Create native editable draw.io diagrams as .drawio files and optionally export them to PNG, SVG, PDF, JPG, or browser URLs. Use when Codex needs to create, generate, draw, or design a diagram, flowchart, architecture diagram, ER diagram, sequence diagram, class diagram, network diagram, mockup, wireframe, UI sketch, or work with draw.io, drawio, drawoi, .drawio files, or diagram export.

Summarize the current conversation into a handoff file saved to ~/.claude/handoffs/

Automate browser interactions, test web pages and work with Playwright tests.

PyTorch model-building conventions and a neural-net training debug checklist. Use this skill whenever writing or reviewing PyTorch code that defines a model (nn.Linear, nn.Conv2d, BatchNorm) or trains one (training loop, optimizer, LR schedule), and ESPECIALLY when debugging training problems — loss not converging, loss stuck or flat, suspiciously slow learning, "hockey stick" loss curves, or a model that seems to ignore its inputs. Also consult it before starting any from-scratch training run, even if the user doesn't mention debugging.
