error-troubleshooter

What problem does it solve?

This Skill proactively tackles both explicit errors (like stack traces) and insidious "silent failures" where code runs but doesn't produce the expected outcome. It eliminates the need for manual, reactive troubleshooting, saving you time and preventing issues from escalating into larger problems.

Core Features & Use Cases

• Proactive Investigation: Automatically triggers on unexpected behavior or errors, initiating diagnosis without explicit user command, ensuring issues are caught early.
• Dual-Mode Troubleshooting: Handles both explicit failures (e.g., stderr, exceptions) and subtle anomalies (e.g., missing expected effects, wrong output, silent failures).
• Systematic Diagnosis: Employs error template extraction, hypothesis testing, and web research to pinpoint root causes efficiently, even for Stack Overflow-worthy issues.
• Use Case: If your script completes without an error, but a file it was supposed to create is missing, or a configuration change didn't take effect, this skill will automatically investigate the discrepancy, research potential causes, and propose a solution, allowing you to rest.

Quick Start

"My command succeeded, but the expected output file was not generated. Activate the error-troubleshooter skill to investigate this silent failure."
