SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Manually writing, refactoring, and reviewing code across multiple repositories is time‑consuming and error‑prone. This Skill automates those coding tasks by delegating them to the OpenAI Codex CLI, streamlining feature development, bug fixes, and PR reviews.

Core Features & Use Cases

One‑Shot Tasks: Quickly implement a feature or fix a bug with a single Codex command.
Background Mode: Run long‑running refactoring or batch operations in the background and monitor progress.
PR Reviews: Automatically generate code reviews inside a temporary Git workspace.
Parallel Issue Fixing: Use Git worktrees to fix multiple issues concurrently with Codex.
Batch PR Reviews: Fetch and review multiple pull requests in parallel.

FAQPage Schema

How do I automate code reviews for pull requests in a Git repository?▼

Automated PR reviews are handled by generating code reviews inside a temporary Git workspace. The Skill delegates the review process to the Codex CLI to analyze pull requests and produce feedback automatically.

Can I fix multiple Git issues concurrently using Codex?▼

Parallel issue fixing uses Git worktrees to resolve multiple issues concurrently with Codex. This allows the Codex CLI to operate on several isolated branches simultaneously, speeding up batch bug fixes.

How do I run long-running refactoring tasks in the background?▼

Background mode executes long-running refactoring or batch operations in the background and monitors progress. This delegates extended code transformations to the Codex CLI without blocking the terminal.

What do I need to automate coding tasks with the Codex CLI?▼

Automating coding tasks requires the Codex CLI installed, an OpenAI API key, and execution inside a Git repository with PTY support. These prerequisites allow the tool to interface with the repository.

How do I implement a feature or fix a bug with a single command?▼

One-shot tasks quickly implement a feature or fix a bug with a single Codex command. This sends a direct instruction to the Codex CLI to generate the required code changes immediately.

Does batch PR review fetch and review multiple pull requests at once?▼

Batch PR reviews fetch and review multiple pull requests in parallel. This automates the review cycle by delegating multiple pull requests to the Codex CLI simultaneously for concurrent analysis.
