What the code does
We read the source, 2 d ago · rules 995398eba69f
Found in continuous integration, deployment or infrastructure files, or in a neighbouring package of the same monorepo. None of this is installed when you add the server: it describes how the project is built and released. We list it because a leaked key in a build pipeline is still a real problem, but it is not something this server does on your machine.
"!pip install -q google-genai==1.36.0 google-adk==1.14.1\n",
Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.
This one has been quiet for a while
Quiet is not dead — but it is worth knowing when it wakes up, or when someone else takes it over. We watch the repository and tell you either way.
