The Scheduler CLI enables 24/7 autonomous agent operations by running agents at regular intervals.

Quick Start

With Direct Prompt (No YAML needed)

# Schedule with a simple prompt
praisonai schedule "Check AI news and summarize" --interval hourly

With agents.yaml

# Schedule using agents.yaml configuration
praisonai schedule agents.yaml

Installation

pip install praisonai praisonaiagents
export OPENAI_API_KEY=your_key_here

PM2-Style Daemon Commands

# With all options
praisonai schedule start my-agent "Monitor logs" \
  --interval "*/30m" \
  --timeout 120 \
  --max-cost 2.00 \

Legacy Foreground Mode

For quick testing or one-off runs, use foreground mode:

# Direct prompt (runs in foreground)
praisonai schedule "Your task" --interval hourly

# YAML mode (runs in foreground)
praisonai schedule agents.yaml

YAML Configuration Example:

framework: praisonai

agents:
  - name: "AI News Monitor"
    role: "Technology News Analyst"
    goal: "Monitor and summarize AI news"
    instructions: "Search for latest AI developments"
    tools:
      - search_tool
    verbose: true

task: "Search for latest AI news and provide top 3 stories"

schedule:
  interval: "hourly"
  max_retries: 3
  run_immediately: true
  timeout: 60
  max_cost: 1.00

Run YAML in foreground:

praisonai schedule agents.yaml

Press Ctrl+C to stop. Shows final statistics:

Execution stats - Total: 12, Success: 11, Failed: 1
Total cost: $0.0056
Runtime: 3600.5s

Storage Locations

State files: ~/.praisonai/schedulers/*.json
Log files: ~/.praisonai/logs/*.log

Features

✅ PM2-style daemon management - No nohup needed
✅ Process persistence - State saved to disk
✅ Easy lifecycle control - start/stop/restart/list
✅ Centralized logging - Auto-rotation, follow mode
✅ Graceful shutdown - SIGTERM with SIGKILL fallback
✅ Cost monitoring - Budget limits with $1.00 default

Schedule Intervals

Format	Interval	Description
`hourly`	3600s	Every hour
`daily`	86400s	Every 24 hours
`*/30m`	1800s	Every 30 minutes
`*/6h`	21600s	Every 6 hours

  --timeout 120

Save Configuration

# Export scheduler config to YAML
praisonai schedule save <name> [output.yaml]

# Example
praisonai schedule save news-bot news-config.yaml

Command Reference

Daemon Commands

Command	Description	Example
`start <name> "task"`	Start scheduler as daemon	`praisonai schedule start my-bot "Task"`
`list`	List all schedulers	`praisonai schedule list`
`logs <name> [--follow]`	View logs	`praisonai schedule logs my-bot --follow`
`stop <name>`	Stop scheduler	`praisonai schedule stop my-bot`
`restart <name>`	Restart scheduler	`praisonai schedule restart my-bot`

Options

Option	Type	Description	Default	Example
`--interval`	string	Schedule interval	`hourly`	`hourly`, `*/30m`, `daily`
`--max-retries`	int	Max retry attempts	`3`	`3`, `5`
`--timeout`	int	Max execution time (seconds)	`None`	`60`, `120`

Example 2: News Monitoring with YAML (Advanced)

agents.yaml:

framework: praisonai

agents:
  - name: "AI News Monitor"
    role: "Technology News Analyst"
    instructions: "Search and summarize latest AI news"
    tools:
      - search_tool

task: "Search for latest AI news and provide top 3 stories"

schedule:
  interval: "hourly"
  max_retries: 3
  run_immediately: true

Run:

praisonai schedule agents.yaml

Example 2: Data Collection (Every 30 Minutes)

agents.yaml:

framework: praisonai

agents:
  - name: "Data Collector"
    role: "Data Analyst"
    instructions: "Collect and analyze market data"
    tools:
      - search_tool

task: "Collect latest market data and identify trends"

schedule:
  interval: "*/30m"
  max_retries: 5
  run_immediately: false

Run with override:

# Override to run every 15 minutes instead
praisonai schedule agents.yaml --interval "*/15m"

Example 3: With Budget and Timeout Limits

agents.yaml:

framework: praisonai

agents:
  - name: "Budget-Controlled Agent"
    role: "Worker"
    instructions: "Process data efficiently"
    tools:
      - search_tool

task: "Process and analyze data"

schedule:
  interval: "*/5m"
  max_retries: 3
  run_immediately: true
  timeout: 120              # Max 2 minutes per execution
  max_cost: 0.50            # Stop after $0.50 spent

