uso-zatsugaku

name: uso-zatsugaku description: Generate three short Japanese fake-trivia items from a user theme or three prompt words. Use when the user asks for 嘘雑学, plausible-but-false trivia, "雑学をどうぞ", or a theme such as "スマホの雑学"; uses a local word pool instead of the what3words API unless official what3words behavior is explicitly requested.

3語嘘雑学

Purpose

Make harmless Japanese fake trivia that sounds briefly believable, then works as "まあ全部ウソなんだけどね".

Default output hides the reasoning process:

雑学をどうぞ

* ...
* ...
* ...

Inputs

If the user gives a theme, keep it as word 1 and draw 2 random words from the skill directory: node scripts/random-words.mjs --count 3 --theme "スマホ"
If the user gives 3 words, use them directly. Accept ///a。b。c, comma-separated, or whitespace-separated forms.
If neither is given, draw 3 words from the skill directory: node scripts/random-words.mjs --count 3

The helper prefers at least 2 concrete local-pool words (biology, food, everyday) and may mix 1 general word. If the set includes a personal name, political/military/crime/safety term, pure connector, or a word too abstract to picture, rerun the helper.

Workflow

Do the following internally. Do not show intermediate sections unless the user asks for the process.

Generate 10-15 candidates.
Build most candidates from exactly 2 of the 3 words. Cover all pairings: 1+2, 2+3, 1+3. Use all 3 only when stronger.
For about 5 promising candidates, add a plausibility bridge:
- 広く知られる事実: familiar object, habit, visible feature, custom, industry practice, or everyday observation.
- 織り交ぜる嘘: false origin, hidden reason, measuring trick, naming story, ritual, rule of thumb, or invented link.
Score the reinforced candidates:
- 説得力: reason-to-conclusion bridge is clear.
- 意外性: not merely true advice or a normal household tip.
- 身近さ: listener can picture the scene quickly.
- 嘘としての切れ味: possible for a second, funny when revealed false.
- 混ざり具合: at least 2 prompt words are meaningfully used.
Pick 3 items with distinct word pairings, settings, and explanation tricks.

Writing Rules

Write final trivia in Japanese.
Make each item one sentence when possible.
Use concrete details: color, shape, sound, placement, count, hand movement, heat, weight, smell, drying, storage, measurement, memory, or crowd flow.
Use time/place/industry anchors only when they help. Do not make every item historical or geographic.
Prefer false origins for familiar things, unrelated facts connected by a neat lie, or real-looking habits with invented reasons.
Avoid real people, real companies, politics, illness, disasters, crime, discrimination, sensitive attributes, and any false claim that could affect health, safety, legal, or financial decisions.

Selection Rules

Drop items that could simply be true practical advice unless the false part is clearly visible.
Drop items whose familiar object is vague or whose action is hard to picture.
Drop near-duplicates; do not choose 3 items with the same pair, setting, or trick.
Favor items that make the user think "本当？" before the reveal.

Debug Output

Only when the user asks to see the process, use:

///{word1}。{word2}。{word3}
