Gitnexus CLI Skill for Claude

GitNexus CLI Commands

All commands work via npx — no global install required.

Commands

analyze — Build or refresh the index

npx gitnexus analyze

Run 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) |

When to run: First time in a project, after major code changes, or when gitnexus://repo/{name}/context reports the index is stale. In Claude Code, a PostToolUse hook runs analyze automatically after git commit and git merge, preserving embeddings if previously generated.

status — Check index freshness

npx gitnexus status

Shows 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 clean

Deletes 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 wiki

Generates 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 list

Lists all repositories registered in ~/.gitnexus/registry.json. The MCP list_repos tool provides the same information.

After Indexing

• Read gitnexus://repo/{name}/context to 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 set OPENAI_API_KEY for faster API-based embedding
