feat(analytics): per-agent cost breakdown and clickable Gantt timeline#363
Merged
Conversation
…eline - Extract sub-agent token usage by matching tool_use IDs against agent-<id>.meta.json - Enrich each agent dispatch with costUSD and token breakdown from its transcript - Add clickable timeline bars; side panel shows cost, tokens, duration, tool calls per agent - Scope Gantt scale to agent activity window so bars fill the track proportionally - Agent-only bars in Gantt (skills/commands removed per spec); proportional wall-clock scaling - Fix: costUSD omitted when no model has a pricing entry (was incorrectly set to $0) - Fix: agent description removed from dispatch name fallback (prevented info leaking into reports) - Fix: tl-bar min-width 28px; bar left uses calc(min(..., 100%-28px)) to prevent clip at track edge - Fix: tl-dur column narrowed to 72px to reduce gap between bars and duration label Generated with AI Co-Authored-By: codemie-ai <codemie.ai@gmail.com>
