# Codex browser and computer use: saving flows as skills you can schedule

▶

Nate Herk walks through Codex's in-app browser and its separate computer-use plugin end to end — annotating broken UI elements by clicking them, turning a browser agent loose to try to break a local app, and capturing a login-gated download flow as a reusable skill that can then be attached to a scheduled routine. The most useful part is the restraint: he lays out a three-step decision ladder for when browser automation is the wrong tool, and is blunt that the real time saving on any single flow is five to ten minutes. Codex here is OpenAI's coding agent, so this feeds our [ChatGPT hub](https://openclawdatabase.com/chatgpt/).

## Step-by-Step Breakdown

1. **Open the Codex desktop app and bring up the in-app browser**
 The browser opens in a right-hand pane alongside the chat, so you can drive it yourself — search, follow links — while Codex is open. When Codex takes control, its cursor appears as a separate pointer from yours, which is how you know the agent is driving rather than you.
2. **Fix UI problems by annotating elements instead of describing them**
 Click the *annotate* button, then click the specific element you want changed — in the demo, a phone-number box overlapping the company field — and type what is wrong with it. Each annotation lands in the chat as a queued item. Add several (a second one for a box misaligned on the Y axis against fields one and three), then fire them all off together. This is the same interaction pattern as a design-mode tool, but running against your own local app.
3. **Point the browser agent at a running app and ask it to break things**
 With a form-submission app running on localhost, the instruction was simply: the UI is open, make sure there are no bugs, use your browser use and test the heck out of this thing, try your best to break it, and report what needs fixing. The agent clicked through the flow, tripped the required-field validation ("first name is required", "enter a valid email address", "enter a 10-digit phone number"), filled the fields, and continued. It then switched itself to mobile view and found responsiveness failures the author had not tested.
4. **Read the findings as data-integrity bugs, not just click failures**
 The agent reported that the core click path mostly worked but flagged two real data-integrity problems: invalid contact data was getting through, and changing the country code to UK reset it to US when returning to edit. It then said it was moving on to keyboard submission and restart behaviour, "which often exposes bypasses the click path misses" — a genuinely different attack surface from clicking.
5. **Choose headless or headed for the run**
 Headless runs the browser in the background so you can keep working in the foreground and never see it; headed lets you watch it move. Ask for headless explicitly when you want a long sweep to run for hours without taking over your screen.
6. **Extend a sweep that stopped too early with a goal**
 The first QA run finished quickly. To push it further, the fix was a `/goal` instruction telling it not to stop until it had tried 100 unique UI edge-case scenarios and then report back.
7. **Sign in once and let Codex keep the session**
 For most sites, signing in manually one time is enough — Codex saves the session and later chats find you already logged in. In the demo a brand-new chat opened X and was already authenticated as the author, and the same held for school portals and Instagram. Secure platforms are the exception (see the errors section).
8. **Capture the flow as a skill, then attach it to a schedule**
 The Relay statement download — go to the dashboard, click accounts, find statements, select two accounts, download them as CSVs, save them into a specific folder — was described once in plain natural language and completed on the first try, then saved as a skill. Because it is a skill, it can be attached to a scheduled routine ("use this skill on the most recent month's statement"). No Loom recording or annotated screenshots were needed; a clear description was enough.
9. **Install computer use separately, as a plugin**
 Computer use is not on by default. Go to plugins, type "computer use", hit install. The distinction is scope: browser use covers things in a browser, computer use covers your actual machine — system settings and desktop apps. While it is active the screen picks up a blue hue around the edges, so it is visually obvious the agent has your desktop.
10. **Chain skills rather than chasing single-task time savings**
 The closing argument is that any one of these saves maybe five to ten minutes. The value is that a library of browser-use skills lets you fire one off and return to what you were doing, and that chaining them into pipelines compounds — the demo's X-article skill opened a YouTube video, took screenshots of specific moments, drafted the article, opened X, created a draft, pasted the content and dragged the images into position.

