Open the 接入方式速查 table in the README and find the row that matches your stack. 2. Read the linked official page for that row, such as the TypeSafe API docs, Vercel Evaluation docs, or TanStack Evaluate page. 3. Note the model or API identifier, for example `jev-latest` or `typesafe-ai/jev`, and the request and response schema for that route. 4. Check the migration reminder: confirm request schema, probability, confidence, threshold, and fallback behavior before switching providers. ### Prompt to paste into your agent ```text Using the Promethe-us/awesome-jev README, find the integration row that matches , and return the route name, model identifier, and linked official doc. Verify that the README notes the response schema differs from the native Choice, Score, and Noul primitives before you recommend it. ``` ### Caveat This is a community map, not an official TypeSafe AI project, and model, price, and status facts are dated snapshots to recheck on the official pages.

Read the 手把手 Jev guide in docs/HANDS_ON.md for state design, low-confidence fallback, and validation set steps. 2. Install the Python SDK with `pip install typesafe-sdk`, or use the JS/TS package `@typesafe-ai/sdk`. (inferred, check the README) 3. Define a Choice question with options such as cheap, strong, and escalate, and send a text state to `POST https://api.typesafe.ai/v1/systemone`. 4. Escalate to the strong model when the returned confidence is below your threshold, and log each decision. 5. Run the router on a labeled set of past tasks and compare routed results with the strong model's results before deploying. ### Prompt to paste into your agent ```text Using the Promethe-us/awesome-jev README and docs/HANDS_ON.md, draft a routing function for that sends each request to a cheap or strong model using a Jev Choice decision. Return the code and the confidence threshold you chose, then verify on a labeled set that escalation happens on hard cases. ``` ### Caveat Jev returns typed decisions with probabilities, but a typed output can still pick the wrong option, so the router needs a labeled validation set before it controls real traffic. Risk, credentials: Store the TypeSafe API key in an environment variable or secret manager and never commit it to code or logs. Disclaimer: Third-party repos we don't own or vouch for.

Read the 'Jev 在 Agent Loop 中的位置' section and the 'Jev 不是什么' list to confirm Jev is a decision layer, not a security boundary. 2. Open the Vercel eve evaluation guide linked in the 接入方式速查 table and review its `auto` and `evaluate` policy options. 3. Set a policy that sends uncertain or high-risk tool calls to a human, and enforces permissions in your own code. 4. Test the gate with blocked, allowed, and borderline tool calls, and confirm that tool execution never depends on Jev output alone. ### Prompt to paste into your agent ```text Using the Promethe-us/awesome-jev README, outline a tool-call gate for that uses Jev only as an advisory signal and keeps permission checks in application code. Return the policy steps and one test case per outcome, then verify that no tool runs without your own permission check. ``` ### Caveat The README states Jev is not a security boundary and not a physical robot safety controller, so permissions must live in your application code. Risk, credentials: The gate calls a paid, key-based API, so keep the key server-side and scope it to the gating service only. Disclaimer: Third-party repos we don't own or vouch for.

Open docs/ROBOTICS.md and list each drone, arm, simulator, and VLA item it names. 2. Sort each item into running, author-measured, or design-stage, following the page's own labels. 3. Open the linked source for each running or measured item and record what it actually tested. 4. Note that the README does not confirm a ROBOTIS brand integration, and mark any such claim as unverified. ### Prompt to paste into your agent ```text Using the Promethe-us/awesome-jev README and docs/ROBOTICS.md, produce a table of Jev robotics items for labeled running, author-measured, or design-stage, with source links. Verify that no ROBOTIS brand integration is stated as confirmed. ``` ### Caveat Robotics results listed here are author reports or early design work, so they do not show that Jev is safe or reliable on physical hardware.
