What is gtm-fix-guide?
Plain-language fix guide for failing GTM tests. Use when tests have failed and the developer needs step-by-step instructions to fix each issue. Reads gtm-test-results.json and writes a fix guide in plain English - no GTM expertise required to follow. No API calls. Trigger on - "fix guide", "how do I fix failing tests", "tests failing", "gtm test failures", "fix my tracking", "what broke". Source: aimonk2025/google-tag-manager-automation.
