Text was only the beginning. Welcome to the multimodal era, where AI understands the world through images, videos, and continuous streams of information. In this video, we'll explore the multimodal capabilities of Google AI Studio, like generating rich content from diverse inputs, understanding vast amounts of information, and even reacting in real time. So, let's get started with long context. Google AI Studio and Gemini excels in this area. Long context refers to a model's ability to process and understand a very large amount of information within a single prompt or conversation. An AI model's context window is sort of like its short-term memory. It's measured in tokens, which are roughly words or parts of words. This window determines how much information the model can consider at once when generating a response. Now historically, the amount of tokens a large language model could handle was limited. But new Gemini models come with larger context windows and can handle 1 million or even 2 million tokens. To put that into perspective, 1 million tokens equals approximately 50,000 lines of code, all the text messages you have sent in the last 5 years, 8 average length English novels, or transcripts of over 200 average length podcast episodes. So it goes without saying that these models can handle a lot. Not long ago, long context video capabilities were relatively limited due to the lack of accessibility of the medium itself. Now with new Gemini models, long context text capabilities translate to the ability to reason and answer questions about multimodal inputs with sustained performance. Some emerging and standard use cases for video long context include: question and answer, memory, meaning the ability of a model to retain and recall information, captions, recommendation systems by enriching existing metadata with new multimodal understanding, customization by analyzing content and then removing parts that are not relevant to the viewer, content moderation, and real-time processing. Now if you've used Gemini before, you might know that it has several different talents. This includes both images and videos. Imagen is fantastic for generating photorealistic and artistic images. And Gemini Flash experiments can mix images right into text responses. The usual prompt advice applies: be descriptive. And here's how to level up: Paint the picture. Don't just say dog, say a fluffy golden retriever puppy sitting in a field of daisies, soft morning light, shallow depth of field. Think subject, setting, style, and even camera details. Need text? Imagen can add text to images. Keep it short and sweet like a coffee cup with the text Good Morning! written neatly. Exclude stuff. Use negative prompts to tell it what not to include, negativePrompt: blurry, low quality. Google AI Studio can also generate video clips. And this is where things get really exciting. Veo is Google's powerful video generator. You can type a description and get a short video clip, or even bring a still image to life. Whether you're generating from text or from images, be a director. Describe the scene: who or what is in it, what they're doing, the camera movement, and the vibe, like a cinematic moody lighting. Before jumping into a demo, let's explore one more amazing capability of Google AI Studio: real-time streaming. This is where things go from 'Wow, that's cool' to 'Whoa, is this the future?'. You can even point your camera or even stream your screen directly into Google AI Studio, and the model understands and responds as it happens. It's not just analyzing the past, it's reacting to the present. It's like, instead of showing your friend a recording of you building that next level LEGO castle, you could ask, 'Hey Gemini, what piece should I look for next?' while you're still building, and Gemini comes back with an answer: 'Look for six 2x4 gray bricks. Let me know when you find and place them, and I'll help you with the next step.' This isn't just about feeding the AI information anymore. It's about having a dynamic conversation with it using live video and audio. It turns Google AI Studio from just an analysis tool into a potential real-time collaborator or an instant feedback machine. This streaming capability changes the game for how we interact with AI. Okay, so enough talk about these amazing capabilities. So here we are in Google AI Studio, and we are going to add a relatively long video, and then prompt the model to perform a few specific tasks. So let's click the plus icon in the chat prompt interface, and this is coming from YouTube. So let's click that YouTube video, paste the video URL here, and click Save. Now let's design our prompt and keep it simple for now, and ask the model to provide a detailed summary, including main points, supporting evidence, and any conclusions. And let's run this. Okay, and let's be patient. It does have to watch through a 22-minute video. And now we have some results. Okay wow, just as instructed, the model provided a detailed summary, very detailed, with main points, evidence, and some conclusions. This output is structured very nicely as well. And the model essentially watched the 22-minute video in about a minute. Okay, so let's switch gears and check out another capability. And this will be a nice segue into the next video in this course, where you will learn to prototype your own app. So let's click the Build tab, and this will pull up an interface with demo apps. More on this in the next video, so stay tuned. But for now, we're going to show some of the spatial understanding and object detection capabilities of Google AI Studio. Gemini models have a strong understanding of objects and their visual representations. So this is essentially a prototype of an app that can detect objects in an image. In this simple example, the prompt is asking for the position of the items in the image and for the model to add 2D bounding boxes around them. When we send this to the model, we can see that it's added 2D bounding boxes and labeled what each item is. And if we click the code icon, we can see the behind the scenes code for what's actually making this work. And this is something you can use in your own applications to leverage the power of Gemini models. In the next video, we'll continue this discussion and dive deeper into the world of app prototyping with Google AI Studio.

