Image Compressor
Compresses images using best available tool (sips → cwebp → ImageMagick → Sharp).
Script Directory
Scripts in scripts/ subdirectory. {baseDir} = this SKILL.md's directory path. Resolve ${BUN_X} runtime: if bun installed → bun; if npx available → npx -y bun; else suggest installing bun. Replace {baseDir} and ${BUN_X} with actual values.
| Script | Purpose |
|--------|---------|
| scripts/main.ts | Image compression CLI |
Preferences (EXTEND.md)
Check EXTEND.md in priority order — the first one found wins:
| Priority | Path | Scope |
|----------|------|-------|
| 1 | .baoyu-skills/baoyu-compress-image/EXTEND.md | Project |
| 2 | ${XDG_CONFIG_HOME:-$HOME/.config}/baoyu-skills/baoyu-compress-image/EXTEND.md | XDG |
| 3 | $HOME/.baoyu-skills/baoyu-compress-image/EXTEND.md | User home |
If none found, use defaults.
EXTEND.md supports: Default format, default quality, keep-original preference.
Usage
${BUN_X} {baseDir}/scripts/main.ts <input> [options]
Options
| Option | Short | Description | Default |
|--------|-------|-------------|---------|
| <input> | | File or directory | Required |
| --output | -o | Output path | Same path, new ext |
| --format | -f | webp, png, jpeg | webp |
| --quality | -q | Quality 0-100 | 80 |
| --keep | -k | Keep original | false |
| --recursive | -r | Process subdirs | false |
| --json | | JSON output | false |
Examples
# Single file → WebP (replaces original)
${BUN_X} {baseDir}/scripts/main.ts image.png
# Keep PNG format
${BUN_X} {baseDir}/scripts/main.ts image.png -f png --keep
# Directory recursive
${BUN_X} {baseDir}/scripts/main.ts ./images/ -r -q 75
# JSON output
${BUN_X} {baseDir}/scripts/main.ts image.png --json
Output:
image.png → image.webp (245KB → 89KB, 64% reduction)
Extension Support
Custom configurations via EXTEND.md. See Preferences section for paths and supported options.

Reference for the Claude API / Anthropic SDK — model ids, pricing, params, streaming, tool use, MCP, agents, caching, token counting, model migration. TRIGGER — read BEFORE opening the target file; don't skip because it "looks like a one-liner" — whenever: the prompt names Claude/Anthropic in any form (Claude, Anthropic, Fable, Opus, Sonnet, Haiku, `anthropic`, `@anthropic-ai`, `claude-*`, `us.anthropic.*`, `[1m]`); the user asks about an LLM (pricing/model choice/limits/caching) — never answer from memory; OR the task is LLM-shaped with provider unstated (agent/MCP/tool-definition/multi-agent/RAG/LLM-judge/computer-use; generate/summarize/extract/classify/rewrite/converse over NL; debugging refusals/cutoffs/streaming/tool-calls/tokens). SKIP only when another provider is being worked on (overrides all triggers): OpenAI/GPT/Gemini/Llama/Mistral/Cohere/Ollama named in the query; OR `grep -rE 'openai|langchain_openai|google.generativeai|genai|mistralai|cohere|ollama'` over the project hits (run this grep FIRST if no provider named — don't Read the file).
