AB_matmul
/implement-mock TensorAccessor::get_noc_addr

Step 1 — Look up the HW spec
