# 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. query({search_query: "<error or symptom>"}) → Find related execution flows 2. context({name: "<suspect>"}) → See callers/callees/processes 3. READ gitnexus://repo/{name}/process/{name} → Trace execution flow 4. cypher({statement: "MATCH path..."}) → Custom traces if needed ``` > If "Index is stale" → run `node .gitnexus/run.cjs analyze` in terminal. ## Checklist ``` - [ ] Understand the symptom (error message, unexpected behavior) - [ ] query for error text or related code - [ ] Identify the suspect function from returned processes - [ ] context to see callers and callees - [ ] Trace execution flow via process resource if applicable - [ ] cypher for custom call chain traces if needed - [ ] Read source files to confirm root cause ``` ## Debugging Patterns | Symptom | GitNexus Approach | | -------------------- | ---------------------------------------------------------- | | Error message | `query` for error text → `context` on throw sites | | Wrong return value | `context` on the function → trace callees for data flow | | Intermittent failure | `context` → look for external calls, async deps | |
