ax-llm · App

Ax is a TypeScript library for building with large language models in the style of DSPy. Instead of writing prompts, you define typed inputs and outputs, and Ax generates the prompt, streams and validates the answer and retries when needed, with the same code running on OpenAI, Anthropic, Google and other providers. It also handles images and audio, agents that call tools or other agents, multi-step workflows, prompt optimisation from examples and OpenTelemetry tracing. It suits TypeScript developers adding LLM features to their apps.

Written by ooruby from the README of @ax-llm/ax 25.2.1.

Not claimed by its maker. Is this yours? Prove it and answer the findings

Why it's useful

You write what goes in and what should come out, and the library handles the prompt, the parsing and switching between model providers.

What you could do with it

  1. 1Extract a ticket number, priority and sentiment from incoming customer emails as typed fields.
  2. 2Build an agent that answers questions by calling your own functions, such as a weather lookup.
  3. 3Give a program worked examples and let the optimiser tune its prompts automatically.

Written from its documentation: what it says it can do, not what our checks found.

Maintenance

Not measured

No 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

Not yet tested
Command execution is bounded
inventory
eval (skills/ax-agent-rlm.md:43)
An inventory of where the code starts another program, not a verdict on this row: whether each one runs a fixed program or whatever it is handed takes a reading by hand.
Licence and provenance
finding
no LICENCE file at the root (.)

Published because it was found. A finding is information about where the limits are, not a verdict that the software is unsafe.

How far this has been checked

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 25.2.1, the file with digest sha512-1r+n/Fi15kdkst06QXLFWjZPuo7txVl9JbN+eD5wmuN4tqW5IdHNy3ZkPgol08slOjAb37MgRsD093ywccWs7Q==, 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.
How the rungs work

Adding it

Run it with:

npx -y @ax-llm/ax@25.2.1

Pinned to 25.2.1, 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.

The badge, if this is your listing

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.
