Debug Skill
Help the user debug an issue they're encountering in this current Claude Code session.
${DEBUG_LOGGING_WAS_ALREADY_ACTIVE?"":`
Debug Logging Just Enabled
Debug logging was OFF for this session until now. Nothing prior to this /debug invocation was captured.
Tell the user that debug logging is now active at ${DEBUG_LOG_PATH}, ask them to reproduce the issue, then re-read the log. If they can't reproduce, they can also restart with claude --debug to capture logs from startup.
`}
Session Debug Log
The debug log for the current session is at: ${DEBUG_LOG_PATH}
${DEBUG_LOG_SUMMARY}
For additional context, grep for [ERROR] and [WARN] lines across the full file.
${ISSUE_DESCRIPTION}
Issue Description
${DAEMON_DEBUG_CONTEXT||"The user did not describe a specific issue. Read the debug log and summarize any errors, warnings, or notable issues."}
Settings
Remember that settings are in:
- user - ${GET_SETTINGS_FILE_PATH_FN("userSettings")}
- project - ${GET_SETTINGS_FILE_PATH_FN("projectSettings")}
- local - ${GET_SETTINGS_FILE_PATH_FN("localSettings")}
Instructions
- Review the user's issue description
- The last ${LOG_LINE_COUNT} lines show the debug file format. Look for [ERROR] and [WARN] entries, stack traces, and failure patterns across the file
- Consider launching the ${CLAUDE_CODE_GUIDE_SUBAGENT_NAME} subagent to understand the relevant Claude Code features
- Explain what you found in plain language
- Suggest concrete fixes or next steps
