Run Summary Feature - Implementation Plan

Overview

The Run Summary feature provides users with a consolidated view of what happened in their session while they were away. It tracks significant events, issues, and statistics, presenting them in an easy-to-digest format.

Data Structures

RunSummaryEventType

type RunSummaryEventType =
  | 'session_started'
  | 'session_stopped'
  | 'respawn_cycle_started'
  | 'respawn_cycle_completed'
  | 'respawn_state_change'
  | 'error'
  | 'warning'
  | 'token_milestone'
  | 'auto_compact'
  | 'auto_clear'
  | 'idle_detected'
  | 'working_detected'
  | 'ralph_completion'
  | 'ai_check_result'
  | 'hook_event'
  | 'state_stuck';

RunSummaryEvent

interface RunSummaryEvent {
  id: string;
  timestamp: number;
  type: RunSummaryEventType;
  severity: 'info' | 'warning' | 'error' | 'success';
  title: string;
  details?: string;
  metadata?: Record<string, unknown>;
}

RunSummary

interface RunSummary {
  sessionId: string;
  sessionName: string;
  startedAt: number;
  lastUpdatedAt: number;
  events: RunSummaryEvent[];
  stats: {
    totalRespawnCycles: number;
    totalTokensUsed: number;
    peakTokens: number;
    totalTimeActiveMs: number;
    totalTimeIdleMs: number;
    errorCount: number;
    warningCount: number;
    aiCheckCount: number;
    lastIdleAt: number | null;
    lastWorkingAt: number | null;
    stateTransitions: number;
  };
}

Event Sources

Event Type	Source	Trigger
session_started	Session	startInteractive() / startShell()
session_stopped	Session	stop()
respawn_cycle_started	RespawnController	State → sending_update
respawn_cycle_completed	RespawnController	State → watching (after cycle)
respawn_state_change	RespawnController	Any state transition
error	Various	Errors caught in try/catch
warning	RunSummaryTracker	State stuck > 5min, high tokens
token_milestone	Session	Every 50k tokens
auto_compact	Session	autoCompact event
auto_clear	Session	autoClear event
idle_detected	Session	idle event
working_detected	Session	working event
ralph_completion	RalphTracker	completionDetected event
ai_check_result	RespawnController	AI check completes
hook_event	Server	/api/hook-event endpoint
state_stuck	RunSummaryTracker	Same state > 10min

API Endpoint

GET /api/sessions/:id/run-summary

Returns the full run summary for a session.

Response:

{
  "success": true,
  "summary": {
    "sessionId": "...",
    "sessionName": "...",
    "startedAt": 1234567890,
    "lastUpdatedAt": 1234567890,
    "events": [...],
    "stats": {...}
  }
}

UI Design

Summary Modal

• Header: Session name, duration, status indicator
• Stats Cards Row:
  • Respawn Cycles: count
  • Tokens Used: peak / current
  • Active Time: formatted duration
  • Issues: errors + warnings count
• Timeline:
  • Vertical timeline of events
  • Color-coded by severity (green=success, blue=info, yellow=warning, red=error)
  • Expandable details
  • Filter by event type
• Footer: "Close" button

Implementation Steps

1. Add types to types.ts
2. Create run-summary.ts with RunSummaryTracker class
3. Integrate tracker with server.ts (create per session, wire events)
4. Add API endpoint
5. Add frontend modal and button
6. Test with live session

Storage

Run summaries are kept in memory only (not persisted to disk) since:

• They're session-specific and regenerated on session start
• Persisting thousands of events would bloat state.json
• Server restart = fresh session anyway

If persistence is needed later, could add to state-inner.json with per-session limits.
