fix(hooks): skip hook injection when /bin/sh is absent - #274
Merged
Conversation
In remote container environments (e.g. CloudStudio AI inference nodes),
/bin/sh may not exist. CodeBuddy executes hooks via spawn('/bin/sh'),
so every hook invocation fails with ENOENT (error 1001), blocking all
user input.
Detect /bin/sh availability at install time and skip hook injection for
shell-dependent tools (CodeBuddy/WorkBuddy) when absent, with a clear
warning. Other tools (Claude Code, Cursor) are unaffected.
