How can a developer make sure all file names are updated after a rename?

A developer must audit all code that creates file names. This includes code that builds file names from parts. A simple search for exact text will not find all places where a file name is used.

The rule

A developer must audit all code that creates file names.

This includes code that builds file names from parts. A simple search for exact text will not find all places where a file name is used.

A developer often renames files. This means changing the file name in the code. A simple search for the old file name might miss some uses. Some code builds file names using variables. This is called a dynamic construction. The developer must find these dynamic constructions. The developer must also update the variables that create the file names.

A developer renames a file from `ch01_c01_band.json` to `chapter01_section01_band.json`. The developer searches for `ch01_c01_`. This finds some uses. But another part of the code builds the file name like this: `${chapterCode}_c01_${bandName}_band.json`. The `chapterCode` variable still holds `ch01`. The website then shows an error because it cannot find the file. The developer must change the value of `chapterCode` to `chapter01`.

How can a developer ensure all file name references are updated after a rename, including those built dynamically?

A developer must look for direct text changes. A developer must also look for code that creates file names or paths from parts.

How can a developer ensure consistency when adding new rules or standards?

A developer must check all existing rules that might conflict with a new rule. This is true when the goal is to make many files consistent.

How can a developer make sure files are safe before making changes?

Before a developer makes the first edit in any work session, a backup copy of the file must be made. The backup file name should include the date.

When should an AI model show the full paths of files it has changed?

An AI model must show full file paths after every major update. A major update is any change that modifies one or more files.
