Unverified: 1 category
A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

Provenance No attestation
The registry publishes no build provenance for this version, so there is nothing to verify.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
wecut_analyze Analyse a video ~144
Measure a video that worked: shots and pace, cuts in the first 3 s, flashes, beat and tempo, pauses, a silent platform outro, and (with a transcript) words per minute and the hook's words. Returns a sheet of frames, one per shot, as an image: look at it for the headline card, text style, framing and captions. Use the result to pick or write a recipe.
| Name | Type | Req | Description |
|---|---|---|---|
| file | string | yes | Video in the workspace. |
| frames | integer | – | Frames on the sheet (default 12). |
