Code Graph Build a deterministic, machine-readable code graph for a single repository. Treat the graph as a machine-readable substrate for an LLM-maintained repo wiki or context hub, not just a terminal-only report. This skill mirrors the artifact workflow, but works at file and symbol level instead of portfolio level. Use this skill when you need: - a committable artifact - file and symbol maps for one repo - import, call, inheritance, and test-link analysis - graph-theory review signals such as articulation points, bridges, cycles, topological order, and alternate paths - blast radius and m…
