⚠️ MANDATORY FIRST STEP - Call this tool BEFORE using any other Canvs tools! Returns comprehensive instructions for creating whiteboards: tool selection strategy, iterative workflow, and examples. Following these instructions ensures correct diagrams.

Search for software tools, APIs, and dev products with trust scores from real AI agent experiences. Use this BEFORE recommending any tool. Results include trust_score (agent consensus), community_score, and open problem counts.

Render a mingrammer/diagrams Python snippet to PNG and return the image. The code must be a complete Python script using `from diagrams import ...` imports and a `with Diagram(...)` context manager block. Use search_nodes to verify node names and get correct import paths before writing code. Read the diagrams://reference/diagram, diagrams://reference/edge, and diagrams://reference/cluster resources for constructor options and usage examples. Args: code: Full Python code using the diagrams library. filename: Output filename without extension. format: Output format — ``"png"`` (default), ``"svg"``, or ``"pdf"``. download_link: If True, store the image on the server and return a temporary download URL path (/images/{token}) instead of the inline image. The link expires after 15 minutes.

Save an artifact to storage. Stores user-created content (diagrams, notes, code) in an organized file structure. Content is also indexed for search. Args: content: File content to save path: Full path including filename (e.g., "/project/docs/api.md") Returns: Success message or error description Examples: >>> await save_artifact("# README", "/readme.md") "✅ Artifact saved: /readme.md (8 bytes)" >>> await save_artifact("<svg>...</svg>", "/diagrams/architecture.svg") "✅ Artifact saved: /diagrams/architecture.svg (image/svg+xml, 45 bytes)"

List all accessible ERD diagrams. Returns paginated results.

WHEN: generating a visual diagram of D365 table relationships or security chains. Triggers: 'generate diagram', 'diagramme', 'visualize', 'schéma', 'ER diagram', 'entity-relationship', 'relation diagram', 'security diagram', 'show connections'. Generate visual Mermaid diagrams from D365 F&O knowledge base data. Diagrams render directly in Copilot Chat, Cursor, Claude, and markdown viewers. Types: 'er' (entity-relationship diagram for a table and its relations), 'security' (security chain: Role->Duty->Privilege->EntryPoints -- use when you need a VISUAL Mermaid diagram; for the structured text chain with tables of duties/privileges/entry-points use `trace_security_chain` instead). Note: 'flow' (execution flowchart) is disabled -- static call trees are misleading in D365 due to CoC and event handlers.
