About

Working Surface is a daily digest of links on how product, design and engineering teams work with agents. A scheduled job runs each morning at 06:30 Singapore time. It reads the list on the Sources page, searches the previous thirty-six hours, opens every page it intends to cite, and writes one issue with its links into a private workspace. A build runs an hour later, reads the rows marked for publication, renders the site as static pages and deploys it. The build writes no text of its own.

Every URL is opened before it is cited. The date shown for a piece is the date on the page, not the date the piece was found. Quotations are verbatim. A piece more than four days old is not cited as a receipt. Where a page is paywalled, only the open part is cited and the link page says so.

The headlines, summaries, key points, implications, suggested actions and daily notes are written by a language model and published without human editing. Suggested actions are derived from the article and are labelled as such, with the source line shown beneath them. No source has paid to appear and none has been paid. Nothing on the site is sponsored.

Each link's drawing is generated by an image model from a one-sentence description of a scene in the article, in one fixed style: pen and ink in cobalt blue. The paper is neutralised to white and the ink alone is printed onto the card. A link with no scene has no drawing. No drawing depicts a real person.

Working Surface checks the practices on the Practices page with Jev, an AI model made by the company TypeSafe. Jev reads the practice alone, without its article, and answers three questions with a probability. Would someone who has not read the article know what to do? Could a team start doing it this week? Does it name the step, the thing that changes and who does it?

A practice passes when Jev puts the first two answers at 0.5 or more and rates the third as concrete or better. The practices that failed the first check, on 29 September 2026, were rewritten and checked again. In each topic, the Practices page lists first the practices Jev found clearest.

The check covers clarity only. It does not judge whether a practice is right or how important it is. Hovering over a practice on the Practices page shows its three scores, each against the pass line.

The Ask page answers questions from this site's links only. First, Jev, TypeSafe's model, reads a one-line index of the site and picks up to three links for the question. Then Gemini 3.5 Flash-Lite, an AI model from Google, writes the answer from those links' records alone and names each link it uses.

Answers can be wrong. The links are the record, and each answer links to them.

The question goes to TypeSafe and to Google. Ask uses Google's free Gemini service; under Google's terms, questions sent to it may be used to improve Google's products, and human reviewers may read them. Do not type personal or confidential information. Working Surface does not store the questions.

Google's terms do not allow the free service to be offered in the European Economic Area, Switzerland or the United Kingdom, so Ask is closed there.

The free service allows about 500 answers a day. When they are spent, Ask rests until midnight Pacific time, which is 3 pm or 4 pm in Singapore.

Kind. Company story, for how an organisation changes with agents; How-to, for a pattern decision relayed from the team that made it.

Topic. A recurring idea followed across issues, with a short name, a definition and the links filed under it.

Issue. One day's note, kept as written.

Practice. An action a linked article describes, written by Working Surface and tagged for product, design or engineering work.

Shipped. A release that changes how teams work: a feature in their tools, a new AI model or a major AI-lab product, logged with the date on the maker's page.
