vss-ask-video skillA
vss-ask-video is agent-read markdown (skill) from nvidia-ai-blueprints/video-search-and-summarization: Use this skill when answering a question about previously analyzed or freshly scoped VSS video, or when reading a stored VSS memory job or record by id, or whenever a question should be answered by running the `vss memory introspect` command. Route through hot context, agent Markdown notes, `vss memory get` or `vss memory query`, `vss memory introspect`, or an exact-window `vss vlm run`. Not for video retrieval or metadata-answerable questions..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Ask a VSS video question Answer from the cheapest grounded source that can satisfy the question. For a running VSS deployment, use the installed `vss` CLI. Do not call an OpenAI-compatible `/chat/completions` endpoint directly or fall back to raw REST when a CLI command fails. This skill does not call `POST /generate` on the VSS agent. It requires a **deployed VSS with `vss configure` already run**. > **Hard rule — use the `vss` CLI.** `vss configure` has already pointed it at > the deployment's proxy, so every VSS action goes through that CLI and nothing > reaches the deployment any other way. > > Four things follow, because each has been done instead: > - use the `vss` on PATH (see Prerequisites) and call it as `vss`. Do not > build a parallel virtualenv or wrap it in another launcher; > - `vss vlm run` is the only eye on the video - never post to > `/v1/chat/completions`, `/generate` or `/v1/summarize` yourself, and never > decode or sample frames and answer from them; > - a named sensor is `--sensor`, never a file, and its window goes in > `--start-time`/`--end-time`, not the prompt. A name the deployment knows as a …
