Give Codex a reliable project handoff

A new coding session needs facts about the current project. This original instruction template helps you record scope, changed files, test evidence and release boundaries. It works as a reviewed section in project instructions or as a prompt alongside your existing handoff.

Compatibility

Plain Markdown instructions for a Codex project. Merge into existing AGENTS.md after review; not a Claude plugin.

How to use it

Download the Markdown template and compare it with your current AGENTS.md.
Merge only relevant instructions into the project file. Keep more specific security and release rules.
Write a short handoff with the current branch, unfinished work and exact verification commands.
Start a new session and ask it to confirm the handoff against the actual files before editing.

Example

What you get

The next session can identify the current state and run the same checks without guessing.

Limits

This file supplies instructions, not permissions or access to tools.
It does not make model output deterministic. Review code and test evidence.
Do not paste credentials or customer records into a handoff.

Download

The file is our own work, under the MIT license. Download codex-project-handoff.md.

# Project handoff checklist

Before work, read AGENTS.md and the current handoff. Inspect git status and the active branch. Preserve uncommitted work.

Record the objective, current behavior, affected routes and files, relevant commands, and release boundary.

Implement the smallest complete change using existing project patterns. Inspect callers before changing a shared interface.

Run the appropriate local checks. Distinguish source review, unit tests, browser evidence, provider evidence and production behavior.

At handoff, record changed files, commands and results, known failures, next steps and rollback. Never record credentials, tokens or personal customer data.

Do not claim completion while required checks remain unresolved. Do not publish or push to production without explicit authorization.

Status
