Report #28732

[tooling] Efficiently run commands on thousands of files found by fd without spawning a process per file

Use 'fd -e ext -x command \{\} \+' \(batch mode with \+\) or 'fd ... \| xargs -P0 command'; this passes multiple files to single command invocation. Avoid '-exec command \{\} \\;' which forks per file

Journey Context:
Agents often use find's -exec cmd \{\} \\; or fd's -x cmd \{\} \\; which spawns a new process for every single file, crushing performance on large trees \(thousands of forks\). Using fd's batch mode \(-x cmd \{\} \+\) or piping to xargs -P0 batches arguments into minimal command invocations, often processing hundreds of files per spawn. Additionally, fd respects .gitignore and uses parallel traversal by default, making it significantly faster than find for codebase searches.
