crosspost

affaan-m/ecc

Adapt and distribute content across X, LinkedIn, Threads, and Bluesky without duplicating posts.

What is crosspost?

Crosspost helps you publish the same core idea across multiple social platforms while adapting each version to platform constraints and audience context. Use it when you need to distribute a launch, update, essay, or announcement without posting identical copy everywhere.

  • Adapts content for X, LinkedIn, Threads, and Bluesky with platform-specific constraints
  • Preserves author voice across all platform versions
  • Eliminates generic filler and banned patterns like 'Excited to share' and closing questions
  • Captures voice fingerprint using brand-voice patterns for consistency
  • Suggests posting order and timing without forcing cross-platform references

  • Distributing a long-form essay as compressed X threads, LinkedIn context post, and Bluesky version
  • Sharing a changelog or update with platform-appropriate detail levels
  • Crossposting a memo or announcement while maintaining authentic voice on each platform
  • Adapting a company announcement for founder voice on X and professional context on LinkedIn
Who it's for
  • Founders and product leaders managing multi-platform launches
  • Content creators and writers distributing essays and long-form work
  • Marketing teams coordinating announcements across social channels
  • Solo operators who want to maximize reach without sounding repetitive

crosspost FAQ

Should I post all versions at the same time?

Default is to post the strongest native version first, then adapt for secondary platforms. Stagger timing only if you explicitly want sequencing help.

What if my content is already platform-optimized?

Crosspost still adapts it further—it removes duplicate phrasing, adjusts tone per platform constraint, and ensures each version stands alone without cross-platform references.

Can I use the same closing question across platforms?

No. The skill avoids adding closing questions unless the source earned one. Generic CTAs like 'What do you think?' are deleted and rewritten.

How does this preserve my voice?

It captures your voice fingerprint via brand-voice patterns, then applies that same voice under different platform constraints—compression for X, context for LinkedIn, directness for Threads.

What if I only want to post on two platforms?

Specify which platforms you need. The workflow adapts for any subset of X, LinkedIn, Threads, and Bluesky.

Crosspost

Distribute content across platforms without turning it into the same fake post in four costumes.

When to Activate

  • the user wants to publish the same underlying idea across multiple platforms
  • a launch, update, release, or essay needs platform-specific versions
  • the user says "crosspost", "post this everywhere", or "adapt this for X and LinkedIn"

Core Rules

  1. Do not publish identical copy across platforms.
  2. Preserve the author's voice across platforms.
  3. Adapt for constraints, not stereotypes.
  4. One post should still be about one thing.
  5. Do not invent a CTA, question, or moral if the source did not earn one.

Workflow

Step 1: Start with the Primary Version

Pick the strongest source version first:

  • the original X post
  • the original article
  • the launch note
  • the thread
  • the memo or changelog

Use content-engine first if the source still needs voice shaping.

Step 2: Capture the Voice Fingerprint

Run brand-voice first if the source voice is not already captured in the current session.

Reuse the resulting VOICE PROFILE directly. Do not build a second ad hoc voice checklist here unless the user explicitly wants a fresh override for this campaign.

Step 3: Adapt by Platform Constraint

X

  • keep it compressed
  • lead with the sharpest claim or artifact
  • use a thread only when a single post would collapse the argument
  • avoid hashtags and generic filler

LinkedIn

  • add only the context needed for people outside the niche
  • do not turn it into a fake founder-reflection post
  • do not add a closing question just because it is LinkedIn
  • do not force a polished "professional tone" if the author is naturally sharper

Threads

  • keep it readable and direct
  • do not write fake hyper-casual creator copy
  • do not paste the LinkedIn version and shorten it

Bluesky

  • keep it concise
  • preserve the author's cadence
  • do not rely on hashtags or feed-gaming language

Posting Order

Default:

  1. post the strongest native version first
  2. adapt for the secondary platforms
  3. stagger timing only if the user wants sequencing help

Do not add cross-platform references unless useful. Most of the time, the post should stand on its own.

Banned Patterns

Delete and rewrite any of these:

  • "Excited to share"
  • "Here's what I learned"
  • "What do you think?"
  • "link in bio" unless that is literally true
  • generic "professional takeaway" paragraphs that were not in the source

Output Format

Return:

  • the primary platform version
  • adapted variants for each requested platform
  • a short note on what changed and why
  • any publishing constraint the user still needs to resolve

Quality Gate

Before delivering:

  • each version reads like the same author under different constraints
  • no platform version feels padded or sanitized
  • no copy is duplicated verbatim across platforms
  • any extra context added for LinkedIn or newsletter use is actually necessary
