Failed to delete file ${filePath}: ${error.message}

Error message

Failed to delete file ${filePath}: ${error.message}

What it means

deleteFile() calls fs.unlink and swallows ENOENT (deleting a non-existent file is treated as success), but re-throws any other failure as 'Failed to delete file <path>: <reason>'. This is used for tag deletion cleanup of tag-scoped files.

Solutions

1. Check the OS error in the message and fix accordingly: grant write permission on the file's parent directory (deletion requires directory write access).
2. Close other processes holding the file (editors, sync/backup tools) and retry.
3. If the path is a directory rather than a file, remove it with the appropriate recursive removal instead.
4. Note ENOENT is already tolerated — if you get this error the file exists but is unremovable, so no existence check is needed.

Example fix

// before
rm .taskmaster/tags/feature.json  # rm: permission denied
// after
sudo chown -R $(whoami) .taskmaster
chmod -R u+w .taskmaster

import { stat, access, constants } from 'fs/promises';
import path from 'path';
export async function canDeleteFile(filePath: string): Promise<boolean> {
  try {
    const s = await stat(filePath);
    if (!s.isFile()) return false;
    await access(path.dirname(filePath), constants.W_OK); // dir write permission required to unlink
    return true;
  } catch { return false; }
}

try {
  await fileOps.deleteFile(filePath);
} catch (err: any) {
  if (err.message.startsWith('Failed to delete file')) {
    // ENOENT is already tolerated by the library; this is EACCES/EBUSY/etc.
    console.warn(`Could not delete ${filePath} (${err.message}); leaving file in place.`);
    return; // treat as non-fatal for tag cleanup
  }
  throw err;
}

When it happens

Trigger: deleteTag (via deleteFile) attempting to unlink a file that exists but cannot be removed: EACCES/EPERM on the file or its directory, EBUSY (file open/locked on Windows), EISDIR (path is a directory), or read-only filesystem (EROFS).

Common situations: Running as a user without write permission on the .taskmaster directory; another process (editor, sync client like Dropbox) holding the file open on Windows; the path actually being a directory; deleting from a read-only mounted volume.
