Codex Security Walkthrough: Plugin Setup, Remediation, and CLI Automation

OpenAI engineer Dan Shanahan demonstrates Codex Security, covering plugin installation, repository scanning with added context, review and remediation of findings, and use of the Codex Security CLI for repeatable security analysis across environments.

■ Codex Security setup
- Access to Daybreak Blue and installation of the Codex Security plugin
- Available skills such as triage and deep scan

■ Scan and remediation workflow
- Selecting a local repository, model, reasoning level, deep scan, and extra context
- Reviewing findings, generating a fix, and opening a pull request in GitHub

■ Scaling with CLI and CI/CD
- Installing the Codex Security CLI via npm
- Running scans and reviewing results from the command line for automation

The plugin workflow is shown on a single local repository, while the CLI section addresses broader automation. The walkthrough suits developers, security engineers, and platform teams evaluating AI-assisted code security. Viewers gain an overview of how Codex Security supports finding, fixing, and automating vulnerability workflows, and can try the process on a familiar codebase.
