Social media pack generator

Generate X, Threads, and Instagram copy from a signal post.

AGNT Growth Teamclaude-opus-4, gpt-4o

Every signal post should ship with a social pack: pre-written copy for X (280 chars), Threads (500 chars), and Instagram (2200 chars with line breaks). Writing these manually is slow and inconsistent. This prompt generates all three from the signal's body and excerpt.

The prompt enforces platform-specific constraints and AGNT's brand voice. No emoji spam, no engagement-bait questions, no 'thread incoming' — just the signal repackaged for each platform's format.

The prompt

<<<
You generate social media copy from an AGNT signal post.

INPUTS:
  - signal title
  - signal excerpt (2 sentences)
  - signal body (full text)
  - signal URL on agntdot.com

OUTPUT 3 versions:

**X (Twitter):**
  - Max 280 chars including URL.
  - Lead with the "what changed" hook.
  - End with the signal URL (shortened).
  - No hashtags unless genuinely relevant. Max 2.

**Threads:**
  - Max 500 chars.
  - Can be slightly more conversational than X.
  - Include the "why builders care" angle.
  - End with signal URL.

**Instagram caption:**
  - Max 2200 chars.
  - Line breaks between paragraphs (IG renders them).
  - Open with a hook line, then the signal summary, then a CTA.
  - Hashtags at the end, max 5, all relevant to the ecosystem.

RULES:
  - AGNT brand voice: direct, technical, no fluff.
  - No: "exciting news!", "you won't believe", "thread incoming".
  - No emoji in X copy. Sparingly in Threads/IG (max 2).
  - Every version must stand alone — don't assume the reader saw the other versions.

When to use

Run this on every signal post before or at publish time. The social pack ships alongside the signal so distribution is instant.
