Our review
Re-indexes the GitNexus knowledge graph of a repository via the CLI, no MCP server required.
Strengths
- Fast incremental analysis for daily changes
- --force option to rebuild the entire index from scratch
- Detailed before/after stats to validate the update
- Runs fully locally with no network calls
Limitations
- Requires the repository to already be initialized with GitNexus
- Large codebases (>10k files) may take several minutes
- No MCP server available; CLI-only approach
After major refactors, merging a large PR, or when the index is reported as stale.
For minor changes that don't warrant a full reindex, or if GitNexus is not set up in the project.
Security analysis
CautionThe skill uses Bash to run npx gitnexus@latest, which fetches and executes code from npm. While the tool is described as local-only, supply chain risk exists. No destructive or exfiltration instructions are present, but caution is warranted due to external code execution.
- •Runs npx gitnexus@latest which downloads and executes remote code from npm. If the package is compromised, it could exfiltrate data or perform malicious actions.
- •The skill does not verify the integrity of the package beyond npm's default mechanisms.
Examples

GitNexus Reindex
CLI ONLY — no MCP server exists. Never use
readMcpResourcewithgitnexus://URIs.
Re-index the current repository's GitNexus knowledge graph and verify the updated stats.
When to Use
- After significant refactors (5+ files changed)
- When staleness hook reports index is behind
- After merging a large PR
- "Refresh the knowledge graph"
Workflow
Step 1: Check Current Status
Run from the repo root (the CLI auto-detects the repo from cwd):
npx gitnexus@latest status
If already current (lastCommit matches HEAD), report "Index is up to date" and stop.
Step 2: Run Indexer
npx gitnexus@latest analyze
Use --force if the index appears corrupted or if a normal analyze doesn't pick up changes:
npx gitnexus@latest analyze --force
This may take 30–120 seconds depending on codebase size.
Step 3: Verify New Index
npx gitnexus@latest status
Step 4: Report Stats
Present the updated stats:
## GitNexus Reindex Complete
| Metric | Before | After |
| ----------- | ------ | ----- |
| Nodes | ... | ... |
| Edges | ... | ... |
| Communities | ... | ... |
| Flows | ... | ... |
| Last Commit | ... | ... |
Index is now current with HEAD.
Notes
- The
analyzecommand runs locally — no network calls - KuzuDB database is stored in
.gitnexus/at the repo root - Large codebases (10k+ files) may take 2+ minutes
- The
--forceflag rebuilds from scratch; without it, incremental analysis is used
