Codex create-plan for a Read-Only Implementation Checklist
Turn a proposed code change into scoped, ordered actions and record decisions that still need confirmation. The workflow is useful for planning a change that needs test and rollout checks before edits begin.
中文Install in Codex
Codex with read access to the target project, including its README and test instructions.
- Copy the pinned `create-plan/` directory into `.agents/skills/create-plan/` at the target repository root.
- Open Codex in the target project and invoke `$create-plan` with the proposed change.
Example task
In a project with a CSV export, ask `$create-plan` to add an export-date column at the end while keeping all existing column positions. Include the compatibility checks needed for existing report readers.What to check
The plan identifies the date format, the exporter, a fixture-based regression check, and the expected result for existing readers. Project files stay read-only during planning.
