Install an agent from the Marketplace and adapt it

Why start from someone else's agent

You do not always need a blank page. Marketplace packages give you a working design to learn from and change. Treat any package the way you would treat a stranger's code: read it before you trust it.

Steps

1. Choose Agents, then New agent, and scroll to From the marketplace.
2. Search, for example for "digest", and read the summaries.
3. Choose Use this agent on one that suits you. You land on the new agent's page.
4. Read before you run. Check the Instructions, and look at Tools: which are ticked, and which carry Needs approval? Does it need PGB Business access? Check Budget and Triggers.
5. If it has a schedule, it starts paused so you can review it. A warning banner says so. Nothing will run on its own until you choose Resume (then save) and Save changes.
6. Run it once by hand and read the trace.

Adapt it

Use the same improvement loop you learned for your own agents:

1. Change one thing, such as the output shape, the sources it reads, or the tone.
2. Remove tools it does not need. Least privilege applies to someone else's design too.
3. Lower the budget to suit you.
4. Fill in PGB Business access only if you want the mail or calendar tools, using a narrow key.
5. Save and run it again. Compare the traces.

Questions to ask about any package

• What can it do? List the tools.
• What can it do without asking? Which tools carry Needs approval?
• Where does it send data? Look for web and connected-server tools.
• What does it cost to run? Check the budget and run it once.
• Could I explain what it does to a colleague?

Check your work

• You can state, in one sentence, what the installed agent does and which tools it uses.
• You removed at least one thing it did not need, or confirmed that everything was needed.
• It ran by hand before you let a schedule run it.

What you learned

• Marketplace agents are a head start, never a black box.
• Review, narrow, lower the budget, run by hand, and only then schedule.
• Anything you adapt becomes yours to maintain.
