Claude Marketplace Listing for blader/humanizer: Manifest Structure and Installation Guide

The blader/humanizer skill is published to the Claude Marketplace via a JSON manifest located at .claude-plugin/marketplace.json that defines the plugin metadata, owner attribution, and installation parameters required to rewrite AI-generated text into natural prose.

The blader/humanizer repository provides a Claude skill that transforms robotic, algorithmic-sounding content into human-like writing without altering the underlying meaning. Its marketplace presence is governed by a structured manifest file that enables seamless discovery and one-click installation within the Claude ecosystem.

Marketplace Manifest Structure

The primary marketplace definition resides in .claude-plugin/marketplace.json at the repository root. This file serves as the authoritative source for how Claude presents, categorizes, and installs the Humanizer skill.

Core Metadata Fields

The manifest contains top-level metadata that identifies the package and its author:

• name: humanizer — The unique identifier used in marketplace searches and installation commands
• owner: An object containing name: "blader" and url: "https://github.com/blader" — Links to the author's GitHub profile for attribution and credibility
• description: "Install Humanizer as a Claude plugin." — The concise tagline displayed on the marketplace browse page

Plugin Configuration Array

The plugins array contains the actual executable skill definition with the following properties:

• name: humanizer
• source: ./ — Points to the repository root as the installation source
• description: "Rewrite AI‑sounding text so it reads naturally without changing what it says." — The functional description of what the skill accomplishes
• license: MIT — Permits unrestricted use, modification, and distribution
• keywords: ["writing", "editing", "humanize", "prose", "style"] — Discovery tags for marketplace search functionality

Runtime Integration with plugin.json

While marketplace.json handles marketplace discovery and presentation, the companion file .claude-plugin/plugin.json supplies runtime execution metadata. This secondary manifest includes version tracking, detailed author information, and precise file system paths to the skill definition located in SKILL.md. Together, these JSON configurations constitute the complete technical specification for the marketplace listing.

Installing and Inspecting the Skill

Users can programmatically verify the marketplace entry before installation by fetching the raw manifest directly from the repository.

import json
import urllib.request

url = "https://raw.githubusercontent.com/blader/humanizer/main/.claude-plugin/marketplace.json"
with urllib.request.urlopen(url) as resp:
    data = json.load(resp)

print("Marketplace name:", data["name"])
print("Description:", data["description"])
print("Plugin description:", data["plugins"][0]["description"])

To add the skill to your Claude environment, reference the marketplace manifest URL in the "Add Plugin" interface using the repository path to .claude-plugin/marketplace.json.

Using the Humanizer Skill

After installation, invoke the skill using the @humanizer mention followed by your text transformation request:

@humanizer
Please rewrite the following paragraph to sound more natural:
> "The algorithmic process was executed with a high degree of efficiency..."

Claude will process the request through the Humanizer skill defined in SKILL.md, applying the transformation logic to produce text that maintains the original meaning while eliminating artificial or robotic phrasing patterns.
