It just requires Agentish - the agent’s native tongue, the LLM’s lingua franca - frickin plain text.
And honesty. About what it can do (everything on the web, besides stuff only you can do), and what it can’t do, but you can: MFA, captcha, login.
An agent skill with smart guardrails and a well designed Unix philosophy CLI tool is enough to power any task on the web.
You can try it too. Here’s some things I’ve thrown at it and it’s done:
- find at least 100 relevant tweets and craft apt replies that promote WebCLI to people experiencing the pain it solves Grok Build with Composer 2.5 Fast
- Compare flights from SFO to DC mid afternoon across a couple of providers like Google flights and kayak, etc.. Find the cheapest one with no stops. Fill in my details and book it but stop at payment. Codex 5.5 high
- Find some fun Lego products across amazon Walmart Alibaba and lego.com and find the coolest set or large quantity of blocks at the best price and take it all the way to checkout filling in details. Claude Sonnet 4.6
And many more. The agent’s always figure it out. No screenshots no selectors, just raw text and numbered references for actions with honest in validation and a bunch of useful surface.
The core loop is a simple OODA loop:
web inspect # agent observes and orients
web do <ref> <opts> # agent decides and acts
It’s a new era of web task driving with intelligence. No more playwrights and puppets, no more robotic “auto-mation” beep boop. WebCLI is web improvisation, powered by agents’ intelligence.
I want to keep building technology for agency. Imagine if you tried this tool and it saved you time and drudgery. Try it and then pay because it’s valuable. You get a free, fully functional five day trial per email domain, with just email. Https://webcli.sh
