error-message-manager

What problem does it solve?

Julia packages often throw vague, low-context error messages that leave users guessing what went wrong and how to fix it. This Skill transforms cryptic exceptions into structured diagnostics that clearly state the failure, show expected versus actual values, and provide actionable suggestions.

Core Features & Use Cases

• Structured Error Rewrites: Converts bare assert, error, and throw statements into typed exceptions with Expected, Got, and Suggestion sections.
• Early Validation: Adds guards at API boundaries to catch invalid inputs before they reach numerical routines.
• Loop Context Preservation: Includes iteration indices and per-iteration state in errors thrown inside loops so users can reproduce failures without debug prints.
• Exception Chaining: Preserves original exception types and messages when catching and re-throwing to retain root causes.

Quick Start

Use the error-message-manager skill to audit Julia source files and rewrite vague error messages into structured diagnostics with Expected, Got, and Suggestion sections.
