CHAT—Logger

Automatically logs every conversation message to workspace/chat/YYYY-MM-DD.md. Creates new files if needed, always appends never overwrites.

activity_logger 📝

A minimal skill for logging conversation messages to daily Markdown files.

Purpose

Automatically log every user message and assistant reply to a daily Markdown file.

What It Does

• Creates one log file per day: workspace/chat/YYYY-MM-DD.md
• Appends each conversation entry to the daily file
• Never overwrites existing data
• Creates directories and files automatically if they don't exist

Log Format

[HH:MM:SS]
User: <message>
Assistant: <reply>

How It Works

The agent should manually log each conversation turn using this logic:

1. Create Daily Log File

const fs = require('fs');
const path = require('path');
const os = require('os');

// Get workspace path
const workspace = process.cwd(); // or your workspace path
const chatDir = path.join(workspace, 'chat');

// Create directory if it doesn't exist
if (!fs.existsSync(chatDir)) {
  fs.mkdirSync(chatDir, { recursive: true });
}

// Get current date for filename
const now = new Date();
const dateStr = now.toISOString().split('T')[0]; // YYYY-MM-DD
const timeStr = now.toTimeString().split(' ')[0]; // HH:MM:SS

const logFile = path.join(chatDir, `${dateStr}.md`);

2. Append Log Entry

// Format log entry
const userMsg = /* get user message */;
const assistantMsg = /* get assistant reply */;

let logEntry = `\n[${timeStr}]\n`;
if (userMsg) {
  logEntry += `User: ${userMsg}\n`;
}
if (assistantMsg) {
  logEntry += `Assistant: ${assistantMsg}\n`;
}

// Append to file
fs.appendFileSync(logFile, logEntry);

3. Example Entry

[14:30:00]
User: Hello, how are you?
Assistant: I'm doing well, thank you for asking!

[14:32:15]
User: What's the weather like today?
Assistant: Let me check the weather for you.

Log Location

workspace/chat/YYYY-MM-DD.md

Example:

C:\Users\user\OpenClawWorkspace\chat\2026-03-07.md

Usage Notes

• This is a manual logging skill - the agent writes to the log file after each response
• The skill doesn't use hooks - it's triggered by agent code
• Each entry is appended with a timestamp
• The file is created automatically on first entry of the day
• Multiple conversations on the same day go to the same file

Integration

To use this skill:

1. Copy the chat/ directory structure to your workspace
2. After each agent response, append the user message and assistant reply to the daily log file
3. Use the format shown above
