What it does

  • Proposes small page edits
  • Runs each one for a set time
  • Compares how long visitors stay
  • Recommends keep or roll back

Your approval boundaries

Approval required

These actions always wait for your yes:

  • Publishing any change to the live site

You decide what happens next.

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 proposes small page edits. Next, it runs each one for a set time. Then it compares how long visitors stay. Finally, it recommends keep or roll back. It works with your git host and analytics, each on its own login with limited access.

You get the prep work done and waiting for you. The agent stops and asks for your yes before publishing any change to the live site, and says plainly if a step cannot be undone.

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 GitHub with its own login, not yours. Grant a fine-grained token, read code and write comments.
  2. 2Connect Google Analytics with its own login, not yours. Grant Viewer role.
  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.

Access18 / 30

Can draft things that send or spend, so it sits close to risky actions.

Human approval27 / 30

Waits for a yes on: publishing any change to the live site.

Undo and logs14 / 20

Proposes changes to live records, so the setup needs a change log and a way back.

Scope18 / 20

Runs on its own login across 2 tools. Fewer connections means a smaller blast radius.

How to raise it

  • Access: Take away its ability to send, post or spend. Let it only write drafts, and have a person press send or pay from their own account +6
  • Human approval: Add a second named stop next to "publishing any change to the live site", so every step that leaves your hands waits for a yes, and have the confirm say plainly what cannot be undone +3
  • Undo and logs: Stop it from editing live records. Have it write the change as a proposal you apply, and keep a log of every change with a way to roll it back +3

Do all of these to reach 89, up from 77.
