def-graph skillA

def-graph is agent-read markdown (skill) from shenshan123/r2g-skills: Convert clean, signed-off physical-design files (DEF/LEF/liberty/SPEF from an ORFS backend run) into training-ready PyTorch-Geometric graph datasets. Use when the user wants to build a graph dataset from placed-and-routed designs — the five graph views (b–f), the tech-lib/LEF/DEF parser, node/edge feature extraction, or per-cell/per-net labels (congestion, RC parasitics, wirelength, timing, IR drop). Companion to the signoff-loop skill, which produces the physical-design inputs this skill consum.

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.

How to install

Latest version
mdr add shenshan123/r2g-skills/def-graph@git:20260801.67e1f6f
Exact content

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
