Session Debug

When your Claude Code session goes sideways and you need to understand what actually happened, this pulls the full event chain from Agent Monitor's API and lays it out chronologically. You get the agent hierarchy tree, every tool call with timing, token usage spikes, and gaps in the timeline that suggest something stalled. It highlights errors in context, traces the critical path through events, and spots anomalies like duplicate states or unexpected event ordering. The diagnosis section attempts root cause analysis, which is hit or miss, but having the raw timeline with PreToolUse, PostToolUse, and SubagentStop events in one view beats manually correlating logs. Best used right after a session errors out or when you're debugging why something took forever.
