How to use Codex to its fullest potential - OpenAI Official Advanced Guide and Core Techniques

Most developers initially use coding Agent It's for processing code: checking the repository, generating differences, running tests, and initiating pull requests.

This remains Codex's core focus. However, a significant amount of work on computers is now mediated by code: executing shell commands, browsing web pages, calling APIs, exporting documentation, responding to events, and triggering...automaticAs these interfaces became available to Codex, it began to feel less like a coding assistant and more like a system that performs computer tasks.

The Codex application makes this transformation concrete. A thread can maintain its context, use tools, display artifacts, and continue across multiple prompts, rather than being reset after each interaction.

To make better use of Codex means combining these capabilities:

• Persistent threads that retain their context
• Voice input, guidance, and queuing used while the user is still in a loop.
• Let Codex transcend the browser, computer usage, MCP server, and connectors of repository operations.
• Threads that continue working when the user leavesautomaticChemicals and Goals
• Users can inspect code, documents, presentations, and other artifacts in the sidebar.

• A chief staff thread
• A publish thread
• A document review thread
• A dedicated thread for external monitoring

I remember someone named Ben on Slack mentioning this. I don't remember the details. Please look it up.

Make this smaller. The spacing between these two elements looks off. This text is wrong.

Once the work is complete, send the preview link to the reviewers on Slack.

• $browser Codex is an in-app browser located in the sidebar, where you can inspect and annotate web pages.
• @chrome Used for logged-in browser status and Chrome-based workflows
• @computer For work that exists only through the desktop GUI

Every 30 minutes, check Slack and Gmail for any unanswered messages that require my attention. Prioritize the most important ones for me. If someone asks me a question, research the answer as thoroughly as possible and draft a reply for me, but don't send it.

• Will ~/vault It is considered as persistent working memory.
• Prioritize using well-structured notes over excessive note-taking.
• Clearly define the routes for TODOs, people, projects, daily summaries, and temporary notes.
• Retain the decision, blocked items, responsible persons, dates, and useful links.
• Don't disturb the warehouse unless there are meaningful changes.
