You ask to fix the form on the site. A usual advice response still needs to be transferred to the project. Codex can read files, find the form, change code, and run a check. If it

First, check service availability. As of the check date, Russia is absent from the official lists of supported countries for ChatGPT and OpenAI API. OpenAI warns of possible restrictions.

First find where files are and where the task runs. This is more important than button locations: interfaces change, but a wrongly chosen folder remains a real problem.

Choose a task needed in your project. Do not perform the entire list in a row just for a checkmark. Work in a training copy and save the original state. For each task below, specify

You ask to fix the form. Codex changes styles, updates dependencies, and rebuilds navigation at the same time. As a result, half the site must be checked, although the task covered one screen.

Shortening the answer is easy. Reducing total cost for a finished result is harder. If after a short answer you need to clarify a lost requirement three times, compare the entire process

Tools from the catalog solve different tasks. A skill gives Codex instructions, e.g., how to edit text. MCP connects a tool, e.g., note search. The video library helps

Start with the task. For a site, you usually need project rules, browser checks, and chosen hosting. For a video, you need sources, editing software, and export verification. Full install is

For the first project in this book, I choose the application form. It shows whether the site can perform actions: accept correct data, explain errors, and allow retrying

Request 'make it beautiful' does not explain what should stand out, which text to read first, and what action is expected from the visitor. I start with these solutions. Fonts, colors

A working local page solves only part of the task. For a published site, determine where code runs, where data is stored, who has access, and how rec

Start with one user action. For example: open your request list and add a new one. For the first app, you don't need chat, map, subscription, and social network all at once.

A large project is hard to maintain when form, authorization, and data structure change in one request. After an error, it is unclear which solution caused it and which part to revert.

You place source videos in a folder and explain which clip is needed. Codex can find suitable fragments, prepare text, write editing commands, and check the finished file. For

Different methods are needed for cover, intro, and short video. An image can be created by a model from a description. Moving text and diagrams are conveniently assembled from code. For scene,

An item moves through clear stages: facts, writing, production, editing and release checks.

Adapt content to its platform and check an actual preview before posting.

Search needs useful content and accessible pages. Configured settings alone do not prove indexing.

Start with one task, supported facts and a result you can assess.

Test one flow and the access it needs first. An agent does not need access to everything at once.

Choose a repeated action and complete a sample run first.

A clear task, accessible files and result criteria make it easier to continue without unnecessary back-and-forth.

Settings, if needed, are described in thematic chapters and the tool catalog. A separate plugin is not required for a normal state file or design rule.

For any project, create a separate training folder. Save PROJECT_STATE.md, CHECKS.md, and selected versions. First get a small result, then check errors and only