Neither touches the player hook, chat grounding, the pack schema, or adds a Runbook tab. This cut stays additive (new files, one new tab, new optional props) to keep the eventual merge mechanical. + +## 1. Goal & Scope +* **Objective:** Turn the Deliverables pane from a static reference into a 1-of-N step runner whose steps are temporally anchored to the video, with a Step 0 prerequisites checklist, a Full Runbook Markdown mode, and chat grounded to the active step. +* **Context:** Pollen Robotics Reachy Mini assembly guide as the UX benchmark. Zero-Sim rule: never invent evidence — a step with no pack-derived anchor shows `null` and disables seek instead of guessing. +* **Scope:** + * `apps/web/src/lib/runbook-steps.ts` — new pure compiler: pack (+ linked SOP) → `Runbook { prerequisites, steps[] }`, markdown renderer, time → step lookup, hash helpers. + * `apps/web/src/lib/video-pack-types.ts`, `video-pack.ts`, `video-pack-extractor.ts` — optional `start_s/end_s` on requirements and action items (prompt + parser). No `VIDEO_PACK_STRUCTURE_SCHEMA_VERSION` bump (would force paid re-extraction of every stored pack). + * `apps/web/src/lib/emit-video-pack.ts` — pass `code_snippets` through to the client citation. + * `apps/web/src/lib/use-youtube-player.ts` — `seekTo(seconds, { autoplay })` cue-only option (default unchanged). + * `apps/web/src/lib/chat-pack-grounding.ts`, `api/chat/route.ts` — validated `step` context → windowed transcript + step block in the system prompt. + * `apps/web/src/components/studio/StepRunner.tsx`, `StudioRunbookPane.tsx` — stepper, step card, prerequisites, markdown mode. + * `apps/web/src/components/studio/StudioIdeOutput.tsx` — new `Runbook` tab (first, default when present) via one optional prop. + * `apps/web/src/components/studio/StudioIdeChat.tsx` — optional `stepContext` chip + body field. + * `apps/web/src/components/OneLoopStudio.tsx` — compile runbook, wire player, progress persistence, chat re-grounding. + * `apps/web/src/store/dashboard-types.ts` — optional `runbookProgress` on `Video`. + * `apps/web/src/lib/action-surface.ts` — `RUNBOOK.md` in the ship package. + * *Initial check:* `sopStepsFromPack` / `deriveSopTimestampFromPackFields` (emit-app-builder-sandbox.ts) already derive honest SOP seek times; the token helpers are exported and reused rather than duplicated. `renderDeployMarkdown` is the markdown precedent. No new dependencies. + +### Hypotheses considered +1. **Prompt-only:** ask Gemini for `timestamp_range` on every requirement and rely on it. Rejected as the sole path: stored packs would need a paid re-extract, and model-reported ranges still need an honest fallback. +2. **Client-only derivation:** anchor steps from chapters/segments/visuals/grounded-spec citations already on the pack. Works for every stored pack today; coarse (chapter-level) when text overlap is weak. +3. **Both (chosen):** additive optional `start_s/end_s` in the extractor for new packs, plus deterministic derivation with explicit `anchor` provenance for everything else. Unanchored steps stay `timestamp_range: null`. + +## 2. Execution Plan +- [x] RED: `runbook-steps.test.ts` on the real `pBsT6v-ciO8` pack slice (ids, anchors, kinds, verification, prerequisites, markdown, time lookup, hash). First run: 13/16 passed; the 3 failures were the range-extension rule producing `[268, 290.5]` for REQ-03 (segments 35–36 continue the outreach step) — verified against the segment text and pinned. +- [x] GREEN: `runbook-steps.ts` (16/16). +- [x] Schema: optional `start_s/end_s` (types, zod, parser, both prompts) + `code_snippets` passthrough; tests. +- [x] Player hook: `seekTo(seconds, { autoplay })`; jsdom hook test with stubbed IFrame API. +- [x] Chat: `parseChatStepContext` (zod, strict, bounded) + windowed prompt; grounding + route tests (400 `step_context_invalid` / `step_context_requires_pack`). +- [x] UI: `StepRunner`, `StudioRunbookPane`, Runbook tab (first, default when present), chat chip; 9 jsdom tests. +- [x] Wire `OneLoopStudio`; `RUNBOOK.md` export; `Video.runbookProgress`; 5 integration tests. +- [x] Verify: focused Vitest, `tsc --noEmit`, eslint on touched files, full web suite, `next build`, live route round-trip, headed browser walkthrough. + +## 3. Definition of Done (Success Verification) +* **Expected Outcome:** With a stored pack selected, Deliverables opens on **Runbook → Step-by-Step Runner**. Step 0 is a prerequisites checklist from `stack.tools`/stack checks. `Next` advances `Step n of N`, scrolls the runner to top, writes `#step-n`, seeks the player to the step's anchored start (cue-only when autoplay is off, pauses at range end when on), and