langchain-common-errors

Quick Review

Excellent skill providing comprehensive LangChain error diagnostics with clear examples and actionable solutions. The description accurately reflects capabilities and provides clear trigger phrases for CLI invocation. Task knowledge is strong with code snippets for each error type, root causes, and multiple solution approaches. Structure is clean and well-organized with logical categorization (Authentication, Import, Rate Limiting, etc.). Novelty is moderate-to-good: while error diagnosis could be searched online, having consolidated, version-aware solutions with working code examples in one skill saves significant tokens and reduces back-and-forth debugging cycles for a CLI agent. Minor improvement area: could include a quick diagnostic workflow or decision tree at the start to triage unknown errors.
