oracle

# oracle 🔮 — Answer Oracle Draw one random line as the user's "answer of the day." This is a **fortune cookie**: the answer is picked at random from a pre-written pool and is **independent of whatever the user asked**. The question (if any) is ritual only — never read it to craft the answer. ## Inputs The user may invoke it bare (`/oracle`), with a forced language (`/oracle zh`, `/oracle en`), or with a question (`/oracle should I quit?`, `/oracle 我该辞职吗`). ## Step 1 — Pick the bank (language) Walk this ladder, **stop at the first match**: 1. **Forced:** the argument is exactly `zh` or `en` → use that bank (don't treat it as a question). 2. **Question language:** there is a question argument → if it contains any Chinese (CJK) character, use `zh`; otherwise `en`. 3. **Conversation language:** bare `/oracle` → use the language this conversation has been happening in. 4. **System fallback:** still unsure (brand-new conversation, first thing typed) → run `case "$LANG" in zh*) echo zh ;; *) echo en ;; esac`. The language only chooses the **bank**. It never chooses the line. ## Step 2 — Draw one line (truly random — do NOT pick yourself) Run exactly one shell command. Set `LANG_CODE` to `zh` or `en` from Step 1: ```bash d="${CLAUDE_PLUGIN_ROOT}/skills/oracle" # installed as a plugin (normal case) [ -f "$d/answers-en.txt" ] || d="$HOME/.claude/skills/oracle" # manual personal-skill copy [ -f "$d/answers-en.txt" ] || d="$(pwd)/skills/oracle" # running from the repo [ -f "$d/answers-en.txt" ] || d="$(pwd)" shuf -n 1 "$d/answers-${LANG_CODE}.txt" 2>/dev/null \ || awk -v seed="$RANDOM" 'BEGIN{srand(seed)} NF{a[++n]=$0} END{print a[int(rand()*n)+1]}' "$d/answers-${LANG_CODE}.txt" ``` The answer files ship beside this skill; `${CLAUDE_PLUGIN_ROOT}` points at the installed plugin root, and the fallbacks cover a manual copy or running from the repo. `shuf` is preferred; the `awk` branch is the fallback when `shuf` is missing (common on macOS), seeded with `$RANDOM` rather than the clock so draws in the same second don't repeat, with the `NF` guard skipping blank lines. Use the command's output verbatim — never substitute your own choice. ## Step 3 — Present it Open with the crystal ball, then the drawn line as a blockquote. If the user gave a question, echo it first for ritual (but the answer is unrelated to it). English: ``` 🔮 You give the crystal ball a shake… > <the drawn line> ``` Chinese: ``` 🔮 你摇了摇水晶球… > <抽到的那句> ``` Keep it to the opener + the line. No explaining, no "this means…", no choosing a "better" line. The whole charm is that it's random.
