The 1-Person Social Media Operating System in Claude (with Postiz) ⚡
Run an entire social media team inside Claude: Content Repurposing Skill, Anthropic Marketing Plugin, Canva MCP, and Postiz open-source scheduling.
⚡ TL;DR
You can run a complete multi-platform social media distribution engine as a solo founder without leaving Claude. By layering two custom skills (Content Repurposing and Avoid AI Writing), the Anthropic Marketing Plugin, the Canva MCP connector for graphic generation, and the open-source Postiz scheduling platform, one anchor article turns into fully designed, humanized posts published across LinkedIn, X, Instagram, and TikTok on autopilot.
The 5-Part Claude Social Stack
Here are the exact 5 components required to assemble the autonomous publishing loop:
In Claude, navigate to Customize → Skills → Add new skill. Upload the SKILL.md from the Content Repurposing repository. This teaches Claude how platform mechanics differ between LinkedIn's professional tone, X's punchy brevity, and Instagram's visual storytelling.
Step 2: Install the Avoid AI Writing Skill
Go to Customize → Skills → Add new skill and upload the avoid-ai-writing rulebook. This strips robotic filler words, forces bursty sentence lengths, and ensures your copy sounds conversational.
Step 3: Enable the Marketing Plugin & Canva MCP
From the Claude Plugin Directory, toggle the official Marketing plugin. Next, head to Customize → Connectors, locate Canva, and authenticate your account. Claude can now dispatch layout commands to Canva's API directly from chat.
Postiz is the open-source social posting engine that replaces expensive SaaS scheduling tools. Deploy it locally or on a cloud VPS:

EXECUTION LOOP
The 4-Prompt Daily Publishing Loop
Once your stack is installed, this is the exact repeatable workflow you run in a single Claude conversation:
DAILY CLAUDE PUBLISHING PROMPTS
[STEP 1 - REPURPOSE]
Here is my latest article / product teardown: [PASTE TEXT].
Using the Content Repurposing Skill, extract:
1. A 7-slide LinkedIn carousel outline focusing on the core framework.
2. A punchy 5-tweet X thread with a strong pattern-interrupt hook.
3. An Instagram caption with 3 tactical bullet points.
[STEP 2 - HUMANIZE]
Run the avoid-ai-writing skill across all three drafts. Eliminate any corporate buzzwords, vary sentence cadence, and ensure the tone sounds like an authentic growth operator.
[STEP 3 - GENERATE ASSETS]
Using Canva MCP, generate a clean 7-slide carousel template for the LinkedIn post using clean dark-mode styling (#181824 background, #ffffff text, #3b82f6 accent).
[STEP 4 - SCHEDULE WITH POSTIZ]
Send the finalized LinkedIn carousel and post text to Postiz. Schedule it for Tuesday at 8:45 AM EST. Send the X thread to Postiz scheduled for Tuesday at 11:15 AM EST.
