Debugging with GitNexus

When to Use

  • "Why is this function failing?"
  • "Trace where this error comes from"
  • "Who calls this method?"
  • "This endpoint returns 500"
  • Investigating bugs, errors, or unexpected behavior

Workflow

1. gitnexus_query({query: "<error or symptom>"})            → Find related execution flows
2. gitnexus_context({name: "<suspect>"})                    → See callers/callees/processes
3. READ gitnexus://repo/{name}/process/{name}                → Trace execution flow
4. gitnexus_cypher({query: "MATCH path..."})                 → Custom traces if needed
If "Index is stale" → run npx gitnexus analyze in terminal.

Checklist

- [ ] Understand the symptom (error message, unexpected behavior)
- [ ] gitnexus_query for error text or related code
- [ ] Identify the suspect function from returned processes
- [ ] gitnexus_context to see callers and callees
- [ ] Trace execution flow via process resource if applicable
- [ ] gitnexus_cypher for custom call chain traces if needed
- [ ] Read source files to confirm root cause

Debugging Patterns

SymptomGitNexus Approach
Error messagegitnexus_query for error text → context on throw sites
Wrong return valuecontext on the function → trace callees for data flow
Intermittent failurecontext → look for external calls, async deps
Performance issuecontext → find symbols with many callers (hot paths)

Tools

gitnexus_query — find code related to error:

gitnexus_query({query: "payment validation error"})
→ Processes: CheckoutFlow, ErrorHandling
→ Symbols: validatePayment, handlePaymentError, PaymentException

gitnexus_context — full context for a suspect:

gitnexus_context({name: "validatePayment"})
→ Incoming calls: processCheckout, webhookHandler
→ Outgoing calls: verifyCard, fetchRates (external API!)
→ Processes: CheckoutFlow (step 3/7)

gitnexus_cypher — custom call chain traces:

cypher
MATCH path = (a)-[:CodeRelation {type: 'CALLS'}*1..2]->(b:Function {name: "validatePayment"})
RETURN [n IN nodes(path) | n.name] AS chain

Example: "Payment endpoint returns 500 intermittently"

1. gitnexus_query({query: "payment error handling"})
   → Processes: CheckoutFlow, ErrorHandling
   → Symbols: validatePayment, handlePaymentError
 
2. gitnexus_context({name: "validatePayment"})
   → Outgoing calls: verifyCard, fetchRates (external API!)
 
3. READ gitnexus://repo/my-app/process/CheckoutFlow
   → Step 3: validatePayment → calls fetchRates (external)
 
4. Root cause: fetchRates calls external API without proper timeout
