Pull Request Overview

This PR adds a new cleanup feature that automatically deletes exported .env files after the GitHub Action workflow completes. The implementation introduces a post-execution script that runs after the main action finishes.

Key changes:

• Adds a new clean input parameter (defaults to true) to control whether exported .env files should be deleted
• Implements a post-processing script (post.ts) that handles file cleanup
• Updates the build configuration to compile both main and post scripts

These nested try-catch blocks are unnecessary and make the code harder to read. The inner try-catch (lines 13-19) already handles file access errors gracefully, so the outer try-catch (lines 10-22) that wraps it provides no additional value. Consider removing the outer try-catch block and keeping only the inner one.

The cleanup logic should only execute when export-type is set to "file". Currently, the post script attempts to clean up the file regardless of the export type. When export-type is "env", no file is created (secrets are only set as environment variables in index.ts), so attempting cleanup is unnecessary and could log misleading debug messages. Add a check for export-type before attempting cleanup:

const exportType = core.getInput("export-type");
if (shouldClean && exportType === "file") {
  // cleanup logic
}
