Yes. The skill itself is free from Hakku/finnish-humanizer. SkillProof publishes the install command and an independent test verdict at no cost.

What is the Finnish Humanizer SkillProof Score?

9.2/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 8/10, docs & honesty 5/5.

How do I install Finnish Humanizer?

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 Finnish Humanizer 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.

Verdict: Tested · Works
Score: 9.2/10
Tested: Aug 5, 2026
Environment: Claude Code 2.x (agent harness)

⚠ 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 Aug 5, 2026 and we're leaving it up as a record — but there is nothing left to install, so we've removed the command.

Fed it a 109-word slab of AI-written Finnish about remote work and scored the result with a marker counter built from the skill's own 27-pattern list: the source carried 20 pattern hits, a plain no-skill rewrite still left 7, and the skill-guided rewrite left 0. The baseline kept the clichés the skill names explicitly, including 'on tullut jäädäkseen', 'jatkuvaa kehittämistä' and four nominalisation chains, and used zero Finnish particles. Docs hold up under checking: the reference file really does contain 27 numbered patterns (12 Finnish-specific plus 15 universal) and every one of the 15 platform files listed in the README exists in the repo. One honest caveat, sentence-length variance barely moved, so the claimed rhythm fix is the weakest part of the effect.

What Finnish Humanizer does

Rewrites Finnish text to remove the markers of AI generation: filler openers, vague authority claims, significance inflation, nominalisation chains, missing particles and metronomic sentence rhythm. Triggers when you paste Finnish text and ask to humanise it, make it sound natural, or analyse which AI patterns it contains. Ships a 27-pattern reference file plus an analyse-only mode that lists findings without rewriting.

How to install Finnish Humanizer

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.
