🧵How to Maximize the Value of Codex

1/🧭 Jason Liu Redefines Knowledge Work with Codex

A Codex team DX engineer and founder of Instructor, Jason says: Codex is not just about writing code

It has become the core hub for handling slides, PDFs, and spreadsheets across tool boundaries. 👇 https://t.co/UwrB8wkCAC

2/ He pins a thread for each core workflow

Staff threads, Agent SDK, open-source Codex… these are not chat logs,

but “persistent threads” that accumulate months of preferences, decisions, and context — the agent never needs to start over when it returns.

3/ The value of voice input isn’t speed, it’s rawness

The agent gets Jason’s unedited raw thoughts, not a polished version.

“I remember Ben mentioned this on Slack, go check it out” — typing is too cumbersome, but saying it out loud is incredibly natural.

4/ The “pivot” feature lets him direct while watching, no waiting

While previewing a website, he says aloud: shrink it, there’s a typo, spacing is off, submit a PR, wait for deployment, send to Slack for review…

The agent executes while he’s already moved on; a queue has formed.

5/ He built his memory system on top of an Obsidian Vault

The repository stores code, the Vault stores dynamic context: people, decisions, project status.

The agent updates the Vault, Jason reviews the diff — this audit step is critical to prevent memory bias from silently accumulating across conversations.

6/ Heartbeat mechanism: letting loops run automatically across tool boundaries

His staff thread checks Slack and Gmail every 30 minutes, with draft replies already waiting in his drafts.

Animation project case: heartbeat monitors Slack feedback → re-render → auto-reply tagging reviewers. He’s not there, but the loop keeps running.

7/ The only change he truly cares about comes down to one sentence:

Work shouldn’t pause when you step away.

Threads keep running, memory keeps updating, feedback keeps being processed — even while you take a shower, the refund is already done.

This is what an AI agent should look like.
