humanize-ai

humanize-ai is a skill for Claude Code from ChianW/C31. It costs 78 tokens per session (791 once invoked), scanned A, original, MIT.

A command-line tool that finds common patterns in AI-written text and can replace some of them automatically. It checks for inflated wording, filler, chatbot-like phrases, and other signals.

In plain words
What is it for?
Use it to inspect a file or standard input, produce a JSON analysis, or clean the text into a separate output file.
Why use it?
It helps remove wording that makes text sound machine-written or unnecessarily vague.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

humanize-ai scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/analyze.py, scripts/humanize.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 127 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Humanize CLI

Command-line tools for detecting and auto-fixing AI writing patterns.

Scripts

analyze.py — Detect AI Patterns

Scans text and reports AI vocabulary, puffery, chatbot artifacts, and auto-replaceable phrases.

# Analyze a file
python scripts/analyze.py input.txt

# Analyze from stdin
echo "This serves as a testament to our commitment" | python scripts/analyze.py

# JSON output for programmatic use
python scripts/analyze.py input.txt --json

Output example:

==================================================
AI PATTERN ANALYSIS - 5 issues found
==================================================

AI VOCABULARY:
  • testament: 1x
  • crucial: 2x

AUTO-REPLACEABLE:
  • "serves as" → "is": 1x
  • "in order to" → "to": 1x

humanize.py — Auto-Replace Patterns

Performs automatic replacements for common AI-isms.

# Humanize and print to stdout
python scripts/humanize.py input.txt

# Write to output file
python scripts/humanize.py input.txt -o output.txt

# Include em dash replacement
python scripts/humanize.py input.txt --fix-dashes

# Quiet mode (no change log)
python scripts/humanize.py input.txt -q

What it fixes automatically:

  • Filler phrases: "in order to" → "to", "due to the fact that" → "because"
  • Copula avoidance: "serves as" → "is", "boasts" → "has"
  • Sentence starters: removes "Additionally,", "Furthermore,", "Moreover,"
  • Curly quotes → straight quotes
  • Chatbot artifacts: removes "I hope this helps", "Let me know if", etc.

Workflow

  1. Analyze first to see what needs fixing:

    python scripts/analyze.py document.txt
    
  2. Auto-fix safe replacements:

    python scripts/humanize.py document.txt -o document_clean.txt
    
  3. Manual review for AI vocabulary and puffery flagged by analyze (these require human judgment)

  4. Re-analyze to confirm improvements:

    python scripts/analyze.py document_clean.txt

What ships with it

5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
