---name: ruler-progress-renderdescription: Clone or update https://github.com/sxhzju/ruler-progress-animator and render a ruler progress video with default parameters. Use when users ask for requests like "绘制个尺子进度条", "做个尺子进度动画", "渲染 ruler progress", or ask to export the default demo video from this project.---

Ruler Progress Render

Workflow

1. Use scripts/render_ruler_progress.sh from this skill.
2. Pass workspace_dir as the first argument when the user specifies a folder; otherwise use current directory.
3. Pass output_path as the second argument when the user specifies output; otherwise use out/scaffold-demo-defaults-transparent.mov.
4. Run the script and wait for completion.
5. Return the final absolute output path printed by the script.

Command

bash scripts/render_ruler_progress.sh [workspace_dir] [output_path]

Behavior

• Reuse local repo if workspace_dir/ruler-progress-animator exists; otherwise clone from GitHub.
• Track remote default branch (origin/HEAD) when updating existing repo.
• Install npm dependencies.
• If bunx is available, run the new scaffold flow:
  • npm run remotion:ensure-browser
  • REMOTION_OUTPUT=... REMOTION_PROPS_FILE=shared/project/render-presets/default.json npm run remotion:render
• This flow reuses shared Chrome Headless Shell cache and avoids repeated browser downloads.
• If bunx is unavailable, fallback to npx remotion render with equivalent defaults as a compatibility path (without shared browser cache optimization).

Requirements

• git
• node
• npm
• network access for clone/update and dependency install
