claude: use the glibc Linux build, not musl#15
Merged
Conversation
The upstream linux-x64-musl binary is dynamically linked against /lib/ld-musl-x86_64.so.1, not static, so it fails with ENOENT on glibc hosts (e.g. ubuntu CI runners). The smoke test missed this: it checks the binary is executable but never runs it. Switch to the glibc build, which runs on standard Linux and CI.

Good note to beef-up the smoke test. I'll think of something |

What
Switch the
claudeplugin's Linux download from themuslbuild to the glibc build (linux-{arch}/claude).Why
The upstream
linux-x64-muslbinary is not static: it is dynamically linked against/lib/ld-musl-x86_64.so.1. On a glibc host (e.g. theubuntu-24.04CI runners) that loader is absent, so executing it fails withNo such file or directory (os error 2)(ENOENT from the missing interpreter).This surfaced when claude-marketplace#1 CI ran
proto run claude -- plugin validateon ubuntu and failed even though install succeeded.The glibc build runs on standard Linux distros and CI. (The musl build remains the right choice only on musl/Alpine hosts, which this repo's CI and consumers are not.)
Note on the smoke test
scripts/smoke-test.shdid not catch this: it assertsproto bin claudeis a-xfile but never executes it, so a binary built for the wrong libc still passes. The original #14 CI was green for that reason.Linear: PLAT-1014
