Programme Objectives

  • Develop functional proficiency in using Codex for software development, application support, troubleshooting, scripting, and technical operations.
  • Build reusable agentic workflows for analysing repositories, implementing changes, debugging issues, testing solutions, and maintaining technical documentation.
  • Apply parallel agents and isolated workspaces to handle complex engineering tasks with stronger separation and review.
  • Use Codex Skills and automation capabilities to standardise recurring IT and development workflows.
  • Apply permissions, security controls, testing, human review, and change-management practices to AI-assisted technical work.

TOC Modules

Concepts
  • Understanding Codex as an agent for writing, reviewing, testing, debugging, and shipping software
  • Understanding Codex across ChatGPT, CLI, IDE, and cloud-based engineering workflows
  • Understanding repository context, command execution, and agentic task completion
Practical activities
  • Connecting Codex with a sample software repository
  • Exploring an application and asking repository-aware technical questions
  • Completing a guided code-analysis and modification task

Scenarios

Application Enhancement to Tested Release

Enhancement Requirement → Repository Analysis → Implementation Plan → Codex Agent → Multi-File Changes → Automated Tests → Code Review → Human Approval → Release

Participants use Codex to analyse an existing application, implement a structured enhancement, validate the change through testing and review, and prepare it for controlled release.

Production Issue to Preventive Automation

Production Issue → Logs & Repository → Codex Investigation → Root Cause → Corrective Change → Regression Tests → Validation → Reusable Skill / Workflow

Participants investigate a simulated production problem, validate a corrective solution, strengthen regression coverage, and convert the proven resolution process into a reusable technical workflow.

*Current Codex supports repository-aware engineering work, command and test execution, code review, parallel agents with isolated worktrees, reusable Skills, and recurring agent workflows, while keeping engineers responsible for reviewing what ultimately ships.*
