What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of buildstackweekly.com controls every word below.

Recommend a stack

Recommends three tools from the checked guides, the same picker as the Pick my stack quiz. Pass a project description or the quiz fields building, comfort, data, budget, surface, and timeline. Unconfirmed prices stay TBD.

Examples it gives

a waitlist page that saves emails
building=webapp comfort=none data=yes budget=free surface=web timeline=weekend

Get a tool

Looks up Lovable, Bolt.new, v0, or Cursor from the published sample. Cursor was not picked in issue 0, so that record has no URL or price. Later guide pages can price a tool. Those pages are on /api/tools under guides. Pair pages are under comparisons.

Lists published issues, including the sample.

newsletter

Adds an email to the newsletter through the same beehiiv signup as the website. If the API is not configured, it returns the public subscribe page.
