Codex 没有内置创建 worktree 的功能。
让写代码的代理审查自己的 diff，它会将写代码时的假设一起带入审查，难以发现自己忽略的问题。
异源模型互审（如 Claude 写的代码由 Codex 审查）能提升问题发现率，但不能提升正确率，审查意见仍可能误报。
Codex does not just generate text replies, but directly operates the computer to read files, organize data, and generate reports, making it a typical Agent form.
Codex supports scheduled tasks, so users can set up work in advance and Codex completes it asynchronously while the user rests.
Codex can handle cross-format information extraction, for example reading line items from a PDF invoice and extracting the data.
Codex's desktop pet feature displays all currently executing tasks, and clicking the pet jumps to the corresponding task progress interface, and it also supports changing the appearance.
Codex's default mode shows a large amount of technical detail, and switching to "Everyday Work" mode hides the technical noise while retaining all capabilities.
To use Gemini 4 Argon in tools such as Claude Code, Codex and Cursor, you need to install the latest version of Vercel CLI and run the vercel ai-gateway setup command.
herdr does not wrap coding agents, it only manages their terminals, and supports many agents such as Claude Code, Codex, Gemini, Cursor, and OpenCode.

90%VerifiedOpenAI Codex is the underlying engine for products such as GitHub Copilot.
90%VerifiedOpenAI Codex was originally released in 2021 as a code generation model fine-tuned on GPT-3 and was the core engine behind GitHub Copilot
90%VerifiedCodex supports dozens of programming languages including Python, JavaScript, TypeScript, Go, and Ruby.
90%VerifiedGitHub Copilot is built on OpenAI's Codex model, which is a code-specialized fine-tuned version of GPT-3 trained on tens of billions of lines of public code.

90%VerifiedCodex excels at tasks such as function-level code completion, module architecture generation, and documentation-to-code conversion.
90%VerifiedOrdinary office workers should prioritize using WorkBuddy to get work done, and only advance to learning Codex when it is no longer sufficient, in order to reduce the learning cost.
80%VerifiedWorkBuddy works out of the box without requiring environment configuration or command-line setup, making it beginner-friendly; Codex requires stronger hands-on ability and a programming background.
80%VerifiedWorkBuddy is positioned as a domestic alternative to Codex.
80%VerifiedDeepSeek Harness is written in TypeScript, and installation requires a Node.js environment (tested with Node.js 24).
80%VerifiedAgents possess a 'plan–execute–feedback' loop capability, can call external tools such as web search, databases, and APIs, and can decompose complex tasks.
80%VerifiedCodex CLI can read local codebases, execute shell commands, edit files, and run tests.
80%VerifiedPass rates of code generation models on benchmarks such as HumanEval jumped from 60% to over 90% between 2024 and 2025
80%VerifiedCodex CLI is a command-line programming tool launched by OpenAI that allows developers to interact directly with AI models in the terminal to complete coding tasks.
80%VerifiedCodex first appeared in 2021 as the underlying engine of GitHub Copilot.
