How long does the integration take?

Change one base URL in an OpenAI-compatible client, or install the Python or TypeScript SDK; the quickstart routes a first request in a few minutes.

Will this lock us into another vendor?

No. The router is Apache-2.0 open source, your provider keys stay yours, and the API is OpenAI-compatible, so leaving is a change of base URL.

What happens when a provider fails?

The router falls back to the next model your policy allows and records the fallback in the trace, so an outage costs a retry, not an incident.

About

Prompt file imported from thomasmixon2024/NEXUS-COVE (.github/prompts/nexus-validator.prompt.md). Copyright stays with the author.

You are the validation agent for this codebase.

Treat tests as the source of truth. Do not claim a fix is complete until you have run the narrowest relevant validation and reviewed the output.

Required behavior:

start with the most specific existing test or minimal repro
if no test covers the behavior, add one that exercises real behavior
verify the failure before the fix when appropriate
rerun the exact check after the fix
include the command and result in the final report

This repo requires:

pytest for behavior checks
compileall for syntax validation when relevant
ruff checks where the change affects style or imports
evidence before completion

Do not mark work as done based on confidence alone. Only say a change is working if the command output supports it.

Installed into a catalogue, chosen by a router

Install nexus-validator and it becomes one more candidate the router can pick - when it fits.

A listing is a routing target with a manifest: what it does, which domains it covers, what it costs and who publishes it. Once installed it sits beside your own models and tools, is scored like any other candidate for each request, and shows up in the trace when it wins. Ratings come from workspaces that installed it, one per account.

For the business

What it costs to adopt - in engineering time.

Same client, same code
One base URL
The OpenAI-compatible endpoint answers your existing SDK calls; model=auto lets the router choose.
The SDKs
One URL, every vendor
No vendor lock-in
Point your OpenAI-compatible client at one address; add, swap or retire providers in the catalogue without touching application code.
Every vendor side by side
Next eligible model answers
Failover built in
When a provider is down or over quota the request moves on; the trace says it did.
