Viral Instagram Reels

Help the user plan, write, and diagnose Instagram Reels specifically. The mechanics here are different from TikTok and Shorts: sends drive cold reach, originality is enforced, and Trial Reels let you test a Reel on non-followers before it touches your follower feed. This skill encodes the Reels-only rules that change what a good Reel looks like today. It does not predict virality. It stacks the odds and tells you what to optimize for on this surface.

For cross-platform hook craft, see viral-hooks. For ideation systems, see viral-short-form-ideas. For deep caption work, see viral-captions-and-ctas. Use this skill when the question is Reels-specific.

Operating principles (read these first, apply throughout)

1. Sends per reach is the metric that buys you new audience. A DM share tends to count roughly three to five times more than a like when Instagram decides whether to push a Reel to non-followers. Design the Reel and the CTA to earn a share, not a like.
2. Watch time is still the biggest single signal. The first three seconds is the public inflection point. Drop-off before three seconds reads as a failed hook and caps the seed test.
3. Test cold before you commit. If the Reel is meant to reach non-followers and you have over 1,000 followers, default to Trial Reels first. A flop never touches your follower feed metrics. A winner gets a confirmed cold signal before you publish to everyone.
4. Originality is enforced, not encouraged. Reels that look like reposts are cut from cold distribution. Strip third-party watermarks, shoot or substantially edit your own footage, and keep the rolling 30-day window majority-original.
5. Captions and on-screen text are the SEO surface. Hashtags are not. Mosseri said directly that hashtags do not improve reach. Three to five relevant ones is the working ceiling. Put the keywords in the caption and on screen instead.
6. Reels is a discovery surface, not a follower surface. Your existing followers see only a fraction of your Reels. Plan every Reel for someone who has never heard of you.
7. Honest framing. Pattern-matching, not prediction. Say "this tends to lift sends" and explain why. Never promise a Reel will go viral.

Workflow

Adapt to the ask. Don't interrogate the user. If they want a hook fast, skip to step 3 and infer the rest.

1. Clarify the brief (ask only for what's missing): the topic or product, the goal (cold reach vs. follower nurture vs. follows from this Reel), the account type (Creator vs. Business, since audio access differs), and account size (under 1K means no Trial Reels yet).
2. Decide test path. If the goal is cold reach and the account is eligible, route through Trial Reels first → references/trial-reels.md.
3. Write the hook for the three-second cliff. Concrete, specific, no "hey guys" intro. See viral-hooks for the hook archetypes themselves; this skill covers what's different on Reels (text overlay timing, on-screen hook for sound-off viewers, hook that previews a shareable payoff) → references/reels-hook.md.
4. Structure for sends, not likes. Build the Reel so the payoff is a thing one specific person needs to see. Reframe the CTA from "follow for more" to "send this to the friend who [specific situation]" → references/sends-playbook.md.
5. Originality and audio pass. Confirm no TikTok or CapCut watermark, the footage qualifies as original under Meta's guidelines, and the audio choice fits the account type → references/originality-and-audio.md.
6. Caption, on-screen text, hashtags. Write the caption as SEO + a send-prompt. Put the keyword phrase on screen. Three to five hashtags max → references/caption-and-search.md (and see also viral-captions-and-ctas).
7. After publish: read Insights honestly. Skip rate, share rate, followers from this post. A viral view count without follows means the Reel did not make the topic legible → references/insights.md.

Modes (route by what the user asked)

• "Write me a Reel about X" → steps 1–6, using assets/reels-script-template.md. Default to a 15 to 30 second target unless the user specifies otherwise.
• "Should I test this with Trial Reels?" → references/trial-reels.md. Quick decision tree based on goal, account size, and risk tolerance.
• "Why isn't this Reel getting reach?" → diagnose mode. Walk references/diagnose-flop.md: originality flag, three-second drop, send signal, audio strip, caption SEO. Be specific about which lever is most likely the cause given the Insights they share.
• "Fix my Reels hook" → critique against assets/reels-hook-checklist.md, then rewrite the weak beats. Focus on the on-screen text, the first frame, and the three-second payoff promise.
• "Help me write the caption" → caption mode using references/caption-and-search.md. Keyword in the first line, send-prompt CTA, three to five hashtags. For deeper caption craft, gesture to viral-captions-and-ctas.
• "How do I use the Edits app" → references/edits-app.md. When it helps (no watermark, deeper Insights), what it doesn't fix (Edits won't save a weak hook), mobile-only at present.

Example

User: "I made a 22-second skincare Reel showing my morning routine. 18K views, 12 follows, low sends. What went wrong?"

Good response: name the most likely cause first (the Reel got reach but didn't make the topic legible, so viewers watched and scrolled), then walk the diagnostic in order. Ask for the share rate and skip rate from Insights. Check the on-screen text in the first second (was the niche legible without sound?). Check the CTA (was it "follow for more" or a send-prompt like "send this to the friend who buys every serum"?). Suggest a re-cut: keep the footage, rewrite the first three seconds to name the specific problem the routine solves, and replace the end card with a send-prompt aimed at one named persona. Offer to draft the new opening and the new caption. Never promise the re-cut will hit a number.
