What it does

When installed, the agent rewrites a single piece of content (a launch, essay, or update) into separate versions tailored to X, LinkedIn, Threads, and Bluesky, instead of pasting the same text everywhere. It keeps the author's voice, follows each platform's length and style norms, and avoids filler like hashtags, invented calls to action, or generic motivational closers. It returns a primary version, adapted variants, a short note on the changes, and any remaining publishing steps.

Great for

  • Creators or founders announcing a launch, release, or essay on several social networks
  • Marketers who want platform-appropriate variants without writing each from scratch
  • Solo builders who post often and want consistent voice across channels

Skip it if

  • Fully automated posting: the skill writes copy and does not itself publish, so it is not useful if you expect hands-off scheduling
  • Content that must be legally or medically reviewed before publication, since the skill applies style rules, not fact or compliance checks

Try asking

  • “Crosspost this launch note for X, LinkedIn, and Bluesky”
  • “Adapt this essay summary into a Threads post and an X thread”
  • “Post this changelog everywhere, keeping each version native to its platform”

  3. 3

    Ask for the task

    No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.

Get better results

  • Give the agent your original post or article as the source so it can preserve your real wording and claims
  • Ask for a short list of which platforms you want, so variants are not generated for channels you will not use
  • Review each variant yourself before posting, since the skill does not verify facts or check the agent's voice match
