Real execution runs scripts/main.ts via `npx -y bun`; in this sandbox that was blocked as untrusted freshly-cloned external code, so it was judged on command and static code-trace correctness (a real user grants that trust once). Install was clean and verbatim, frontmatter parses as strict YAML, and the sips/cwebp/ImageMagick/Sharp fallback chain matches both the README and the actual code. In the A/B, the base arm's raw `cwebp -q 80` and the skill's own internal cwebp path resolve to the same command and would produce the same output on this test image (an 800x600 synthetic gradient PNG that grew 8,565 -> 67,850 bytes because a smooth PNG is already near-optimal for lossless) — the skill adds batch/temp-file/original-preservation safety but makes the identical quality-80 WebP decision and does not guard against a size increase, so it is same-quality, not better.
Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works
- Installs cleanly 5/5
- Triggers reliably 4/5
- Output vs. baseline 5/10
- Docs & honesty 4/5

Frequently asked questions
- Is the Baoyu Compress Image skill free?
- Yes. The skill itself is free from JimLiu/baoyu-skills. SkillProof publishes the install command and an independent test verdict at no cost.
- Does Baoyu Compress Image work with Claude Code?
- We tested it with Claude Code 2.x (agent harness) on Jul 11, 2026. Verdict: Works with setup.

- What is the Baoyu Compress Image SkillProof Score?
- 7.2/10 — installs cleanly 5/5, triggers reliably 4/5, output vs. baseline 5/10, docs & honesty 4/5.
- How do I install Baoyu Compress Image?
- Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.
- Can I use Baoyu Compress Image with Cursor, Copilot, Gemini CLI, Codex or other AI tools?
- The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.
