Rumor Buster - 双引擎谣言验证

Dual-engine fact-checking skill for verifying news, claims, and messages through Chinese + English cross-verification and source tracing. Use when user wants to verify information authenticity, check if a message is true/false, validate news sources, or trace the origin of a claim. Supports /verify and /验证 commands with auto-detection of installed search engines.

Rumor Buster - 双引擎谣言终结者

Dual-engine fact-checking with Chinese + English cross-verification and source tracing.

When to Use This Skill

Use Rumor Buster when the user wants to:

• Verify if a message/news/claim is true or false
• Check the credibility of information
• Trace the origin of a rumor
• Validate sources of news
• Cross-check claims across languages

Trigger phrases:

• /verify "claim" or /验证 "消息"
• "Is this true?" / "这是真的吗？"
• "Check this" / "验证一下"
• "Rumor buster" / "谣言终结者"

Quick Start

First-Time Setup

When user first uses /verify, check for config:

python

CONFIG_FILE = "~/.rumor-buster-config"

if not os.path.exists(CONFIG_FILE):
    # Spawn setup sub-skill
    return sessions_spawn(
        task="Initialize Rumor Buster: detect search engines, configure Tavily API (optional), generate config file",
        agent_id="rumor-buster-setup",
        runtime="subagent",
        mode="session"
    )

Setup sub-skill handles:

1. Detect native search tools (kimi_search, web_search, web_fetch)
2. Detect multi-search-engine availability
3. Configure Tavily API (optional)
4. Generate ~/.rumor-buster-config

Basic Usage

python

def handle_verification(user_input):
    """Main entry point for verification requests"""
    # 1. Detect language
    lang = detect_language(user_input)
    
    # 2. Load config
    config = load_config(CONFIG_FILE)
    
    # 3. Extract query
    query = extract_query(user_input)
    
    # 4. Update session state (CRITICAL!)
    update_verification_state(query, lang)
    
    # 5. Perform verification
    results = perform_verification(query, config, lang)
    
    # 6. Generate summary
    return generate_summary(results, lang)

Verification Workflow

Phase 1: Chinese Search

Search Chinese sources for:

• First appearance of claim
• Spread path in Chinese media
• Official responses

python

def search_chinese(query, config):
    results = []
    
    # kimi_search (if available)
    if config["native"].get("kimi_search", {}).get("available"):
        results.append(kimi_search(query, limit=10, include_content=True))
    
    # multi-search-engine Chinese engines
    if config["multi_search_engine"].get("available"):
        for engine in config["multi_search_engine"].get("chinese", []):
            results.append(search_with_engine(engine, query))
    
    return aggregate_results(results)

Phase 2: English Search

Search English sources for:

• International perspective
• Fact-checking reports
• Official statements

python

def search_english(query, config):
    results = []
    
    # Tavily (if configured)
    if config["tavily"].get("available"):
        results.append(tavily_search(
            query,
            api_key=config["tavily"]["api_key"],
            max_results=10
        ))
    
    # multi-search-engine English engines
    for engine in config["multi_search_engine"].get("english", []):
        results.append(search_with_engine(engine, query))
    
    return aggregate_results(results)

Phase 3: Cross-Verification

Compare Chinese and English findings:

python

def cross_verify(cn_results, en_results):
    comparison = {
        "facts_match": compare_facts(cn_results, en_results),
        "timeline_consistent": compare_timeline(cn_results, en_results),
        "authorities_agree": compare_authorities(cn_results, en_results),
        "consistency_score": calculate_consistency(cn_results, en_results)
    }
    return comparison

Phase 4: Source Tracing

Trace claim back to origin:

text

Original Source → Early Spread → Mainstream Media → Social Media → User

Phase 5: Credibility Scoring

Calculate 0-100% score based on:

• Source reliability (25%)
• Cross-confirmation (25%)
• Evidence quality (20%)
• Authority acknowledgment (20%)
• Consistency (10%)

Session State Management (CRITICAL)

Must maintain current verification topic:

python

verification_state = {
    "current_query": None,
    "current_language": None,
    "chinese_results": None,
    "english_results": None,
    "analysis": None
}

def update_verification_state(query, lang):
    """Update state when new verification starts"""
    verification_state["current_query"] = query
    verification_state["current_language"] = lang
    verification_state["timestamp"] = datetime.now()
    # Reset other fields
    verification_state["chinese_results"] = None
    verification_state["english_results"] = None
    verification_state["analysis"] = None

Why this matters:

text

User: /verify "Claim A"
System: [Summary for A]
User: /verify "Claim B"  
System: [Summary for B]
User: detailed report  ← MUST return B, not A!

Load references/architecture.md for complete state management details.

Language Support

Auto-Detection

python

def detect_language(text):
    import re
    chinese_chars = len(re.findall(r'[\u4e00-\u9fff]', text))
    total_chars = len(text.strip())
    if total_chars > 0 and chinese_chars / total_chars > 0.3:
        return "zh"
    return "en"

Bilingual Output

All output respects detected language:

• Summary report language
• Detailed report language
• Interactive prompts

---

Reconfiguration

User can trigger reconfiguration:

• setup / 设置
• reset / 重新设置
• /rumor-buster setup

Handler:

python

def handle_reconfig(user_input):
    lang = detect_language(user_input)
    return sessions_spawn(
        task=f"Reconfigure Rumor Buster (language: {lang})",
        agent_id="rumor-buster-setup",
        runtime="subagent",
        mode="session"
    )

Best Practices

1. Always update session state when starting new verification
2. Cross-verify - never rely on single source
3. Check dates - old news often resurfaces
4. Trace to origin - don't stop at aggregators
5. Handle errors gracefully - continue if one engine fails
6. Respect rate limits - especially Tavily (1000/month free)
