Programmatic canvas toolkit for creating, editing, and refining Excalidraw diagrams via MCP tools with real-time canvas sync. Use when an agent needs to (1) draw or lay out diagrams on a live canvas, (2) iteratively refine diagrams using describe_scene and get_canvas_screenshot to see its own work, (3) export/import .excalidraw files or PNG/SVG images, (4) save/restore canvas snapshots, (5) convert Mermaid to Excalidraw, or (6) perform element-level CRUD, alignment, distribution, grouping, duplication, and locking. Requires a running canvas server (EXPRESS_SERVER_URL, default http://127.0.0.1:3000).

Analyze local AI-agent session histories and report usage counts for agent skills, tools, commands, or MCP actions across sessions. Use for requests about skill rankings, top skills used last week, tool usage, recent-session comparisons, agent-specific usage, or exports from Codex, Claude Code, and other compatible JSON or JSONL agent-history exports. Read-only.
