Update a Rootr presentation (theme/slides/config)
rootr_update_presentationUpdate a presentation's theme, config, or replace all slides using a merge patch. Existing content stays unless explicitly overridden.
Instructions
Merge-patch a Rootr (루터) PRESENTATION: update theme and/or config, or REPLACE THE WHOLE slides array (if you pass slides, it replaces every existing slide — call rootr_read_presentation first and resend slides you want to keep, or use rootr_append_presentation_slides / rootr_update_presentation_slide instead for incremental changes). Authoring guide: give each slide ONE assertion-style title (a claim, e.g. "Latency dropped 40% after the cache fix" — not a topic label like "Latency"), plus blocks[] (bullet-like {id, heading?, body?, icon?} items) and, where useful, a diagram ({type:"mermaid", code}) or images. Canvas is 16:9 (1280x720). Meaning must live in TEXT — title/blocks[].heading/blocks[].body/notes are what auto-connects into the knowledge graph; diagrams/code/html and the image pixels themselves are visual-only and are NOT indexed, so never put facts ONLY in a diagram or picture.
Images: image is the single primary/background image (cover, section, full-bleed); images[] holds additional inserted images placed on the slide. Each image is {id?, src?, alt?, placement?, prompt?, x?, y?, w?, h?}. Set src to an uploaded file URL (upload via POST /v1/attachments/upload, then use /api/v1/attachments/{id}/raw), an https URL, or a data: URI — you cannot upload the file bytes through these MCP tools, only reference the resulting URL. To get a REAL image, call rootr_generate_image with an English prompt (say "no text"), then put the returned url into the slide image's src; rootr_remove_image_background cuts out an image's background. placement is a layout hint ("full"|"right"|"top"|...); x/y/w/h give freeform PPT-style placement in 1280x720 canvas coords. ALWAYS add an alt caption to every image — alt text is part of the graph text spine, so a captioned image connects into the knowledge graph while an uncaptioned one does not.
Use kind to mark each slide's role: "cover" (deck title slide), "section" (chapter divider), "content" (body slide, the default), "closing" (last slide / call to action).
Page numbers: "content" and "section" slides automatically show a page number that follows the slide order (it re-numbers itself when slides are reordered), so you do NOT set it yourself. "cover"/"closing" have none by design.
