Tools

• 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.

  shallow
• 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 config; requires authentication.

  shallow
• get_chart_config

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

  shallow
• get_examples

  Use this when the model needs current, ready-to-use Szum chart configs or preferred semantic patterns. Optionally filters examples by mark type.

  shallow
• 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.

  shallow
• list_charts

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

  shallow
• list_marks

  Use this when choosing or configuring chart mark types. Returns every available mark with its properties and defaults.

  shallow
• list_themes

  Use this when choosing a visual theme for a chart. Returns every available theme and guidance on where each works best.

  shallow
• rename_chart

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

  shallow
• render_chart

  Use this when the user wants to preview or generate a chart. Validate each generated or changed config 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 explicit user approval for the exact config. Suggestions do not block. Replace the complete config with suggestedConfig and revalidate before repair. Stores a 1 hour preview and returns public image URLs. Authenticated previews use the account's render allowance, and each image produced from a returned URL is another render. Anonymous previews are complimentary; their images use the anonymous image allowance.

  shallow
• save_chart

  Use this when the user wants to permanently save and publish a chart from a Szum config. Validate each generated or changed config 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 explicit user approval for the exact config. Suggestions do not block. Replace the complete config with suggestedConfig and revalidate before repair. Supply one idempotencyKey per intended chart and reuse it for retries. Returns permanent public Image and Embed URLs plus Edit and Studio links; requires authentication and saved-chart storage.

  shallow
• update_chart

  Use this when the user wants to replace and publish a saved chart's config while keeping its id and URLs. Validate each generated or changed config 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 explicit user approval for the exact config. Suggestions do not block. Replace the complete config with suggestedConfig and revalidate before repair. Refuses charts with unpublished editor changes; requires authentication and saved-chart storage.

  shallow
• validate_chart

  Use this when a chart config will be rendered, saved, or updated. Validate each generated or changed config 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 explicit user approval for the exact config. Suggestions do not block. Replace the complete config with suggestedConfig and revalidate before repair. Read-only, free, and fast.