the chat chip reads "Grounded to Step n". Steps without pack evidence show "No verified timestamp" and never seek. `Full Runbook Markdown` shows/copies/downloads `RUNBOOK.md`. +* **Verification Method:** + * `cd apps/web && npx vitest run src/lib/__tests__/runbook-steps.test.ts src/components/studio/__tests__/StepRunner.test.tsx src/components/__tests__/OneLoopStudio.runbook.test.tsx src/lib/__tests__/chat-pack-grounding.test.ts src/app/api/__tests__/chat-pack-grounding-route.test.ts src/lib/__tests__/use-youtube-player.test.ts src/lib/__tests__/emit-video-pack.test.ts src/lib/__tests__/video-pack-structure.test.ts src/lib/__tests__/action-surface.test.ts` + * `npx tsc --noEmit` · `npx eslint ` · `npx vitest run` (full web suite) +* **Proof Artifact (2026-10-17, head of `cursor/studio-step-runner-3c1b`):** + * Focused Vitest (listed above): all green — `runbook-steps` 16, `StepRunner` 9, `OneLoopStudio.runbook` 5, grounding 11, route 6, hook 3, plus extractor/emit/structure/action-surface additions. + * Full web suite: **173 files, 1563 passed, 28 skipped** (all pre-existing opt-ins: Redis-gated G.A.T.E. cases, one live clip probe). + * `npx tsc --noEmit` exit 0 · `npx eslint` on every touched file exit 0 · `npx next build` exit 0. + * Live route round-trip (one-off test outside the repo, real `POST /api/chat`, memory pack store seeded with the live pack, real Vercel AI Gateway call): HTTP 200 in 1086 ms, answer *"The speaker says, 'Step one: search up SeaDance 2.5, find any provider,' at 4:07–4:14 in the video."* — the step's anchored range and quote from the windowed transcript. + * Headed Chrome walkthrough on the production build with the live pack seeded in localStorage: Runbook tab default; Step 0 lists 3 tools; Next → `#step-1`, `4:07–4:14 · Transcript segment`, chat chip "Grounded to Step 1 of 7", keyframe `/api/video/pack/frames/pBsT6v-ciO8/249`; Step 3 shows `interface SpecAdPitch`; completion persisted to `runbookProgress`; RUNBOOK.md view + `download="RUNBOOK.md"`; Troubleshoot focused the composer with "Paste the error or ask about Step 3…".

Live Gemini extraction of the new optional `start_s/end_s` fields was not exercised (no `GOOGLE_API_KEY`); the parser path is unit-tested. + +## 4. Post-Task Reflection +* **What was done:** Added a pure runbook compiler that anchors pack requirements / action items (or the linked SOP) to the video timeline from pack evidence only, with provenance per step and `null` when none exists; a Step Runner (stepper, Step 0 prerequisites, per-step action card, cue/clip playback, hash + scroll, local completion notes) and a RUNBOOK.md reference mode inside Deliverables; step-scoped chat grounding end to end (client chip → validated `step` field → windowed system prompt); optional extractor time ranges and client-visible code snippets; `RUNBOOK.md` in Export. +* **Why it was needed:** The pipeline already produced time-anchored evidence, but the Deliverables pane showed it as static text, so the "active execution copilot" intent was unmet at the presentation layer (§0). The runner closes that gap without inventing evidence and without forcing a paid re-extract of stored packs. +* **How it was tested:** RED→GREEN Vitest on the live `pBsT6v-ciO8` pack slice, jsdom component/integration tests, type-check, lint, production build, one real gateway round-trip through the real route, and a recorded headed-browser walkthrough of the production build. + +## 5. Review update (2026-10-28) + +The test fixture now uses a freshly fetched, source-bound saved pack for `auJzb1D-fag`, in line with the repository fixture rule. The earlier `pBsT6v-ciO8` results above record the original implementation test and remain historical evidence. Review fixes also bind chat prompts to the server-compiled step, reset chat history on step changes, preserve initial step links, restore grounded acceptance checks with explicit timing, bound step IDs, retain actions with malformed optional timing, and reset clip pause state when seeking again. The current full web suite passed: 174 files, 1571 tests passed, 28 skipped; lint, type check, and production build passed locally. Hosted checks and reviewer state remain separate gates. diff --git a/apps/web/src/lib/use-youtube-player.ts b/apps/web/src/lib/use-youtube-player.ts index 3780fe836..4e9957935 100644 --- a/apps/web/src/lib/use-youtube-player.ts +++ b/apps/web/src/lib/use-youtube-player.ts @@ -85,7 +85,11 @@ export interface UseYouTubePlayerResult { ready: boolean; /** True when the IFrame API could not load/init (e.g. blocked or offline). */ failed: boolean; - seekTo: (seconds: number) => void; + /** + * Seek to `seconds`.
