--- name: koubo-playbook description: "Topic judgment and writing playbook for Douyin talking-head voiceover, benchmarked against six measured accounts. Given a candidate topic, first run the five viral factors to decide whether it is worth doing, then pick one of six style tiers by topic type (benchmarked on / / / / / ), and finally generate the opening with the five title-hook patterns. Use when the user asks 'is this topic worth doing', 'what style should I write this voiceover in', 'give me a voiceover title / hook', 'which account should I benchmark', or 'reference the writing style of / / / / / '. Not responsible for finding trending topics (topic-radar) or turning a script into a finished video (koubo-video)." --- > Original skill · commissioned by the user · English edition, 2026-11-12 # koubo-playbook (topic judgment and writing playbook for talking-head voiceover) In one sentence: **a viral talking-head video = "a topic that touches ordinary people's own lives" × "a clear emotional stance" × "a 3-second hook built from contrast / a number / a question" × "one persona or scene memory point that can be reused long-term".** ## When to use - "Is this topic worth doing" - "What style should this voiceover be written in / which account should I benchmark" - "Give me a voiceover title / opening hook" - "Reference the writing style of / / / / / " ## When not to use - Finding trending topics, needing sourced evidence → `topic-radar` - A finished script that must become a vertical video → `koubo-video` - Long-form hot-take opinion writing / short commentary (not a voiceover script) → `hot-take-writing` ## Three hard rules 1. **Judge before writing**: every candidate topic goes through the "five viral factors" first; if it does not pass, propose a different angle or drop it — do not force the write. 2. **Pick the style before the script**: once the topic type is fixed, choose one of the six style tiers (with its benchmark account) first, then write in that style's sentence patterns; do not blend styles. 3. **Every conclusion must point back to a sample**: saying "this kind of topic can go viral" requires pointing at a specific viral piece from the benchmark account (with its like count) as evidence — no hand-waving. ## Topic judgment checklist (the five viral factors) For a candidate topic, score each item (yes = 1 / no = 0), **only ≥3 points is worth doing**: 1. **Relevance to ordinary life**: does it touch ordinary people's wallet, daily life or emotions directly? ( hit likes on a national five-year plan by hammering "what does this have to do with ordinary people"; pure macro topics such as the Russia-Ukraine war or the Fed generally land mid-tier) 2. **Emotional conflict**: does it take a clear stance and have emotion, dare to make a judgment? ("the deformed 'business KTV'", "scenic spots are ugly and all identical") 3. **Contrast / reversal**: is it counter-intuitive or does it reverse expectations? ("foreigners are scrambling for Chinese bags" — the reversal of the natural order, "who says China has no Samsung") 4. **Concrete numbers / events**: are there impactful numbers or a specific event instead of an abstract concept? (500 billion, 15.8 billion, 30 billion against 30 billion) 5. **Timeliness**: is it happening now rather than old news? ## Six style cards (topic → style → benchmark account) | Topic type | Style | Benchmark account | Title pattern | |---|---|---|---| | Social phenomena / consumer complaints / domestic brands | Phenomenal rant | | long title + strong emotion + question | | Livelihood / prices / tech news | Fast news commentary | | extremely short 5–10 character question | | Macro / capital markets | Vertical opinion | | short sentences + topic hashtags + "what does it even mean" | | Consumer / society / tech (needs internet feel) | Internet-native rant | | internet memes + colloquial speech | | Cognition / values / macro judgment | Aphoristic philosophy | | one-liner / antithesis / philosophical turn | | Macro made simple / livelihood explainer | Scenario-based explainer | | "honey, I heard that XXX" | Full viral samples are in `references/benchmarks.md`. ## Five title-hook patterns 1. **Question / suspense**: why / is it true that / what do we do / who actually won 2. **Contrast / reversal**: counter-intuitive comparison (the natural order reversed, who says there is none) 3. **Number hook**: open on an impactful number (500 billion, spending 388, 5 yuan per 1000 times) 4. **Emotion words**: deformed / natural order reversed / leaving in tears / not the least bit remorseful 5. **Scenario-based persona**: turn the persona into a fixed opening (husband-and-wife Q&A, aphoristic sage) ## Workflow 1. Read the candidate topic → score it against the "five viral factors", continue only at ≥3, otherwise change the angle or drop it. 2. Look up the "six style cards" by topic type → fix the style and the benchmark account. 3. Use the "five title-hook patterns" plus the benchmark account's sentence patterns to generate the title and the opening hook. 4. When delivering, point out which viral piece from the benchmark account supports the style and the topic (with its like count).
