What problem does it solve? New developers joining a project often spend days reading code to understand architecture, key files, and risky areas. This Skill turns an existing knowledge graph into a structured onboarding guide so newcomers get a curated learning path instead of raw exploration. ## Core Features & Use Cases - Graph-driven guide generation: Reads project metadata, architecture layers, guided tour steps, and file-level nodes from knowledge-graph.json to build a complete onboarding document. - Freshness validation: Compares the graph's recorded git commit against the current HEAD and project-scoped diffs, warning when the graph may be stale before generating content. - Complexity hotspot detection: Surfaces the highest-complexity files so new developers know which areas to approach carefully. - Use Case: A new engineer joins a monorepo team. Run this Skill to produce a markdown guide with project overview, architecture layers, a guided tour, a file map, and complexity hotspots, then save it to docs/UA_ONBOARDING.md and commit it for the whole team. ## Quick Start Ask the assistant to generate an onboarding guide for new team members from the project's knowledge graph.
