## What Adds a new admin-only **PR Insights** page for the `/agents` analytics view — a dashboard for engineering leaders to understand code shipped by AI agents. ### Backend - `GET /api/v2/chats/insights/pull-requests` — admin-only endpoint - 4 SQL queries in `chatinsights.sql` aggregating `chat_diff_statuses` joined with chat cost data (via root chat tree rollup) - Runs 5 parallel DB queries: current summary, previous summary (for trends), time series, per-model breakdown, recent PRs - SDK types auto-generate to TypeScript ### Frontend (`PRInsightsView`) - **Stat cards**: PRs created, Merged, Merge rate, Lines shipped, Cost/merged PR — with trend badges comparing to previous period - **Activity chart**: Stacked area chart (created/merged/closed) using git color tokens (`git-added-bright`, `git-merged-bright`, `git-deleted-bright`) - **Model performance table**: Per-model PR counts, inline merge rate bars, diff stats, cost breakdown - **Recent PRs table**: Status badges, review state icons, author info, external links - **Time range filter**: 7d/14d/30d/90d button group - **4 Storybook stories**: Default, HighPerformance, LowVolume, NoPRs ### Data source All PR data comes from the existing `chat_diff_statuses` table (populated by the `gitsync.Worker` background job that polls GitHub every 120s). No new data collection required. ### Screenshot View in Storybook: `pages/AgentsPage/PRInsightsView`
