What problem does it solve? Managing a GitNexus code index requires knowing the right CLI commands, flags, and recovery steps when the index is missing, stale, or corrupt. This Skill provides the exact command reference for indexing a repo, checking index freshness, cleaning the index, and generating wiki documentation from the knowledge graph. ## Core Features & Use Cases - Index Management: Build or refresh the repository knowledge graph with analyze, check freshness with status, and delete corrupt indexes with clean. - Wiki Generation: Generate LLM-based repository documentation from the knowledge graph, with options for model selection, concurrency, and publishing as a GitHub Gist. - Runner Fallbacks: Uses the project-local node .gitnexus/run.cjs runner that auto-selects a global install, pnpm dlx, or npx, with recovery steps for fresh clones and npm 11.x install crashes. - Use Case: After cloning a repo, run the analyze command to build the knowledge graph and generate CLAUDE.md/AGENTS.md context files, then verify the index loaded before using other GitNexus exploration skills. ## Quick Start Ask the agent to index this repository with GitNexus and then check the index status to confirm it is up to date.
