Lemo Opuscar

---
name: lemo-opuscar
description: Direct and produce a short film made entirely in code, in one of the styles of the Lemo-Opuscar library (e.g. Impasto Oil Painting 油画厚涂, Watercolor Brush 水彩笔刷, Ukiyo-e 浮世绘, Satellite Briefing 卫星简报, Exploded Teardown 产品拆解, Microscope Story 显微叙事). Use when the user asks for a video, film, short, promo, explainer or animation (视频、短片、动画、宣传片) in a named style, including data, science and product explainers built from real material such as satellite imagery, laser scans, CAD files or archive scans (数据解说、科普、产品拆解); when they want a film made about their own topic and haven't chosen a style (help them choose); when they want to change a style and keep it as their own (改风格、做自己的风格); or when they ask which film styles there are. Not for editing or converting existing video files.

# Lemo-Opuscar

The styles, guides and tools ship with this plugin, in `library/` next to this file. Nothing is downloaded to tell you what to do.

1. **Get the library ready.** Run `sh "<skill base directory>/scripts/setup.sh"`. It copies the bundled library to its working folder (default `~/.lemo-opuscar`, so installed packages survive plugin updates) and prints `LIB=<path>` on its last line.
2. **Install the core tools early.** Start `sh "<skill base directory>/scripts/setup.sh" deps` right away, in the background if you can: it takes a few minutes the first time. Add `deps voice` or `deps music` later, only if the film needs them (`$LIB/TECHNIQUE.md` §1). Report missing system tools (Node, ffmpeg, Python) in your one round of questions; don't install system software yourself. Packages a style needs (its `STYLE.md` lists them) you install yourself, into the project folder.
3. **Follow the library.** Read `$LIB/AGENTS.md` and do what it says: finding the style, the one round of questions, the treatment, production and delivery.

What changes in skill mode:

| | |
|---|---|
| Project folder | `<name>/` in the folder the user started from (lowercase letters, digits, hyphens; avoid `#` and `?` in the path). Wherever the guides say `films/<name>/`, read this folder |
| Running tools | from `$LIB`, with the project's absolute path: `cd "$LIB" && node core/render/still.mjs "<project>" 1.5 3`. `sh tools/setup.sh` and `sh tools/fetch.sh` also run from `$LIB` |
| Library files in pages | absolute URLs: `/core/lib.js`, `/node_modules/three/…` (the project is served at `/@film/`) |
| Library files in scripts and `build.sh` | `$LIB/…`, with `LIB=<path>` at the top of `build.sh`; never `../..` |
| Demo films | not in this edition: no `demo/` source and no `poster.jpg`. Each style's `DEMO.md` (how its demo was made) is there; read it only after your `TREATMENT.md` is written, as the guides say. The films are on the gallery, https://lemomo-ai.github.io/lemo-opuscar/, if the user wants to watch one |
| Chinese narration | Kokoro's Chinese voices (offline) by default. edge-tts (`core/tts/tts_zh.py`) sounds better but sends the narration text to Microsoft's speech service: offer it in your one round of questions and use it only if the user agrees |
| Big downloads | only what the film needs, from the sources `$LIB/TECHNIQUE.md` §1 lists (npm, PyPI, Playwright's browser, this library's GitHub Releases, Hugging Face for the speech check). Name them in your one round of questions the first time |

Deliver what `$LIB/DIRECTOR.md` §11 lists, in the project folder, and tell the user where it is.
