pkg/agent/agent.go:13:2: no required module provides package google.golang.org/adk/agent; to add it:
Am I missing something here ?

I also hit this initially.
But now I tried this and it worked:

test$ go mod init example.com/m/v2
test$ go get google.golang.org/adk/agent

Perhaps something was fixed somewhere meanwhile.

We can add a Makefile rule, but locally I just use:

go install ./tools/syz-agent && syz-agent -workflow=patching -large-model=false -input=input.json -workdir=/tmp/syz-agent/

Looks like it yes!

Ah nice, thanks!

LGTM
I suggest that we do a follow-up change series to support K8S environment before the actual deployment on prod.
