- 3 Aug 26 +1
No change was recorded against any check on this day. Stability & Change Management went from 23 to 27. That category is still filling its 30-day observation window: 7 days of observed history at the previous scan, 8 at this one. The score rises as the window fills, whether or not the server changes.

Dependencies 169 packages
169 packages in the resolved dependency tree · 167 deprecated · 52 stale.
The dependency tree was only partially resolved, so these counts may be incomplete.
The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability.
check_app_installed ~87
Check whether the Diagrammo desktop app is installed (macOS). Call this ONCE before choosing how to show a diagram. If installed, the preferred output is to save the .dgmo source and open that file live in the app (open_in_app with filePath) — do NOT default to an online share URL. If not installed, fall back to the online share URL.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
generate_report ~138
Generate a polished HTML report with multiple DGMO diagrams, table of contents, and optional source blocks. Opens in browser by default. For DGMO syntax call get_language_reference (e.g. color a label with a trailing color name: "Sales red").
| Name | Type | Req | Description |
|---|---|---|---|
| include_source | boolean | — | Show DGMO source in collapsible blocks |
| open | boolean | — | Open the report in the browser |
| palette | string | — | Color palette |
| sections | array | yes | Report sections, each with a diagram |
| subtitle | string | — | Optional subtitle |
| theme | string | — | Color theme |
| title | string | yes | Report title |
No output schema declared.
No examples provided.
get_examples ~76
Get example DGMO diagrams for a chart type. Returns real-world examples from the gallery that demonstrate syntax patterns. Use these as few-shot references when generating new diagrams.
| Name | Type | Req | Description |
|---|---|---|---|
| chart_type | string | — | Chart type to get examples for (e.g. "sequence", "infra", "bar"). Omit to list all available example names. |
No output schema declared.
No examples provided.
get_language_reference ~52
Get the DGMO language reference documentation. Optionally filter by chart type.
| Name | Type | Req | Description |
|---|---|---|---|
| chart_type | string | — | Optional chart type to get reference for (e.g. "sequence", "flowchart", "bar") |
No output schema declared.
No examples provided.
list_chart_types ~19
List all supported DGMO chart types with descriptions.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
open_in_app ~177
Open a DGMO diagram in the Diagrammo desktop app (macOS only). Falls back to browser preview if the app is not installed. Pass `filePath` to open a saved .dgmo file directly — the app opens THAT file, so in-app edits autosave back to it (one editable source of truth, live re-render). This is the preferred path when the app is installed: write the .dgmo source first, then open it here. Omit `filePath` for an ephemeral diagram (sends a deep link; the app creates its own copy).
| Name | Type | Req | Description |
|---|---|---|---|
| dgmo | string | yes | DGMO diagram markup |
| filePath | string | — | Absolute path to an already-saved .dgmo file. When set, the app opens this exact file for live editing instead of receiving a deep-linked copy. |
No output schema declared.
No examples provided.
preview_diagram ~105
Render one or more DGMO diagrams and open an HTML preview in the browser. Supports theme toggle and optional source display. For DGMO syntax call get_language_reference (e.g. color a label with a trailing color name: "Sales red").
| Name | Type | Req | Description |
|---|---|---|---|
| diagrams | array | yes | One or more diagrams to preview |
| include_source | boolean | — | Show DGMO source in collapsible blocks |
| palette | string | — | Color palette |
| theme | string | — | Color theme |
No output schema declared.
No examples provided.
render_diagram ~166
Render DGMO markup to SVG or PNG. Returns SVG text or base64 PNG image. When format is "png", also saves the image to a temp file and returns the path. For DGMO syntax call get_language_reference (e.g. color a label with a trailing color name: "Sales red").
| Name | Type | Req | Description |
|---|---|---|---|
| dgmo | string | yes | DGMO diagram markup. Color a label by appending a lowercase color name as the trailing token (e.g. "Sales red"); capitalize ("Red") to use a color word as literal text. |
| format | string | — | Output format |
| palette | string | — | Color palette (slate, atlas, blueprint, tidewater, nord, catppuccin, tokyo-night) |
| theme | string | — | Color theme |
No output schema declared.
No examples provided.
share_diagram ~35
Generate a shareable diagrammo.app URL for a DGMO diagram.
| Name | Type | Req | Description |
|---|---|---|---|
| dgmo | string | yes | DGMO diagram markup |
No output schema declared.
No examples provided.
suggest_chart_type ~136
Suggest the best DGMO chart type for a user's plain-English diagram request. ALWAYS CALL THIS FIRST when creating a new diagram — it prevents guessing and is the authoritative selection mechanism. Returns one of two shapes: (1) a confident pick (high/medium) with the top match's syntax, or (2) an '⚠️ ASK THE USER' directive when the choice is ambiguous or nothing matched. On an ASK-THE-USER directive, do NOT pick a type yourself — present the listed candidates to the user and wait for their choice before generating.
| Name | Type | Req | Description |
|---|---|---|---|
| prompt | string | yes | User's plain-English diagram request |
No output schema declared.
No examples provided.
validate_diagram ~52
Validate DGMO markup without rendering. Returns structured parse errors and warnings. Much faster than render_diagram — use this to check syntax before rendering.
| Name | Type | Req | Description |
|---|---|---|---|
| dgmo | string | yes | DGMO diagram markup to validate |
No output schema declared.
No examples provided.
