What it does

  • Measures app caches, updater downloads and leftovers from removed apps
  • Drills into browser profiles, developer caches, Docker and simulator data
  • Separates rebuildable caches from drafts, credentials and personal files
  • Writes a table with size, safety rank and what you lose by deleting

Read only

Reads connected data. It does not send messages or change records.

More about this workflow

This setup is for busy people who want their own day to run a little smoother. It takes a repeat chore off your plate and hands back something you can check quickly.

First, it measures app caches, updater downloads and leftovers from removed apps. Next, it drills into browser profiles, developer caches, Docker and simulator data. Then it separates rebuildable caches from drafts, credentials and personal files. Finally, it writes a table with size, safety rank and what you lose by deleting. It works with your docs, each on its own login with limited access.

You get the finished work, ready to read. It only reads, so nothing is sent, changed or paid for. You decide what to do with it.

“It does not delete files, quit apps, stop services, or run cleanup commands.”

3 of 3 still empty
Fill these in before you run it: [DISK SPACE GOAL] [FOLDERS TO SKIP: e.g. photos library] [APPS YOU STILL USE] You are the Mac storage audit ranked by deletion safety agent. Explains what is filling your Mac and ranks cleanup candidates from safest to most cautious. It deletes nothing, so you choose what to remove and do it yourself. Use only the details filled in above. If any [BRACKETED] item is still blank or unclear, stop and ask for it first. Do not guess. What you do on your own: - Measures app caches, updater downloads and leftovers from removed apps - Drills into browser profiles, developer caches, Docker and simulator data - Separates rebuildable caches from drafts, credentials and personal files - Writes a table with size, safety rank and what you lose by deleting What you must never do without a yes from a person: - Anything that writes, sends, or spends. This job only reads. Rules: - Before any step on the list above, stop and ask. Say in plain words what you want to do, who it affects, and whether it can be undone. - If something cannot be undone, say so first, in one short line. - Write drafts, not final actions. A person sends, pays, posts, or deletes. - Keep a short log of every action you took and every source you read. - If you are unsure, ask instead of guessing.

Run your workflow

Connect your tools with only the access this setup needs, then follow these steps.

Steps

Do these in order. Test on old data before it touches live work.

  1. 1Connect Google Docs with its own login, not yours. Grant one folder, create and edit only.
  2. 2Paste the prompt where your harness takes instructions. See the note under the Copy button.
  3. 3Do a dry run on old or test data first. Check every draft and every stop point by hand before you let it near live work.
  4. 4Read its log after the first real run. Only widen access once a week of runs looks clean.

Safeguards and trust score

The score describes this example setup’s access, approval boundaries, ability to undo changes, and scope.

Access30 / 30

Read only. It never writes, sends or spends.

Human approval30 / 30

Nothing to approve, it only reads.

Undo and logs20 / 20

No changes to undo. Reads can be logged.

Scope20 / 20

Runs on its own login across 1 tool. Fewer connections means a smaller blast radius.

How to raise it

Nothing major to fix. One polish tip: show a short daily log of what it read, so you can spot it reaching for anything new.
