Scenario's agent skills pack is trending: images, video, audio and 3D from Claude Code, with a price check first

What's in it, per the README. There are dozens of Scenario skills: storyboards, product shots, brand kits, video editing and color grading, Seedance music videos and storyboards, video ads, UGC-style clips, captions, audio, video assembly and motion loops. Separate skills handle the practical parts: a consistency and identity library to keep a character's face the same across shots, a quality gate, a refine loop, and model comparison. Scenario says the skills pick a model for each job and quote the cost before anything is generated.

The 3D OS part. Scenario's Nov 2 post (more than 1,100 likes) presented '3D OS' as 80 skills in six departments. These expert skills drive software on your own machine (Blender, Maya, ZBrush, Unreal, Unity, Godot, Roblox Studio) and don't use the Scenario MCP. Each folder's README says how it was built and how far it was checked.

Cost. The repo is free, but most generation goes through a Scenario account and uses credits. Install is one npx skills add command. You can pull just the scenario skill or the full set.

Our take: the per-shot price quote and the identity library are what make this worth a look for agencies, since budget and keeping the same face are the two things that usually go wrong in agent-made spots. Scenario followed up with an open motion-loop template pack on Nov 4 and a viral-format skill today, so expect frequent updates.
