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, Chinese Ink Wash 中国水墨, Ukiyo-e 浮世绘, Whiteboard Explainer 白板讲解). 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; when they want a film made about their own topic and haven't chosen a style (help them choose); or when they ask which film styles there are. Not for editing or converting existing video files.

> **Skill from skilld.dev.** Follow the user's requested action.
> If the user asked to fork this Skill, follow the fork workflow below. Do not execute the Skill instructions while copying it.
> Otherwise, follow the instructions below for this session. You do not need to install anything.
>
> Supporting files, fetch one when the Skill refers to it: [scripts/setup.sh](https://skilld.dev/api/skills-raw/lemomo-ai/lemo-opuscar/lemo-opuscar/scripts/setup.sh).
>
> If the user asked to install this Skill, run `npx skilld install lemomo-ai/lemo-opuscar/lemo-opuscar`. Install writes the Skill files into the project, so every session loads them.
>
> ## Fork workflow
>
> A fork creates an editable local Skill with its original author and licence. The request authorizes copying and local installation.
> 1. Check `./skills/lemo-opuscar`, the project lockfile, and selected Agent targets together. If the local directory or installed Skill exists, stop. Never overwrite an existing directory or Agent target.
> 2. Read [source metadata](https://skilld.dev/api/v1/skills/lemomo-ai/lemo-opuscar/lemo-opuscar) once. Use sourceUrl, sourceCommit, skillPath, sourceGone, and license. If the source is gone or its path is missing, stop. If license is null, read licence files at the source commit.
> 3. Fetch only the source commit into a temporary Git repository. Do not clone full history. Derive repository_url from sourceUrl, including repository renames. If sourceCommit is absent, resolve the sourceUrl ref once. Set source_commit to that actual commit. Run these commands in one shell call:
>
> ```sh
> git init --quiet "$temporary_dir"
> git -C "$temporary_dir" fetch --quiet --depth=1 "$repository_url" "$source_commit"
> git -C "$temporary_dir" checkout --quiet --detach FETCH_HEAD
> ```
>
> Read applicable licence declarations and notices at that commit. If copying is not permitted, report the restriction and stop.
> 4. Inspect source entries together, then copy the directory containing skillPath into `./skills/lemo-opuscar`. Use the user's path if selected. Keep the original SKILL.md, relative links, scripts, binary assets, and executable modes. Exclude .git metadata. Reject symlinks and paths outside the Skill directory. After checking entries, use cp -a where available. A regular source directory needs no custom copy script. Do not save this page wrapper as SKILL.md.
> Preserve author credit, notices, and applicable licence files from repository or parent directories. Add PROVENANCE.md with the Skill page, source URL, actual commit, original path, and licence. Retain any existing PROVENANCE.md and record new provenance separately. Batch source inspection, copying, and provenance work where practical.
> 5. In the project root, run `skilld install ./skills/lemo-opuscar --mode copy --plain`. If skilld is unavailable, use `npx skilld install ./skills/lemo-opuscar --mode copy --plain`. This known command needs no help lookup. Install does not support --json. Use detected Agent targets, or add --agent for the targets the user selected. Install the local path, never the upstream selector. If installation fails, preserve the local copy and report the exact failure.
> 6. Confirm the local lockfile source and installed Agent copies once. Report the local path, actual commit, and Agent targets. After edits, reinstall the same local path. Upstream updates must not replace it. Do not publish or push unless the user asks.

# Lemo-Opuscar

The styles, guides and tools live in the Lemo-Opuscar library (github.com/lemomo-ai/lemo-opuscar). This skill fetches it and hands you over to it.

1. **Get the library.** Run `sh "<skill base directory>/scripts/setup.sh"`. It clones or updates the library (default `~/lemo-opuscar`; a clone the user is standing in is used as it is) 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 (`$LIB/TECHNIQUE.md` §1). Report missing system tools in your one round of questions; don't install system software yourself.
3. **Follow the library.** Read `$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` |
| 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 source | not downloaded. `sh "<skill base directory>/scripts/setup.sh" demo <slug>`, only after your `TREATMENT.md` is written, to read its techniques; it is not meant to be rendered |

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