What is it for?
Use it to write or improve TikTok, Instagram, or YouTube Shorts captions, on-screen text, hashtags, calls to action, and pinned comments.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

viral-captions-and-ctas scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 182 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Stop guessing what to post. Steal from the videos that blew up.

Viral captions and CTAs

Help the user write the text around the video: captions, on-screen text, hashtags, CTAs, and the pinned comment. This is the copy layer that decides whether a good video gets distributed, saved, and sent. It does not predict virality. It rules out patterns that suppress reach and pushes toward ones that tend to lift it.

For hooks and opening lines, see viral-hooks. For platform algorithm depth, see viral-tiktok-content, viral-youtube-shorts, viral-instagram-reels. For ideation, see viral-short-form-ideas. For full scripting, see the viral-short-form umbrella.

Operating principles (read these first, apply throughout)

  1. The caption is the SEO now. Instagram indexes captions for in-app search and for Google. TikTok reads captions as a main categorisation input. YouTube Shorts treats the title and first 125 chars of description as direct ranking signals. Hashtags aren't the discovery lever anymore. Words are.
  2. Most viewers watch on mute. Roughly 85% of social video is consumed silent. If the on-screen text doesn't carry the story, the video doesn't exist for most of the feed. Burn captions in. Don't trust auto-captions.
  3. Sends and saves beat likes and follows. The CTAs worth writing are tied to the algorithmically heavy actions (send, save, watch-to-end), not the lightweight ones ("like", "follow", "comment below") that pattern-match as engagement bait.
  4. Engagement bait is a distribution tax. "Comment YES for the link", "tag a friend", "like for part 2", "follow for more" all read as bait under Meta's and TikTok's policies. Each buys a small action and pays a reach penalty.
  5. One ask per video. Stacking like + save + share + follow + DM dilutes all five. Pick the action that matches the content type and earn it.
  6. Native, not cross-posted. A caption written for TikTok loses to one rewritten for Reels and another rewritten for Shorts. Different cutoffs, different keyword vocabulary, different hashtag conventions.
  7. Pattern-matching, not prediction. Captions and CTAs tend to perform a certain way. Nothing here guarantees a result. Honesty is the brand.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
