Any Quickstart for Antigravity integration?

[Pringled]

Hi @wthernani, it should be as simple as:

uv tool install semble
semble install

Since we support Antigravity, it will show up as an option in the interactive installer, where you can choose which integrations you'd like to install. Are you encountering any issues with the installer?

Thank you for your time.

The installer works, but in Go-based MCP hosts like Google's Antigravity CLI, using uvx causes exit status 143 when the host stops the instance during reload because cmd.Wait() treats signal termination as an error. Additionally, in semble.mcp.serve, if stdin closes while the model prewarming thread is active, Python blocks on threading._shutdown() until SIGTERM kills it. Catching SIGTERM and doing os._exit(0) on EOF/SIGTERM makes it completely reliable on Go-based hosts.

As a workaround for now I'm using a semble-mcp wrapper that shields AGY from the Go signal-exit bug so /mcp reloads seamlessly.

Hey @wthernani, thanks for the clarifications. We're investigating this and will try to fix it in #282.
