Stop signs: where your bot asks before it acts
Every bot plan needs a stop sign: the thing the bot must never do without you. Grok Bot gives you four places to put one.
This is part three of the Basics series. Part one, How do you plan a bot?, asks what the bot must never do alone. Part two, Create your bot, puts that answer in the description. This piece covers the checks that back the description up.
Why the description isn't enough
A description tells the bot how to behave. The bot can still technically do whatever its computer can.
"If you log into Amazon on a computer the agent can use, it can technically buy whatever it wants, the same way a human could," Matt Palmer, who works on developer relations at SpaceXAI, wrote in the official Grok Bot 101 guide.
So Grok Bot adds checks outside the bot itself. Here are the four you will see most.
1. The reviewer (Auto-review)
Palmer's guide says a separate review agent checks a bot's proposed actions "and can allow, block, or escalate to you." You write its rules in plain language. "You write the rules in natural language in Settings > General > Agent," he wrote, and allow and block lists steer the reviewer.
When the reviewer escalates, you get a card in chat. Since v0.56.0 (Sept. 17), those "Review an action" cards "say in one sentence what the Bot wants to do and keep the command and reasoning behind View the full request," according to SpaceXAI's changelog.
A few more things the changelog says about these cards:
- Auto-review asks before your bot runs a task you didn't ask for (v0.17.0, Aug. 12).
- Approval cards close when their time runs out (v0.52.0, Sept. 15).
- An expired Auto-review card offers "Always allow this in the future," so you aren't asked about that action again (v0.59.0, Sept. 25).
- In Slack threads, a bot that needs your approval posts a Review an action card "only you can answer" (v0.63.0, Sept. 29).
Tip: "Always allow" is a standing yes for that action. Use it for things you would never want to be asked about again, not to clear a card quickly.
2. Draft cards for email and Slack
Since v0.45.0 (Sept. 8), a bot can write an email or Slack message "as a draft for you to review, then Send or Discard it," the changelog says. Outlook drafts followed in v0.60.0 (Sept. 26).
As of v0.64.0 (Sept. 30), those draft cards also offer "Disable drafts for this Bot," which lets that bot send directly. You turn drafts back on by asking the bot. (Our story on that change.)
Tip: If your plan card says "never message customers," keep drafts on for that bot.
3. Purchase cards
"When your Bot wants to buy something, a card shows the amount for you to Allow or Deny, then Link completes the payment," according to v0.30.0 (Aug. 28). Since v0.33.0 (Sept. 1), "Pay with" lets you pick a saved card from your Link wallet.
Purchases you decline stay Declined, and unanswered ones are marked Expired, per v0.35.0 (Sept. 2). A declined, failed, or expired request "says no charge was made," per v0.40.0 (Sept. 3).
4. Your own computer
If a bot can reach your laptop or desktop, not just its cloud computer, you choose how much it may do there. Settings has a Computer section where you pick "Always allow, Ask every time, or Never allow for actions on each one," per v0.29.0 (Aug. 27).
Since v0.36.0 (Sept. 2), the changelog says, Always allow under Execution on this computer "lets your Bot use your computer without asking." (Our guide to local execution settings.)
Tip: Ask every time is the safe starting point. Move to Always allow only for a bot you have watched work.
One more limit: the shared computer
Palmer's guide says that "if you log into a site with one bot, every other bot can reach that site too." A stop sign in one bot's description does not stop a different bot. Put the rule in the reviewer's rules too. (More on the shared computer.)
Fill in your plan card
Using Penny, the made-up example from parts one and two, whose stop sign is "never reply to customers or close tickets":
In the description: Read only in the help desk. Never reply to customers or close tickets. If something is unclear, stop and ask me.
In the reviewer's rules: Block any reply or status change in the help desk.
Drafts: On.
Purchases: Penny never buys anything, so any purchase card is a Deny.
Your computer: Never allow. Penny only needs the help desk and Slack.
Your done-when for this step
You are done when every "never do alone" line on your plan card shows up in at least two places: the bot's description and one real check, such as the reviewer's rules, draft cards, or a computer setting.
