humanizer-skill: Free, open-source AI writing humanizer and detector

by Aboudjem · Claude Skill · ★ 218

Last updated: · Indexed by AgentSkillsHub · Auto-synced every 8h

Security audit verdict: SAFE · quality 68/100

None of the 42 rules matched — no credential harvesting, no data exfiltration, no curl-pipe-shell installer. Scanned against 42 published rules built on the SlowMist agent-security taxonomy, refreshed every 8 hours.

The quality score combines nine heuristic checks of the repo and its README: completeness, clarity, specificity, examples, structure, agent readiness, step-by-step content, instruction quality and security notes. It rates how well the project explains itself to an agent, not the code.

🧪 Tested by Agent Skills Hub

One of 23 tools we ran end to end on the same task for our Humanizer & Anti-Slop Skills page (2026-10-07).

Our pick (To check a text, not rewrite it): The only detector that flags structure in earnest: 8 of its 38 flags were about stated lessons, tidy endings and the like.

Result: Reads human 3.3/5 · Changed wording, not structure · removed 1 AI-leaning structure feature · kept every fact · flagged 38 (8 about structure) · 2.3 min

How this security grade is produced

Grades come from a rule-based scan built on the SlowMist agent-security taxonomy: 42 published rules, covering credential harvesting, data exfiltration, curl | sh installers and more. It is a first-layer scan, not a manual audit — we say so rather than overstate it.

The scale of the problem is documented independently: Liu et al. (2026), in a study of 31,132 agent skills, report that 26.1% contain security vulnerabilities. Our own full-catalog census is published as a citable open dataset.
