+# Story 300: Show token cost badge on pipeline board work items
+
+## User Story
+
+As a project owner viewing the pipeline board, I want to see the total token cost for each work item displayed as a badge, so that I can quickly spot expensive stories at a glance.
+
+## Acceptance Criteria
+
+- [ ] Each work item on the pipeline board shows its total cost in USD as a small badge
+- [ ] Cost is fetched from the token_usage.jsonl data via a new API endpoint
+- [ ] Items with no recorded usage show no badge (not $0.00)
+- [ ] Cost updates when the pipeline refreshes (e.g. after an agent completes)
+- [ ] Expanded work item detail panel shows per-agent cost breakdown (coder, QA, mergemaster) with token counts
+
+## Out of Scope
+
+- TBD
