Summary · 摘要
Security hook for coding agents: before each tool call Jev judges how much harm it could do, whether the user asked for it and whether it follows untrusted text, and code denies, asks or allows; afterwards Jev scans the result for prompt injection. For Claude Code, Codex, Cursor and more.written by a model
给编程智能体用的安全钩子：每次工具调用前，Jev 判断这次调用可能造成多大危害、是不是用户要求的、是否在执行不可信的文字，再由代码决定拒绝、询问还是放行；调用返回后，Jev 扫描结果中的提示注入。支持 Claude Code、Codex、Cursor 等。模型撰写机翻

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/jev-guard.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.
Cua driver: jev-use example
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.
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.
