From cebb98edcb26569ea4a86bcc0efb4309e09ee132 Mon Sep 17 00:00:00 2001 From: Prateek Date: Sun, 15 Feb 2026 03:08:28 +0530 Subject: [PATCH] fix: resolve dashboard GitHub API rate limiting and PR enrichment issues MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit addresses critical dashboard performance and reliability issues: **Core Issues Fixed:** 1. GitHub API rate exhaustion (~84 calls/refresh → ~7-10 calls/refresh) 2. Silent failures showing misleading PR data when rate-limited 3. Missing SessionStatus values ("done", "terminated") 4. Unnecessary enrichment of merged/closed PRs 5. No caching of API responses **Key Changes:** - Add "done" and "terminated" to SessionStatus type - Update getAttentionLevel to correctly classify terminal sessions - Skip PR enrichment for terminal sessions (merged, done, terminated) - Implement 60-second TTL cache for PR enrichment data - Handle rate limit errors gracefully with explicit "unavailable" messages - Improve default values in basicPRToDashboard (no longer misleading) - Add orchestrator terminal button to Dashboard header **Test Coverage:** - 54 new test cases across 3 test files - Tests for cache behavior, attention level classification, and serialization - All tests passing (cache: 9/9, types: 29/29, serialize: 16/16) **Performance Impact:** - 10× reduction in API calls (84 → 7-10 per refresh) - 10× improvement in rate limit exhaustion time - 60s cache prevents redundant API calls on page refresh Co-Authored-By: Claude Sonnet 4.5 --- DASHBOARD_FIXES_SUMMARY.md | 162 ++++++ packages/core/src/types.ts | 4 +- packages/web/src/app/page.tsx | 16 + packages/web/src/components/Dashboard.tsx | 10 +- packages/web/src/lib/__tests__/cache.test.ts | 93 ++++ .../web/src/lib/__tests__/serialize.test.ts | 348 +++++++++++++ packages/web/src/lib/__tests__/types.test.ts | 463 ++++++++++++++++++ packages/web/src/lib/cache.ts | 93 ++++ packages/web/src/lib/serialize.ts | 77 ++- packages/web/src/lib/types.ts | 8 +- 10 files changed, 1264 insertions(+), 10 deletions(-) create mode 100644 DASHBOARD_FIXES_SUMMARY.md create mode 100644 packages/web/src/lib/__tests__/cache.test.ts create mode 100644 packages/web/src/lib/__tests__/serialize.test.ts create mode 100644 packages/web/src/lib/__tests__/types.test.ts create mode 100644 packages/web/src/lib/cache.ts diff --git a/DASHBOARD_FIXES_SUMMARY.md b/DASHBOARD_FIXES_SUMMARY.md new file mode 100644 index 000000000..c02bb5c5b --- /dev/null +++ b/DASHBOARD_FIXES_SUMMARY.md @@ -0,0 +1,162 @@ +# Dashboard Rate Limit & Enrichment Fixes - Summary + +## Problem +The web dashboard was making ~84 GitHub API calls per refresh (6 calls × 14 sessions with PRs), quickly exhausting the GitHub GraphQL rate limit (5000 points/hour).
