Pitch deck studio: reps pick the slides before every meeting

Build me an internal app my sales reps open before a customer meeting to assemble a tailored pitch deck in Google Slides for one specific HubSpot deal, instead of duplicating last quarter's file and hand editing it. This is rep driven and curation first: the rep picks the template and toggles individual slides before anything is generated. Nothing runs on a schedule or on a deal stage change.

Deal picker view. On open, resolve the signed in user to their HubSpot owner record using List Owners filtered by their email, then load that person's open deals with Search Deals, filtered to their owner id and to open pipeline stages, sorted by close date ascending. Render one card per deal showing the account name, amount, deal stage and close date. When a deal is selected, use Get Deal with associations plus Get Company and Get Contact to resolve the account name and the primary contact. Scope everything per user: a rep only ever sees deals they own.

Template and slide curation view. Once a deal is picked, list the master templates in a configured Drive template folder with Google Drive List Files, querying for presentations whose parent is that folder. When the rep picks a template, read its slides with Google Slides Get Slides and render them in order as a thumbnail strip using Get Page Thumbnail for each slide. Put a checkbox on every optional slide so the rep keeps the industry case study that fits, drops the two that do not, and decides whether to include the pricing tier slide and the security appendix. Slides marked required in app configuration render locked and checked. Show the expected placeholder tokens on screen next to the strip, {{Company}}, {{Contact}}, {{Amount}} and {{CloseDate}}, so whoever maintains the templates knows exactly what gets substituted.

Build my deck button, backed by an embedded background agent. Pressing it kicks off a background agent for that deal, that template and that slide selection. The agent finds or creates the deal's folder in Drive with List Files and Create Folder, copies the template into it with Copy File and names the copy after the account and the date, deletes every unchecked slide with Google Slides DeleteObject, fills the placeholders with ReplaceAllText using the real deal values, fixes the ordering afterwards with UpdateSlidesPosition, then writes the result back to the CRM: HubSpot Create Note on the deal with the deck link and the list of slides included, and HubSpot Update Deal to stamp the deck URL property.

Handle the atomicity of Google Slides edits carefully. A batch of slide edits is applied all or nothing, so one failed slide deletion rolls the whole batch back. Have the agent re-read the copied presentation and verify the slide ids before deleting, retry once with any stale ids removed, and if it still fails, leave the copy in place, mark the build failed with a readable reason, and surface that in the app rather than leaving a half built deck behind.

Build history. Each deal keeps a decks built history persisted in the app: deck name, link, a thumbnail of the title slide, which optional slides were included, who built it and the timestamp. Show it on the deal detail view, newest first, so a rep can reopen what they sent last time. History is scoped per user like the deal list.

Handle the empty and in progress states plainly: no open deals for this rep, no templates in the folder, a template with no slides, and a build still running with a progress indicator that resolves into the finished deck link.
