Generate platform-specific social post variants (Twitter/X, LinkedIn, Reddit) from one source input. Works with or without Node.js script. Includes platform reasoning, quality review, and guardrails against cross-posting spam.

Social Card Generator Transform one source message into platform ready social copy for Twitter/X, LinkedIn, and Reddit. This skill works two ways: With Node.js: Use generate.js for deterministic, automated output Without Node.js: Manual generation path built directly into this skill (no dependencies required) Mode Detect from context or ask: "One platform, all platforms, or all platforms with variants?" Mode What you get Best for quick 1 platform (user picks), optimized variant Testing a single channel standard All 3 platforms: Twitter, LinkedIn, Reddit Standard cross platform post deep All platforms + 3 variants each + A/B test guidance Campaign testing, maximizing reach Default: standard — use quick if they specify a platform. Use deep if they're running a content campaign and want options. ⚠️ MANDATORY: 4 Question Intake Before Generating Ask these before writing a single word of copy: 1. Source message: What's the core idea, update, or story? (Paste raw text or describe it.) 2. Tone goal: Informative? Provocative? Humble brag? Conversational? Educational? 3. Audience: Who needs to see this? (Founders, marketers, developers, general public?) 4. CTA: What do you want readers to do? (Visit link, reply, follow, share, start a conversation?) Without these answers, you'll get generic output that won't land on any platform. Platform Reasoning Rules (Built In — No External Script Needed) 🐦 Twitter/X Character limit: 280 characters (single tweet) or threaded for long form Tone: Punchy, direct, opinionated. Twitter rewards brevity and conviction. Hook structure: Lead with the most surprising or specific claim. No warm up. Hashtags: Max 1 2 directly relevant tags. Never stuff. CTA style: Short and embedded. "What's your take?" or "Link in reply." What kills Twitter posts: Long intros, passive voice, corporate speak, hashtag walls. Example hook pattern: "[Counterintuitive claim]. Here's why: [1 2 sentence reason]. [Engaging question]." 💼 LinkedIn Character limit: 3,000 characters for posts. First 2 lines before "See more" are critical. Tone: Professional but personal. Thought leadership with a human angle. Hook structure: First line must create curiosity or state a bold truth — not "excited to share." Hashtags: 3 5 max, at the end. Never in the body copy. CTA style: Invite discussion. "What's your experience with this?" works well. Opener rule: NEVER start with self promotional language. Lead with a lesson, story, or observation. What kills LinkedIn posts: Cringe openers ("I'm humbled to announce..."), excessive hashtags, no line breaks. Format tip: Short paragraphs (1 2 lines). White space is your friend. 🔵 Reddit Character limit: No hard limit, but long posts need clear structure with headers. Tone: Authentic, curious, community first. Reddit readers have a finely tuned BS detector. Hook structure: Situational — frame as a question, lesson learned, or genuine experience. Hashtags: Never. Not a thing on Reddit. CTA style: End with an open question that invites the community to share their take. Self promotion rule: Never lead with your own promotion. Frame everything as a contribution to the community. What kills Reddit posts: Obvious marketing, lack of genuine insight, "check out my [thing]" openers. Manual Generation Path (No Node.js Required) Follow this process exactly: Step 1: Distill the Core Message From the source input, extract: The ONE key insight or fact The "so what" — why does this matter to the audience? The evidence or story behind it Step 2: Generate 3 Platform Variants Twitter/X variant: Check: Under 280 chars for single tweet? If not, decide: cut or thread. LinkedIn variant: Check: Does the first line work before "See more"? Does it NOT start with "I'm excited to..."? Reddit variant: Check: Would this feel at home in the target subreddit? No hashtags? With Node.js (Automated Path) If generate.js is unavailable, use the Manual Generation Path above — same quality, just manual. Quality Self Review Pass (REQUIRED After Generating) After generating all 3 variants, run this review before delivering: Check Twitter LinkedIn Reddit Hook strong? (Would you stop scrolling?) ✅/❌ ✅/❌ ✅/❌ CTA present and clear? ✅/❌ ✅/❌ ✅/❌ Platform fit? (Tone matches platform norms) ✅/❌ ✅/❌ ✅/❌ Guardrails pass? (See below) ✅/❌ ✅/❌ ✅/❌ Flag the weakest variant and explain why: "The Reddit variant is the weakest because it still reads like a LinkedIn post — too polished, not community first." Guardrails (Never Violate) ❌ No identical copy cross posted — every platform variant must be meaningfully different in tone and structure ❌ No hashtag spam on LinkedIn — max 5, always at the end, never in the body ❌ No self promotional openers on Reddit — community value first, always ❌ No vague hooks — "I have some thoughts on X" is not a hook ❌ No copy that assumes platform context — Reddit readers don't know your LinkedIn audience Iteration Loop After delivering the 3 variants: 1. Ask: "Which variant feels most off? What's not landing?" 2. If hook is weak → rewrite the first line using a different angle (counterintuitive, numerical, story led) 3. If CTA is weak → try a question instead of a directive 4. If platform fit is off → re read the platform rules and rewrite from scratch for that platform Output Format Deliver: Skill by Brian Wagner AI Marketing Architect brianrwagner.com
