Force-directed graph visualization for agent teams. Package: @claude-teams/agent-graph (isolated workspace package) - Space theme: bloom, particles, hex grid, depth stars - Members as hexagonal nodes with breathing glow - Tasks as pill cards in kanban columns (todo/wip/done/review/approved) per owner - Message particles along edges (real-time only) - Deterministic layout, Figma-style pan, scroll/pinch zoom - Clean Architecture: ports/adapters/strategies, ES #private classes Integration: features/agent-graph/ (adapter + overlay + tab) - Full-screen overlay (Cmd+Shift+G) + Pin as Tab - Graph button in Team section header - Frustum culling, zero per-frame allocations, adaptive fps - Performance overlay via ?perf query param Also: CI runs on all PR branches, features/CLAUDE.md architecture guide
