What its author says it does
Copied from the file, not written here
Transforms one piece of content into each marketing channel's native format — length, structure, hooks, and conventions — across LinkedIn, X threads, newsletters, Instagram, YouTube, short video, and blogs. Use when reformatting content for a specific channel. Trigger with "channel format", "adapt for LinkedIn", or "/multiply".

Channel Formats
Overview
Channel Formats adapts a single source into the shape each platform expects, then hands the draft to the brand layer. Format is the container; brand voice is the content.
Every channel has its own limits and conventions: a LinkedIn post is not an X thread, and a YouTube description is not an Instagram caption.
This skill reads the spec for the requested channel from the plugin's bundled channels/<id>.md files, drafts to that spec, and enforces the length limit.
It is instruction-driven and writes ready-to-paste files, with no accounts, keys, or network access.
Prerequisites
- The source content to adapt (a file path or pasted text) and one or more target channels.
- The bundled channel specs, which ship inside this skill at
channels/. The skill uses Glob and Read to load the right spec and Write to save each derivative. - An active brand profile so the
brand-voiceskill can run on top; if none exists, the caller is pointed to/brand-setup.
Channels (canonical IDs)
The channel ID is also the output filename (for example linkedin.md).
linkedin— professional single post — channels/linkedin.mdx-thread— multi-post thread — channels/x-thread.mdnewsletter— email newsletter section — channels/newsletter.mdinstagram— caption plus hashtags — channels/instagram.mdyoutube— description with timestamped chapters — channels/youtube.mdshort-video— TikTok, Reels, or Shorts script — channels/short-video.mdblog— short post or excerpt — channels/blog.md
Instructions
- Identify the target channel by its canonical ID from the list above.
- Read that channel's spec in
channels/<id>.md— each spec defines Format, Length, Structure, Do, and Avoid. - Draft the derivative to the spec, mapping the source's core message onto that channel's hook and structure.
- Check the character or word count and enforce the channel's limit; trim or split as the spec requires.
- Run the
brand-voiceself-check so the draft obeys the brand's tone, glossary, and compliance rules. - For localized copy, re-fit after transcreation because text expands or contracts across languages.
- Write one file per derivative, named after the channel ID.
Output
One ready-to-paste file per channel, named by the channel ID (linkedin.md, x-thread.md, and so on). Each file holds the fully drafted asset, already inside the channel's limit and already run through the brand self-check. Threads and multi-part formats are numbered as the platform expects.
Error Handling
| Condition | Behavior |
|---|---|
| Unknown channel ID | List the supported IDs and ask which to use; do not guess a format |
| Source too thin for a channel | Draft what the source supports and flag the gap rather than inventing facts |
| Draft exceeds the channel limit | Trim or split per the spec; never ship over-limit copy |
| No brand profile available | Draft to format, then note that the brand self-check was skipped |
| Localized text overflows after transcreation | Re-fit to the channel limit before writing the file |
Examples
Example: adapt one source to several channels
/multiply launch-note.md --channels linkedin,x-thread,instagram
Reads each channel spec, drafts three derivatives, runs the brand self-check, and writes linkedin.md, x-thread.md, and instagram.md.
Example: single channel from pasted text
Turn this paragraph into an X thread
Loads channels/x-thread.md, splits the idea into hooked, numbered posts within the per-post limit.
Example: re-fit localized copy
Fit the German LinkedIn draft back under the limit
Applies the LinkedIn spec to the expanded German text and trims it back within range.
