Jev Swap
0xjba · App
Jev Swap scans a TypeScript, JavaScript or Python codebase for LLM calls that are really decisions: calls that return an enum, a boolean, a small integer range or a yes or no answer. It estimates the cost and speed of moving each one to TypeSafe Jev, generates the converted code and shadow-tests it on recorded traffic. Runs against the real Jev need a TypeSafe API key, and a mock mode simulates it.

Why it's useful
It shows which of your LLM calls are plain decisions and lets you test a swap against your own traffic while requests still go to the real API.
What you could do with it
- Scan your app for decision-type LLM calls, such as a yes or no classification sent to OpenAI or Anthropic.
- Try the shadow test on a file of recorded samples in mock mode, which needs no API key.
- Point your app's OpenAI or Anthropic base address at the local proxy so live requests are mirrored to Jev.
Written from its documentation: what it says it can do, not what our checks found.
Maintenance
Not measuredNo release date is on record for this package yet. The nightly publisher check records one as it reaches each npm package, about once every ten nights.
Release activity only: it says nothing about quality or safety, and a finished small package can be fine without releases. How it is measured
What this does not cover
- Everything. Treat it as you would software from anywhere else.
Receipt history: every signed receipt for every version of this listing, and what changed between them.
In its maker's words
Find the LLM calls in your TS/JS or Python code that are really decisions, estimate their cost and speed on TypeSafe Jev, convert them, and prove the swap on your own traffic.

Static scanned
- What it establishes
- Its published package, or for a hosted server its source repository at a recorded commit, was read file by file, without running it, by every check in our current scan.
- What it does not
- How it behaves when it runs, or anything the scan does not read yet: several rubric checks, the repository's history, and compiled code in folders named dist or build. For a hosted server, that the endpoint runs the code that was read. The ooruby Index sets out exactly what was read.
- Exactly what was read
- Version 0.1.4, the file with digest sha512-ROXKrJfsGQctE585yD/0Fj+Sg1MnMqWBv29/QDCPN7w30BowE3z2JaVCyN4KuI+bx2iNil2+2fUUH5Dxor+7ug==, as the registry publishes it. A published version cannot be replaced, so this names the same bytes for anyone who checks.
- Authentication
- Runs locally. No hosted endpoint is listed for this package. You run it on your own machine, so there is no endpoint of ours to authenticate against.
Adding it
Run it with:
npx -y jev-swap@0.1.4Pinned to 0.1.4, which is the version the findings above were found in. Drop the version to take whatever is newest, and the report on this page stops describing what you installed.

No build provenance published. The repository above is the one the publisher declared, and nothing links it to the package you would install. That is not a mark against this listing, since most packages are published this way, but it is a check nobody can run.

It renders the current rung (static scanned) and links back here, where what that does and does not establish is one click away. It updates itself as the evidence deepens.
