# Using PLANS.md for multi-hour problem solving

Codex and the `gpt-5-codex` model can be used to implement complex tasks that take significant time to research, design, and implement. The approach described here is one way to prompt the model to implement these tasks and to steer it towards successful completion of a project.
Codex and the `gpt-5.2-codex` model (recommended) can be used to implement complex tasks that take significant time to research, design, and implement. The approach described here is one way to prompt the model to implement these tasks and to steer it towards successful completion of a project.

These plans are thorough design documents, and "living documents". As a user of Codex, you can use these documents to verify the approach that Codex will take before it begins a long implementation process. The particular `PLANS.md` included below is very similar to one that has enabled Codex to work for more than seven hours from a single prompt.

Luckily, we can replicate Codex's cloud hosted review process in our own CI/CD runners. In this guide, we'll build our own Code Review action using the Codex CLI headless mode with both GitHub Actions and Jenkins.

Model recommendation: use `gpt-5.2-codex` for the strongest code review accuracy and consistency in these workflows.

To build our own Code review, we'll take the following steps and adhere to them closely:
