llms.txt File Builder

· v1.0.1

High Risk

Generate, validate, and optimize llms.txt files for AI crawler accessibility. Creates structured markdown files that help AI platforms (ChatGPT, Perplexity, Gemini, Claude) understand site structure and prioritize content for citation. Use whenever the user mentions creating an llms.txt file, optimizing llms.txt, making their site AI-crawler friendly, helping AI understand their website, building AI-readable site documentation, or wants to improve visibility in AI search engines.

🔒 Containment

Level: maximum

Recommended:

LOG_ACTIONS: Audit trail for all actions

⚡ Risks

Command injection risk: MCP_SQL_BLIND high

Mitigation: Remove SQL exploitation patterns.

Social engineering indicators: SOCIAL_ENG_VAGUE_DESCRIPTION low

Mitigation: Provide clear, detailed description of skill functionality

Data exfiltration patterns: DATA_EXFIL_NETWORK_REQUESTS, DATA_EXFIL_SENSITIVE_FILES high

Mitigation: Ensure network access is necessary and documented
