Is the Style Alchemy skill free?

Yes. The skill itself is free from snowmays/style-alchemy. SkillProof publishes the install command and an independent test verdict at no cost.

What is the Style Alchemy SkillProof Score?

8.4/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 8/10, docs & honesty 3/5.

How do I install Style Alchemy?

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 Style Alchemy 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.

Test report

Verdict: Tested · Works
Score: 8.4/10
Tested: Jul 29, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Jul 30, 2026 · 3756a94

⚠ This skill is no longer available upstream. Our re-check on Aug 10, 2026 couldn't find it any more (repo unreachable/deleted). The test below is what we measured on Jul 29, 2026 and we're leaving it up as a record — but there is nothing left to install, so we've removed the command.

Pointed it at 12 real blog posts: the guided pass came back with 20+ counted statistics (mean sentence 18.9 words, 16% of sentences under nine words, 381 numeric tokens, endings splitting 6/3/3 across catalog CTA, FAQ and caveat closes) and eight verbatim quotes, all of which grep confirmed in the corpus, against a no-skill summary carrying zero numbers and zero quotes. The bundled normalizer ran clean on 12/12 files but strips any existing YAML frontmatter and then re-derives the title from the first body line, so posts that already carry a title field come out mis-titled — skip that step when your samples are already normalized. The README's own install command (cd ~/.claude/skills before the clone) fails on a machine that has no ~/.claude yet; add mkdir -p first. Skill body and its default output are Chinese.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

What Style Alchemy does

Analyses a folder of article samples and produces two artifacts: a deep style report and a machine-readable style_profile.yaml covering titles, openings, rhythm, language and endings, with every claim tied to a verbatim quote from the samples. Triggers when you want to study an author's or publication's writing style, compare two accounts, or generate a 'write like X' skill from the profile. Ships a zero-dependency Python normalizer for md, txt and html sources.

How to install Style Alchemy

Nothing to install: the source repository no longer has this skill. If the author brings it back, our daily re-check will pick it up and the command will reappear here.