Run:

praisonai schedule agents.yaml --verbose

Output:

Budget limit: $0.50
Timeout per execution: 120s
...
Estimated cost this run: $0.0002, Total: $0.0002
Budget remaining: $0.4998
...
Budget limit reached: $0.5001 >= $0.50
Stopping scheduler to prevent additional costs

Example 4: Testing with Short Interval

# Test with 10-second interval
praisonai schedule agents.yaml --interval "*/10s" --verbose

Python API

For programmatic control, use the Python API:

Option 1: Load from agents.yaml

from praisonai.scheduler import AgentScheduler

# Load from YAML
scheduler = AgentScheduler.from_yaml("agents.yaml")

# Start with YAML config
scheduler.start_from_yaml_config()

# Or override settings
scheduler = AgentScheduler.from_yaml(
    "agents.yaml",
    interval_override="*/15m",
    max_retries_override=5
)
scheduler.start_from_yaml_config()

# Keep running
try:
    while scheduler.is_running:
        import time
        time.sleep(1)
except KeyboardInterrupt:
    scheduler.stop()
    print(scheduler.get_stats())

Option 2: Create Programmatically

from praisonaiagents import Agent
from praisonai.scheduler import AgentScheduler

# Create agent
agent = Agent(
    name="NewsChecker",
    instructions="Check latest AI news",
    tools=[search_tool]
)

# Create scheduler
scheduler = AgentScheduler(
    agent=agent,
    task="Search for latest AI news"
)

# Start (runs every hour)
scheduler.start("hourly", max_retries=3, run_immediately=True)

# Keep running
try:
    while scheduler.is_running:
        import time
        time.sleep(1)
except KeyboardInterrupt:
    scheduler.stop()
    print(scheduler.get_stats())

Features

Core Features

Interval-based scheduling: Run agents at regular intervals
Background execution: Runs in daemon thread, won’t block terminal
Automatic retry: Retry failed executions with exponential backoff (30s, 60s, 90s)
Graceful shutdown: Clean stop with Ctrl+C
YAML configuration: Simple configuration in agents.yaml
CLI overrides: Override any setting from command line

Safety Features

⏱️ Timeout Protection: Prevent runaway executions (Unix/Linux/Mac only)
💰 Cost Monitoring: Real-time cost tracking with budget limits
📊 Statistics Tracking: Monitor execution success rates, costs, and runtime
🛡️ Budget Protection: Auto-stops when cost limit reached
🔄 Retry Logic: Exponential backoff prevents rapid failures

Output

The scheduler provides detailed logging with cost tracking:

Starting agent scheduler: AI News Monitor
Task: Search for latest AI news
Schedule: hourly (3600s interval)
Timeout per execution: 60s
Budget limit: $1.00
Agent scheduler started successfully

[2025-12-22 10:00:00] Starting scheduled agent execution
Attempt 1/3
Agent execution successful on attempt 1
Result: [agent output]
Estimated cost this run: $0.0001, Total: $0.0001
Budget remaining: $0.9999
Next execution in 3600 seconds (1.0 hours)

Statistics

Get execution statistics:

stats = scheduler.get_stats()
# Returns:
{
    "is_running": True,
    "total_executions": 10,
    "successful_executions": 9,
    "failed_executions": 1,
    "success_rate": 90.0,
    "total_cost_usd": 0.0045,
    "runtime_seconds": 3600.0,
    "cost_per_execution": 0.0005
}

On stop (Ctrl+C)

🛑 Stopping scheduler… 📊 Final Statistics: Total Executions: 5 Successful: 5 Failed: 0 Success Rate: 100.0% ✅ Agent stopped successfully

## Error Handling

The scheduler automatically retries failed executions with exponential backoff:

- **Attempt 1:** Execute immediately
- **Attempt 2:** Wait 30s, retry
- **Attempt 3:** Wait 60s, retry
- **Attempt 4:** Wait 90s, retry
- **Attempt 5:** Wait 120s, retry

## Stopping the Scheduler

Press `Ctrl+C` to stop gracefully. The scheduler will:
1. Set stop event
2. Wait for current execution (max 10s)
3. Log final statistics
4. Exit cleanly
