Exploring Codebases with GitNexus
IMPORTANT — How to use GitNexus: GitNexus is a standalone CLI tool. Run it directly
via gitnexus <command> in the Bash tool. Do NOT use mcpl call gitnexus ... or
npx gitnexus ... — gitnexus is installed globally and invoked by name.
Multi-repo note: Always pass --repo <name> to every command that operates on a
specific repo to avoid "multiple repositories" errors.
When to Use
- "How does authentication work?"
- "What's the project structure?"
- "Show me the main components"
- "Where is the database logic?"
- Understanding code you haven't seen before
Workflow
1. gitnexus status → Check index freshness
2. gitnexus query "<what you want>" --repo <name> → Find related execution flows
3. gitnexus context "<symbol>" --repo <name> → Deep dive on specific symbol
4. Read source files from the output for implementation details
If step 1 says "Index is stale" → run gitnexus analyze in terminal.
Checklist
- [ ] gitnexus status — check index freshness
- [ ] gitnexus query for the concept you want to understand
- [ ] Review returned processes (execution flows)
- [ ] gitnexus context on key symbols for callers/callees
- [ ] Read source files for implementation details
CLI Commands Reference
All commands are run directly via the Bash tool. Do not use mcpl or npx.
| Command | What it gives you | Example |
|---|
gitnexus query "<concept>" --repo <name> | Process-grouped execution flows related to a concept | gitnexus query "payment processing" --repo <name> |
gitnexus context "<symbol>" --repo <name> | 360-degree symbol view — callers, callees, processes | gitnexus context "validateUser" --repo <name> |
gitnexus status | Index freshness check | gitnexus status |
Example: "How does payment processing work?"
1. gitnexus status → 918 symbols, 45 processes
2. gitnexus query "payment processing" --repo my-app
→ CheckoutFlow: processPayment → validateCard → chargeStripe
→ RefundFlow: initiateRefund → calculateRefund → processRefund
3. gitnexus context "processPayment" --repo my-app
→ Incoming: checkoutHandler, webhookHandler
→ Outgoing: validateCard, chargeStripe, saveTransaction
4. Read src/payments/processor.ts for implementation details
