What problem does it solve?
Codex removes the manual overhead of implementing features, performing large-scale refactors, and conducting PR reviews by delegating coding tasks to an autonomous CLI agent that can make, test, and commit changes in a git workspace.
Core Features & Use Cases
- Autonomous Coding: Run one-shot or long-running Codex sessions to implement features, add tests, or perform large refactorings inside a repository.
- PR Review & Batch Fixes: Safely review pull requests in temporary clones or run parallel worktrees to fix many issues concurrently and create PRs for each branch.
- Background/Interactive Modes: Support interactive PTY sessions for live tasks and background sessions with monitoring, logging, and the ability to submit inputs or kill sessions as needed.
- Use Case: Launch Codex in a worktree to fix an assigned issue, monitor progress, then push and open a PR when complete.
Quick Start
Ask the agent to run codex exec --full-auto "Refactor the auth module" inside your project repository with pty enabled and monitor the session until it completes.
