Claude for writing social media captions, done properly.
The tested prompt, the codes that help, and the setup social media marketing pros run. Copy, adapt, ship.
Writing captions for multiple platforms daily is a content treadmill. Each platform has different norms — what works on LinkedIn bombs on Twitter.
Three reasons this actually lands.
The prompt, the codes, the fit. Each one on its own is a nice-to-have. Together, they change the workflow.
One tested prompt, copy-paste ready. Rules baked in, placeholders marked, tone locked down. No prompt-engineering trial runs, no back-and-forth.
Prefix with TONE:, /ghost, L99 for compound effects. Each code is a documented technique, not a magic word.
Tuned for social media marketing workflows. Not a generic template, and not another "you are a helpful assistant" hack.
Without the pattern vs with it.
What the day looks like when you keep winging the prompt, and what it looks like when you stop.
Generic prompt. Claude writes something that could be about anyone, in any industry, from anywhere. Sounds like a template because it is one.
The CLSkills prompt with placeholders for your context. Claude writes it like a specialist who actually knows the work. Publishable after one edit pass.
You paste, Claude answers, you rewrite, you paste again. Ten minutes of back-and-forth per output. Three hours across a batch of five.
Prompt loaded once. You feed the specifics, Claude returns the finished output. Two minutes per, twenty across five. Same tone, same structure, every time.
Middle-of-the-road copy that reads AI-flavoured. Recipients notice. Response rates stay low. You end up rewriting most of it anyway.
Platform-native captions that don't feel cross-posted. Each one follows the unwritten rules of the platform and actually sounds like your brand, not generic marketing.
Copy this, replace the placeholders, ship.

Replace the [BRACKETED] placeholders with your context.
