**Humanizer relies exclusively on plain-text formats—Markdown, YAML, and JSON—supplemented by a single Python validation script, with no compiled binaries or language-specific dependencies required.**

The blader/humanizer repository is a deliberately lightweight, portable AI-agent skill designed for maximum compatibility. According to the source code, the project avoids compiled code entirely, utilizing universal text-based formats that AI agents can parse natively, along with one minimal Python utility for package integrity checks.

## Core File Formats and Languages

### Markdown for Skill Documentation

**Markdown (.md)** serves as the primary content format in Humanizer. The repository uses Markdown files to define the core skill behavior and project documentation:

- **[`SKILL.md`](https://github.com/blader/humanizer/blob/main/SKILL.md)** — Contains the main skill prompt with an optional YAML header that agents parse as structured plain text
- **[`README.md`](https://github.com/blader/humanizer/blob/main/README.md)** — Provides installation instructions and usage documentation

These files are stored as raw text, making them readable by any AI agent without preprocessing or compilation.

### YAML for Configuration

**YAML (.yaml` / `.yml`)** handles all configuration definitions across different agent platforms and CI workflows:

- **[`agents/openai.yaml`](https://github.com/blader/humanizer/blob/main/agents/openai.yaml)** — Defines OpenAI-compatible agent configurations
- **[`.github/workflows/validate.yml`](https://github.com/blader/humanizer/blob/main/.github/workflows/validate.yml)** — Configures GitHub Actions to run validation on every push

The YAML structure allows Humanizer to declare agent parameters and automation triggers without executable code.

### JSON for Plugin Metadata

**JSON (.json`)** stores structured metadata for Claude-compatible integrations:

- **[`.claude-plugin/plugin.json`](https://github.com/blader/humanizer/blob/main/.claude-plugin/plugin.json)** — Contains the plugin manifest including `name`, `description`, `entrypoint`, and `version` fields

This file enables the Claude ecosystem to recognize and load the Humanizer skill as a native plugin.

## Python Validation Utilities

While the skill itself requires no runtime language, the repository includes one **Python (.py)** script for development-time quality assurance:

- **[`scripts/validate-package.py`](https://github.com/blader/humanizer/blob/main/scripts/validate-package.py)** — Validates the consistency of the skill package, checking that [`SKILL.md`](https://github.com/blader/humanizer/blob/main/SKILL.md) metadata is valid, README content matches skill patterns, and plugin files remain consistent

You can execute this validation locally using:

```bash
python3 scripts/validate-package.py

```

Expected output:

```

✅ SKILL.md metadata is valid
✅ README matches skill patterns
✅ Plugin files are consistent

```

## CI/CD Configuration

The repository leverages **GitHub Actions Workflow (.yml)** files for continuous integration:

- **[`.github/workflows/validate.yml`](https://github.com/blader/humanizer/blob/main/.github/workflows/validate.yml)** — Automatically triggers the Python validation script on every push, ensuring package integrity before changes merge to main

## Summary

- **Humanizer uses four primary formats**: Markdown for content, YAML for configuration, JSON for metadata, and Python for validation
- **Zero compiled dependencies**: The skill operates entirely through plain-text files parsed by AI agents
- **Single Python utility**: Only [`scripts/validate-package.py`](https://github.com/blader/humanizer/blob/main/scripts/validate-package.py) contains executable code, and it serves a development-time validation role
- **Universal compatibility**: The text-based architecture ensures the skill works across OpenAI, Claude, and other agent platforms without language barriers

## Frequently Asked Questions

### Does Humanizer require compiling any code?

No. According to the source code analysis, Humanizer contains no compiled binaries or build steps. The skill functions entirely through plain-text files (Markdown, YAML, JSON) that AI agents read directly. The only Python script ([`validate-package.py`](https://github.com/blader/humanizer/blob/main/validate-package.py)) runs as interpreted code for development validation.

### What programming language powers the Humanizer skill logic?

The skill logic itself has no programming language dependency. The core behavior resides in [`SKILL.md`](https://github.com/blader/humanizer/blob/main/SKILL.md), a Markdown file with a YAML header that agents parse as instructions. Unlike traditional software libraries, Humanizer operates as a declarative prompt package rather than imperative code.

### How does Humanizer validate its package structure?

The repository uses [`scripts/validate-package.py`](https://github.com/blader/humanizer/blob/main/scripts/validate-package.py) to enforce consistency. This Python script checks that [`SKILL.md`](https://github.com/blader/humanizer/blob/main/SKILL.md) contains valid metadata, that the README aligns with skill patterns, and that plugin configuration files remain synchronized. GitHub Actions runs this script automatically via [`.github/workflows/validate.yml`](https://github.com/blader/humanizer/blob/main/.github/workflows/validate.yml) on every push.

### Can I use Humanizer without Python installed?

Yes. End-users consuming the skill through Claude, OpenAI, or other agents do not need Python. Python is only required for contributors who wish to run the local validation script before submitting changes to the repository.
