GitNexus CLI
Analyze, index, and generate wikis for your codebase via command line.
Installation
- Make sure Claude is on your device and in your terminal.
Skills load from
~/.claude/skills/when Claude Code starts up — so you need it on your machine first. If you don't have it yet, install it once with the command below, then runclaudein any terminal to verify.One-time setupnpm i -g @anthropic-ai/claude-codeAlready have it? Skip ahead.
- Paste into Claude Code or into your terminal.
This copies the whole skill folder into
~/.claude/skills/gitnexus-cli-abhigyanpatwari/— the SKILL.md plus any scripts, reference docs, or templates the skill ships with. Safe default: works for every skill.Faster alternative (instruction-only skills)
Skips the clone and grabs only the SKILL.md file. Don't use this if the skill ships Python scripts, reference markdowns, or asset templates — they won't be downloaded and the skill will fail when it tries to load them.
Quick install (SKILL.md only)Sign up to copy - Restart Claude Code.
Quit and reopen Claude Code (or any other agent that loads from
~/.claude/skills/). New skills are picked up on startup. - Just ask Claude.
Skills auto-activate when your request matches the skill's description — no slash command needed. Trigger phrases live in the skill's own frontmatter; you can read them in the “What this skill does” section above.
Prefer to read the source first? Open on GitHub.
When Claude uses it
Use when the user needs to run GitNexus CLI commands like analyze/index a repo, check status, clean the index, generate a wiki, or list indexed repos. Examples: "Index this repo", "Reanalyze the codebase", "Generate a wiki"
What this skill does
GitNexus CLI Commands
Commands below use node .gitnexus/run.cjs <command> — the project-local runner gitnexus analyze drops next to the index. It auto-selects an available runner at call time (global gitnexus, else pnpm dlx, else npx), so no package-manager assumption and no global install is required.
Not analyzed yet, or
node .gitnexus/run.cjsreportsCannot find module(the gitignored runner is absent — e.g. a fresh clone orgit clean)? (Re)generate it withnpx gitnexus analyzefrom the project root. On npm 11.x, ifnpxcrashes during install (node.target is null), install once withnpm i -g gitnexus(thengitnexus analyze) or usepnpm --allow-build=@ladybugdb/core --allow-build=gitnexus --allow-build=tree-sitter dlx gitnexus@latest analyze. See #1939.
Commands
analyze — Build or refresh the index
node .gitnexus/run.cjs 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) |
--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. In Claude Code, a PostToolUse hook detects staleness after git commit and git merge and notifies the agent to run analyze — the hook does not run analyze itself, to avoid blocking the agent for up to 120s and risking KuzuDB corruption on timeout.
status — Check index freshness
node .gitnexus/run.cjs 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
node .gitnexus/run.cjs 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
node .gitnexus/run.cjs 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
node .gitnexus/run.cjs list
Lists 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
