The GPT-5 Consultant skill is designed to break through 'circular debugging' cycles where standard troubleshooting fails to yield results. By leveraging the gpt5-mcp-server, it gathers comprehensive conversation context—including the timeline of failed attempts, full error logs, and system constraints—and presents it to a high-reasoning model for a third-party audit. This skill is ideal for resolving obscure edge cases, making high-stakes architectural choices, or navigating novel technical challenges where traditional documentation is insufficient, effectively acting as a senior technical lead for your development environment.