## Commands & Code Shown

### `/goal`

```
/goal don't stop until you've tried 100 different unique scenarios
of UI edge cases, and then come back to me
```

**Purpose:** Sets an explicit completion condition for a browser-use run instead of letting the agent decide it has done enough.

**When to use:** When a QA sweep terminates earlier than you want. The default run in the demo found real bugs but stopped well short of exhaustive; the goal is what turns it into a long-running sweep.

### Password manager CSV import

```
name,URL,username,password,notes
```

**Purpose:** Codex's settings include a password manager for the in-app browser. You import a CSV with these columns and Codex fills login forms from it, so credentials never get typed into the chat history.

**When to use:** Only for sites that invalidate saved sessions and force re-authentication. See the caveats below before pointing this at anything financial.

## Common Errors & Fixes Covered

Error: "Relay is open at the login screen, but you have to sign in again"

**Why it happens:** Codex saves browser sessions for most sites, but secure platforms — banking is the example — deliberately expire them and boot you out. The saved-session shortcut that makes X or Instagram skills work does not hold there, so a scheduled run arrives at a login wall.

**Fix:** Import the credentials into Codex's built-in password manager (settings → password manager → import a CSV of `name, URL, username, password, notes`) so the browser can fill the form without the values entering chat history. Re-run the skill afterwards. This does not solve two-factor: if the site sends a code to your phone, the run stops there and you finish it by hand.

Error: computer use refused to change a Bluetooth setting

**Why it happens:** Bluetooth access is classified as a privacy permission, and computer use will not take privacy-sensitive actions on your behalf. It also announced up front that it would stop if Windows asked for an admin password or presented a security-sensitive permission it could not safely interpret.

**Fix:** There isn't one, and that is the point — the guardrail is working as designed. Change privacy and security permissions yourself. In the demo the agent recovered by opening the target app and toggling the equivalent in-app setting instead, having initially confused an in-app setting for a system one.

## Gotchas & Caveats

- **Work down the ladder: API, then macro, then browser use.** Reach for an API first — fastest, usually cheapest, and by far the most consistent. If there is no API but the clicks land in the same place every time, write a deterministic macro script instead: a mouse that does not need to reason about what is on screen is cheaper and safer. Only when vision or reasoning is genuinely required does browser use earn its place. Herk estimates an API handles about 95% of what people actually want to automate.
- **Watch a high-stakes skill run about ten times before trusting it.** His own advice on the banking flow is that the way he demoed it — one natural-language description, one run, done — is not how you should do it. Run the skill repeatedly while watching closely, and make the skill's script strict, because the agent is deciding what to click from vision and can go wrong in ways a fixed macro cannot.
- **Two-factor prompts break unattended runs.** He notes that if the code arrives on the same machine, computer use could technically complete the loop — and immediately flags that you probably want to be careful about automating that.
- **Some of the demo's UI bugs were planted.** He asked the app to include a few visual defects so he could demonstrate annotations. Don't read those as a measure of Codex's build quality.
- **Browser use is not always the more expensive path.** The X-article flow could have used the X API, but that bills per use while browser use rides the existing Codex subscription — and he found the API awkward for formatting and for attaching media.
- **Honest expectations on payback.** Five to ten minutes saved per flow, by his own estimate. The argument for building them is reduced context switching and the ability to chain skills, not headline hours saved.

## Key Takeaways

- Codex's browser agent runs in a pane inside the desktop app with its own visible cursor, and computer use is a separate plugin you install from the plugins panel.
- A browser agent is a credible QA pass: unprompted mobile-view testing, required-field validation, and data-integrity findings the author hadn't looked for.
- Any browser flow can be saved as a skill from a single natural-language run, and skills can be attached to scheduled routines.
- Sessions persist across chats for ordinary sites; secure platforms expire them, which is what the built-in password manager exists to handle.
- The guardrails are real and visible — a blue screen border during computer use, refusal on privacy permissions, and a stated stop on admin-password prompts.
- The decision ladder matters more than the demo: API first, deterministic macro second, browser use only when vision and reasoning are genuinely needed.
