Codex Interaction Library

A comprehensive Python library for interacting with Codex, parsing logs, and managing Codex runs. Each run of Codex is represented as its own class with parsing capabilities for outputs.

Features

• Individual Codex Runs: Each Codex execution is represented as a CodexRun class with complete lifecycle management
• Session Management: Group multiple runs into sessions with CodexSession for batch processing
• Log Parsing: Comprehensive parsing of Codex log files with multiple extraction types
• Template Processing: Jinja2-based template processing for dynamic prompt generation
• CSV Integration: Built-in support for processing CSV data with templated prompts
• File Management: Utilities for backups, file operations, and directory management
• Diff Utilities: Tools for analyzing and displaying file changes
• Pure Interaction Focus: Separated from interface code, focused purely on Codex interaction

Installation

# Install dependencies
pip install jinja2

# The library is designed to be used as a local module
# Copy the codex_interaction directory to your project

Quick Start

Basic Usage

from codex_interaction import CodexRun, CodexSession, CodexLogParser

# Create and execute a single Codex run
run = CodexRun(
    prompt="Create a Python function to calculate fibonacci numbers",
    model="gpt-4.1-nano",
    timeout=300
)

result = run.execute(log_dir="./logs")
print(f"Success: {result.success}")
print(f"Files modified: {result.files_modified}")

Session with Multiple Runs

# Create a session for multiple runs
session = CodexSession(
    session_id="my_session",
    default_model="gpt-4.1-nano",
    log_dir="./logs"
)

# Add multiple runs
session.add_run("Create a calculator class")
session.add_run("Write unit tests for the calculator")
session.add_run("Add documentation to the code")

# Execute all runs
session_result = session.execute_all()
summary = session.get_summary()

CSV Data Processing

from codex_interaction import TemplateProcessor

# CSV data
csv_data = [
    {"file_path": "api/users.py", "method": "GET", "endpoint": "/api/users"},
    {"file_path": "api/orders.py", "method": "POST", "endpoint": "/api/orders"}
]

# Template
template = """
Analyze the API endpoint {{ endpoint }} with method {{ method }} in {{ file_path }}.
Check for security and error handling.
"""

# Process with session
session = CodexSession()
processor = TemplateProcessor()
result = session.process_csv_data(csv_data, template, processor)

Log Parsing

# Parse existing Codex logs
parser = CodexLogParser(log_dir=".", log_pattern="codex_run_*.log")

# Parse all logs
results = parser.parse_logs()

# Parse specific run
run_result = parser.parse_run("codex_run_20241201_123456.log")
print(f"Changes: {len(run_result.changes)}")
print(f"Tool usage: {len(run_result.tool_usage)}")

Library Architecture

Core Classes

• CodexRun: Represents a single Codex execution with full lifecycle management
• CodexSession: Manages multiple Codex runs with batch processing capabilities
• CodexRunResult: Contains complete results from a single run
• CodexSessionResult: Aggregates results from multiple runs

Parsers

• CodexLogParser: Main parser for Codex log files with multiple extraction modes
• CodexOutputParser: Specialized parser for individual command outputs and responses

Extractors

• PatchExtractor: Extracts patch/diff information from logs
• CommandExtractor: Extracts command execution data
• ToolUsageExtractor: Extracts tool usage information
• ChangeDetector: Detects various types of changes
• CustomExtractor: Create custom extraction patterns

Data Models

• CodexChange: Represents detected changes
• PatchData: Represents patch/diff information
• CodexCommand: Represents executed commands
• ToolUsage: Represents tool usage data

Utilities

• TemplateProcessor: Jinja2 template processing for prompts
• FileManager: File operations, backups, CSV handling
• DiffUtils: Diff creation and analysis utilities
• ColorUtils: Terminal color formatting

Advanced Usage

Custom Extractors

from codex_interaction.extractors import CustomExtractor

# Create custom extractor
custom_extractor = CustomExtractor(
    pattern=r'ERROR:\s*(.+)',
    change_type="error"
)

# Use with parser
parser = CodexLogParser()
results = parser.parse_logs(extractors=[custom_extractor])

File Filtering

# Filter by file extension
results = parser.parse_logs()
csv_results = parser.filter_by_file_extension(results, '.csv')

# Filter by change type
patch_results = parser.filter_by_change_type(results, 'patch')

Template Variables

from codex_interaction.utils import TemplateProcessor

processor = TemplateProcessor()

# Convert CSV headers to Jinja variables
headers = ["File Path", "HTTP Method", "Priority Level"]
jinja_vars = processor.convert_csv_headers_to_jinja_vars(headers)
# Result: {"FILE_PATH": 0, "HTTP_METHOD": 1, "PRIORITY_LEVEL": 2}

Design Philosophy

This library is designed with separation of concerns in mind:

1. Pure Codex Interaction: No UI or interface code, purely focused on Codex operations
2. Reusable Components: Each component can be used independently
3. Comprehensive Parsing: Extract all meaningful data from Codex operations
4. Session Management: Support both single runs and batch operations
5. Extensible Architecture: Easy to add new extractors and processors

Use Cases

• Automated Code Analysis: Process multiple files/endpoints systematically
• Log Analysis: Analyze historical Codex operations and results
• Batch Processing: Execute multiple related Codex tasks in sequence
• Template-driven Operations: Use templates to generate consistent prompts
• Integration Projects: Embed Codex interaction into larger systems

Dependencies

• jinja2: Template processing
• Standard library modules: os, re, json, csv, subprocess, tempfile, etc.
