gitnexus-cli

A command reference for GitNexus, a tool that builds a searchable index and knowledge graph of a code repository. It documents commands for analyzing, checking, cleaning, and generating a project wiki.

In plain words
What is it for?
It helps initialize GitNexus, re-index a project after major changes, inspect index status, remove index data, and generate documentation.
Why use it?
It explains how to create or refresh the index and how to check whether the stored code map is out of date.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

gitnexus-cli scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

100% identical to gitnexus-cli — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

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)
--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

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

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
