gitnexus-cli

A guide to GitNexus command-line operations, where GitNexus indexes a code repository into a searchable map of files, symbols, and relationships.

In plain words
What is it for?
It is for analyzing or reanalyzing a repository, checking index status, cleaning the index, generating a wiki, and listing indexed repositories.
Why use it?
It helps an agent keep its repository map current and use it to understand a codebase instead of relying only on individual files.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 3d 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.

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.
