Exploring Codebases with GitNexus
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. READ gitnexus://repos → Discover indexed repos
2. READ gitnexus://repo/{name}/context → Codebase overview, check staleness
3. gitnexus_query({query: "<what you want to understand>"}) → Find related execution flows
4. gitnexus_context({name: "<symbol>"}) → Deep dive on specific symbol
5. READ gitnexus://repo/{name}/process/{name} → Trace full execution flow
If step 2 says "Index is stale" → run
npx gitnexus analyzein terminal.
Checklist
- [ ] READ gitnexus://repo/{name}/context
- [ ] gitnexus_query for the concept you want to understand
- [ ] Review returned processes (execution flows)
- [ ] gitnexus_context on key symbols for callers/callees
- [ ] READ process resource for full execution traces
- [ ] Read source files for implementation details
Resources
| Resource | What you get |
|---|---|
gitnexus://repo/{name}/context |
Stats, staleness warning (~150 tokens) |
gitnexus://repo/{name}/clusters |
All functional areas with cohesion scores (~300 tokens) |
gitnexus://repo/{name}/cluster/{name} |
Area members with file paths (~500 tokens) |
gitnexus://repo/{name}/process/{name} |
Step-by-step execution trace (~200 tokens) |
Tools
gitnexus_query — find execution flows related to a concept:
gitnexus_query({query: "payment processing"})
→ Processes: CheckoutFlow, RefundFlow, WebhookHandler
→ Symbols grouped by flow with file locations
gitnexus_context — 360-degree view of a symbol:
gitnexus_context({name: "validateUser"})
→ Incoming calls: loginHandler, apiMiddleware
→ Outgoing calls: checkToken, getUserById
→ Processes: LoginFlow (step 2/5), TokenRefresh (step 1/3)
Example: "How does payment processing work?"
1. READ gitnexus://repo/my-app/context → 918 symbols, 45 processes
2. gitnexus_query({query: "payment processing"})
→ CheckoutFlow: processPayment → validateCard → chargeStripe
→ RefundFlow: initiateRefund → calculateRefund → processRefund
3. gitnexus_context({name: "processPayment"})
→ Incoming: checkoutHandler, webhookHandler
→ Outgoing: validateCard, chargeStripe, saveTransaction
4. Read src/payments/processor.ts for implementation details
