How do I find the ID of a failed Claude Code session?

You can use the `/cc-telemetry:sessions` command to display a list of recent sessions, including their unique slugs, timestamps, and status.

Can I see what the AI was thinking before an error occurred?

Yes, this skill specifically analyzes 'thinking blocks' to compare Claude's planned intent against the actual tool inputs and outputs that triggered the error.

Does this skill help with performance issues?

Absolutely. It uses commands like `/cc-telemetry:performance` to highlight tools that took longer than expected, helping you identify bottlenecks like oversized file reads.

What happens if the root cause of an error is still unclear?

The skill includes an escalation path to a specialized telemetry-analyzer agent which can perform deep-dive comparisons across multiple sessions to find systemic patterns.

分析と監視

Diagnoses and troubleshoots failed Claude Code sessions by analyzing tool execution, error logs, and performance metrics.

The session-debugging skill provides a structured diagnostic framework for investigating failures, logic errors, and performance bottlenecks within Claude Code sessions. By leveraging the lore-extensions-cc-telemetry plugin, it enables developers to replay session histories, inspect internal thinking blocks, and trace the exact sequence of tool calls that led to an issue. This skill is indispensable for identifying root causes—whether they stem from environment configurations, invalid tool inputs, or AI reasoning errors—providing clear summaries and actionable fixes to ensure deterministic and repeatable development workflows.
