14 tools

• render_chart

  Use this when the user wants to preview or generate a chart. Validate each generated or changed chart input once before rendering, saving, or updating. Do not revalidate unchanged input; a successful render preflights it for later saves or updates. Errors block; warnings require…

• save_chart

  Use this when the user wants to permanently save and publish a Szum chart document. Validate each generated or changed chart input once before rendering, saving, or updating. Do not revalidate unchanged input; a successful render preflights it for later saves or updates. Errors…

• list_charts

  Use this when the user wants to find charts in their saved library. Returns paginated metadata and URLs, not chart documents; requires authentication. Draft-only editor charts have publishedAt null, hasDraft true, and sizeBytes 0 because sizeBytes measures only the stored…

• get_chart

  Use this when the user identifies a saved chart by id and wants to view it or retrieve its metadata and URLs. Displays the published chart when available and does not return its document; requires authentication.

• get_chart_document

  Use this when the user identifies a saved chart by id and needs its complete published Szum document for inspection or reuse. Does not return a newer editor draft; requires authentication.

• get_preview_state

  Use this when the Szum chart App needs to restore a rendered preview as its current transient or saved view. It is read-only, owner-scoped when authenticated, and hidden from the model.

• update_chart

  Use this when the user wants to replace and publish a saved chart's document while keeping its id and URLs. Validate each generated or changed chart input once before rendering, saving, or updating. Do not revalidate unchanged input; a successful render preflights it for later…

• rename_chart

  Use this when the user wants to change a saved chart's library title without changing its document, publication state, or public URLs; requires authentication.

• delete_chart

  Use this when the user explicitly wants to permanently delete one saved chart. Deletion cannot be undone, and retrying an already completed deletion succeeds; requires authentication.

• list_themes

  Use this when choosing a visual theme for a chart. Returns every built-in theme with guidance on where each works best and, when signed in, the workspace's shared themes.

• validate_chart

  Use this when a chart request or document will be rendered, saved, or updated. Validate each generated or changed chart input once before rendering, saving, or updating. Do not revalidate unchanged input; a successful render preflights it for later saves or updates. Errors…

• list_chart_types

  Use this when choosing a chart family. Returns every current chart type with its shared and family-specific fields.

• get_examples

  Get complete Szum documents for validation, rendering, or saving, with guidance on when to use each pattern. No filters returns one starter per chart type. Any filter searches the complete catalog; all supplied filters intersect. Most data is illustrative; the Vinyl waterfall…

• get_schema

  Use this before authoring an unfamiliar field instead of probing validate_chart for errors. Returns the JSON Schema for the whole Szum document, covering config, data, presentation, size, and output, with every referenced definition included. Pass chart_type to keep only that…
