Content Writer

A multi-platform content generation system with structured workflow, SEO optimization, and anti-AI auditing. Supports unlimited brand profiles across Claude Code, Claude AI, ChatGPT, and Gemini.

What it does

Content Writer orchestrates content creation through five sequential phases — discuss, plan, execute, verify, ship — so each piece goes through structured development instead of a single prompt.

Key Features

1. Multi-Profile Support — Create unlimited writer profiles for different brands, clients, or voices. Switch between them per project.
2. Brand Voice Capture — Builds a detailed profile before generating content so output reflects your tone, not generic AI defaults.
3. SEO Integration — Keyword targeting, meta tags, and title optimization happen during the verify phase, not as an afterthought.
4. Anti-AI Auditing — Flags and removes ~25 common markers that make AI-written content recognizable.
5. Multi-Platform — Works across Claude Code (terminal), Claude AI (web/app), ChatGPT (Custom GPT), and Gemini (Gem).

"Write me a LinkedIn post about remote work productivity"

The system will:

1. Check for profiles (create one if needed)
2. Guide you through the 5-phase workflow
3. Output content as artifacts/files

Multi-Profile System

Manage multiple brands, clients, or voices. Each profile includes:

• Brand identity, audience, voice/tone
• Content strategy and publishing preferences
• Products/services with descriptions
• CTAs for different platforms
• Case studies with metrics

Commands by Platform

Per-Project Profiles

Claude AI: Each Claude Project remembers its own profile. Project A can use "My-SaaS" while Project B uses "Personal-Blog".

Claude Code: Single active profile per workspace. Switch with /writer:profile-use.

ChatGPT/Gemini: Upload different profile files for each conversation.

Platform Comparison

Voice Profile System

When you create a profile:

1. URL Scanning (optional) — Provide a blog/website URL, and the system analyzes existing tone
2. 10-Topic Questionnaire — Brand identity, audience, voice/tone, content strategy, products, case studies, CTAs, publishing workflow, SEO strategy
3. Writing Samples (optional) — Paste examples for direct voice calibration

The profile is applied to every content generation call. You cannot generate content without a profile — this is intentional.

Development

Building Adapter Files

After modifying reference files, rebuild adapters:

npm run build:adapters

This copies canonical references to each adapter's folder.

Verification

Run tests to verify all commands work:

npm run verify

Releasing

The ship script handles versioning, building, and packaging:

# Patch release (2.3.0 -> 2.3.1)
npm run ship patch

# Minor release (2.3.0 -> 2.4.0)
npm run ship minor

# Major release (2.3.0 -> 3.0.0)
npm run ship major

# With npm publish
npm run ship minor -- --publish

This will:

1. Update package.json version
2. Update CHANGELOG.md
3. Build adapter files
4. Create distribution zips in dist/
5. Commit and tag
6. Optionally publish to npm

Who it's for

• Founders and operators producing content regularly without a dedicated writer
• Developers building content pipelines who want repeatable, auditable process
• Agencies and consultants managing content for multiple brands with different voices
• Multi-platform users who want consistent workflow across Claude, ChatGPT, and Gemini

If you write content once a week and don't have a process problem, this is overkill. If you're producing content at volume and want consistent quality without manually quality-checking every draft, this is for you.
