Why Your Setup Looks OK But Claude Ignores It

In the world of coding, encountering issues that seem inexplicable can be a common experience. However, with Claude Code, these failures are often not mysteries. Instead, they fall into a small set of recurring patterns. Understanding these patterns can significantly streamline your troubleshooting process, saving both time and frustration.

Common Issues and Quick Diagnostic Commands

After the introduction, the article presents a practical troubleshooting catalog for Claude Code. It starts with four “muscle memory” commands that are crucial for resolving most issues swiftly:

• /doctor: This command helps identify underlying issues that might not be apparent at first glance.
• /context: Use this to ensure the context is set correctly, helping to align the Claude Code environment with your expectations.
• /memory: This checks if there are any memory-related issues affecting performance, particularly useful for large projects.
• /debug: A comprehensive command that provides detailed insights into ongoing processes, revealing hidden errors.

Recurring Categories of Failures

The article then delves into five recurring categories of failures that users often encounter:

• Loading Problems: These issues often arise when files are loaded on demand rather than at startup, such as loading CLAUDE.md.
• Surprise Permissions: Sometimes, request/allow rules can override mode settings unexpectedly, leading to permission issues.
• Delegation Not Triggering: For subagent or skill descriptions to trigger effectively, they need to be specific and trigger-based.
• Integrations Become Silent: This can occur if project-wide configurations are not set correctly. Using commands like /mcp and /hooks can help resolve these.
• Environment Quirks: Issues such as UI/input changes, trust/working tree behavior, and state-related performance issues often fall into this category.

Developing Diagnostic Instincts

The article emphasizes the importance of following a diagnostic order when you’re stuck. Understanding the scope/precedence rule helps in “it should work” situations, and developing diagnostic instincts can be achieved with a “do it today” checklist. This approach ensures that you can diagnose problems in seconds, enhancing your efficiency and effectiveness as a developer.
