Internal SmartGift build of a Claude Code monitoring dashboard. Lanes: a durable unit of parallel agent work, one per working directory, tracked across session restarts. Managed lanes are git worktrees the dashboard provisions and can reset or remove behind a three-check destroy guard and a counted preflight; adopted lanes are directories you already own and are never destroyable. Pipelines: a lane moves through pipeline stages. A stage the agent declares with evidence renders green; a stage inferred from the tool-event stream renders dashed amber and never counts as done. Detection is forward-only within a 30-minute window, and never writes the declared stage. Workspace: one page at /run with a lane grid, the selected lane's pipeline, and a full Claude console behind a disclosure.

| Debug a specific session by inspecting its full event chain (PreToolUse, PostToolUse, Stop, SubagentStop, Compaction, APIError, TurnDuration, Notification events), agent hierarchy (recursive parent/child tree with subagent_type and depth), token usage with compaction baselines, workflow intelligence data (orchestration DAG, error propagation by depth), and session metadata (thinking_blocks, turn_count, total_turn_duration_ms). |
Session Debug
Debug and inspect a Claude Code session from Agent Monitor data.
Input
The user provides: $ARGUMENTS
This may be:
- A session ID to debug
- "latest" or "last" for the most recent session
- "errors" to find and debug the most recent errored session
Procedure
-
Identify the target session:
- If session ID given:
GET /api/sessions/{id}fromhttp://localhost:4820 - If "latest":
GET /api/sessions?limit=1(default sort: most recently updated first) - If "errors":
GET /api/sessions?limit=10&status=error
- If session ID given:
-
Collect full session data:
- Session metadata: status, model, cwd, timestamps, duration
- Events:
GET /api/events?session_id={session_id}— full event timeline - Agents:
GET /api/agents?session_id={session_id}— all agents in session - Cost:
GET /api/pricing/cost/{session_id}
-
Analyze the session:
Session Lifecycle
- Start time → first event → last event → end time
- Status transitions (active → working → completed/error)
- Total duration and active-vs-idle time
Event Chain Analysis
- Chronological event list with timestamps and durations
- Identify the critical path (longest chain of dependent events)
- Flag events that took unusually long
- Highlight error events with full error context
Agent Inspection
- List all agents: type, task, status, duration
- Subagent tree visualization (parent → children)
- Agents that failed and their last known state
- Agent switching patterns (when and why new agents spawned)
Tool Execution Trace
- Every tool invocation in order with: tool name, duration, success/failure
- Failed tool calls with error messages
- Tool retry patterns (same tool called multiple times)
Anomaly Detection
- Events out of expected order
- Gaps in event timeline (>30s with no events)
- Duplicate events or agent states
- Token usage spikes (compaction indicators)
-
Diagnosis:
- Root cause hypothesis (if errors present)
- Contributing factors
- Remediation suggestions
Output Format
Present as a debug report with:
- Session summary header (ID, status, model, duration, cost)
- Color-coded timeline (✅ success, ❌ error, ⚠️ warning, ℹ️ info)
- Agent tree diagram
- Diagnosis section with numbered findings
