Humanizer is an AI writing skill that detects and rewrites common signs of AI-generated prose. It helps agents preserve meaning, match audience and tone, reduce hype and filler, and produce writing th

Skills are installed by placing their folder where your agent loads skills.

Installable writing skills for AI agents that need to sound like a careful writer, explain a procedure plainly, or check a draft for familiar AI prose signals. Choose the skill for the job in front of you; a mixed document does not need to pass through the whole suite.

Current source: 2.12.16

The humanizer catalog now protects the writer's judgments. A stated reaction, preference, or ranking counts as source meaning even when the reason is missing, a repair keeps the scope the source claimed, and an empty concession or contrast is reported instead of invented.

The detector keeps house-style typography out of authorship scoring. Curly punctuation, a prose em dash, and an Oxford comma together report at low severity as a style check in plain text, and they cannot move the score, label, or confidence. The "X is dead; long live Y" phrase is editorial judgment now, so essay titles and supported contrasts stay clean.

The latest GitHub release is 2.12.16; the current source tree matches it.

See CHANGELOG.md for the full history.

Need	Skill	Version
Preserve a writer's voice while removing stiff or generic prose	`humanizer`	`1.7.10`
Write procedures, errors, runbooks, and clear technical sections	`simple-english`	`2.4.2`
Scan for AI-writing signals or verify that an edit preserved structure	`ai-writing-detector`	`1.2.2`
Draft reader-facing prose with a deterministic Vale review gate	`writing-prose`	`1.2.4`
Pick the right register for an audience: three modes plus tone overlays	`writing-voice`	`1.1.0`

Use one skill for the job a section needs.

What You Can Do

Rewrite without replacing the writer. Humanizer keeps facts, technical terms, uncertainty, point of view, and deliberate style while cutting filler.
Control technical form when clarity is the priority. Simple English offers strict and STE-flavored modes plus a Python linter.
Measure signals without making authorship claims. AI Writing Detector reports issue bands and can compare a before/after pair for damaged code, URLs, or structure.
Pair editorial judgment with a repeatable gate. Writing Prose ships its Vale configuration, house rules, and long-form references with the skill.
Match the audience. Writing Voice picks Chat, Human, or Worker, then optional tone overlays. It routes to Humanizer's voice-profile table and does not invent a personality the source never had.

Minimal Examples

Humanizer is a writing workflow rather than a command-line filter. Install the skill, then ask the agent to rewrite, clean up, critique, detect, or minimally edit supplied text. Improve the writing without inventing facts or a new personality.

Simple English includes a deterministic linter:

python3 skills/simple-english/scripts/voice_lint.py path/to/draft.md

AI Writing Detector exposes a zero-dependency Node.js scan and a preservation check:

node skills/ai-writing-detector/scripts/analyze.js path/to/file.md
node skills/ai-writing-detector/scripts/validate-cli.js before.md after.md
bash skills/ai-writing-detector/scripts/smoke.sh

Writing Prose runs the bundled Vale rules through one wrapper:

bash skills/writing-prose/scripts/vale-lint.sh path/to/draft.md

Detector output is signals_only. It is not proof of authorship and should not be used as a score to chase.

Install

Each directory under skills/ is self-contained. Copy only the skill you need:
