slack-joke-agent 1.1.2

Daily Slack agent that sends jokes and trivia with MCP

Slack Joke Agent

An agent that sends jokes and trivia to your Slack channel daily.

Features

• AI-Generated Content - Fresh jokes and trivia powered by Claude AI
• Science/tech jokes (60% of messages)
• Science/tech history trivia facts (40% of messages)
• Automated posting at 9:00 AM daily (configurable)
• Uses MCP Slack server integration
• Targets #random channel by default
• Written in Python with robust error handling
• Comprehensive logging to file and console
• Graceful Fallback - Uses predefined content if AI generation fails

Setup

1. Configure environment variables:

   cp .env.example .env
   # Edit .env with your Slack bot tokens
   

   Create a Slack app at https://api.slack.com/apps to get the bot token.

2. Install dependencies:

   pip install -e .
   

3. Or use the startup script:

   ./start-agent.sh
   

4. Ensure MCP Slack server is configured

Usage

Start the daily agent:

python3 slack_agent.py

Start with custom time:

python3 slack_agent.py --time 12:00  # Daily at noon

Test with immediate message:

python3 slack_agent.py --test

Use custom channel:

python3 slack_agent.py --channel C1234567890

Enable verbose logging:

python3 slack_agent.py --verbose

How it Works

1. Scheduling: Uses Python schedule library to trigger daily at 9:00 AM
2. AI Generation: Uses Anthropic's Claude AI to generate fresh content
3. Content Selection: Randomly selects between jokes and trivia (60%/40% split)
4. Fallback System: Uses predefined content if AI generation fails
5. MCP Integration: Spawns the MCP Slack server process
6. Channel: Posts to #random channel by default
7. Logging: Logs to both console and slack_agent.log file

Configuration

Environment variables in .env file:

Required:

• SLACK_BOT_TOKEN - Your Slack bot token (xoxb-...)
• SLACK_TEAM_ID - Your Slack team/workspace ID
• ANTHROPIC_API_KEY - Your Anthropic API key for Claude AI (sk-ant-...)

Optional:

• SLACK_CHANNEL_IDS - Comma-separated list of allowed channels
• DEFAULT_CHANNEL_ID - Default channel to post

Security:

• All secrets loaded from .env file (excluded from git)
• No hardcoded API keys or tokens in source code
• Environment variable validation on startup
• Graceful handling of missing AI credentials

AI Features:

• Dynamic content freshly generated by Claude AI
• Workplace appropriate prompts ensure clean content
• Automatic fallback to predefined content if AI generation fails
• Smart logging tracks AI generation success/failure

Command Line Options

• --test: Send a test message immediately
• --test-ai: Test AI generation without sending to Slack
• --channel CHANNEL_ID: Override the default channel
• --time HH:MM: Set daily schedule time (default: 09:00)
• --verbose, -v: Enable verbose debug logging

Logs

The agent creates comprehensive logs:

• Console output: Real-time status and messages
• File logging: slack_agent.log with detailed information
• Timestamps: All log entries include precise timestamps
• Error tracking: Failed attempts are logged with details

Modify the schedule configuration:

schedule.every().day.at("09:00").do(self.send_daily_message)  # Daily at 9 AM (current)
schedule.every().day.at("12:00").do(self.send_daily_message)  # Daily at noon
schedule.every().hour.at(":00").do(self.send_daily_message)   # Every hour
schedule.every().monday.at("09:00").do(self.send_daily_message)  # Weekly on Monday
