CodexAI ProgrammingCodex is OpenAI's AI coding agent for software engineering tasks. The official documentation currently covers Codex CLI, IDE extensions, desktop workspaces, and Codex cloud: the CLI can inspect files, modify code, and run commands in local repositories; cloud tasks run in isolated environments, can proceed in parallel, and can be initiated from GitHub, GitLab, Linear, or Slack; users can review summaries and diffs, request further changes, or create pull requests. Codex is suitable for codebase understanding, feature development, bug fixing, testing, and review, but it does not replace project testing, access controls, or human merge processes. When working with real repositories, secrets, and network operations, access should be scoped first.1129.3All tools with this tag are shown.
