signoff-loop skillA

signoff-loop is agent-read markdown (skill) from shenshan123/r2g-skills: Drive an open-source EDA workflow from RTL to GDS with full signoff (DRC, LVS, RCX) using OpenROAD-flow-scripts (ORFS), Yosys, KLayout, Magic, Netgen, and OpenRCX — plus a self-improving observation→ingest→act loop that learns repair recipes to eliminate DRC/LVS violations and close timing at the best Fmax. Use when the user wants to turn a hardware spec or RTL into synthesis, place-and-route, GDS output, signoff verification, parasitic extraction, PPA iteration, flow-failure diagnosis, autonomo.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
