drawio
by markdown-viewer
General-purpose diagramming tool using drawio XML format with 8900+ stencils. Best for custom diagrams requiring pixel-perfect positioning, diagrams with vendor-specific icons (AWS, Azure, Cisco), or any diagram not covered by specialized skills. Use network skill for network topology, uml skill for UML diagrams, architecture skill for layered system views. NOT for simple flowcharts (use mermaid) or data-driven charts (use vega).

calculation
by sjtu-sai-agents
"When using Mat MCP tools (mat_sg_*, mat_dpa_*, mat_doc_*): (1) Use the URL returned by a previous tool (e.g. structure_paths) as input to the next tool—do not pass only a filename when the previous step returned an https URL. (2) For long-running DPA tasks use submit_* first, then query_job_status, then get_job_results when Done—do not use synchronous tools which may timeout. (3) When polling job status, wait 30–60 seconds between queries; call get_job_results once status is Done/Success."
