generate_diagram_from_asciiInspect

Convert an ASCII art diagram into a polished visual diagram. Use this tool when the user has an existing ASCII art representation of a system, flow, or architecture and wants it rendered as a proper diagram. Accepts box-drawing characters, arrow representations (-->, ==>), and plain text layouts. Returns a link to view and edit the generated diagram in the browser.

ParametersJSON Schema

Name	Required	Description
`prompt`	No	Additional instruction for rendering. Example: "Use a dark theme and add icons"
`content`	Yes	Raw ASCII art diagram to convert into a polished visual diagram. Include the full ASCII art as-is, with box-drawing characters, arrows, or plain text layout. Example: +--------+ +--------+ \| Client \| --> \| Server \| +--------+ +--------+
`diagramType`	No	Preferred diagram type. Leave blank to let the AI infer from the ASCII layout.
`isIconEnabled`	No	Set to true when the user asks to include icons in the diagram.

generate_diagram_from_imageInspect

Convert an image (whiteboard photo, screenshot, hand-drawn sketch) into a clean diagram. Use this tool when the user provides an image URL or base64-encoded image and wants it converted to a proper software engineering diagram. Accepts public image URLs or base64 data URIs (data:image/...;base64,...). Returns a link to view and edit the generated diagram in the browser.

ParametersJSON Schema

Name	Required	Description
`prompt`	No	Instruction describing what to extract or how to render the diagram. Example: "Convert this whiteboard photo into a clean sequence diagram"
`content`	Yes	Either a public image URL or a base64 data URI of the image to convert. Supported formats: JPEG, PNG, GIF, WebP. For a URL: 'https://example.com/whiteboard.png'. For a data URI: 'data:image/png;base64,iVBORw0KGgo...'
`diagramType`	No	Preferred output diagram type. Leave blank to let the AI decide based on the image content.
`isIconEnabled`	No	Set to true when the user asks to include icons in the diagram.

generate_diagram_from_jsonInspect

Generate a diagram from a JSON structure. Use this tool when the user wants to visualise JSON data such as API responses, database schemas, dependency trees, configuration files, or any structured data. Pass the raw JSON string as content. Returns a link to view and edit the generated diagram in the browser.

ParametersJSON Schema

Name	Required	Description
`prompt`	No	Instruction for how to interpret or render the JSON. Example: "Show as an entity relationship diagram with cardinality labels"
`content`	Yes	A JSON string representing the structure to visualise. This can be API response data, a database schema, a config file, dependency tree, or any other structured JSON. Example: '{"users": [{"id": 1, "orders": [{"id": 101}]}]}'
`diagramType`	No	Preferred diagram type. Defaults to 'erd' for schemas and 'flowchart' for other JSON.
`isIconEnabled`	No	Set to true when the user asks to include icons in the diagram.

generate_diagram_from_mermaidInspect

Convert a Mermaid diagram definition into a D2 diagram and return a PNG image. Use this tool when the user has existing Mermaid code (flowchart, sequenceDiagram, erDiagram, etc.) and wants it converted to D2 or rendered as an image. Pass the Mermaid source as content. Returns a link to view and edit the generated diagram in the browser.

ParametersJSON Schema

Name	Required	Description
`prompt`	No	Optional instruction for layout or styling of the converted diagram.
`content`	Yes	A Mermaid diagram definition to convert to D2. Pass the raw Mermaid source (e.g. flowchart, sequenceDiagram, erDiagram). Example: "flowchart LR A --> B --> C"
`diagramType`	No	Preferred diagram type for the converted D2 output.
`isIconEnabled`	No	Set to true when the user asks to include icons in the diagram.

generate_diagram_from_textInspect

Generate a software engineering diagram from a natural language description. Use this tool when: the user asks to 'create a diagram', 'show me a flowchart', 'visualise the architecture', uses the keyword 'adm' or 'ai diagram maker', or asks for any visual representation of code, systems, processes or data flows. Supported diagram types: flowchart, sequence, ERD, system architecture, network architecture, UML, mindmap, workflow. Returns a link to view and edit the generated diagram in the browser.

ParametersJSON Schema

Name	Required	Description
`prompt`	No	Additional styling or layout instruction. Example: "Use left-to-right layout with pastel colors"
`content`	Yes	Natural language description of the diagram to generate. Be descriptive — include components, relationships, data flows, etc. Example: "Create a microservices architecture with API gateway, auth service, user service, and PostgreSQL database"
`diagramType`	No	Preferred diagram type. Leave blank to let the AI infer the best type from your description.
`isIconEnabled`	No	Set to true when the user asks to include icons in the diagram.
