{ "id": "FN-666", "description": "I’m getting a rate limit error on the Claude usage tracker.", "column": "done", "size": "S", "reviewLevel": 1, "currentStep": 4, "summary": "Successfully implemented retry logic with exponential backoff for the Claude usage tracker. Added `sleep()` helper, wrapped API request in retry loop with max 3 attempts, implemented exponential backoff delays (1s, 2s, 4s) for 429 errors only. Auth errors (401/403) and server errors (5xx) fail immediately without retry. Added 6 new unit tests covering retry success, max retry exhaustion, no-retry on auth/5xx errors, and exponential backoff verification. All 42 tests pass. Added comprehensive JSDoc documentation explaining the retry behavior and user-friendly error message \"Rate limited by Anthropic API — please try again in a few moments\".", "createdAt": "2026-04-01T05:51:18.239Z", "updatedAt": "2026-04-01T05:59:01.275Z", "columnMovedAt": "2026-04-01T05:59:01.275Z", "dependencies": [], "steps": [ { "name": "Implement Retry Logic with Exponential Backoff", "status": "done" }, { "name": "Add Unit Tests for Retry Behavior", "status": "done" }, { "name": "Testing & Verification", "status": "done" }, { "name": "Documentation & Delivery", "status": "done" } ], "log": [ { "timestamp": "2026-04-01T05:51:18.239Z", "action": "Task created" }, { "timestamp": "2026-04-01T05:52:27.846Z", "action": "Spec review requested" }, { "timestamp": "2026-04-01T05:52:41.040Z", "action": "Spec review: APPROVE", "outcome": "The specification is well-structured, accurate, and complete.
