Buddy Reroll

Brute-force a new

/buddy

companion by finding a userID that hashes to the desired species and rarity.

通过暴力搜索 userID 来获取指定物种和稀有度的

/buddy

伙伴。

ブルートフォースで userID を探索し、指定した種族とレアリティの

/buddy

コンパニオンを取得します。

How It Works / 原理 / 仕組み

Claude Code generates companions deterministically:

hash(userID + SALT)

→

mulberry32

PRNG → rarity, species, eyes, hat, shiny. Same userID = same companion, always.

Claude Code 通过确定性算法生成伙伴：

hash(userID + SALT)

→

mulberry32

PRNG → 稀有度、物种、眼睛、帽子、闪光。相同 userID 始终生成相同伙伴。

Claude Code はコンパニオンを決定論的に生成します：

hash(userID + SALT)

→

mulberry32

PRNG → レアリティ、種族、目、帽子、シャイニー。同じ userID は常に同じコンパニオンになります。

To reroll: replace

userID

~/.claude.json

, clear

companion

field, restart.

重新抽取：替换

~/.claude.json

中的

userID

，清除

companion

字段，重启即可。

リロール方法：

~/.claude.json

の

userID

を置換し、

companion

フィールドをクリアして再起動。

Critical: Claude Code is Bun-bundled, so

Bun.hash()

(xxHash64) is the correct hash function. Node.js FNV-1a produces wrong results — the script MUST run under Bun.

Script Directory

Important: All scripts are located in the

scripts/

subdirectory of this skill.

Agent Execution Instructions:

Determine this SKILL.md file's directory path as
```
SKILL_DIR
```
Script path =
```
${SKILL_DIR}/scripts/<script-name>.mjs
```
Replace all
```
${SKILL_DIR}
```
in this document with the actual path

`scripts/reroll.mjs`	Brute-force target species+rarity, optionally apply to config

Prerequisites / 前提条件 / 前提条件

Claude Code >= 2.1.89 — the
```
/buddy
```
system was introduced in this version. The script auto-checks and exits if the version is too old.
Bun — required for correct hashing. Use
```
npx -y bun
```
if not installed globally.
API users only — This skill does NOT work for Pro/Max Plan subscribers whose
```
userID
```
is locked to their account. It only works for API users whose
```
userID
```
in
```
~/.claude.json
```
can be freely replaced.
Claude Code >= 2.1.89 —
```
/buddy
```
系统从此版本引入。脚本会自动检测版本，过低则退出。
Bun — 正确哈希所需。未全局安装时可用
```
npx -y bun
```
。
仅限 API 用户 — 本技能不适用于 Pro/Max 订阅用户（其
```

システムはこのバージョンで導入。スクリプトが自動でバージョンチェックします。
Bun — 正しいハッシュに必要。グローバル未インストールなら
```
npx -y bun
```
を使用。
API ユーザー限定 — Pro/Max プランのサブスクライバーは

Invocation / 调用方式 / 呼び出し方法

This skill can be invoked with or without arguments:

No args (
```
/webup-buddy-reroll
```
): Prompts the user to choose species and rarity interactively via
```
AskUserQuestion
```
before running.
With args (
```
/webup-buddy-reroll dragon legendary
```
): Skips the prompt and locks the choice to the given species and rarity directly.

本技能支持有参数和无参数两种调用方式：

无参数 (
```
/webup-buddy-reroll
```
)：运行前通过
```
AskUserQuestion
```
交互式提示用户选择物种和稀有度。
有参数 (
```
/webup-buddy-reroll dragon legendary
```
)：跳过提示，直接使用指定的物种和稀有度。

引数あり・なし両方で呼び出せます：

引数なし (
```
/webup-buddy-reroll
```
)：実行前に
```
AskUserQuestion
```
で種族とレアリティを対話的に選択。
引数あり (
```
/webup-buddy-reroll dragon legendary
```
)：プロンプトをスキップし、指定した種族とレアリティで直接実行。

Workflow

If no args provided: Use
```
AskUserQuestion
```
to ask the user to pick a species AND a rarity in a single prompt (two questions):
- Species question: Present 4 popular options (dragon, cat, axolotl, capybara) as choices. Each option's
```
description
```
  should list the remaining species so the user knows what's available via "Other", e.g. the first option's description: "Or type any of: duck, goose, blob, octopus, owl, penguin, turtle, snail, ghost, cactus, robot, rabbit, mushroom, chonk".
- Rarity question: Present all 5 tiers (legendary as first/recommended, then epic, rare, uncommon, common).
- Do NOT skip this step. Always ask even if the user mentioned a species — confirm their choice.
If args provided: Parse
```
<species>
```
and
```
<rarity>
```
from the args. Skip the prompt and proceed directly.

Run the script with

--apply
