langchain-security-basics

Quick Review

High-quality security skill with comprehensive coverage of LangChain security best practices. The description clearly identifies use cases (API key safety, prompt injection, secure LLM interactions) that would trigger this skill. Task knowledge is excellent with concrete Python code examples covering secrets management, prompt injection prevention, safe tool execution, output validation, and audit logging. Structure is clear with logical step-by-step progression and a helpful security checklist. Novelty is moderate-to-good: while a CLI agent could handle individual security tasks, consolidating these patterns with validated code examples, specific regex patterns for sanitization, and production-ready implementations meaningfully reduces token overhead and error risk. Minor improvement area: the description could be slightly more specific about when NOT to use this skill (e.g., non-LangChain frameworks), but overall this is a well-executed, practical security skill.
