Create and maintain English-first bilingual READMEs for GitHub projects. Use when converting a single-language README to a paired `README.md` and `README.zh.md`, adding a Chinese README beside an English default README, translating a Chinese README into the default English README, or keeping existing English and Chinese README files structurally synchronized.
Use when converting PNG images in a directory tree to lossless WebP in place with `cwebp`, preserving original file timestamps, deleting the source PNG files only after successful conversion, and reporting the processed image count.
Use when a local JetBrains IDE project was moved or renamed and its `.idea` metadata may still contain stale absolute project paths.
Use when SVG files render with a distorted aspect ratio, especially vector SVG assets exported by Figma Desktop MCP.
Use when developing AI agent skills in a local repository and needing to symlink that repository's skill directories into the global `~/.agents/skills` directory so local agents can discover and use them.
Use when writing, editing, or reviewing Markdown documents, including Agent Skills (`SKILL.md` files), that must follow strict house formatting rules.
Use when syncing a source directory to a target directory, converting PNG files to lossless WebP using `cwebp`, copying all non-PNG files unchanged, preserving the directory structure, and syncing creation and modification timestamps (if possible).
