+## Overview
+This skill enables thorough code review with focus on:
+- Code quality and readability
+- Potential bugs and edge cases
+- Performance considerations
+- Security vulnerabilities
+- Best practices adherence
+
+## Instructions
+
+When reviewing code:
+
+1. **Read the code carefully** - Understand the purpose and flow
+2. **Check for bugs** - Look for null checks, edge cases, error handling
+3. **Evaluate readability** - Variable names, comments, structure
+4. **Consider performance** - Time/space complexity, unnecessary operations
+5. **Security review** - Input validation, injection risks, data exposure
+6. **Suggest improvements** - Provide actionable recommendations
+
+## Output Format
+
+Structure your review as:
+- Summary: Brief overview of the code
+- Issues: List of problems found (severity: high/medium/low)
+- Suggestions: Recommended improvements
+- Positive aspects: What's done well

+# PDF Processing Skill
+
+## Overview
+
+This skill enables agents to process PDF documents, extract text content, and analyze the information within them.
+
+## When to Use
+
+Activate this skill when:
+- User asks to read or analyze a PDF file
+- User needs to extract text from a PDF
+- User wants to summarize a PDF document
+- User needs to search for information within a PDF
+
+## Instructions
+
+1. First, verify the PDF file exists at the specified path
+2. Use appropriate tools to read the PDF content
+3. Extract text while preserving structure where possible
+4. For large PDFs, process in chunks to manage context
+5. Summarize or analyze based on user's specific request
+
+## Best Practices
+
+- Always confirm the file path before processing
+- Handle encrypted PDFs gracefully with appropriate error messages
+- For scanned PDFs, note that OCR may be required
+- Preserve important formatting like tables and lists

+# PraisonAI Scheduler - 24/7 Agent Scheduling
+
+Complete implementation of 24/7 agent scheduling for PraisonAI, enabling autonomous agent operations at regular intervals.
+
+## ✅ Implementation Status
+
+### **Completed Features**
+
+#### 1. **Core Scheduler Module** (`praisonai/scheduler/`)
+- ✅ `base.py` - ScheduleParser, ExecutorInterface, PraisonAgentExecutor
+- ✅ `agent_scheduler.py` - AgentScheduler with full 24/7 capabilities
+- ✅ `__init__.py` - Clean module exports with lazy loading
+
+#### 2. **Schedule Parser**
+Supports multiple schedule formats:
+- `"hourly"` → Every hour (3600s)
+- `"daily"` → Every day (86400s)
+- `"*/30m"` → Every 30 minutes
+- `"*/6h"` → Every 6 hours
+- `"*/5s"` → Every 5 seconds
+- `"3600"` → Custom seconds (3600s)
+
+#### 3. **AgentScheduler Features**
+- ✅ Thread-based execution (daemon threads)
+- ✅ Configurable intervals
+- ✅ Retry logic with exponential backoff (30s, 60s, 90s...)
+- ✅ Success/failure callbacks
+- ✅ Execution statistics tracking
+- ✅ Graceful shutdown with timeout
+- ✅ `run_immediately` option
+- ✅ Thread-safe operation
+
+#### 4. **Testing**
+- ✅ 53 unit tests (100% passing)
+- ✅ 18 tests for base components
+- ✅ 35 tests for AgentScheduler
+- ✅ Real-world testing with live API calls
+- ✅ Verified with OpenAI API and search tools
+
+#### 5. **Backward Compatibility**
+- ✅ Old `scheduler.py` imports from new module
+- ✅ Deprecation warnings added
+- ✅ Existing code continues to work
+
+## 🚀 Quick Start
+
+### Basic Usage
+
+```python
+from praisonaiagents import Agent
+from praisonai.scheduler import AgentScheduler
+
+# Create your agent
+agent = Agent(
+    name="NewsChecker",
+    instructions="Check latest AI news and summarize",
+    tools=[search_tool]
+)
+
+# Create scheduler
+scheduler = AgentScheduler(
+    agent=agent,
+    task="Search for latest AI news and provide top 3 stories"
+)
+
+# Start scheduling (runs every hour)
+scheduler.start(
+    schedule_expr="hourly",
+    max_retries=3,
+    run_immediately=True
+)
+
+# Keep running until stopped
+try:
+    while scheduler.is_running:
+        import time
+        time.sleep(1)
+except KeyboardInterrupt:
+    scheduler.stop()
+    print(scheduler.get_stats())
+```
+
+### With Callbacks
+
+```python
+def on_success(result):
+    print(f"✅ Success: {result}")
+
+def on_failure(error):
+    print(f"❌ Failed: {error}")
+
+scheduler = AgentScheduler(
+    agent=agent,
+    task="Your task",
+    on_success=on_success,
+    on_failure=on_failure
+)
+
+scheduler.start("*/30m")  # Every 30 minutes
+```
+
+### Schedule Formats
+
+```python
+# Predefined intervals
+scheduler.start("hourly")    # Every hour
+scheduler.start("daily")     # Every 24 hours
+
+# Custom intervals
+scheduler.start("*/30m")     # Every 30 minutes
+scheduler.start("*/6h")      # Every 6 hours
+scheduler.start("*/5s")      # Every 5 seconds
+
+# Seconds
+scheduler.start("3600")      # Every 3600 seconds (1 hour)
+```
+
+## 📊 Statistics Tracking
+
+```python
+stats = scheduler.get_stats()
+# Returns:
+# {
+#     "is_running": True/False,
+#     "total_executions": 10,
+#     "successful_executions": 9,
+#     "failed_executions": 1,
+#     "success_rate": 90.0
+# }
+```
+
+## 🔧 Advanced Features
+
+### Retry Logic
+- Automatic retry on failure
+- Exponential backoff (30s, 60s, 90s...)
+- Configurable max retries
+
+```python
+scheduler.start(
+    schedule_expr="hourly",
+    max_retries=5  # Retry up to 5 times
+)
+```
+
+### Immediate Execution
+```python
+scheduler.start(
+    schedule_expr="hourly",
+    run_immediately=True  # Run once before starting schedule
+)
+```
+
+### One-Time Execution
+```python
+result = scheduler.execute_once()  # Execute immediately, no scheduling
+```
+
+### Graceful Shutdown
+```python
+scheduler.stop()  # Waits up to 10 seconds for current execution to finish
+```
+

+## 🎯 Real-World Example
+
+See `examples/python/scheduled_agents/news_checker_live.py` for a complete working example that:
+- Checks AI news every 2 minutes (configurable to hourly)
+- Uses real OpenAI API
+- Uses DuckDuckGo search
+- Displays results with callbacks
+- Tracks statistics
+- Handles Ctrl+C gracefully
+
+## 🔄 Migration from Old Scheduler
+
+Old code continues to work with deprecation warning:

+# Old (still works)
+from praisonai.scheduler import ScheduleParser
+
+# New (recommended)
+from praisonai.scheduler import ScheduleParser
