GitNexus CLI Commands
All commands work via npx — no global install required.
Commands
analyze — Build or refresh the index
npx gitnexus analyzeRun from the project root. This parses all source files, builds the knowledge graph, writes it to .gitnexus/, and generates CLAUDE.md / AGENTS.md context files.
| Flag | Effect |
|---|---|
--force | Force full re-index even if up to date |
--embeddings | Enable embedding generation for semantic search (off by default) |
--drop-embeddings | Drop existing embeddings on rebuild. By default, an analyze without --embeddings preserves them. |
When to run: First time in a project, after major code changes, or when gitnexus://repo/{name}/context reports the index is stale.
status — Check index freshness
npx gitnexus statusShows whether the current repo has a GitNexus index, when it was last updated, and symbol/relationship counts. Use this to check if re-indexing is needed.
clean — Delete the index
npx gitnexus cleanDeletes the .gitnexus/ directory and unregisters the repo from the global registry. Use before re-indexing if the index is corrupt or after removing GitNexus from a project.
| Flag | Effect |
|---|---|
--force | Skip confirmation prompt |
--all | Clean all indexed repos, not just the current one |
wiki — Generate documentation from the graph
npx gitnexus wikiGenerates repository documentation from the knowledge graph using an LLM. Requires an API key (saved to ~/.gitnexus/config.json on first use).
| Flag | Effect |
|---|---|
--force | Force full regeneration |
--model <model> | LLM model (default: minimax/minimax-m2.5) |
--base-url <url> | LLM API base URL |
--api-key <key> | LLM API key |
--concurrency <n> | Parallel LLM calls (default: 3) |
--gist | Publish wiki as a public GitHub Gist |
list — Show all indexed repos
npx gitnexus listLists all repositories registered in ~/.gitnexus/registry.json. The MCP list_repos tool provides the same information.
After Indexing
- Read
gitnexus://repo/{name}/contextto verify the index loaded - Use the other GitNexus skills (
exploring,debugging,impact-analysis,refactoring) for your task
Troubleshooting
- "Not inside a git repository": Run from a directory inside a git repo
- Index is stale after re-analyzing: Restart Claude Code to reload the MCP server
- Embeddings slow: Omit
--embeddings(it's off by default) or setOPENAI_API_KEYfor faster API-based embedding
