BlogForge — End-to-End Blog Post Generator

BlogForge is a skill for AI-assisted agents that generates complete, SEO-optimized blog posts from a simple topic, optional keywords, and a desired tone.

Features

• Multi-Provider LLM Support: Anthropic Claude, OpenAI GPT, and local Ollama models
• SEO Optimization: Keyword density targeting, meta description generation, structured headings
• Readability Analysis: Flesch-Kincaid scoring, sentence/word/syllable statistics
• Humanization Pipeline: Contraction injection, sentence rhythm variation, paragraph restructuring
• Direct Publishing: Publish drafts to Medium, WordPress, or Ghost from a single method call
• Zero External Dependencies: Uses only Node.js built-in https, http, and crypto modules

model	string	❌	'anthropic/claude-sonnet-4-20250514'	Model identifier with provider prefix
humanize	boolean	❌	true	Apply humanization post-processing

Returns: { content, title, meta, readability, wordCount }

Example:

const forge = new BlogForge();

const post = await forge.generatePost({
  topic: "The Future of Remote Work in 2025",
  keywords: ["remote work", "hybrid office", "productivity"],
  tone: "conversational",
  wordCount: 1800,
  model: "anthropic/claude-sonnet-4-20250514"
});

console.log(post.title);
// "Why Remote Work Isn't Going Anywhere — And What's Coming Next"

console.log(post.readability);
// { fleschKincaid: 8.2, avgSentenceLength: 16.4, avgSyllablesPerWord: 1.4 }

console.log(post.meta);
// "Explore the future of remote work in 2025..."

Using OpenAI models:

const post = await forge.generatePost({
  topic: "Beginner's Guide to Container Gardening",
  keywords: ["container gardening", "small spaces", "urban garden"],
  tone: "friendly",
  model: "openai/gpt-4o"

Analyze the readability of any text.

Parameters:

Parameter	Type	Required	Description
text	string	✅	The text to analyze

Returns: { fleschKincaid, avgSentenceLength, avgSyllablesPerWord }

Example:

const forge = new BlogForge();

const stats = forge.analyzeReadability(
  "Short sentences work. They are punchy. Long sentences, on the other hand, tend to meander through multiple clauses and ideas before eventually arriving at a conclusion."
);

console.log(stats);
// { fleschKincaid: 7.1, avgSentenceLength: 12.3, avgSyllablesPerWord: 1.5 }

---

publishPost(options)

Publish a generated (or any) blog post to Medium, WordPress, or Ghost.

Parameters:

Parameter	Type	Required	Description
content	string	✅	Markdown blog post content

}

createAndPublish().catch(console.error);

Humanization Pipeline

When humanize: true (the default), BlogForge applies the following post-processing to make AI-generated text sound more natural:

1. Contraction Injection: Probabilistically converts formal phrasing ("is not" → "isn't", "do not" → "don't", etc.) ~60% of the time for natural variation
2. Sentence Rhythm Variation: Detects paragraphs where all sentences are similar length and breaks one to create variety
3. Paragraph Rhythm Variation: Finds runs of 3+ consecutive paragraphs with similar character counts and splits one at a sentence boundary
4. Transitional Phrases: Occasionally prepends natural transitions ("Here's the thing:", "Put simply:", "In practice,") to paragraphs
