Record and run scripts

Record and run a script that batch-renames layers using the pattern 'Section_Page_Element' from a spreadsheet. Apply it to 'Campaign_Master.ai' so layer names match the client's content spreadsheet. Run the script, save the modified file as 'Campaign_Master_named.ai' and produce a log of original and new layer names.

Before I hand this to content, make the script output easy to verify. Have the script produce a CSV mapping original layer name, new layer name, artboard, and a short preview (first 40 characters of text if a text layer). Highlight any names that would exceed 31 characters or contain non-ASCII characters that will break downstream systems.

I ran a script to rename hundreds of layers from the content spreadsheet, and now several linked assets are missing from the packaged file. I suspect the script altered link paths or renamed layers that scripts elsewhere expected. I must deliver to localization tomorrow. What's the typical cause when renaming layers breaks links, how can I detect which links are actually broken quickly, and what is the safest rollback or repair sequence to restore links without losing the new naming work?

We have a growing library of small scripts each fixing one job: renaming layers, aligning logos, exporting slices. They behave differently on files from different teams and it creates fragile patchwork automation. Which long-term habits or governance will reduce fragility: what testing, documentation, and ownership should we implement so scripts are reliable across files and people stop breaking each other's work?
