Proposal: Extend koad:io Logger for AI-Interactive Development

[koad]

Problem

When developing with AI agents (like Vulcan), there's no structured way to:

1. Capture development session logs for later review
2. Stream logs in real-time to another AI agent for live debugging
3. Search/query past development sessions

Solution

Extend ~/.koad-io/packages/core/server/logger.js to write a parallel log file when in development mode.

Implementation Sketch

// In logger.js, add development-mode file logging
const isDev = !Meteor.isProduction && process.env.KOAD_DEV_LOGS === 'true';

if (isDev) {
  const fs = Npm.require('fs');
  const path = Npm.require('path');
  const logFile = path.join(process.cwd(), `dev-session-${Date.now()}.log`);
  
  // Wrap logger methods to also write to file
  const originalInfo = logger.info.bind(logger);
  logger.info = function(...args) {
    originalInfo(...args);
    fs.appendFileSync(logFile, `[\${new Date().toISOString()}] INFO: \${args.join(' ')}\n`);
  };
  // ... same for warn, error, debug
}

Features This Enables

Feature	Use Case
Session replay	Review what happened in a dev session
Live streaming	tail -f dev-session-*.log in another terminal for real-time debugging
Pattern detection	Search logs across sessions for recurring issues
Agent memory	Feed logs to playback-machine for context on past issues

Simple Env Toggle

KOAD_DEV_LOGS=true enables it, off by default.
