What log files does the diagnostic skill analyze?

The skill searches standard locations such as ~/.claude/logs/, ~/.claude.log, and /tmp/claude-* to find relevant error entries and stack traces.

Can this skill fix the problem for me automatically?

While it identifies the root cause and provides recommended fixes, it focuses on diagnosis and documentation; you will typically need to execute the suggested fix manually.

Will this skill leak my API keys in a support ticket?

No, the skill follows strict guidelines to redact sensitive data including API keys, authentication tokens, and internal hostnames before generating any output.

How does it stay updated with the latest Claude Code changes?

It uses WebFetch to retrieve live documentation directly from the official Anthropic troubleshooting index rather than relying on cached model training data.
