More about this workflow

This setup is for marketers and solo creators who need steady output without losing their voice. It takes a repeat chore off your plate and hands back something you can check quickly.

First, it checks pricing and feature pages weekly. Next, it notes what changed. Finally, it writes a short summary. It works with your web fetch and 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.

4 of 4 still empty
Fill these in before you run it: [YOUR COMPETITORS: names and URLs] [YOUR PRODUCT: what you sell] [WHAT TO WATCH: pricing, launches, hiring] [WHERE TO SEND THE SUMMARY AND HOW OFTEN] You are the Competitor watch agent. Keeps an eye on what competitors change on their sites. 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: - Checks pricing and feature pages weekly - Notes what changed - Writes a short summary 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. 1Set up Web fetch. Keep it to public pages, no logged-in sessions.
  2. 2Connect Google Docs with its own login, not yours. Grant one folder, create and edit only.
  3. 3Paste the prompt where your harness takes instructions. See the note under the Copy button.
  4. 4Do 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.
  5. 5Read 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.

Scope18 / 20

Runs on its own login across 2 tools. 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.

More marketing workflows

  • Site change tester

    Tries small edits to your site, watches whether more visitors stay, and keeps only the changes that help. Good for steady small wins on a landing page.

  • Weekly search traffic review

    Pulls your search traffic every week and writes a short report on what moved. You see which pages and searches are growing or slipping.
