vss-benchmark-vlm-qa SKILL.md skillB

vss-benchmark-vlm-qa from nvidia-ai-blueprints/video-search-and-summarization is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add nvidia-ai-blueprints/video-search-and-summarization/vss-benchmark-vlm-qa@v3.3.0-rc0

Pins v3.3.0-rc0 in mdr.lock. Pin the fingerprint instead.

Benchmark video Q&A accuracy and latency of a deployed RT-VLM (Cosmos Reason 3) via vss vlm run, using questions and videos from the DSS vss-devx-base dataset. Replaces the deprecated nat eval / vss-agent QA path. Not for tool-calling or trajectory evaluation, and not for LVS summarization throughput.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Benchmark video Q&A via `vss vlm`

Measure **accuracy** (LLM-as-judge vs ground truth) and **latency** of end-to-end
video question answering by calling **`vss vlm run`** against a deployed Cosmos
Reason 3 RT-VLM. Questions and clips come from DSS dataset **`vss-devx-base`**
(`nvdataset`).

This replaces `docker exec vss-agent nat eval` for the QA slice. It does **not**
score tool-calling or trajectories.

## When to use

- The user asks to benchmark / evaluate VLM video Q&A after vss-agent / NAT eval
  was removed.
- The user wants latency and answer accuracy on `vss-devx-base`.

## When not to use

- Tool-calling or trajectory evaluation — out of scope.
- LVS summarization throughput — use `vss-benchmark-video-summarization`.
- Ad-hoc single questions — use `/vss-ask-video`.

## Prerequisites

- A VSS stack with RT-VLM serving Cosmos Reason 3, and `vss configure` already run
  so `vss configure check` lists `rt_vlm` as `ok` and `vst` as `ok`.

  **Configure with a routable address, not `localhost`.** Clips are addressed as VIOS
  sensors so RT-VLM fetches them by URL; the URL VIOS mints is built from the

How to install

The exact contents, by fingerprint
mdr add nvidia-ai-blueprints/video-search-and-summarization/vss-benchmark-vlm-qa@sha256:59ce533fde89c6e6

The line at the top of this page pins the label v3.3.0-rc0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
