What changed

Adds an opt-in adapter for Google's agentic video understanding path via the Interactions API.

  • accepts YouTube URLs and file URIs
  • supports agentic and static processing per video, including mixed requests
  • defaults to gemini-3.7-flash
  • returns a durable execution receipt with model, sources, processing modes, text, and token count
  • validates inputs before a provider call

Why

Google AI Studio announced agentic video understanding on September 1, 2026. The capability actively inspects transcript, frames, and audio with adaptive frame sampling, which maps directly to EventRelay's video-to-event pipeline and the See → Act → Record → Review loop.

Sources:

Verification

  • python -m compileall src/integration/gemini_agentic_video.py tests/unit/test_gemini_agentic_video.py — passed
  • dependency-free fake-provider harness — passed request construction, async invocation, receipt, and validation
  • full pytest was not available in the local execution environment (No module named pytest); repository CI remains the merge gate

No production deployment or default-path switch is included.

Execution receipt — security workflow diagnosis

Verified failing run: Security Scan 33605167703, job trivy (100167379816).

The container build stops before Trivy executes because:

npm ci --workspace=apps/web --production --legacy-peer-deps
Invalid: lock file's @ai-sdk/gateway@4.0.23 does not satisfy @ai-sdk/gateway@4.0.72
Invalid: lock file's postcss@8.5.21 does not satisfy postcss@8.5.26
ERROR: process ... did not complete successfully: exit code: 1

The PR changes only:

  • src/integration/gemini_agentic_video.py
  • tests/unit/test_gemini_agentic_video.py

Interpretation: the failed security workflow is a repository package/lock synchronization blocker, not a vulnerability finding from this adapter. Trivy was skipped because the image never built.

Action: recorded here rather than mixing an unrelated lockfile rewrite into this focused PR. The next safe repair is to reconcile the web workspace lockfile in its canonical dependency-maintenance work, then rerun Security Scan.

Other exact-head checks currently verified successful: CI, Coverage, CodeQL, Secret Scan, and Dependency Review.

Execution receipt — Gemini 3.8 adoption boundary and benchmark scope

New verified fact (2026-09-02): Google released Gemini 3.8 Flash, and Vercel AI Gateway exposes it as google/gemini-3.8-flash with video input. Main now uses that gateway path in 25e6fbb.

Separate verified fact: Google's current agentic-video guide still documents processing: "agentic" only for Gemini 3.7 Flash, 3.6 Flash, and 3.5 Flash-Lite. It does not document Gemini 3.8 for this specialized Interactions API mode.

Sources:

Decision: TEST. Keep this draft's default at gemini-3.7-flash until Google explicitly confirms 3.8 support for processing: "agentic". Do not treat the generic gateway video path and the Interactions API agentic path as equivalent.

Re-scoped value of this PR: retain it as the explicit agentic-processing/receipt adapter and use it to benchmark against the main gateway extractor on the same videos:

  1. Video Pack schema completeness and grounded timestamps
  2. Token use and actual cost
  3. Latency
  4. Failure behavior
  5. Provenance/receipt quality

The adapter already permits a model override through GEMINI_AGENTIC_VIDEO_MODEL, so no speculative model-pin change is needed today.

TypeScript build fails with "Variable 'promise' is used before being assigned" because promise is referenced inside its own initializer closure under strict definite-assignment analysis

Addressed in commit 18c876a: the adapter now extracts text from the locked SDK's outputs response shape, tests use the installed Interaction model, and unsupported/non-YouTube video URIs are rejected before provider calls.

Addressed in commit 18c876a. URI parsing now rejects malformed or unsupported references before request construction, and regression coverage includes malformed URIs with a nonblank prompt.

Automated checkpoint update (pr-iteration-loop)

This PR was blocked on the build CI check by a typecheck regression in apps/web/src/lib/video-pack-store.ts that was unrelated to this PR's own changes (it originated on main and was already fixed there by #1658). I cherry-picked that fix (main@1c54062c5) onto this branch, plus a small ruff UP035 lint fix in the new src/integration/gemini_agentic_video.py module, and pushed both as append-only commits — no rebase, no force-push, no unrelated file changes.

Verification on the new head:

  • PYTHONPATH=src pytest tests/unit/test_gemini_agentic_video.py --no-cov -q → 5 passed
  • ruff check src/integration/gemini_agentic_video.py tests/unit/test_gemini_agentic_video.py → all checks passed
  • python -m compileall -q src/integration/gemini_agentic_video.py tests/unit/test_gemini_agentic_video.py → passed
  • npx tsc --noEmit -p . in apps/web → no video-pack-store.ts errors; the 9 remaining errors are pre-existing NODE_ENV test-file errors present identically on main (unrelated baseline noise, not introduced here)
  • next build could not be exercised end-to-end in this sandbox (no network egress to fetch Google Fonts at build time) — this is a sandbox/environment limitation, not a code regression, and is unrelated to this PR's diff

I also opened a canonical tracking issue, #aw_gemvid1, since the required "Canonical issue and evidence" check needs a Closes #<issue> reference and specific PR-body sections (## Canonical issue, ## Outcome, ## Risk, ## Production evidence) with real content. There is currently no safe-output tool available to me to edit an existing PR's description directly, so I'm posting the properly-formatted body content below for a maintainer (or a follow-up automation run) to copy into the PR description:


Closes #aw_gemvid1

Canonical issue

Closes #aw_gemvid1 — tracks the opt-in Gemini agentic video adapter.

Outcome

Adds an opt-in adapter for Google's agentic video understanding path via the Gemini Interactions API. Callers can request agentic or static processing per video (including mixed requests in one call), defaulting to gemini-3.7-flash, and receive a durable execution receipt (model, sources, processing modes, text, token count). Inputs are validated before any provider call so malformed YouTube URLs/file URIs fail closed without a network round trip.

Risk

  • Risk level: low — purely additive, opt-in module with no caller wired into the production paste-URL path yet.
  • Failure mode: adapter validates and rejects malformed requests before calling any provider.
  • Rollback: revert this PR; no other code path depends on this module.

Production evidence

No production deployment or default-path switch is included; this is an additive, opt-in module not yet wired into the live paste-URL flow.


No further action from this automation this run — please review and merge/close as appropriate.
