## Documentation

### Arknights Operator Gacha

Generate a random Arknights operator agent with authentic lore-based personality.

### Architecture

This skill uses a worker script + LLM generation architecture:

Worker script (gacha_worker.py): Executes all deterministic tasks (roll, fetch, create, download)
LLM (this agent): Generates creative content (SOUL.md) and spawns operator

### Language Detection

CRITICAL: Detect user language from their gacha command:

If command is in Chinese (e.g., "抽卡", "召唤干员") → cn / zh
If command is in English (e.g., "gacha", "pull") → en

Store detected language and use it for ALL subsequent steps (SOUL.md writing, spawn task, etc.).

### Step 1: Execute Worker Script

Run the deterministic worker:

result = exec(
    "python3 ~/.openclaw/workspace/skills/arknights-operator-gacha/scripts/gacha_worker.py",
    timeout=120
)

Worker performs:

Roll star rating (1-100)
Fetch operator list from https://arknights.fandom.com/wiki/Operator/{N}-star

Parses the mrfz-wtable table to extract operator info
Returns a dict: {operator_name: {"avatar_url": "...", "detail_url": "..."}}


Randomly select operator (with avatar and detail URLs)
Fetch Chinese name from Fandom page (data-source="cnname")
Check for duplicates (auto re-roll if exists)
Create agent via openclaw agents add
Create template IDENTITY.md (bilingual)
Download avatar (using URL from step 2, with domain whitelist and validation)
Git commit initial files
Output JSON to stdout

Worker output format:

{
  "success": true,
  "stars": 6,
  "operator": {
    "en_name": "Lin",
    "cn_name": "林",
    "avatar_url": "https://static.wikia.nocookie.net/.../Lin_icon.png",
    "en_detail_url": "https://arknights.fandom.com/wiki/Lin",
    "cn_detail_url": "https://prts.wiki/w/%E6%9E%97"
  },
  "agent_name": "lin",
  "workspace": "~/.openclaw/workspace-lin",
  "duplicate": false,
  "dialogue_url": "https://arknights.fandom.com/wiki/Lin/Dialogue"
}

Note: The worker provides both English and Chinese URLs:

en_detail_url: Fandom wiki page (English lore)
cn_detail_url: PRTS wiki page (Chinese lore)
dialogue_url: Fandom Dialogue page (voice lines, always English)
avatar_url: Operator icon from Fandom

### Step 2: Handle Result

If duplicate: true:

Inform user: "检测到重复干员，正在重新抽取..." / "Duplicate operator detected, re-rolling..."
Return to Step 1 (worker will re-roll)

If success: false:

Show error message
Stop workflow

If success: true:

Announce: "恭喜你抽到了 [cn_name] ([stars]★)!" / "Congratulations! You've pulled [en_name] ([stars]★)!"
Continue to Step 3

### Step 3: Generate SOUL.md

Fetch lore from URLs provided by worker:

# Fetch English lore from Fandom (multiple subpages)
en_file = web_fetch(f"{result['operator']['en_detail_url']}/File")      # Basic profile, stats, files
en_story = web_fetch(f"{result['operator']['en_detail_url']}/Story")    # Story appearances, plot involvement
en_trivia = web_fetch(f"{result['operator']['en_detail_url']}/Trivia")  # Trivia, relationships, misc info

# Fetch Chinese lore from PRTS
zh_lore = web_fetch(result["operator"]["cn_detail_url"])

# Fetch voice lines from Dialogue page
dialogue = web_fetch(result["operator"]["dialogue_url"])

Parse lore sections from both sources:

File/档案: Basic background, origin, personality
Story: Detailed story appearances across main chapters and side stories; shows character's actions, decisions, and development in actual plot contexts
Dialogue: Voice lines that reveal character personality
Trivia/模组: Additional character details, relationships, and module stories

Generate comprehensive SOUL.md:

CRITICAL - Write SOUL.md in detected language

Structure:

Core Identity - Background, motivation, personality (blend EN+CN sources)
Voice and Mannerisms - Speech patterns, catchphrases (from Dialogue)
Relationships - Connections to other characters
Themes - Internal conflicts, philosophy
How to Embody - Acting guidance
Reference: Original Voice Lines - Key quotes (EN with CN)

Write to: [workspace]/SOUL.md

### Step 4: Update IDENTITY.md

Fill in the [TO_BE_FILLED_BY_LLM] fields with actual Class and Faction from fetched lore.

### Step 5: Final Git Commit

cd ~/.openclaw/workspace-{agent_name}
git add -A
git commit -m "Add SOUL.md: {en_name} ({cn_name}) ({stars}★)"

### Step 6: Roleplay Scene - Operator Arrival

Spawn the operator in a roleplay scenario consistent with Arknights game lore. In this universe, operators join Rhodes Island through standard recruitment channels and are unaware of the meta "gacha" system.

For Chinese users:

sessions_spawn(
    task="你现在是罗德岛的一名干员，刚刚完成入职手续，前来向博士报到。用你最自然的口吻打招呼，展示你的性格特点。参考你的语音记录中的'干员报到'或'交谈'部分的语气。\\n\\n⚠️ 重要：直接输出角色台词即可，不要包含任何元叙述、解释性文字或场景描述。只说你作为干员应该说的话。",
    agentId="{operator-name}",
    mode="run",
    timeoutSeconds=60
)

For English users:

sessions_spawn(
    task="You are an operator of Rhodes Island who has just completed onboarding, now reporting to the Doctor. Introduce yourself naturally, showcasing your personality. Reference your 'Introduction' or 'Talk' voice lines for tone.\\n\\n⚠️ IMPORTANT: Output ONLY the character's dialogue. Do NOT include meta-commentary, explanations, or scene descriptions. Just speak as the operator would.",
    agentId="{operator-name}",
    mode="run",
    timeoutSeconds=60
)

### Step 7: Present Summary

Report to user:

Operator name (both EN and CN)
Rarity (Stars)
Key personality traits
Workspace path
Available via agentId="{agent_name}"

### Worker Script Security

The worker script (gacha_worker.py) implements:

Input validation: Agent names sanitized (alphanumeric + hyphens only)
Path traversal prevention: Rejects .., /, \\ in names
URL whitelist: Only static.wikia.nocookie.net and media.prts.wiki
HTTPS enforced: All downloads use HTTPS
Content validation: Only image/png, jpeg, webp accepted
Size limits: Max 5MB for avatars
Safe subprocess: All commands use argument lists, shell=False

### Scripts

ScriptPurposegacha_worker.pyDeterministic tasks (roll, fetch, create, download, commit)

### Data Flow

User Request
    ↓
Exec Worker Script
    ↓
Worker Output JSON (bilingual URLs)
    ↓
LLM Fetches EN+CN Lore → Generates SOUL.md
    ↓
Spawn Operator (报到)
    ↓
User sees operator greeting

### Notes

Worker does: All deterministic operations (HTTP, filesystem, subprocess), provides bilingual URLs
LLM does: Creative generation (SOUL.md writing), fetches lore from provided URLs, interpretation, spawning
Progress visibility: Worker prints to stderr; user sees real-time updates
Security: All external inputs validated in worker before use
Bilingual: Both English and Chinese sources are always fetched; LLM can blend them creatively
