Social Card Generator Skill

Use this skill when a user needs one source message transformed into platform-ready social copy for Twitter, LinkedIn, and Reddit.

What it does

• Converts one source input into 3 platform variants.
• Enforces platform limits:
  • Twitter: 280 chars
  • LinkedIn: 3000 chars
  • Reddit: no hard limit in this tool
• Applies platform style:
  • Twitter: punchy + compact hashtags
  • LinkedIn: professional + business framing
  • Reddit: authentic + discussion-oriented
• Runs entirely offline for text/file workflows (no API required).

Files

• generate.js: CLI generator.
• templates.js: platform rules, tone guidance, hashtag strategy, and CTA formats.
• examples/: sample input and output.

Usage

npm install

# text input
node generate.js --text "We reduced onboarding time by 35% with a checklist." --stdout

# file input
node generate.js --file examples/input-example.md --outdir examples

# URL input (when network is available)
node generate.js --url https://example.com/post --platforms twitter,linkedin --stdout

Why this vs ChatGPT?

• Deterministic output shape: same rules every run.
• Zero prompt iteration for routine adaptation.
• Works without external AI APIs.
• Easy to automate in CI or content pipelines.

Before / After

Before (single source):

We shipped a new onboarding flow that cut setup time and improved week-1 activation.

After (platform-ready):

• Twitter: short hook, concise body, tight hashtags, direct CTA.
• LinkedIn: professional framing with practical outcome and discussion CTA.
• Reddit: conversational framing with an open-ended question.

Case study (real workflow)

A two-person SaaS team publishes one product update weekly. They previously rewrote each update manually for Twitter, LinkedIn, and Reddit (about 20-30 minutes total). With this skill they write one source update, run node generate.js --file update.md --outdir posts, and review 3 drafts in under 5 minutes before publishing.
