Summary · 摘要
Computer-use action selection in Python and TypeScript: Jev picks the next browser action from an immutable candidate set, with reobserve and abstain as reserved options.
Python 与 TypeScript 双实现的 computer-use 动作选择：Jev 从不可变候选集里挑下一个浏览器动作，保留 reobserve 和 abstain 两个特殊选项。
Notes · 备注
Worth copying its rigour: it validates that every probability is finite and in range, rejects an answer outside the candidate set, sends typed bounds instead of screenshot bytes, and ships a mock adapter so the whole loop runs with no key and no network.
它的严谨程度值得照搬：校验每个概率有限且在区间内、拒绝候选集之外的答案、发送类型化坐标而非截图字节，还提供 mock 适配器让整个循环无密钥无网络也能跑。

The same form takes the product's one line and a demo link, in its maker's own words. 同一个表单也可以补上产品的一句话和演示链接，用 Maker 自己的话。
Badge for its README · README 徽章
[](https://kydlikebtc.github.io/awesome-jev/products/cua-jev-use.html)One line for the product's README, linked to this page. The picture says that it is listed; while it is on the launch board, that it is launching; after a week in the top three, its place. It is rebuilt with the site, so the line never needs changing. 放进产品 README 的一行，链接到本页。图片显示已收录；在发布榜上时显示正在发布；进过某周前三后显示名次。它随网站一起重建，这一行不用再改。
Also under this pattern · 同一模式的其他产品
ai-hedge-fund
Educational paper-trading and backtesting app whose investor-persona agents turn a financial snapshot into a bullish, bearish or neutral signal. With TypeSafe as provider, one Jev request per agent asks a choice of direction and a five-level score of each case's strength, mapped to the agents' JSON.
claude-code-templates: three Jev plugins
Three independently installable Claude Code plugins — guardrails, model router and skill suggestion — each with its own hooks and tests.
Composio TypeSafe provider
Compiles a tool catalogue into questions and reconstructs tool calls from the answers, with typed errors for abstention and confirmation-required cases.
FastMCP jev_search transform
Two-stage MCP tool search: a wide Choice coarse-ranks the whole catalogue, then a shortlist gets full descriptions plus one Noul each to decide whether it does the job at all.
jev-ultrafast
A high-speed browser agent from Browser Use: Jev decides the operation and which element to act on, and a small LLM is called only when text must be typed.
