What it does

Create Article is an agent skill from Abilityai/cornelius. Create long-form articles from knowledge base insights. Use when writing articles, blog posts, Substack content, or synthesizing knowledge into publishable content. Includes tone of voice, structure templates, and knowledge base integration.

Its SKILL.md is about 2.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files (for example `article-structure.md`, `metadata-template.md` and `tone-of-voice.md`).

It sits in Writing & Content, covering Blog and article writing, Brand voice and tone and Knowledge bases. It works with Substack and Google Drive. The repository describes itself as: AI-powered second brain template for Claude Code + Obsidian. The licence is MIT.

When your agent uses it

Writing articles
Substack content
Synthesizing knowledge into publishable content

Example prompts

“/create-article”

Requirements

Python 3
Pre-approved tools (allowed-tools): Read, Grep, Glob, Write, Bash, Task

Workflow steps

6 steps, taken from the step headings in SKILL.md.

Research Phase
Check Article Index
Create Article Structure
Write Article
Update Article Index
Upload to Google Drive

What it can do on your machine

Read from SKILL.md and the folder at commit fd5e9a4. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
- Read
- Grep
- Glob
- Write
- Bash
- Task
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- python3
- claude
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Create Article loads about 2.1k tokens when it runs. Until then it costs about 64 tokens; SKILL.md has 734 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~64
When it runs · the whole SKILL.md, loaded when a task matches: ~2.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
```
allowed-tools: Read, Grep, Glob, Write, Bash, Task
```

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Create Article Skill

Create publication-ready long-form articles by synthesizing insights from the user's knowledge base, following established tone of voice and structural patterns.

Quick Start

Search knowledge base for relevant permanent notes on the topic
Check Article Index to avoid duplicates and see related work
Create article folder with proper structure
Write article following tone of voice guidelines
Update Article Index with new entry
Upload to Google Drive Articles/cornelius_drafts for review

Google Drive	`Articles/cornelius_drafts` (shared drive)		✓	Upload article folder for review
Drive Folder Map	`.claude/resources/google_drive_folders.md`	✓		Google Drive folder IDs

Core Workflow

Step 1: Research Phase

Search the knowledge base for relevant insights:

bash

# Semantic search for topic
resources/local-brain-search/run_search.sh "your topic" --limit 15 --json

# Find connections to existing notes
resources/local-brain-search/run_connections.sh "Related Note Name" --json

Key locations to search:

Brain/02-Permanent/ - Core insights and permanent notes
Brain/AI Extracted Notes/ - AI-extracted insights
Brain/Document Insights/ - Research extracts
Brain/03-MOCs/ - Maps of Content for topic overviews

Enrich with BDG context (optional - reveals which notes are generative frameworks vs reflective):

bash

resources/brain-graph/run_brain_graph.sh inspect "Key Source Note" --json

Step 2: Check Article Index

MANDATORY: Read the Article Index before creating any article:

Brain/04-Output/Articles/ARTICLE-INDEX.md

Check for existing articles on similar topics
Identify gaps in topic coverage
Note related articles for cross-referencing

Step 3: Create Article Structure

Create folder and files:

Brain/04-Output/Articles/[article-name]/
├── [article-name].md          # Main article
├── _metadata.md               # Creation record
└── [images if needed]

Naming: Use kebab-case (e.g., cognitive-aware-ai-systems)

Step 4: Write Article

Follow the tone of voice and structure guidelines in:

tone-of-voice.md - Voice DNA and writing style
article-structure.md - Templates and patterns

Step 5: Update Article Index

Add entry to ARTICLE-INDEX.md:

Article name and link
Created date
Topic category
Status (Draft)
Notes

Step 6: Upload to Google Drive

Upload the article folder to Articles/cornelius_drafts on the shared Google Drive:

bash

# Upload the entire article folder (with images, metadata, etc.)
python3 .claude/scripts/google/google_drive.py upload-folder "Brain/04-Output/Articles/[article-name]" 1fxxbEwS86gguYXA1hJsFesr13ruXx80S --recursive

Google Drive folder IDs: See .claude/resources/google_drive_folders.md

Articles/cornelius_drafts folder ID: 1fxxbEwS86gguYXA1hJsFesr13ruXx80S
This puts the article where the user and a content agent can access it for review and publishing
The folder preserves the same structure as the local article folder

Key Principles

Voice Summary

the user's long-form voice transforms complex research into actionable business insights through methodical, evidence-based teaching. He challenges assumptions with data while maintaining accessibility, creating structured learning experiences that bridge academic rigor with practical application.

Show full SKILL.md (302 more words)Show less

Essential Do's

Open with clear learning objectives or discoveries
Cite specific research, studies, and data points
Use numbered lists and bullet points for complex info
Include TL;DR or summary sections
Define technical terms immediately after introducing them
Build arguments systematically from evidence to conclusion
Provide actionable frameworks readers can apply

Essential Don'ts

Never make claims without supporting evidence
Avoid emotional appeals without data backing
Don't use jargon without clear explanations
Never hedge with "maybe" or passive voice
Avoid corporate buzzwords ("synergy", "leverage", "utilize")

Platform-Specific Guidelines

Adjust content based on target platform:

Platform	Word Count	Depth	Structure
Substack	1,500-3,000	Deep dive, full research	Long-form template with TL;DR
Medium	1,500-2,500	Comprehensive but focused	Clear sections, strong hook
LinkedIn	800-1,200	Punchy, business-focused	Shorter paragraphs, bold insights
Blog	1,200-2,500	Flexible	Depends on audience

Platform Adjustments

Substack/Newsletter:

More personal voice allowed
Can use "I've found..." openings
Encourage replies/engagement at end
Include "Further reading" section

Medium:

Strong SEO-friendly title
Compelling subtitle
Use images/diagrams
End with clear takeaway

LinkedIn:

Shorter paragraphs (2-3 sentences)
More white space
Lead with insight, not setup
Business application focus
End with question to drive engagement

Content-Agent Integration

This skill can be called headlessly by content agent for content production:

bash

cd $PROJECT_ROOT
claude -p "/create-article <topic> for <platform>" --output-format json

Response format for a content agent:

json

{
  "result": "[Full article text with [[note citations]]]",
  "metadata": {
    "word_count": 1847,
    "platform": "substack",
    "cited_notes": ["Note 1", "Note 2", "Note 3"]
  }
}

When called by a content agent:

Return article text directly (don't save to file)
Include cited notes list
Focus on the user's unique/contrarian perspectives

Output Location

All articles go to: Brain/04-Output/Articles/[article-name]/

After creation, open the folder:

bash

open "Brain/04-Output/Articles/[article-name]/"
